The authors consider schemes of gas turbine power units with above-critical carbon dioxide parameters designed for industrial heat recycling at manufacturing enterprises or gas turbine electric power stations. An approach to selection of such schemes was formulated and justified. The authors propose multi-threaded variants of heat schemes for recycling facilities which allow to increase the coefficient of heat usage. Thermo dynamic cycles of carbon-dioxide above-critical gas turbine devices were investigated for the proposed schemes. Possibility of significant increase in the degree of utilized heat, up to 2/3 of the total amount of disposed heat, was demonstrated.
