heal.abstract	A combined power plant is proposed, made up of a gas turbine vapour part, whose rejected heat is used to drive an NH3/H2O-vapour turbine part working with an absorption process similar to that of absorption refrigeration. Waste heat at temperatures up to 400 K from both parts of the combined system may be used for building heating or analogous purposes. The calculation of the described system is performed by a computer algorithm based on analytic functions describing the thermodynamic properties of the working media. The effects of the parameters involved are examined. In the ranges considered, it was found that the theoretical efficiency of the plant may reach 55% and can be expressed as ntot ≈ nG + 0.6nNH3 where nG and nNH3 are the theoretical efficiencies of the gas turbine and the NH3/H2O-vapour turbine parts. The waste heat for building heating may reach 1200 kJ/kg NH3/H2O vapour.	en
