Heat Economic Analysis of Drainage Recycling Mode in Thermal System
Thermal system drainage recycling mode has a great influence on heat economy of a power unit.Drainage cooler can be used to decrease the temperature to recycle drainage heat and drainage pump which can intercept drainage to approach the effect of extraction heat utilizing of combined heater.The heat efficiency of different modes of drainage recycling is calculated and analyzed with heat balance method and equivalent enthalpy drop method in this paper,which provides the quantitative date for thermal system energy saving and transformation.And on the basis of heat balance method,the calculating inaccuracy of equivalent enthalpy drop method is analyzed.
Knowing the feasibility of the business of an enterprise is a consideration in starting a business. The purpose of this study was to determine whether there is any possibility of business development based on investment proposals Laundry The Blues.
