To accelerate the low nitrogen transformation gas boiler in each area of Xian, October 23, 2018, liberation of the door street in charge of leading Korean right lead a public person with low nitrogen regional transformation slow the unit door butt again, and supervise the various units to speed up progress, by the time limit to complete the task of transformation.
1, Imperial Square area, parking building, Suntech Lane three projects reflect seven plots site inspections carried out two times, road construction site clean and moist, well-covered, site supervision and regular opening spraying dust and other facilities, strict implementation of air pollution control measures.
2, the region west of Seven Road, Sheung Tak Road, west along the eight dining pollution checks to ensure that all food and beverage outlets normal use of fume purification facilities, and urge all stores on a regular basis to do routine maintenance.
Water wall boiler tube leak or burst phenomenon how to do 1, the normal water flow is not greater than the steam flow. 2, the furnace pressure transient and unstable prejudiced. 3, tube leak detection alarm device. 4, the furnace may not tight at the outward discharge gas and water vapor, and a significant leakage sound. 5, the main steam pressure drop. 6, boiler combustion dark flame instability caused by severe boiler fire. 7, when the induced draft fan is automatically cast, abnormal static vane opening is increased, the current increases. 1 reason, the presence of water wall tube material defects or post-production, the installation of the damaged pipe, poor welding quality. 2, the inner tube fouling overtemperature. 3, the inner tube corrosion. 4, water wall wear. 5, the long-term high load operation, furnace coking, coal sulfur corrosion caused by high temperature water wall. 6, improper combustion, flame deflection. 7, in the possession of bad foreign body, the water cycle. 8, the wall of the long-term over-temperature operation. 9, the temperature difference between waterwall tubes, mechanical stress crack. 10, the normal exit or drain sootblower steam punctured tube. 11, smashed chunks of coke furnace water wall tube or serious explosion occurred, resulting in water wall tube suffered external damage. 12, boiler overpressure long run. 13, the boiler starts to heat up, step-up too fast. 1 process, the leakage should try waterwall tubes outage. The leakage is not serious, while still capable of maintaining operation, note that each of the automatic operation when the device, if not normal, it is cut immediately to the manual, if necessary, may be down, down-load operation. Closely monitor the development trend of damaged parts, good accident anticipation, application shutdown as soon as possible. 2, if the leak is serious, the bursting point temperature after a sharp rise in quality work, leading to serious over-temperature wall, unable to maintain the normal operation of the boiler or threaten the safety equipment, emergency shutdown provision should be processed, when the steam temperature to protect the action value, the protection does not move, should immediately hand MFT. 3, note that the operation of the electrostatic precipitator, to strengthen the inspection checks, to prevent fouling, and the electrodes ESP hopper, pipes and the like plugging air preheater ash. 4, after the shutdown, should retain ID fan, the furnace pressure is maintained constant, there is no discharge to be stopped after soda ID fan.
The use of electric steam boilers What are the requirements? General Electric steam boiler is to be converted into an energy form of heat, through the conversion of the boiler can be turned into heat energy of steam or hot water, which requires the use of gas when you have it steam boiler, steam boiler in the first before water is necessary to check each valve, steam pipe, pressure variations, water tables, etc. also note the drain valve is not also intact. after the steam inside the boiler should be kept clean to be used, to which water is after softening the outer glass tube in the water table to be equipped with rugged protective cover, but also to keep it clean after each use it is necessary to scrub, as well as to see the water level of the water table there rise or fall, if it stops phenomenon, we must immediately investigate the cause. after the adjustment is not just above the steam boiler safety valve.
Auxiliary means configuration of the auxiliary boiler apparatus comprising a boiler fuel supply means, air blowing means, the wind means, water supply means, means ash, dust removal device, instrumentation, valves and other automatic control device. Today small to introduce a boiler with auxiliary devices. A boiler fuel supply role is to store, transport, supply of the fuel. There are coal, to the media devices (mill, of mill, and coarse powder separator and lose powder duct), and supply means (for the fuel heater and the like), a gas supply device and the like. Air blowing means which effect a treasure ah blower and duct, the grinding media and air into the furnace through the air preheater apparatus. Blower apparatus, comprising a draft fan and the smokestack, speaking furnace flue gas to exclude air sent. Water supply means comprises a water tank, water supply pipes and water treatment equipment, boiler feed water away. In addition to ash means ash comprising artificial addition, other mechanical ash, ash in addition to water, in addition to the negative pressure pneumatic ash, soot blowers, and other field ash, ash from the boiler and out away. Dust removing device, which includes a variety of dust action of gravity, inertial force, centrifugal force, washing bar-type, sound wave, filtering, static electricity, etc., fly ash out of the boiler flue gas, to protect the environment. Instruments, automatic control devices and valves, including the role of pressure gauge, a thermometer, a water level gauge, the alarm level, the relief valve, water meter, steam flow meter, pressure meter, indicating the exhaust of carbon dioxide and other instruments, a steam valve, a valve, a check valve, like the valve discharge valve, and automatic detection, automatic protection, control and automatic adjustment and automatic computer control means. The boiler more safe, economical operation. These are the auxiliary device structure of the boiler, I believe you must have learned a lot of knowledge of it, I hope this helps you make better use of boiler equipment.
