USE AND DISPOSAL OF ACIDIC WATER CONDENSATE FROM GAS-FIRED BOILER UNITS

During operation in boiler units of modern condensing boilers or modernization old-style boilers, water condensate is formed due to heat-recovery equipment the mode cooling exhaust-gases below dew point vapor. At natural gas burned equipment, range values pH value within 3 ÷ 6. In this connection, problem arises useful use its safe drainage into sewer network. use, resulting can be used for needs (for washing chemical water-purification systems) outside house laundries, greenhouses, swimming pools, etc.). case city network, as a rule, preliminary decarbonization required. This necessary environmental measure and operational standard protect network related including treatment facilities, from premature wear. Among directions known Ukraine, most common are: - by degassing contact method, which consists removing CO2 heated solution blowing air nozzle layer (ceramic plastic), through flows. Degassing occurs instability H2CO3 compound, which, when heated, easily decomposes H2O CO2; decarbonization, combining carbon dioxide an insoluble compound with various reagents, are added container using dispenser; passing granular filter containing calcium carbonate, such marble chips lime. Removal carbonic acid during filtration seen simplest method those considered. On basis authors propose technical developed neutralizer description design operating principle. The paper presents results calculated studies volumes example gas-fired water-heating nominal thermal power 1 MW system simple complex heat. It shown that technologies houses, there different circuit solutions possible evacuation acidic implementation these technologies. cases where it advisable neutralize condensate, effective methods appropriate equipment.
