The physical and chemical model of formation of balanced combustion products of hydrocarbon fuels is developed, on the basis of which the "The reference book on heating engineering characteristics, thermophysical properties and thermodynamic parameters of combustion products" is implemented in a software environment Delphi. The universal method of ecological audit of nitrogen oxide emission which allows to estimate the influence of basic determining factors (including mixing method - preliminary, diffusive or combined; structural features of fuelburn devices; excess coefficient of oxidant and concentration of oxygen in oxidant; temperatures of oxidant; specific time of residence in combustion zone and temperature within this area) on the level of toxic NOx concentration in combustion products of hydrocarbon fuels is developed on the basis of thermal theory of nitrogen oxide formation. The methods and ways of increasing of thermal efficiency of gas turbine plants (GTP) are developed on the basis of application of inner and outer cycle technologies of utilization of residual thermal potential of combustion products of GTP, including afterburning in the exhaust nozzle of the device. The methods of increasing of power efficiency and unit power of monic gas and steam plants (MGSP) are offered on the basis of the developed enthalpy and entropy method of thermodynamic analysis of the GTP and combined cycles. The double-fuel technology of MGSP application which allows to shorten the consumption of deficient natural gas as much as twice by means of its substitution by low-grade fuels of a different kind (gas, liquid and solid) and origin is elaborated. The tubular technology of gas combustion which provides the decrease of level of thermodynamic irreversibility of processes in the combustion chamber of the GTP and leads to 10% of economy of primary energy carrier, while plant operates with modernized variant of combustion chamber, is developed and fulfilled.
