Hello everyone~The return air furnace and gasifier are two common boiler equipment, then what is the difference between them, today I will explain in detail for you. Let everyone in the choice of boiler equipment more accurately according to the actual needs and application scenarios to choose the right equipment, take a look.
1, the principle is different: gasifier belongs to the high temperature and oxygen decomposition of wood or particles to produce combustible gases, and then the resulting gases are transported to the combustion chamber and secondary oxygen mixing combustion, to achieve the purpose of saving fuel. Return furnace is in the combustion chamber directly ignited combustion, and then the unburned flue gas to increase a return, and then burn again.
2, the structure is different: gasifier structure is divided into the gasification part and combustion part. Return furnace structure only a combustion chamber, plus a chimney directly out of the direct burner furnace, through a baffle to isolate the direct channel, so that the flue gas to go a little more, and then excluded from the chimney becomes a return furnace.
The role and principle of gasifier
Gasifier is a kind of furnace that converts solid or liquid fuel into combustible gas. A gasifier works by using high temperatures and a catalyst to heat and break down the fuel to produce a combustible gas. Gasifiers can use a variety of solid or liquid fuels, such as coal, wood, and household waste. The main function of the gasifier is to convert these fuels into combustible gases for use in a variety of industrial combustion machinery. Gasifier is easy to use, high efficiency, high energy utilization, so it is widely used in industrial production.
The role and principle of the return air furnace
The return air furnace is a kind of equipment used to recover the waste heat in the industrial furnace. The working principle of the return air furnace is to introduce the waste gas from the furnace into the return air furnace for heat exchange, and to recover the waste heat and convert it into useful heat energy in the heat exchange process. Through the use of return air furnace, you can recover waste heat from industrial production, save energy and reduce environmental pollution.
