Introduction

鍋爐用冷凝器，又稱煙氣冷凝器 ，鍋爐使用煙氣冷凝器后，可有效節(jié)約生產(chǎn)成本，降低鍋爐的排煙溫度，提高鍋爐熱效率，使鍋爐運行符合國家節(jié)能減排標(biāo)準(zhǔn)。

Boiler condenser, also known as flue gas condenser, can effectively save production costs, reduce the flue gas temperature of the boiler, improve the thermal efficiency of the boiler, so that the boiler could meet the national energy saving and emission reduction standards.

This kind of equipment is suitable for oil-fired and gas-fired boilers.
