Abstract
A general analysis of heterogeneous sources of waste heat at thermal power plants, taking into account the advanced world and domestic experience in creating high-power steam compression and absorption thermal transformers, has shown the possibility of significantly reducing heat losses by integrating absorption heat pumps and refrigerating machines of various designs and capacities into the thermal circuits of existing and projected thermal power plants. It is proposed to carry out a comprehensive optimization of the plants by creating intra-plant trigeneration systems. Taking into account the specific operating conditions of steam turbine condensers, cheaper multicomponent LiCl salt-based aqueous solutions, which are not inferior in efficiency to imported LiBr solutions with anticorrosive additives, are offered for the use as working bodies.
