The waste heat boiler can use the waste heat of high-temperature flue gas, chemical reaction, combustible gas and high-temperature materials to produce high-pressure, medium pressure, low-pressure steam or hot water for process flow or heat supply in the heat supply network. There is no combustion process in the waste heat boiler, which is essentially just a heat exchanger of flue gas water or flue gas steam. In practical application, most waste heat boilers use 350~800 ℃ high-temperature flue gas, which is a low-temperature boiler compared with the operating temperature of coal-fired boilers. Nearly 80% of flue gas waste heat in metallurgical industry is recovered by waste heat boiler. Do you know the process requirements of waste heat boiler? next, Henan horizontal waste heat boiler supplier Let's have a look!
Due to the complexity of the working environment of waste heat boiler, it has some special requirements for its internal structural parts. In the process of designing and manufacturing the waste heat boiler, the process designer should consider the advantages and disadvantages of various processes, and then select a reasonable process to complete the manufacturing of the waste heat boiler. For example, the serpentine parts in the waste heat boiler cannot be bent automatically by the machine, so they can only be bent manually.
Henan horizontal Waste heat boiler supplier It indicates that the main components of the waste heat boiler can be divided into drum, pipe, header, membrane wall, tube panel, tube box, etc. These components are those with specific process requirements in the waste heat boiler. For example, the drum should go through metal flaw detection, heat treatment, hydrostatic test and other processes, so as to improve the stability of the waste heat boiler. At the same time, due to the high tightness of the header, manual welding is required, and the welding quality needs to be tested.
That's all for the above summary. If we have other questions that we don't understand, please call our company, Henan horizontal waste heat boiler supplier We will serve you patiently!
