gas fuel steam boiler 4 ton

The main structure of the internal combustion boiler detail: In the combustion boiler is a main flue of all, combustion residue after combustion of the fuel without directly heating the surface of the mixed working fluid is heated and the flue gas, together with steam as the working fluid work output of method of operation, high efficiency boilers. The internal combustion boiler thermal industry is part of the production of steam. Next to be described in detail the structure of the main combustion boiler: a boiler shell, the pressure receiving member is an important potshell shell type boiler, it is the role space for storing water and soda and steam are separated place. In shell type boiler, boiler shell placed combustion chamber (furnace) and the heating surface, the effect of which was underway boiler body. Potshell cylindrical container is made of welded steel sheet, we split it into three parts: the cylindrical portion is an intermediate portion, both ends of the tubesheet portion is simplified, and some people open end of the tube sheet hole. Simplified by the two or more tube sections butt weld made, the minimum length of the barrel section is not less than 300mm. When the boiler is greater than the inner diameter of the shell boiler 1000mm. Simplified access potshell wall thickness should be not less than 6mm, inner diameter of the shell when the pot is not more than 1000mm, simplified access to the boiler shell thickness is not less than 4mm. Both sides of the drum and the tube plate is connected to the boiler shell simplified, many small holes drilled in the tube plate, through the hole in the fire tube. Front tube plate further defines a larger hole furnace connected. There are many simple pan upper takeover, which takes over a main steam valve, safety valve, manometer, water gauge and the like. Pan with water separator housing interior, surface sewage, and the like into the water. 2, furnace, furnace boilers are specific shell type pressure element, inside a furnace combustion chamber, the outer coating from the boiler water. Furnace outside the furnace by the water pressure. Therefore, it is the worst working conditions the pressure element shell type boiler. Because the furnace by the high temperature flame burning, the temperature is higher than the temperature of the boiler shell, its thermal expansion problems particularly prominent in the boiler fuel, the oil combustion temperature is high, a high furnace thermal strength, severe temperature changes, there is required furnace good performance thermal expansion and contraction. General furnace are made waveform. And some shell type boiler or furnace to a flat circular flat circular shape Singapore. 3, fire tube, the main fire tube boiler heating surface of the boiler shell. Generally use is made of boiler steel φ51mm ~ φ102mm, the front and rear tube plate by welding or play mode coupled expanded joint, when Expansion, connecting the fire tube and inflation port after inflation tube plate using 90 ° pull side contact. Front and smoke at a relatively low temperature plate, inflation bell mouth pull side can be connected. When a welded connection, in order to ensure sufficient bonding strength, and the tube end is not overheating, the tube end projecting required length of the tube plate is not less than the wall thickness plus 1.5mm, but not in excess of the connecting seam 5mm. Imported oil-fired boiler, and some in the furnace exit, fire tube to tube sheet welding connection. But in other parts of the fire tube to tube plate with flange 90 connected to the expander. Effect is produced outside the smoke tube of the tube furnace heated by flue gas through the combustion water in the tube, in order to gradually generate steam, also called "squib." Generally have the following forms: a straight barrel, also called "light pipe", the advantage of a small light pipe smoke resistance, the disadvantage is fouling the inner pipe easily. Heat transfer effect is also poor. Light pipes are typically seamless steel tube, but also useful for welding boiler tube inlet. Another is a threaded tube, which is pressed inwardly out of a recess in the seamless pipe, it seems like a thread, so called "threaded pipe." The advantage is that the flue gas flow within the tube, changing the flow cross-sectional area, the flow velocity of flue gas is also changed and swirl effect. Therefore, it is better than the light of the heat transfer tube and hard fouling. The disadvantage is greater than the resistance through the light pipe has a certain velocity before the flue gas swirl effect more obvious. The third is to add steel wire or steel wire to the formula Fu light tube. It is a light pipe inside the tube into a tube-type inflammation oxidation resistance good steel wire, inside the flue gas flow at the fire tube, steel wire plays a role similar to the threaded tube. If you want to fire tube cleaning, can easily be removed steel wire, steel wire and light pipe are more convenient cleaning. This form of fire tube easy to manufacture, simple maintenance. In order to maintain the strength of the tube plate, according to strength calculation, be reinforced hole in a predetermined position region of the tube plate. Specific fire wall is thickened, with a thick-walled welded tube to tube plate, so that both as reinforcement, acting also as heating surface, the thick-walled tubes referred to as "bracing tube."

Are gas-fired fuel steam boiler 4 tons environmentally friendly? Gas-fired steam boiler, which can be regarded as a gas-fired boiler, can also be regarded as a steam boiler. This boiler, from a professional point of view, is an environmentally friendly boiler, compared to oil and coal-fired boilers, because it uses gas. Moreover, the thermal efficiency of this kind of boiler is very high, can reach more than 90%.

Jilin Province is located in northeast China, colder winter. Jilin Province is the autumn and winter air pollution problems are most acute period is the peak period of fog and haze. To reduce the frequency of occurrence of fog and haze, to reduce emissions of air pollution, according to "implement the central Jilin Province Environmental Protection Inspector feedback reform program", Jilin cities to carry out the 2018 autumn and winter special law enforcement inspection of non-electric coal-fired boilers. Specific implementation of the program as follows.

2018 autumn and winter non-electric coal-fired boiler special law enforcement inspection action plan

First, the objectives

Through the "2018 autumn and winter special law enforcement inspection of non-electric boiler coal" action to further increase the intensity of emissions of air pollutants such as excessive penalties for violations combat, urge local governments and environmental protection departments to effectively implement the "Jilin province to implement the central environmental protection inspector feedback reform program, "Forced enterprises to speed up 10 tons of steam coal-fired boilers small and out of more than 20 tons of steam and non-electric coal-fired boiler pollution control facilities upgrade progress to ensure stable discharge standards.

Second, the scope of the inspection

Cities (prefectures) and Changbai Mountain Administrative Committee, Meihekou, Gongzhuling City, Hunchun.

Third, check the time

2018 Nian September 1 to November 30.

Fourth, inspection methods and content

Cities (prefectures) and counties under the jurisdiction of Changbai Mountain Administrative Committee to set up inspection teams to units in the area to take a cross peer review mode, Meihekou, Gongzhuling City, Hunchun to self-oriented.

The principle of mutual cross-check on the environmental violations found, the city's environmental protection departments at all levels in accordance with "should check to make investigation, should make a fine penalty, should be moved to make-shift" of errant given time out of the boiler, not dust removal facilities renovation no construction of desulphurization facilities are not required to install, networking, using automatic monitoring equipment, excessive discharge of pollutants and other acts take full advantage of "environmental law" and supporting measures to implement daily basis penalties, limited production shutdown, sequestration, administrative detention measures to deal with.

Focus on examination of the following:

(A) the progress of 10 tons of steam coal-fired boilers little out of work. According to "implement the central Jilin Province Environmental Protection Inspector feedback reform program," according to the time limit set by local governments, the progress of the phase-out of coal-fired boiler 10 tons of steam since 2014, the province's illegal 1570 newly registered units to be checked.

(B) more than 20 tons of steam coal-fired boiler non-electric dust removal, desulfurization facilities upgrade progress, automatic monitoring equipment installation, networking, usage. By ShengTing 6, July scheduling, the current to complete the rectification stage 717, stage 108 does not start the rectification, the rectification is 277, automatic monitoring equipment table 140 is not installed, the slow progress of the rectification. To complete the transformation around the boiler on-site verification, focusing on inspection facilities dust removal, desulfurization facilities upgrading and installation of automatic monitoring equipment, networking, usage. Percentage being modified, check the current progress of the major transformation of the situation, progress of the project, the time frame for completion, safeguard measures taken, it requires the use of boiler units issued commitments. For failure to start the transformation, to identify the main reason for not starting. If we do not transform the way in which the pin number to take all necessary construction and renovation tasks must be completed in accordance with the requirements of 30 September.

(C) boiler emissions standards. To install automatic monitoring equipment to monitor them than to confirm the validity of the data. For failure to require the installation of automatic monitoring equipment, shall be punished in accordance with relevant laws and regulations, at the same time supervisory monitoring, to determine whether to achieve a stable discharge standards.

Fall and winter heating season is the peak of Jilin Province, to ensure the normal heating units, we must also pay attention to boiler problems in the process of environmental protection. For the high-emission, high-polluting coal-fired boiler and other fuel boiler, to be banned or corrective action.

What are the overall structure of the boiler boiler structure includes two major boiler and auxiliary equipment. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. The furnace cross-section is generally square or rectangular. Combustion fuel to form a flame in the furnace and high temperature flue gas, so the hearth around the furnace wall is made of refractory material and insulation material. On the inner surface of the wall of the furnace waterwall tubes often laid, it will not burn both protect the furnace wall, and absorb a large amount of radiation heat of the flame and the high temperature flue gas. Furnace design needs to fully consider the characteristics of the fuel used. Each boiler should be fueled with the original design of the fuel. Boilers running economy and reliability are likely to vary greatly reduced when using the characteristics of fuel combustion. And the natural circulation drum is repeatedly forced circulation boiler receiving feedwater to the economizer, the coupling cycle and supplying saturated steam superheater cylindrical vessel. Simplified drum made from high quality steel plate, is one of the heaviest components of the boiler. The main function of the water storage drum, a steam separator, brine and water excluded pot sludge in operation, to avoid the boiler water containing a high concentration of salt and impurities entering with the steam superheater and a steam turbine. Internal drum means comprises a moisture separator and a steam cleaning apparatus, water distribution pipes, sewage and dosing equipment. Wherein the effect of soda is separated from the water wall by means of saturated steam and water to leave, and to minimize the steam carried fine water droplets. Low pressure boiler used as a crude flap and slit baffle separating element; above except pressure in the boiler is widely used for various types of rough separation cyclone, but also with blinds, steel mesh plate or the like are vapor further separation. The drum is also equipped with water gauges, safety valves and other monitoring and protection facilities. In order to improve the design and performance assessment, often have to go through boiler thermal balance test. Direct methods to calculate the thermal efficiency of the boiler is called n-efficient use of energy balance, the heat loss from a variety of methods to counter the counter balance called computational efficiency. When considering the practical benefits of the boiler room, boiler thermal efficiency not only look, but also taking into account the energy consumed by the auxiliary boiler. Fuel per unit mass or unit volume of complete combustion, calculated according to the chemical reaction called the theoretical air quantity of air required. In order to have more opportunities to the fuel in contact with oxygen in the furnace combustion, the actual amount of air into the furnace is always greater than the theoretical air amount. While air can be reduced into a multi incomplete combustion heat loss, but the heat losses will increase, also exacerbate corrosion of sulfur oxides and nitrogen oxides generated. We should therefore seek to improve combustion technology, as small as possible in order for the excess air ratio in the furnace so that complete combustion. Dust contained in the boiler flue gas (including carbon black and ash), sulfur and nitrogen oxides are air pollutants, which can achieve emissions targets environmental regulations when unpurified indicators several to several tens of times. These substances emissions control combustion pretreatment, improved combustion techniques, dust removal, desulfurization and denitration. By means of a high chimney stack can reduce the concentration of pollutants in the atmosphere of the area. Flue gas dust removal force used gravity, centrifugal force, inertial force and acoustic adhesion, static electricity and the like. Is generally used for separating coarse particles gravity settling and inertial force, centrifugal separation is often used dust bag filters and electrostatic precipitators having a high dust removal efficiency at higher capacity. Wet venturi - water film adhering water film droplet precipitator ash, high collection efficiency can absorb gaseous pollutants. Since the 1950s, people strive to develop the comprehensive utilization of ash, harm into. The manufacturing cement, bricks and building materials such as concrete aggregate ash. Since the 1970s and from the fly ash cenospheres extracted as a fire-resistant insulation and other materials. Future development will further improve boiler thermal efficiency of boilers and power plants; reduce equipment cost per unit of power boilers and power plants; enhance operational flexibility and level of automation of the boiler unit; develop more varieties to suit different boiler fuel; and improve boiler unit the reliability of operation of the auxiliary equipment; reduce environmental pollution.
