Abstract:
A three-stage steam-jet ejector EPO-3-200 with a working steam flow rate of 850 t / h is installed at the Combined Heat and Power Plant-2 of the city of Almaty on heating turbines. In this paper, the replacement of the existing three-stage steam-jet ejector with a two-stage steam-jet ejector is proposed and substantiated. As a result of the replacement, they obtained a saving of heat (steam) for their own needs for the production of electrical energy. It has been established that at a pressure in the turbine condenser significantly lower than 100 kPa, it is advisable to install a new two-stage

Abstract:
The steam jet ejector is a device for extracting NCG from the condenser. NCG can increase the pressure in the condenser until a vacuum condition is not reached. The diffuser pressure on the steam jet ejector has a normal operational limit of below 1 atm, meaning that the ejector performance will be optimal if it is operated at the operational limit under vacuum conditions. The expected objectives are to determine the effect of the steam jet ejector on condenser vacuum, calculate the performance of the first level steam jet ejector through pressure analysis in the diffuser section, calculate th

Abstract:
Steam or water injection has become the state-of-the-art abatement technique for NOx, with steam strongly preferred for combined-cycle application. In combined-cycle plants, the degradation of the plant efficiency due to steam injection into the gas turbine combustor provides a powerful incentive for minimizing this flow over the entire plant operating map. This paper presents the results of extensive tests carried out on a variety of gas turbine combustor designs. Both test stand and field test data are presented. The usual fuel in the tests is methane; however, some data are presented for co

Abstract:
Background. Currently, in the cycles of steam-ejector refrigeration machines (SERM) are used monoagent jet compressors, the working body in which is water. Despite their low efficiency, SERM have a number of advantages over refrigeration machines that usemechanical compressors: low cost, ease of manufacture and reliability. The use of SERM is largely limited by the inability of these installations to reach temperatures below 0 °C. This limitation can be overcome by applying a fundamentally new steam compressioncycle using a bioagent (water-freon) jet compressor (BAJC).Objective. The purpose of

Abstract:
The review of works on study of dynamics formation of water fluid jet of supercritical parameters outflowing from a high-pressure chamber through a thin nozzle has been carried out. The system of model equations describing the dynamics of outflow processes in both single-phase and multiphase gas-vapor-liquid media is considered. It based on the laws of conservation of mass, momentum and energy of phases in accordance with single-pressure, single-speed and two-temperature approximations with the allowance for contact-type heat transfer and mass transfer for evaporation and condensation under eq

Abstract:
Metal matrix composites (MMCs) have been found to possess tremendous prospective engineering applications that require materials offering a combination of lightweight with considerably enhanced mechanical and physical properties. However, the applications of MMCs are limited by their poor machinability which is a result of their highly abrasive nature that causes excessive wear to the cutting tools. In this study, an investigation into the mechanism of the tool wear in cutting of MMCs is carried out. It is found that during cutting of an MMC, the tool cutting edge will impact on the reinforcem

The phenomenon of direct-contact condensation gains attention because of various industrial applications; nuclear reactor emergency core cooling systems,steam driven jet injectors, direct-contact heat exchangers etc..The phenomenon was investigated computationally by injecting an inclined steam jet using a supersonic nozzle submerged in subcooled water. The condensation mechanism is based on two resistance model, which involves consideration of the heat transfer process on both sides of the interface along with use of a variable steam bubble diameter. For computations, ANSYS Fluent based Euler
