摘要
固体废物资源化可对能源进行有效回收和综合利用,并使无用固废实现减量化和无害化的目的,这样不但可提升生活效益,取得良好的经济效益,同时达到了环保的目的,我国固体废物的资源化利用具有广阔前景的开发领域。
The recovery of waste heat irom gas in natural gas boiler can significantly improve the thermal efficiency of the boiler and save energy and reduce the emission. In this paper, the flue gas of natural gas boiler is analyzed, and the thermal efficiency of different flue gas discharge temperatures is calculated. It is pointed out that the dew point temperature of flue gas will decrease with the increase of excess air coefficient, and the thermal efficiency will increase rapidly when the flue gas emission temperature is below 60. The waste heat recovery technology of com-mon condensing and heat pipe type natural gas boiler is studied and its advantages and disadvantages are analyzed.
