The difference between reverse-fired and direct-fired heating stoves

The differences are: different definitions, different structures and different functions.

1, with different definitions: flame-proof boiler refers to a boiler with two rows of boilers; The combustion device of direct-fired coal-fired hot blast stove is mechanical chain grate or reciprocating grate.

2. Different structure: structurally speaking, it has a water-cooled grate and a fixed grate, and the two grates divide the furnace into three spaces, the upper part, the middle part and the bottom; The direct-fired coal-fired hot blast stove consists of a coal-fired machine, a high-temperature gas purification settling chamber and an air mixing chamber.

3. Different functions: reverse combustion can be used for cooking and heating, which is of great significance to promoting circular economy, building an ecological society and realizing a low-carbon economy, and is the best choice to replace coal burning at present; Direct combustion can not only burn coal, but also use industrial and agricultural wastes as fuel. It is an efficient and energy-saving heat source special for drying system.

Extended data:

Advantages of direct-fired type:

1, coal has wide adaptability; High combustion efficiency, thermal efficiency >: 95%, stable output heat load, mechanical combustion, simple operation and very convenient adjustment.

2, environmental protection standards, no secondary pollution, clean operating environment; The cleanliness of hot air is high, and the dust content is 30 ~ 1.20 mg/nm3.

3. The hot air temperature can be easily adjusted below 1000℃, and the temperature stability of continuously heated air is 5℃; The equipment has strong durability, low operating cost and simple maintenance.
