    IMPROVING THE ECOLOGICAL INDICATORS OF GAS-FIRED BOILER PLANTS AT THE USE OF COMPLEX HEAT-RECOVERY SYSTEMS

    Innovations, Vol. 6 (2018), Issue 2, pg(s) 79-81

    To improve the operational and environmental performance of steam and water-heating gas-fired boilers, is proposed the efficient technology based on an complex heat-recovery system with heating and humidifying the blown air and heating the cold water of the chemical water-purification system. The results of studies on the reduction of harmful emissions into the environment by gas-fired boilers equipped by deep recovery systems of heat of the exhaust-gases are presented. The efficiency of use for reducing the fuel consumption and the level of formation of nitrogen oxides in the boiler furnace of such complex heat-recovery systems is considered. It is shown that the use of these systems secures reducing nitrogen oxide emissions by up to 60% by suppressing their formation in the boiler furnace at the introduction of moisture with blown air and decrease by 8-12% other harmful emissions from fuel combustion due to a reduction in its consumption.
