DECREASING CONSUMPTION OF MAKE-UP WATER AT COMPLEX HEAT-RECOVERY UNITS

The energy-saving technical solution of a complex heat-recovery unit designed for heating and humidifying the combustion air of gas-fired boiler plants has been proposed. The schematic circuit of this unit with a new design of elements is given, which provides compensation for the corresponding amount of water evaporated into the combustion air, using a layer of porous granulate in the water circulation line of the unit to neutralize the resulting condensate.
