Talk about the main design principles and functions of the waste heat boiler

　　The waste heat boiler can be designed according to the site conditions. It is mainly composed of three parts: heat pipe soft water heater, heat pipe boiler, and heat pipe economizer. The heat pipe is arranged in a longitudinal fin and a circular fin fork row. Through the heat pipe, the flue gas and the water complete the heat transfer, and the saturated steam is generated. The structure of the waste heat boiler is not easy to accumulate dust.

　　Because the flue gas of the electric furnace contains a large amount of dust, for example, 6-8kg of dust will be generated when producing 1 ton of steel. Therefore, dust accumulation will occur during the operation of the equipment for a period of time, which will affect the normal operation of the entire system. According to the specific characteristics of the equipment, We use the gas shock wave soot blowing method, equipped with an acetylene station and a gas shock wave soot blowing system. When the resistance of the waste heat boiler system reaches the set value, blow the combustion chamber), where the pre-dust removal and removal are carried out, and the flue gas at 1200°C enters The water-cooled flue is further cooled to 850°C and enters the heat pipe water softener, where the 20°C soft water is heated to 104°C and enters the thermal deaerator. After the flue gas is further cooled, it enters the equipment to produce high-pressure saturated steam. The flue gas enters the heat pipe economizer, and the deoxygenated soft water is heated from 104°C to 200°C and enters the vapor-liquid separator (steam drum). The flue gas drops to 200°C and enters the bag dust removal system.
