What are the schemes for boiler flue gas waste heat recovery?

I recommend a boiler flue gas waste heat recovery scheme for you. Industrial boiler is the main thermal equipment in China. With the rapid development of economy in recent years, the problem of energy consumption has become increasingly apparent, and energy conservation and waste heat recovery have entered the public's field of vision. Today we will introduce a kind of heat recovery and reuse equipment, boiler flue gas waste heat recovery device. Let's first understand what kind of equipment it is and what its characteristics are. First, the status quo of waste heat recovery The traditional thermal energy resources such as coal, electricity, petroleum and natural gas are limited, and there are widespread problems in industrial production, such as low thermal energy utilization efficiency, high exhaust heat temperature and complex components. Direct discharge will cause air pollution to the environment.

On the one hand, the energy consumption of thermal power is too high, on the other hand, the waste of pollutants and high-temperature flue gas also causes a lot of energy losses. Two. Types of boiler waste heat recovery device This device is mainly used for heat recovery of flue gas discharged from boilers, and most of them are suitable for coal-fired, oil-fired and gas-fired boilers. Its main function is to help reduce the flue gas temperature of the boiler, recover the residual heat contained in the flue gas for secondary utilization, and increase the feed water temperature for heating or other purposes. Generally speaking, there are many commonly used waste heat recovery devices, such as tubular and rotary. Plate equipment is widely used in large-scale boiler preheating and recovery project, because it is composed of a single module and can be used at will.

Three. Advantages and characteristics The advantages of the boiler flue gas waste heat recovery device are that there are many types of equipment, which can meet the waste heat recovery of high, medium and low flue gas temperatures, and the total pressure drop of the internal structure is small, the required power is reduced, the structure is reasonable and compact, and the occupied area is smaller and more beautiful. The heat exchange surface in contact with flue gas has good corrosion resistance, pressure bearing capacity and operational stability.
