Development of technical solutions for reducing harmful emissions in hot water boilers with a cyclone-vortex pre-furnaces and a low-temperature heat exchanger

This article discusses the development of a combined solution for reducing harmful emissions in hot water boilers with a cyclone-vortex pre-furnace by injecting water into the combustion zone of gaseous fuel and using the thermal potential of flue gases in a condensing heat exchanger with an active nozzle for deep cooling of flue gases. The problem of exhaust gas heat utilization is currently relevant, since it brings new opportunities for improving the efficiency of power equipment and rational use of the potential of non-renewable fuels.
