METHOD FOR UTILIZATION OF HEAT ENERGY IN A DISTRICT HEATING NETWORK FROM A GENERATING PLANT WITH AN AIR-COOLED GENERATOR POWERED BY AN INTERNAL COMBUSTION ENGINE, AND A GENERATINGPLANT PERFORMING THE METHOD

摘要

2124573 9311354 PCTABS00022 A method for extracting thermal energy for use in a heat distributing plant, for instance a district heating system, from a generator plant having a generator, which is air-cooled by means of a cooling ventilator and driven by means of an internal combustion engine, according to which method thermal energy from the cooling system and exhaust gas are transferred to the district heating system, and in which the internal combustion engine is enclosed in a sound-absorbing, ventilated cabinet. With a view to being able to exploit the heat transferred to the ventilation air through direct heat exchange with the water in the district heating system, the generator is supplied by cooling air from an external cooling ventilator, and the cooling air outlet is supplied to the cabinet, where it constitutes the whole amount of ventilation air or an essential part thereof.
