Abstract

The article views prospects of application of energy-saving technology in heat sources and plants that consume thermal energy in the form of steam and hot water. This technology involves creation of a two-phase medium in the transonic jet nozzle apparatus. The effectiveness of the transonic jet nozzle apparatus is compared with the recuperative heat exchangers effectiveness. The use of these devices allows to obtain economic benefit by reducing the required building volume to accommodate the transonic jet nozzle apparatus, increasing performance coefficient compared with conventional recuperative heat exchangers and reducing operating costs. Two operation modes are considered: “pump-boiler” and “boiler”. The most effective is “pump-boiler” mode, because, in this case, more energy saving is obtained through acting powerful network pumps only as launchers. An example of the use of transonic jet nozzle devices in the Samara region is given in the article. The trends and opportunities to solve the task controlling thermobaric parameters by changing the volume fraction of steam in the two-phase medium are studied.
