Рассмотрен один из вариантов энергосбережения в промышленной и коммунальной
теплоэнергетике путем глубокой утилизации теплоты уходящих из котлов продуктов сгорания
газообразного топлива. С помощью разработанной компьютерной программы выполнено
расчетное исследование с целью оценки влияния основных параметров на теплотехнические,
аэродинамические и конструктивные характеристики теплоутилизационной системы и
выбора их оптимальных значений.
One embodiment of saving industrial and municipal thermal power by deep heat recovery boiler flue of combustion of gaseous fuels with condensation of water vapor from them is viewed. 1 ton per hour heat recovery system on the boiler vapor production is built and consists of: boiler, condensing air heater and condensing heat exchanger for heating water, hot water system makes it possible to provide savings of about 12-14 % of the natural gas. While developing a heat recovery system and its elements became clear that effi ciency of the system as well as compactness and low cost heat exchangers requires careful approach to select parameters such as the temperature of fl ue gases, cold water and cold air, spherical diameter of the intermediate coolant, the velocity of gases in the air preheater. To this purpose, the computer program, which is developed for calculation study for evaluating the impact of these parameters on thermal engineering, aerodynamic and structural characteristics of heat recovery systems and heat exchangers, its constituent is fulfi led, and their optimal values has been chosen. The solving of this problem can signifi cantly reduce the cost of developing a heat recovery technology.
