Coal-fired Air Heater

1. Our coal-fired air heater is easy to operate. The temperature control device will automatically control the temperature as long as you have set the sensing systems in the combustion chamber and your factory or poultry house. All you need to do then is add coal into the combustion chamber.
2. Because the gas flue is controlled by an induced draft fan, the gas flue can heat a room together with the hot air. The total heat use efficiency of our coal-fired air heater is as high as 95%.
3. This coal-fired heater is specially designed with a secondary heating function and can heat a room quickly with clean air.
4. A specially manufactured cast steel tubing system that is durable and heat resistant is used in the combustion chamber.
5. Two hot air ducts allow the clean hot air to flow from their top end to the terminal end to heat a room evenly.
6. The coal-fired heater we offer is equipped with two forced draft fans. In case one breaks, the other ensures the air heating system continues to work normally.

Our coal-fired air heater has the capacity to heat up to 1200 square meters and is widely used for the following applications:
1. Warming of agricultural greenhouses, livestock, and poultry houses
2. Drying and dehumidification of small to medium sized enterprise workshops for papermaking, pharmaceutical, grain processing, and silk industries.
3. Ventilation and drying of mines and other underground engineering.
