System for transferring heat from combustion process in wood-fired boiler system to organic rankine cycle process for power production in cogeneration plant, has condensers in which steam is condensed, cooled and flowed back into evaporator

摘要

The system has a primary circuit with a fluid medium (4) i.e. water, that is heated and evaporated by radiation and/or convection of exhaust gas (1) over an evaporator (11). Steam is condensed and cooled in parallely connected condensers (12-14) that are arranged at higher level, and flowed as condensate over gravitational force back into the evaporator. A circulation of the medium is maintained by the force. The condensers extract heat in the condenser (12) and couples the heat in a heat supply system.
