基于热泵技术的燃气锅炉余热回收节能效益分析

Energy-saving Benefit Analysis of Waste Heat Recovery of Gas-fired Boilers Based on Heat Pump Technology

燃气锅炉排放的烟气中水蒸气凝结热的回收具有重要意义。本文对某燃气锅炉烟气余热回收项目进行了工艺方案的设计和主设备选型,测算了相关的技术经济指标。在对关键参数进行敏感性分析的同时评估了节能减排的效益并提出节能效益计量方式的建议。

The recovery of steam condensation heat from gas-fired boilers is of great significance.In this paper, the process scheme is designed and the main equipment is selected in a project of waste heat recovery from gas-fired boiler flue gas. The technical and economical indexes and the sensitivity analysis of the key parameters are calculated,and the benefit of energy saving and emission reduction is evaluated,and measurement the method of measuring energy saving benefit is suggested.
