摘要
对某公司原余热回收方案进行节能改造,将焊接板式换热器作为余热回收设备应用于某公司的余热回收系统中,完成对该回收系统的节能改造,该系统烟气经过第一级换热器温度为350℃,经过节能改造之后,烟气温度降到150℃。每天可回收热量202.2k W,每台余热回收设备每年可以节约178.81吨的标煤,节能潜力巨大。
Improve a firm＇s original plan for energy saving, the all -welded plate heat exchangers are used in the company＇s waste heat recovery system and complete the energy - saving recovery system. The temperature of the flue through the first stage heat exchanger is 350℃, and after energy - saving, the temperature of flue gas is down to 150℃. It can recover 202. 2kW per day. Every waste heat recovery equipment can save 178.81 tons of standard coal. The potential of energy - saving is enormous.
