This paper proposes a method of determining harmfulness of pollutants resulting from the operation of boiler equipment, discusses how the use of heat energy waste resulting from the operation of thermal plants boilers, as heating of the coolant. And is determined by the energy potential of waste heat, calculate the concentration of pollutants in the atmosphere and provide a method of determining the calculated fuel consumption volume of flue gases, amount of contaminants emitted into the atmosphere during operation of boiler enterprises.
Keywords: resources, energy, coolant, contaminants, heat capacity, energy saving
