Through a long time of production practice, people have realized that only using hot air as medium and carrier can greatly improve heat utilization and thermal work effect. The traditional electric heat source and steam thermal power are often equipped with multiple circulating fans in the transmission process, so that it finally forms hot air indirectly for drying or heating operation.

This process obviously has many disadvantages, such as a large waste of energy, too many auxiliary equipment, complex process and so on. The bigger problem is that this heat source is helpless for the requirements that require higher temperature drying or baking operations. In view of these practical problems, after years of painstaking research, Ronghua company has finally developed a gas hot blast stove made of silicon carbide, which is welcomed by users at home and abroad.
The gas-fired hot blast stove made of silicon carbide is a new tubular high-temperature heat recovery device, which can be widely used in metallurgy, machinery, building materials, chemical industry and other industries. It can directly recover the waste heat of 850-1400 ℃ high-temperature flue gas discharged by various industrial kilns to obtain high-temperature combustion supporting air or process gas.
The heat exchange element material of this device is a new type of silicon carbide engineering ceramics. It has excellent properties of high temperature resistance and thermal shock resistance. It is air cooled from 1000 ℃ to room temperature and repeated more than 50 times without cracks; The thermal conductivity is equal to that of stainless steel; It has good corrosion resistance in oxidizing and acidic media. The problem of thermal compensation and gas sealing is successfully solved in structure.
