The combustion chamber and heat exchanger of this hot blast stove are integrated, adopting a multi-layer sleeve structure made of all steel plates. The lower part of the furnace core is the combustion chamber, and the upper and surrounding parts are annular heat exchangers. The air and flue gas are both double return paths, each carrying out heat exchange in its own way. In order to improve thermal efficiency, multi head spiral groove heat transfer technology and turbulent flow principle are adopted to reduce the thickness of laminar flow, so that air and flue gas continuously change their rotation direction during movement, greatly enhancing the heat transfer effect.
The main working process is: light oil (gas) burns in the combustion chamber to produce high-temperature flue gas, which enters the smoke ring under the action of the combustion engine, exchanges heat with the outside air, and is discharged through the chimney through the flue. Cold air is blown into the shell of the hot blast furnace by the blower, flows into the air ring outside the furnace through the top of the furnace, and is supplied to the equipment that needs clean hot air through the hot air outlet pipeline.

a、 Using methanol as fuel.
b、 Using clean hot air as the drying medium, pollution-free.
c、 Low energy consumption and high thermal efficiency.
d、 Automatic temperature measurement and display.
e、 Easy to operate, convenient to use, all supporting equipment (excluding combustion engines) are domestically produced, and their performance indicators have reached the advanced level in China.
