Based on the nume
3、rical model, the performance indexes of boiler system are calculated at different conditions using EES (Engineering Equation Software). The results show that when the exhausted gas or inlet air temperature increases 10- 15 , the heat loss of exhaust gas decreases 0.8%-1% and thermal efficiency of bo
4、iler system increases 0.8%-1%. The crucial factors that can affect thermal efficiency are exhaust gas temperature and fuel volatile ratio; seven optimized schemes are designed for a case of boiler system. A new methodology is provided for evaluating the efficiency of boiler system. Keywords: boiler; model reduction; numerical simulation; thermal efficiency; evaluation model; optimal design 1.Introduction Boiler is one of the high energy-consumption equipment to provide hot water/steam for the c
