Hybrid, coal-powered power station

摘要

The hybrid power station according to the invention is characterised in that the combustion air and the finely pulverised coal are introduced into furnaces 2 in which the coal produces a combustion gas; in that most of the ashes are removed in the moulten state in order to carry out a primary dust separation operation; in that the dust in the combustion gas is removed by a cyclone 20 placed in the furnace 1 in order to carry out a secondary dust separation operation; in that the dust removed is subjected to a heat exchange with secondary air in a cooler 4 placed in the lower part of the furnace 1; in that the temperature of the gas leaving the furnace 1 is adjusted by mixing the combustion gas with the secondary air; in that the dust in the combustion gas leaving the furnace 1 is eliminated by a precision dust separator 5 in order to carry out a tertiary dust separation operation; and in that the combustion gas is sent to a gas turbine 6. Use of the lost furnace heat to drive turbines and produce electrical energy. <IMAGE>
