500kg h automatic gas steam boiler china

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.

Classification and distinction and design a gas boiler, gas boiler gas boiler classified in accordance with the fuel can be divided into natural gas boilers, boiler city gas, coke oven gas boiler, liquefied petroleum gas boilers and gas boilers; according to the function can be divided into gas boiler water , gas hot water boiler (gas heating boiler comprising a boiler and bath gas), gas 500kg h automatic steam boiler china and the like; can be divided according to the structure of vertical gas boiler, gas boiler horizontal; in accordance with the process can be divided into a single flue gas boiler and tris backhaul backhaul gas-fired boiler. Second, the difference between fuel oil-fired boiler fuel boilers and gas boilers is fuel (such as diesel, oil, kerosene, etc.), fuel gas-fired boiler to gas (such as natural gas, city gas, biogas as well as liquefied petroleum gas, etc.), depending on the boiler What fuel burning device called a burner, boiler gas burner configuration called gas-fired boiler, oil boiler burner configuration called oil-fired boiler, oil-fired boiler and gas boiler difference is that what fuel burners. Third, the design of the boiler furnace by the gas boiler structural design pressure, provided through the top of the large pores, the boiler operates at atmospheric pressure, away from the danger of explosion; boiler furnace using computer simulation to optimize the design, the size of the boiler is fully optimized, so that coordination and beautiful form. Vertical-mounted boiler combustion at the burner, combustion of the fuel within the positive pressure furnace, baffle interposed smoke tube, slow smoke evacuation rate, to strengthen the heat exchanger, the heat furnace to ensure maximize fuel combustion water, improving the thermal efficiency of the boiler; horizontal wet back boiler full three pass structure, the length of the flue gas flow, reducing exhaust gas temperature, the whole corrugated furnace provided, so that the flame produced a strong turbulence to improve the heat transfer coefficient strength, and effectively It is prevented due to thermal expansion and contraction of metal results in a reduction of the life of the device; smoke tubes of large diameter and large pore bridge the gap, the boiler at equal time scale coating thin and easy to clean.

When the external inspection of the 500kg h automatic steam boiler china few notes below Henan fast boiler's steam boiler Xiao Bian told you about the external examination of the few notes need to be transported when the steam boiler, it is necessary to check the external steam boiler, 1, security accessories are complete, sensitive, reliable, secure attachment of the installation for compliance with relevant regulatory requirements. 2, can test gauge when necessary, the safety valve exhaust test. 3, auxiliary equipment (fans, pumps) is functioning properly. 4, automatic control equipment, signal systems and a variety of instruments is sensitive and reliable. 5, various types of door is tight, leaks and corrosion. 6, placed in the drum to the combustion chamber wall may be observed, water wall is normal, without deformation or other anomalies. 7, the combustion is stable, whether black smoke chimney. 8, steam boiler furnace wall, architecture, platforms, escalators, etc. is intact: water treatment equipment is operating properly. 9, boiler room facilities for compliance with relevant regulatory requirements, management is normal and so on. 10, the visible parts of the boiler weld cracks cracks (joints) appears. Classification of a steam boiler combustion apparatus, the four-way steam boilers for solid fuel burner layer being layered on the furnace grate stratified charge combustion. Such as: hand-burning stove, chain furnace stoker furnace. Second, the four-way chamber burner fuel mist of fine particles with the air injected into the furnace combustion furnace in suspension. Such as: Pulverized Coal, oil furnace, gas furnace or the like. Three, four boiling furnace fuel stream is lifted carrying like rolling boil under goes a combustion furnace.

Fast boiler is a research and development, production and sales of high-tech enterprises, adhering to the "do professional, responsible for cleaning boiler systems integration provider" business philosophy, creating a series of excellent quality boiler equipment, such as WNS series gas (oil) boiler, SZS series of gas (oil) boilers, electric boilers and so on; second to none in the area of ​​the National clean boiler. But we never had stalled the pace of independent research in recent years, the introduction of movable type boiler, after obtaining a favorable investment market.
