Oleksandr P. Energy-efficient steam supply of industrial enterprises with deep utilization of steam energy potential

Thesis is devoted to solving actual scientific-technical task regarding the development and improvement schemes of steam supply systems of industrial enterprises and their technologies with purpose for deep utilization of secondary energy resources and the generation of additional electricity. Based on analytical and field studies are classified and formulated options for steam supply systems of industrial enterprises and their consumers. Specified to the requirements to the relative internal efficiency of turbine technology, which can be used when replacing the pressure-reducing unit of technology consumers. Unlike energy turbines, for turbines of industrial enterprises put forward a requirement to maintain the necessary technological parameters of steam to the consumer, leading to the possibility of lowering the relative internal efficiency and thus to a reduction in capital and operating costs associated with the reconstruction. Showing modernized scheme steam supply systems, for which it is possible to achieve additional capacity at the level of 135-250 kW /(kg/s) on devices with low relative internal efficiency at the level of 60-70%. Together with the increase in the percentage of condensate return, and the disposal of secondary energy resources concomitant increase in power generation of the energy efficiency of the system is 2-4% and the exergy efficiency - 16-22%.
