Industry Fuel Pressure Fire Tube Boiler

Industry Fuel Pressure Fire Tube Boiler

Internal and external inspection of in-service pressure-bearing equipment: In order to ensure the normal and safe operation of the power plant industry fuel pressure fire tube boiler, it is necessary to carry out the necessary inspection according to the legal norms and standards, and to carry out the comprehensive inspection of the pressure-bearing equipment on a regular basis. Conduct inspection in accordance with the relevant provisions of the regular Inspection rules for boilers. Periodic inspection cycle is divided into external inspection, internal inspection and pressure test. And each inspection time has the clear stipulation. In the "rules for regular Inspection of boilers", there are clear regulations and requirements in terms of inspection preparation, inspection methods, inspection contents, treatment of defects and inspection results, so as to avoid omissions and misjudgments in the inspection process. It can effectively improve the performance of the pressure-bearing equipment in the process of operation. Safety and stability.

Minimum air amount and the relationship between the excess air coefficient in the dew point of the flue gas for complete combustion of the fuel required under ideal conditions, said theoretical combustion air amount, the fuel for complete combustion in the actual conditions of incomplete combustion, or the actual amount of air required amount of combustion air . Excess air coefficient = actual combustion air amount / theoretical combustion air amount. Dew point (Dewpoint), also known as the dew point temperature (Dewpointtemperature), in meteorology fixing means under pressure, gaseous water contained in the air is condensed into liquid water saturation dropped to desired temperature. At this temperature, condensed water mist floating in the air is called, while the stick is called on a solid surface exposed, hence the name dew point. Excess air and flue gas dew point relationship when there is insufficient combustion air ratio of the fuel is not sufficiently low combustion efficiency, industry fuel pressure fire tube boiler efficiency is also reduced. When the excess air, the flue gas water vapor partial pressure decreases, the dew point temperature is low, it can not lead to condensation, latent heat can not be released, and the excess air factor will take a lot of heat, so that the boiler efficiency decreases. Therefore, when an excess air ratio of 1.2 to 1.3, to achieve complete combustion in the excess air coefficient is very small, almost chemically incomplete combustion phenomenon. When the air excess factor is 1.2-1.3, both to ensure that the dew point will not be too low (the condensation effect is very significant), but will not take away the excess air ratio in the flue gas waste heat large, which can greatly enhance the thermal efficiency of the boiler .

Should be chosen from the source of nitrogen oxides generated by a industry fuel pressure fire tube boiler control, currently available technology is the use of the most advanced technology gas premix combustion boiler, which can accurately adjust the air-fuel ratio, nitrogen oxide generated from the source control. 2, replacement of the burner

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 industry fuel pressure fire tube 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 steam boiler to natural gas as raw material. After a series of market research, WNS Series Split hospital condensing gas boiler boiler other fast soft spot.
