Description

technical field

[0001] The invention relates to the field of thermal equipment manufacturing, in particular to an energy-saving and environment-friendly boiler tail gas discharge tower. Background technique

[0002] In daily production, gas boilers have a wide range of applications, and are suitable for industrial drying applications, large commercial buildings or heating in civil buildings.

[0003] The general temperature of gas boiler tail gas can reach about 150 ℃, and there is waste heat that can be recycled. At present, there have been researches on waste heat recovery of boiler tail gas at home and abroad, and some products have been produced. Such as figure 1 The schematic diagram of the structure comparison of two kinds of boiler tail gas waste heat devices in the prior art is shown. A is a schematic diagram of a general exhaust gas waste heat recovery device; B is a schematic diagram of exhaust waste heat recovery installed. After the tail gas heat exchanger is i...
