Combined operation of 900MW power plant with the ORC through the bleed steam extraction point and CO2 recovery system
Abstract
The work presented here is aimed at utylisation of waste heat in the reference supercritical power plant in the manner to produce electricity in ORC installation. The waste heat is available in the form of a stream of hot water at 90 C, recovered from the exhaust gases in the amount of 200MW. Such low enthalpy heat source is rather insufficient to produce a good quality vapour to feed the ORC turbine. Therefore an original approach to increase temperaturę of the vapour of ORC working fluid at the inlet to the turbine has been proposed through the use of heat from the bleed steam from the low-pressure part of the steam turbine of the reference power plant. Additionally the system uses heat from the CO2 capture installation. Analysis was accomplished using the Aspen Plus numerical code. Investigated were six working fluids such as propane, izobutane, pentane, ethanol, R236ea and R245fa. In the course of calculations determined were primarily the increase of the unit power and efficiency for the reference case and that with the ORC.
