Guide: With the accelerated implementation of my country's West-East Gas Transmission Project and other natural gas projects, it can be expected that the application of natural gas in industrial boilers will have a relatively large development. The content of water vapor in the flue gas produced by the combustion of natural gas is much higher than that of other fuels.
With the accelerated implementation of my country's West-East Gas Transmission Project and other natural gas projects, it can be expected that the application of natural gas in industrial boilers will have a relatively large development. The content of water vapor in the flue gas produced by the combustion of natural gas is much higher than that of other fuels. When water vapor condenses, a large amount of heat is released, which is the release of latent heat of vaporization. The condensing boiler takes advantage of this characteristic of natural gas, and applies the principle of condensing heat transfer to the heat transfer of the heating surface at the tail of the boiler to maximize the utilization rate of heat energy.
The separation system of the circulating fluidized boiler is composed of a high-temperature cyclone separator, a fly ash return device or an external low-speed fluidized bed heat exchanger. Xinli circulating fluidized bed boiler is divided into SHX and DHX series, both of which retain the technical advantages of circulating fluidized bed low-temperature combustion, adjust the ratio of primary and secondary air supply, optimize the layout of secondary air, and rationally design the furnace heating surface , Control the bed temperature at 860~880℃, effectively control the emission of NOx. Compared with other environmentally friendly boilers that reduce NOx emissions through burners, circulating fluidized beds fundamentally solve the problem of excessive NOx concentration. At the same time, in order to reduce the operating cost of the company’s boilers, Xinli’s technical staff also adopted a low air chamber air pressure design, reduced the proportion of primary air, adjusted the resistance of the air distribution board, and selected the appropriate primary and secondary fan motor powers to effectively reduce plant power consumption. The self-consumption of the new circulating fluidized bed boiler produced is reduced by about 20-30%.
Boiler energy saving is a technology. It can improve the thermal efficiency of the boiler, can make the thermal efficiency of the boiler reach a higher level, and can save coal by 10%-15%. Boiler energy saving is the automatic control of induced draft fans, blowers, grate, water pumps and other departments in the boiler equipment through the boiler information energy-saving control system, so as to achieve the effect of improving the thermal efficiency of the boiler.
For a long time, Sony Boiler has contributed its own strength in improving economic, environmental and social benefits. In the future, Xinli Boiler will join hands with more companies to carry out more in-depth and friendly cooperation to jointly make the urban living environment more comfortable, and at the same time contribute to the sustainable development of the earth, how to install the boiler pressure control.
