Problems solved by technology

[0002] A hot blast stove is a device that uses the heat released by fuel combustion to indirectly heat the air and output hot air. It is widely used in grain drying and other fields. The existing larger hot blast stoves generally use tube-and-tube heat exchangers. Structural limitations make the unit heat exchange efficiency low so that the heat exchanger has a large volume, coupled with the connection method with the combustion furnace body, etc., it occupies a large area and is difficult to construct and maintain; small hot blast stoves also use plate heat exchange The heat exchanger is used as a heat exchange device, but the exchanging heat of the existing plate heat exchange hot blast stove is very small, because the heat exchange area between the cold air and the hot flue gas is small, and its heat exchange efficiency is very low, thereby reducing the utilization rate of energy
