By rotating the coal valve of the coal adding system, the coal valve is opened alternately to allow bituminous coal to enter the furnace from the coal bunker. Air and self-produced steam are mixed in the air inlet pipe at the bottom of the furnace and enter the furnace as a gasification agent to undergo a complex oxidation-reduction reaction with the gas. The generated gas is led out from the top and bottom gas pipes respectively. The emergence of gas generators has solved a major problem of environmental protection for the world. This article will talk about the advantages of two-stage gas generators.

Energy saving:

The amount of air required for complete combustion of coal gas is close to the theoretical amount of air required. The excess air coefficient is 1.05, which is less than burning oil or coal. It is easy to adjust the flame and reduce the heat loss caused by incomplete combustion. As the amount of excess air is reduced, the amount of waste flue gas is reduced, and the heat loss brought by the waste flue gas will also be reduced, thereby improving the heat utilization rate of the entire equipment.

Environmental friendly:

The coal gas production technology of the gas generator strictly controls the fly ash and other pollutants entering the atmosphere through the processes of dust removal, water washing, and decoking of the gas. Due to the reasonable combustion process, less harmful waste gas is generated. The waste water is recycled in the gas station and is basically not discharged outside;

economy: 

Under normal circumstances, using generator gas saves about 5% compared to direct coal burning. At the same time, the double-stage gas generator can also refine coal tar and sell it as a by-product. Each ton of coal can generally refine 50 kilograms of coal tar. The price of coal tar per kilogram is 2 yuan, which is equivalent to a 100 yuan price drop per ton of coal; 

convenient: 

The two-stage gas generator can adjust the temperature in the kiln by increasing or decreasing the number of burners and changing their positions, thereby improving the first-grade rate of fired products. In particular, the cold gas can also heat and bake relatively clean products due to its high purity. 

widely: 

Two-stage gas generators play a very important role in many fields, such as machinery manufacturing, metallurgy and smelting, construction and building materials, as well as chemical and light industry. With the development of science and technology, coal gas has become a gas that needs to be used in many places. It plays a very important role in our lives and plays a role that cannot be ignored in the development of our economy.
