Meanwhile, the party also fast boiler design automation control systems, temperature, pressure, and other parameters automatically adjust the water level, real-time monitoring anti-smoke temperature, oxygen content and changes in safety interlock, even if unattended, the boiler can function . In mid-January 2019, under the fast boiler joint efforts of all staff, boiler manufacturing is completed, the pipeline project has reached Hwashi ground, and successfully complete the installation and commissioning work. At present, the boiler has been put into the urban underground pipeline construction and maintenance projects in order to contribute to building a better city.
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, 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 .
What are the main parts of the boiler? No matter what kind of equipment, accessories are essential, and parts of the boiler is very much, even the smallest one ton tonnage industrial gas boiler, but also by the composition system accessories, not to mention the large circulating fluidized bed the number of parts of the boiler. Zheng pot boiler accessories is one of the main marketing services provided, as even wear tiny boiler, but also need to replace individual parts within a certain period of time, to ensure safe and stable operation of the boiler.
