Heat Exchanger Hot Blast Stove

The heat exchange hot blast stove is mainly composed of MBL burner, high temperature gas purification chamber, heat exchanger, auxiliary equipment and control. The countercurrent gas phase heat exchange is adopted, the high temperature flue gas is outside the heat exchanger tube, and the air is inside the tube. After the heat exchange, the flue gas is partially reused and partially discharged by the flue gas induced draft fan, and the normal temperature air is sent into the heat exchanger through the blower. The burner adopts the chain grate type, and the combustion is stable and complete. A high-temperature dust removal and purification device is installed in front of the heat exchanger to control the dust content entering the heat exchanger and reduce dust accumulation and wear of the heat exchanger. The fuel can be coal and biomass fuel. The heat supply is 25-20 million kcal/hour. The heating temperature range is 50℃～600℃.

Technical characteristics:

(1) Adopt flue gas dust removal and purification technology to effectively control the local burning of the heat exchange tube by the flame, reduce the dust content entering the heat exchanger, and improve the life and thermal efficiency of the heat exchanger;

(2) The heat exchange adopts the countercurrent method, the flue gas goes outside the pipe, and the air goes inside the pipe, which strengthens the heat transfer;

(3) The heat exchange tube adopts advanced jet flow and insert structure, which improves the heat transfer efficiency;

(4) Thermal efficiency > 75%. The maximum output temperature is 600°C, and the temperature stability of hot air is ±5°C;

(5) Long equipment life and low maintenance rate;

(6) The equipment is easy to operate and easy to maintain. High safety, no explosion hazard.

Scope of application:

Food, medicine, chemical industry, building materials, etc.
