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 twophase 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: "pumpboiler" 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.
Vent emissions from industrial enterprises cause air pollution to a great extent. These emissions contain solid or liquid particles. it is necessary to install cleaning units for those particles. Existing methods of cleaning as applied to fine droplet aerosols have a number of limitations, especially within liquid disperse phase. This is why it is relevant to design highly-efficient cleaning units for vent emissions refining from droplet aerosols of sub-micron sizes. The research reveals the most important parameters for designing highly-efficient cleaning units for vent emissions refining from droplet aerosols. The authors designed a pilot plant and performed a series of experiments to define the optimal geometrical characteristics and modes of operation for cleaning units. These theoretical and experimental studies mase it possible to design three types of cleaning units with precipitating elements in the form of pipes and slotted channels with L/D = 250 dimensions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
