Judging from the current relevant policies in my country, the requirements for pollutant emissions in various provinces and cities in the future will become more and more stringent, and the emissions of nitrogen oxides in natural gas boilers will also be reduced through technical means to meet environmental protection requirements. So how do boiler manufacturers reduce the combustion temperature of natural gas boilers through technical means, so as to achieve environmental protection standards? Let Zhengzhou Fangkuai Boiler Factory come to elaborate for you.
(1) The mixing method of natural gas and air (pre-mixing or diffusion combustion, air segmentation method, primary and secondary air ratio and total excess air coefficient).
(2) Whether the air is preheated and the preheating temperature.
(3) The layout of the heating surface in the furnace.
Modern large boilers are designed with low nitrogen emissions to avoid the simultaneous occurrence of high oxygen concentration and high temperature in the same area. Therefore, it can be assumed that the boiler adopts air segmented combustion, and the primary air and fuel are premixed. But CFD simulation shows that in the center of the flame, the maximum temperature is still between 1600-1900 degrees Celsius. Outside the flame center, the temperature should be quickly reduced to below 1500 degrees Celsius, and the walls and corners should be lower.
