BHN type edge opening gas electric heating furnace

BH-BHN series gas electric heating furnace. Based on the various heating electric furnace products used in the conversion process of sulfuric acid plants in China and their usage, Biaohua Company has organized a technical research and development team led by senior electrical engineers. Based on our company's years of experience in producing resistance furnaces, we have developed and produced a new generation of electric furnace products with a new structure. The electric furnace product has a reasonable design, reliable operation, durability, and no feedback on air leakage, making maintenance labor-saving and time-saving. This research achievement has been widely adopted in the equipment production process renovation project of Huludao Zinc Industry Group, an old industrial base in Northeast China, and has received unanimous recognition and praise from senior national researchers.

Main Performance Characteristics
This utility model belongs to the category of mechanical engineering electric heating, which is an electric heating furnace for heating gas preheating and conversion system of sulfuric acid device. It can also be used for heating and warming other non flammable and explosive gases. Its feature is that the electric heating element assembly in the furnace can be moved out of the furnace through the inspection door on the side of the trolley wheel and track, which is convenient for maintenance and reduces labor intensity. The heat-resistant insulators in the electric heating element assembly are horizontally placed and fixed on the frame perpendicular to the airflow direction. The electric heating wire is wound in a straight line between each pair of two heat-resistant insulators, and the vast majority of the electric heating wire is exposed in space, which is convenient for thermal radiation. The thermal efficiency is high, the surface temperature of the electric heating wire is low, and the service life can be extended. The specific characteristics are as follows:

Long lifespan: The new resistance wire winding method exposes over 95% of the surface of the electric heating element to the airflow, resulting in a high heat transfer coefficient. In addition, the designed electric wire has a low surface load, making it less prone to breakage;
◆ Easy replacement of components. Side door opening structure, fast and effortless;
◆ Lightweight: Only one-third the weight of a grid shaped electric furnace of the same power, lightweight internal insulation, and stainless steel inner liner with good corrosion resistance;
◆ Uniform spatial temperature distribution: Even when any set of electric heating elements is disabled, the heated gas can still be uniformly heated;
◆ Energy saving and fast heating: More than 95% of the electric heating element surface is in contact with the current flow, directly transferring heat without the disadvantages of local shielding or mutual interference of electric heating wires, resulting in high thermal efficiency;
Low resistance: basically equivalent to the resistance of pipelines.
