An approach to the problems in energy-saving generation dispatching

such as coal consumption and pollutants total emission calculation

analysis of uncertainty

and formulation of coal consumption curve etc.

has been made

and the uncertainty in calculation of coal consumption and pollutants emission being analysed.It is believed that the main factor affecting the uncertainty degree in calculation of coal consumption and pollutants emission is the uncertainty of B kind resulted from indicating value of the adopting measuring instruments.Before the coal comsumption curve being fitted

the data need to be smoothed and excluded from pre-processing.The coal consumption rate curve is suitable to adop the hyperbolic form

while the coal consumption curve has to be a quadratic curve.Finally

a comprehensive calculation method of net coal consumption and pollutants emission

as well as the way of thinking for evalvating the actual concentration of SO2 at exit of the chemney are given.
