| Abstract: | Taking the theory of small disturbance as the basis,and based on the basic equation of thermal economic efficiency in the thermodynamic system,a commonly used simple and easy calculation model has been deducted for the influence of heater's terminal temperature difference upon the coal consumption of unit under comstant flow rate condition.Taking a 1000 MW unit as example,the calculated result has been analysed,it shows that the said model can accurately and rapidly evaluate the influence of terminal temper... |
