Energy-saving boilers are also called waste heat boilers.

Energy-saving boilers are also called waste heat boilers. As the name implies, they refer to boilers that use the waste heat in various industrial processes, waste gas or waste liquid and the heat generated by the combustion of combustible substances to heat water to a certain working fluid. Oil-fired boilers, gas-fired boilers, and coal-fired boilers with waste heat recovery and utilization of smoke boxes and flues are also called waste heat boilers. Waste heat boilers can produce hot water or steam for use in other sections through waste heat recovery.Vacuum heat treatment of slender hollow parts principle Fuel, gas, and coal are burned to generate high-temperature flue gas to release heat. The high-temperature flue gas first enters the furnace, then enters the waste heat recovery device of the front smoke box, then enters the pyrotechnic pipe, and finally enters the waste heat recovery device in the flue of the rear smoke box. The flue gas becomes low-temperature flue gas and is discharged into the atmosphere through the chimney. Because the waste heat boiler greatly improves the utilization rate of the heat released by fuel combustion, this kind of boiler is very energy-saving. Due to the complex manufacturing process of waste heat boilers, the production cost is relatively high, so the boilers are expensive.Vacuum gas Quenching of 45CrNiMo1VA Steel Spinning Mandrel composition Oil-fired gas-fired energy-saving boilers are mainly composed of burners, controllers, power distribution boxes, furnaces, pyrotechnic pipes, front and rear smoke boxes (internal replacement hot water jackets), flues and chimneys; coal-fired energy-saving boilers are mainly composed of furnaces, water and fire pipes, overheating It consists of evaporator, evaporator, economizer, front and rear smoke boxes, flue and chimney.Vacuum quenching of KMN steel structure
