Decreasing the turbine exhaust pressure increases the net work per cycle but also decreses the vapor quality of outlet steam. The case of the decrease in the average temperature at which energy is rejected, requires a decrease in the pressure inside condenser (i.e. the decrease in the saturation temperature).The lowest feasible condenser pressure is the saturation pressure corresponding to the

Thermal efficiency is an important index to evaluate boiler performance. Fig. 12 shows that the thermal efficiency decreases with the increase of excess air rate of two types of burners. The experimental condition is that inlet water temperature is 30 °C, cooling water flow is 15 L/min, the heat load is 24 kW.
