Description

Technical Field

[0001] The present invention relates to the technical field of boiler supporting equipment, and in particular to a temperature-controllable low-temperature economizer. Background Art

[0002] An economizer is a device installed at the lower part of the flue at the rear of the boiler to recover the waste heat of the exhaust gas. It heats the boiler feed water into a heating surface of saturated water under drum pressure. Because it absorbs the heat of high-temperature flue gas, it reduces the exhaust temperature of the flue gas, saves energy and improves efficiency, so it is called an economizer.

[0003] When the existing economizer is in use, the flue gas flows along the exhaust channel, causing the heat recovery plate to be heated to heat the boiler feed water. Since the plate is easily adhered to a lot of dust when it is in contact with the flue gas for a long time, if it is not treated, it is easy to reduce the plate's absorption of heat in the flue gas, thereby failing to effectively reduce the exhaust temperature, resulting in serious impact on the economizer's function.
