What are the common sense of waste heat recovery at the tail of industrial boilers

Industrial boilers are not very familiar to everyone, and do not know the working principle of industrial boilers and work precautions. Today, we will give you relevant answers to the common sense of waste heat recovery at the tail of industrial boilers.

Waste heat is the energy that is not used in energy utilization equipment under certain economic and technical conditions, including high-temperature waste heat, cooling medium waste heat, waste steam waste heat, high-temperature products and slag waste heat, chemical reaction waste heat, combustible waste gas waste liquid and waste. There are seven types of residual heat and high-pressure fluid residual pressure.
According to the survey, the total waste heat resources of various industries account for about 17%~67% of the total fuel consumption, and the recyclable waste heat resources are about 60% of the total waste heat resources. The
super heat pipe is the main heat conduction element of the heat pipe waste heat recovery device. , which is fundamentally different from ordinary heat exchangers.The heat exchange efficiency of the heat pipe waste heat recovery device can reach more than 98%, which cannot be achieved by any ordinary heat exchanger.The heat pipe waste heat recovery device is small in size, only the ordinary heat exchanger 13.
Under the action of the blower, the clean air at room temperature flows in the opposite direction along the right channel to flush the heat pipe. At this time, the heat pipe releases heat on the right side, heating the clean air, and the temperature after the air flows through the heat pipe rise.
The waste heat recovery device composed of several heat pipes is installed at the boiler flue port, which absorbs the heat in the flue gas and conducts it to the other end at a high speed, so that the exhaust gas temperature is reduced to close to the dew point and the heat emission loss is reduced.The heated clean air can be used to dry materials or be added to the boiler for recycling.Improve the thermal efficiency of boilers and industrial furnaces, reduce fuel consumption, and achieve the purpose of energy saving.Hope this knowledge can help you.
