Description

Technical Field

[0002] The low-temperature economizer is installed in the boiler tail flue and connected to the low-pressure section of the turbine's regenerative system. Its core working principle is to utilize the waste heat in the flue gas to heat condensate or other media, thereby recovering heat energy and reducing the exhaust gas temperature. Specifically, condensate is drawn from a suitable location, in whole or in part, and sent to the low-temperature economizer to absorb exhaust heat. After being heated and its temperature increased, the condensate is then transferred through a heat exchanger (such as a plate-and-shell heat exchanger) to heat boiler feedwater (in summer) or heating network water (in winter).

[0003] Existing equipment is inconvenient to fix and disassemble during use, and it is not convenient to protect the equipment when it is subjected to external impact. At the same time, it is not convenient to detect and alert staff when the heat exchanger leaks, and it is not convenient to provide convenience for staff to operate at night. Therefore, we propose a low-temperature economizer flue gas heat exchange device. Utility Model Content
