Gas Fired Industrial Steam Boiler with Low Nox Burner

Gas Fired Industrial Steam Boiler with Low Nox Burner

Method for safe operation of fired industrial steam boiler with low nox burners steam boiler before use, must be checked for damage of the insulating layer, to check the burner is operating correctly, and to check the position of the opening degree of the valve to ensure it is correct. Must be checked for automatic control instruments and equipment safety equipment accessories, equipment, in order to comply with the requirements. Check item prior to ignition of the steam boiler: open valve before oil circulation pump, oil heating valve is opened, adjusted reasonably high level of the tank, the gas pressure is determined before the natural gas burner ignition must be within the range, the power good . Refers to the operation of the steam boiler is refluxed pressure activated device circulating pump, the circulating pump outlet, inlet, outlet, and the system, it is in the normal range. Circulation pump run for 30 minutes. After the stability of the system, the next step. Open the gas tube steam boiler manual valve, button start-up burner, natural gas burner into the furnace, and then the ignition, the flame remains stable, i.e. is in a safe operating condition. In the firing process steam boiler, if you accidentally quenching phenomenon occurs, the device will automatically interlock burner saver appear. It must be promptly cut off the natural gas pipeline to start the furnace purification. Replacement of the residual gas in the furnace and closed. The system load requirements, temperature requirements and thermal oil outlet, the burner can automatically adjust the size of the fire source.

The main difference between the gas boiler and gas fired industrial steam boiler with low nox burner What is the main difference between what gas boilers and gas steam boiler is? Nominally, a clear distinction between gas and steam boiler wherein the boiler fuel gas is different. The former use of natural gas, which uses coal. I think a lot of user concerns boiler is why they should cancel gas-fired boiler, because many people have purchased and used the gas boiler. If they switch to gas-fired boiler, it will be a huge expenditure. First, according to the current direction of development of the ecological environment of China, gas boilers will gradually be replaced by gas-fired boiler or other clean and green energy boilers, gradually withdraw from the stage of history. To say a big difference between the gas boiler and gas steam boilers, gas-fired boiler is mainly due to the elimination of environmental protection. From the fuel supply portion, only a gas boiler tube connected to the boiler; gas boiler needs coal field, coal (with or artificial), coal transportation, handling, storage and loading of coal boiler process. It will produce dust, causing serious pollution to the people's living environment. From the point of view of atmospheric emissions, natural gas is very small dust content, substantially negligible; high ash content of coal, the ash content of about 10-30%, the combustion smoke. If dust emission reduction facilities, emissions will increase; if more dust removal facilities, the corresponding costs will increase, this is not a long-term solution. In addition, the sulfur content of natural gas is very small, dust removal, desulfurization and denitrification can get gas boilers, gas boilers need only consider the denitrification problem. From the other point of view of waste disposal, natural gas substantially free of other contaminants, especially in city gas. In the case of coal, the coal field (especially small boilers mainly built in the open air) to produce coal slurry water during the rainy season, or sink into groundwater. When entering the surface water, the combustion ash conveyance of dust is generated. Of course, there are differences also in other ways. For small boilers, gas boilers are more energy efficient than gas boilers, equipment flow is simple, small footprint, low operating and maintenance costs, and so on. These are the main difference between the gas boiler and gas steam boilers, as well as the significance out of gas boiler. As can be seen, the use of gas-fired boiler is the trend of the whole society.

In recent years, Hebei Province People's Government to respond positively to Blue Sky Battle action plan promulgated by the state, and all of 35t / h coal-fired boiler and below in the Hebei province out of the transformation process. First Hospital of Baoding respond positively to the call of the provincial government, eliminate serious pollution of the original coal-fired boiler hospital, citing energy saving fired industrial steam boiler with low nox burner to natural gas as raw material. After a series of market research, WNS Series Split hospital condensing gas boiler boiler other fast soft spot.

What is the reason for fired industrial steam boiler with low nox burner explosion? Boiler itself is flawed: the pressure component aging, strength weakened, or leakage, corrosion, deformation, scaling and other defects can not be timely maintenance and eliminate hidden dangers, but let the disease run with the boiler and so on. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. Therefore, we must carry out regular inspection of boilers in accordance with national requirements. 3. poor management, furnace workers irresponsible or low levels, lead to misuse. Therefore, furnace workers must obtain a certificate as required. None of the above is the main reason for the actual boiler explosion. In actual operation, the most common situation is that the boiler add cold water and drying, which is very dangerous. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. This is also the operators need the most important thing vigilance. There may be debris blocking the pressure cooker vent, causing the pot to continue to increase pressure, excess pressure can not be discharged to reach the pot of strength, can withstand the pressure will naturally explode, of course, does not rule out the cause of pan itself. Substandard quality, tank leaks, inadequate exhaust usually cause an explosion. Therefore, before use, carefully check the vent is smooth, not to violate the specification and taboos, without any danger.
