Directing against the features of extraction condensing co-generation unit

which supplies two kinds of unequivalent energy

i.e.heat energy and electric energy

the heat load and electric load of extraction condensing unit have been resolved into two parts

i.e.thermification power generation part and condensation power generation part.Through the resolving coefficient

the heat Absorption of boiler and electric load of the condensation power generation part have been calculated

obtaining the specific heat consumption

and taking it as the specific heat consumption of surplus load which hasn't included in the electric load determined by heat

and the concrete calculation method and examples of application being given

providing basis for energy-saving power generation dispatch.
