Directing against state of affairs at present, such as margin of type - selection parameters being selected comparatively large during design stage of air fans for boilers in thermal power plants, the opening degree of air fans in operation being often smaller ( for adjustment of inlet regulator ) or operation at lower revolution speed ( for speed - regulating operation mode ), and efficiency of air fans being lower etc., factors and corresponding measures having to pay attention in margin selection of air fan ' s parameters have been put forward through analysing practical example of retrofitting forced draft fans in one power plant, playing certain positive role for energy - saving and benefit - increasing in power plants
摘要針對目前火力發電廠鍋爐風機在設計選型時參數裕量選取較大,運行時風門開度較小(對入口調節器調節)或低轉速運行(調速運行方式) ,風機效率較低的狀況,通過對某電廠送風機改造實例的分析,提出了在風機參數選擇中的裕量選取需要注意的因素及相關對策,對電廠的節能增效有一定的積極作用。 -
The air inlet noise is one of the major aerodynamic noises of the diesel generator as a result of the pressure fluctuation caused by the periodic opening and closing of the inlet valve
