Abstract
Способ работы котельной установки, по которому основной поток вырабатываемого в котле водяного пара направляют в кожухотрубный теплообменник для подогрева сетевой воды до температуры 110-120°C, образующийся в кожухотрубном теплообменнике конденсат водяного пара отводят в сборный конденсатный бак, часть вырабатываемого в котле водяного пара подают в деаэратор для дегазации добавочной воды и конденсата, продукты сгорания природного газа после котла охлаждают в водяном экономайзере до температуры 140-160°C и по основному газоходу направляют в конденсационный поверхностный теплообменник-утилизатор теплоты продуктов сгорания, где осуществляют их глубокое охлаждение до температуры 35-40°C с конденсацией части содержащихся в газах водяных паров, отличающийся тем, что для исключения конденсации в наружных газоходах и в дымовой трубе водяных паров, оставшихся в уходящих продуктах сгорания после их глубокого охлаждения до температуры 35-40°C в конденсационном поверхностном теплообменнике-утилизаторе теплоты продуктов сгорания с конденсацией части содержащихся в газах водяных паров, подогрев уходящих продуктов сгорания до температуры 65-70°C осуществляют водяным паром, вырабатываемым в котле, в поверхностном парогазовом теплообменнике, установленном после конденсационного поверхностного теплообменника-утилизатора теплоты продуктов сгорания перед дымососом.The method of operation of the boiler installation, in which the main stream of water vapor generated in the boiler is sent to a shell-and-tube heat exchanger to heat the network water to a temperature of 110-120 ° C, the condensate of steam generated in the shell-and-tube heat exchanger is diverted to a collection condensate tank, a part of the steam generated in the boiler is supplied to the deaerator for degassing additional water and condensate, the natural gas combustion products after the boiler are cooled in a water economizer to a temperature of 140-160 ° C and sent through the main gas duct surface condensing heat exchanger-heat exchanger of the heat of combustion products, where they are deeply cooled to a temperature of 35-40 ° C with condensation of part of the water vapor contained in the gases, characterized in that to prevent condensation in the external gas ducts and in the chimney of water vapor remaining in the outgoing combustion products after deep cooling to a temperature of 35-40 ° C in a condensation surface heat exchanger-heat exchanger of the combustion products with condensation of part of the water vapor contained in the gases a display, leaving combustion products to a temperature of 65-70 ° C is carried out by steam generated in the boiler, the surface vapor-gas heat exchanger installed after the condensing heat exchanger-surface heat exchanger the combustion products before the exhauster.
