The purpose of research - development of technologies of contact gas-steam turbine plant cycle with heat recovery and the mass of the working fluid through the intensification of processes of heat and mass transfer and separation using a portion of unsteady flow and temperature relaxation of the liquid during evaporation and condensation in the flow of the gas-steam mixture. The studies were carried out by an analytical method for mathematical modeling of the mechanics of movement, heat and mass transfer before heat trasfer agents in elements of KGSTP to ensure the generation of water. It was confirmed that the initial increase in humidity and temperature reduction gas-steam mixture entering the contact condenser provides heat and mass transfer intensification portion using unsteady flow and fluid temperature relaxation on evaporation and condensation in a flow of the gas-steam mixture. To intensify the separation in addition to inertia forces to further apply force turbulent diffusion, thermal and turboforez. Intensification of these processes ensure stable excess water generated in the cycle setting throughout the year. It was found that the intensification of heat and mass transfer processes and separation during evaporation and condensation in the gas-steam mixture flow is provided through the use of evaporative cooling gas-vapor mixture under irrigation mineralized water; use of surface boiling mineralized water and found that the latter method is the most effective. It was determined that the intensification of heat and mass transfer and separation using a portion of unsteady flow and temperature relaxation of the liquid during evaporation and condensation in the flow of the mixture allows for the generation of a stable water cycle KGSTP in October and April to get further demineralized water excess amount with respect to steam boiler scrappage 1,229 ... 1,369, and in the period from May to September - additional desalination of water is 1,080 ... 1,280, provided that the amount of desalinated water is spent on KGSTP. It was found that the most effective for the production of electricity, thermal energy and demineralised water is to use KGSTP evaporative cooling and additional cooling circulating water before and regeneration of its heat after contact condenser or use desalination apparatus boiling type with additional heat recovery mineralized water that is discharged from the apparatus. This made it possible to increase the heat utilization rate, as the technical and economic indicators of competitiveness of the plant, from 0,41…0,43 to 0,95…0,97 compared to KGSTP, which produces only electrical energy. One of the possible areas of use of the research is energy. Product Description popup.authors В.В. Кузнецов С.А. Кузнецова С.С. Рижков popup.nrat_date 2020-04-02 Close
