Abstract
A description of the energy-saving technology for the generation of electrical energy is presented in the superstructure of steam boiler houses with turbine-generator units (TGU) with backpressure turbines operating in parallel with reduction cooling units. The characteristics and description of a TGU for distributed energy, developed at OAO KTW, with backpressure turbines and condensing turbines with and without steam extraction, surface and air condensers, and mini-CHPP with built-in boilers for heating network water are given. TGUs are described for geothermal energy with turbine exhaust to the atmosphere or to a heat-supply station with condensing turbines with air condensers. The technical characteristics of TGUs of various types, the number of units produced, and the place of their operation are given. The design features of TGUs manufactured at OAO KTW are noted: block layout, 100% factory readiness, high degree of automation, and reliability during operation. Prospects for further developing the direction of turbine-generator sets for distributed energy are shown: development and delivery of condensing and backpressure turbine-generating sets with a capacity increased to 8 MW; expanding the range of a “connected-in” TGU operating on steam from the extraction or exhaust of the main turbines, which make it possible to compensate for seasonal or technological fluctuations in heat energy consumption and ensure more efficient operation of the main turbines; and development of binary plants using low-grade heat and operating on low-boiling organic heat carriers. High efficiency of distributed power generation in combination with cogeneration is noted.
