• W4246834527 abstract "SUMMARYNew possibilities in district heating can be achieved by applying the principles of an electrically-driven heat pump; larger capacities can be obtained by a gas turbine. Cooling water from an electric power station can also be used as a heat source for the heat pump.The advantages of such a combination are the following:-high coefficient of performance and an excellent unit capacity factor;-high flow temperature in district heating by using the waste heat of a gas turbine;-application of cooling water heat or other industrial waste heat in the heat pump cycle;-better adaptation via central heat generation to the different fuels, an easier reserve capacity, lower emissions and thereby greater environmental protection;-the possibility of combination with a coal gasification plant.The use of a gas turbine with an electric power output of about 5,000 kW, equipped with an air/gas heat exchanger, can give a thermal power of 18,600 kW (16 Gcal/h) having a coefficient of performance of 2.1 and a unit capacity factor of 120 per cent. In the heat exchanger, by absorbing heat, the cooling water of an electric power station is cooled from 35 to 10°C.In the heat exchanger delivering heat, the returning heat arrives with a temperature of 55°C and is heated up to 75°C. In the gas turbine waste heat exchanger, the full flow can be increased to 90°C or a partial flow to higher temperature according to the outlet temperature of the gas turbine air/gas heat exchanger. Dry air is a medium for the heat pump cycle. For a plant of this type it must still be proved whether other gases, inert gases or refrigerants are suitable and what are their advantages. Compression and expansion of the dry air is made by turbo machines.The plant costs which seem to be high at first - and thereby the heat generation costs - can be reduced by using the plant in base load and decreasing specific costs when using larger units. It must be taken into consideration that, by the unit capacity factor of such a plant, further economic advantages are to be expected in future, when fuel prices increase.If there is no cooling water available as a heat source from an electric power station, the heat extraction from a part of the return, not to be heated up in the heat pump cycle, has economic advantages compared to a conventional heating or heating/power station. The fuel supply of the gas turbine can also be realized by a clean low BTU gas from a coal gasification plant. The steam which is produced in the waste heat boiler after the gasifier can be used for driving the air compressor of the gasifier and for delivery of process and heating steam, as well as for heating water production.Also it is of great importance that the application of fuel oil be essentially reduced by using a heat pump gas turbine plant in combination with a coal gasification plant? the security of energy supply is increased and a part of the lost market is restored to hard coal." @default.
