Oil or gas FGR boiler
The energy saving and emission reduction of the boiler has always been the focus of the whole industry. Reduce the smoke from coal-fired boilers at first, to the oil or gas boiler recently to reduce NOx emission. All work for the living environment of human beings. Here we will introduce the Shengli boiler, the ultra low nitrogen oxide emission boiler, the oil or gas FGR boiler.
As we all know, when the oil or gas is burned, pollutants are related to the oxygen content and temperature of the combustion. In order to reduce the emission of pollutants and improve the efficiency of combustion, all the major boiler companies have tried their best. The fuel gas FGR boiler of Shengli boiler has solved this problem from the source. Its core principle is to introduce the low temperature and low oxygen content of boiler tail gas, which is burning in the boiler, and into the furnace according to a certain proportion. As a result, the oxygen content is reduced to make the combustion as sufficient as possible, and the low temperature tail gas can also reduce the temperature in the furnace, and effectively reduce the emission of NOx.
The design of the Shengli Boiler Oil or gas FGR Boiler divides the combustion process into three levels. The main combustion area is sent to most of the fuel, and the air required for fuel combustion is sent into the furnace at a stage, and the amount of air is sent to the main combustion zone by about 80%. The upper part of the main combustion zone (the downstream of the flame) is injected into the two fuel to reburn, and the remaining air is sent to the third zone to complete the burnout process. In order to achieve fuel and air staged combustion.
