Repowering Existing Steam-Turbine Units by Topping Gas-Turbine Units with Partial Oxidation of Natural Gas

摘要

One possible scheme of topping existing and newly created steam-turbine units is a gas-turbine installation with patria oxidation of natural gas in the combustion chamber and subsequent reburying of the partially oxidized products in the furnace of the steam boiler considered in this paper. A comparison is made of the thermal efficiency of various modifications of the proposed scheme with other possible alternatives of the topping of the steam-turbine unit. The necessary capital expenditures for all of the considered alternatives are estimated proceeding from the same premises.
