The hot blast stove, which is a thermodynamic machine, was widely used in China in the late 1970s. It has become a replacement for electric heat sources and traditional steam-powered heat sources in many industries. There are many varieties and series of hot-blast stoves. They are divided into two types: hand-burning and machine-burning. The types of fuel are divided into coal, oil and gas furnaces.
Through long-term production practices, it has been recognized that the use of hot air as a medium and carrier can greatly improve heat utilization and thermal work. Traditional
The electric heat source and the steam heat power are often arranged with a plurality of circulating fans during the conveying process, so that the hot air is finally formed indirectly for drying or heating operations. This process obviously has a lot of shortcomings such as wasting energy and causing excessive auxiliary equipment and complicated process. The bigger problem is that this heat source is at a loss for the need for higher temperature drying or baking operations. After years of painstaking research on these practical problems, we have finally developed the JDC series spiral finned tube heat exchange indirect hot air furnace and JDC series high purification which are popular among users at home and abroad.
The role of the hot blast furnace in the ironmaking blast furnace is to heat the blast to the required temperature to improve the efficiency and efficiency of the blast furnace; it works according to the principle of "heat storage". The gas is burned in the combustion chamber, and the high-temperature exhaust gas passes through the checker brick to store heat. When the checker brick is fully heated, the hot blast stove can be changed to supply air. At this time, the relevant valves of the combustion are closed, and the air supply valves are opened, and the cold air is turned on. The bricks are heated and sent out. When the blast furnace is equipped with 3-4 hot air stoves, two or three seats are heated, one is supplied with air, and when the water is replaced, the two are heated.
