What is the difference between gas-fired hot blast stove and coal-fired hot blast stove? The gas-fired hot blast stove is clean, extinguished sufficiently, free of pollutants, and does not need desulfurization and denitration. It has high automation level, safe and reliable, and does not need manual intervention. The cost of one post is less than that of a coal-fired stove. Now coal is in short supply.

   Some manufacturers can't buy coal and don't understand the price. The gas-fired hot blast stove can also save coal transportation and slag. Another important point is that the hot blast stove for extinguishing natural gas can be of direct extinguishing type, which can be directly mixed with air in the extinguishing room.

   The heat exchange efficiency is high, and the heat application rate is close to 100% Simple temperature control, automatic conditioning, temperature up and down 1 degree. (even if today's food is dry, it is directly extinguished). If the hot air is required to be clean, the coal-fired hot blast stove must adopt indirect heat exchange type.

   Low heat exchange efficiency, difficult temperature control and large heat loss. Specially assigned person is responsible for coal demand, and the furnace temperature fluctuates greatly. Gas extinguishing has the advantages of fast heating, stable furnace temperature, no slag and environmental protection.
