Method and system to provide thermal power for a power plant.

摘要

A method and a system wherein substantially whole trees (4) are supplied as fuel without being processed into small woodchips or chunks. The substantially whole trees (4) stored in the drying building (2, 3) to lower their moisture content and thereafter are transported to a charge pit (28) located adjacent to a combustion chamber (10). The substantially whole trees (4) are fed into the comb­ustion chamber (10) by a ram feeder (29) and burned therein. The heat created by the combustion is absorbed by a boiler section (40) and in the form of steam it is supplied to a conventional electrical power generator.
