METHODE ANWENDBAR BEI KLEINEN KRAFTANLAGEN

摘要

The invention concerns a method in small-power plant use for intensification of the operation of the power plant. The order of magnitude of the small power plant is in the range of 3... 30 MWe. In the method, the flue gases (L2) are removed out of connection with the boiler structure so that the last heat face at which the flue gases deliver heat is the economizer (16) placed in the boiler structure. The flue gases are removed from the boiler at a temperature of 95 DEG C... 150 DEG C. In the method, the combustion air is introduced into the furnace (M) as pre-heated while for the pre-heating of the combustion air using exclusively the condensing heat of the bled steam or back-pressure steam of the turbine or supply water that has been heated by said steams.
