What is the principle of boiler waste heat recovery?
The boiler is a kind of energy conversion equipment. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator.
If the exhaust gas temperature of the boiler is too high, the thermal efficiency of the boiler will be low, and the flue gas will bring a lot of heat into the atmosphere, which not only wastes a lot of energy, but also pollutes the environment. If, through the modification of the heating surface at the tail of the boiler, the expansion of the heating surface is used to increase the heat exchange area and enhance the heat exchange effect, so as to achieve the effect of reducing the exhaust gas temperature and realize energy saving and emission reduction. Boiler exhaust gas temperature is generally 130 ~ 140 degrees Celsius.
The steam radiator quickly evaporates the water content of the object through the circulation of hot air, which conforms to the two characteristics of physical laws: the same temperature, the faster the evaporation in the case of wind, and the higher the temperature under the influence of the same wind force , evaporates faster. The hot air circulation oven uses this principle to convert electricity into a heat source, and uses a low-noise, high-temperature-resistant flow fan.
