Gas Steam Boiler non-normal stall, a phenomenon and treatment, flame reasons: 1, the operation of the auxiliary power supply or trip interruption. 2, boiler combustion instability. 3, the load is too low, so that the load sharply mill automatic ignition energy loss or failure of combustion. 4, mutant coal, coal volatile or low calorific value. 5, the automatic combustion flame detector failure or failure caused by tripping mill. 6, or blast furnace wall tubes serious improper boiler soot-blowing operation, a large amount of water vapor into the combustion chamber. 7, coal pulverizing system, fuel system failure, resulting in a significant amount of fuel reduction or interruption. Or with a large amount of water in the fuel oil gun blocked too many impurities, low pressure steam or atomized. Second, the phenomenon: 1, a significant increase in furnace pressure, furnace flame monitoring flameless CRT display. See the fire no fire hole, BTG warning window MFT warning lights. 2, the unit load decrease, the steam flow drops rapidly, each segment working medium temperature, the vapor pressure decreases, the value of oxygen surge. Third, the method of treatment: 1, if the MFT tripping protection, should an emergency shutdown processing, stop the supply of fuel. 2, identify the cause flameout, and try to eliminate, to conduct a comprehensive inspection of the boiler, after confirming the device properly, can restart.
The third reason is that the amount of nitrogen oxide released during operation is very small. Most heating equipment such as ordinary boilers need to use coal materials as raw materials when they are in operation. Materials such as coal generally release a large amount of hazardous air-quality substances when burned. The condensing boiler uses the steam produced by natural gas combustion as the raw material when it is in operation, so the nitrogen oxide content released during the operation is much lower than the prescribed standard. The analysis of the reason for the year-by-year increase in the sales of condensing boilers has come to an end for the time being.
Food is food industry is human life industry, but also an ancient and eternal evergreen industry. Industrial 8 t/h coal fired steam boiler for textile factory as an integral part of the chain, is mainly used for processing of distillation, extraction, sterilizing, drying, curing and other processes. Anqing City, Anhui Province is located in the Want Want Foods Co., Ltd. mainly engaged in all kinds of puffed food processing and manufacturing and sale of steam boiler steam delivered directly or indirectly in contact with food, thus requiring the steam quality is very high. Due to expanding production needs, Want Want Foods in urgent need of a boiler plant to provide high-quality steam. After a comprehensive understanding of the boiler industry, determined to cooperate with the fast boiler. Want fast square perennial cooperation with the country's food company, it has considerable experience of cooperation. By understanding the needs of the Want Want food production, providing a whole 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
A number of national influence energy consumption 8 t/h coal fired steam boiler for textile factory coal to natural gas has been vigorous work, it should be transported steam boiler, very big eliminate the dust pollution, discharge of toxic gases and secondly nitric oxide, also got curb. Energy consumption is crucial mark measuring steam boiler, a good start and that is that work together to explore under the influence of a number of cases the energy consumption of steam boilers. Through the investigation of the persons concerned, the loss of heat from steam boilers bear the main two areas: combustion air-fuel ratio does not smoke emissions standards-related heat loss. Reduction of heat loss will install smoke emission in the flue gas heat recovery steam boiler terminal fitting, or should be transported more leading type condensation recovery boiler. Combustion air-fuel ratio standard fault summary: a conventional steam boiler burner ejector type, formed air-fuel ratio can not occur motorized adjustment. Some of the steam boiler with a mechanical blower burner, causing air-fuel ratio standard there are several aspects later: the main air-fuel ratio standard case encompass fall into two categories: air flow when exceeded, there will be an endless excess cold heat transfer, resulting in high energy cost of steam boilers, steam boilers reduced energy consumption; when the airflow is not enough, will have not exactly lit, the energy consumption caused by steam boiler weakened.
