Abstract: The study considers the issues of the rational organization of fuel combustion processes in TPS power boilers. Most thermal electric stations use gas as the primary fuel and fuel oil serves as the back-up fuel. Transition of boilers to fuel oil burning is usually partial and several burners as a rule, operate on the gas burning. At operation of boilers, due to features of the flame formation when fuel oil burning and gas burning, the issue about optimum performance conditions of the radiant heat exchange behavior in boiler furnaces is problematical. At gas burning the flame is non-luminous and at fuel oil burning the flame is luminous, except for core flame and furnace volume at the level of burners. There are differences in temperature distribution along the furnace height, width and depth when gas and fuel oil burning. Depending on the distribution of temperatures throughout the furnace volume, conditions of radiant heat exchange behavior and effectiveness of gas and fuel oil burning in steam boiler furnaces change which is relevant for the improvement of steam boilers economic efficiency. Study of the flame interaction at combined burning of gas and fuel oil and their influence on the radiation heat exchange in boiler furnaces is also relevant for the improvement of steam boilers economic efficiency.
