Although circulating water is cheap and easy to be obtained, the temperature range is small, and has a high dependence on the high-temperature compressor, so the performance is also limited.
As was expected, compressor overheating and irreversible high temperatures at a compressor discharge port were found at the beginning of compressor operation, which is critical, and hence, the authors used a water injection cooling system for the compressor to alleviate temperature overshooting.
The paper presents the 0D models of selected auxiliary equipment of Solid Oxide Fuel/Electrolysis Cell hydrogen peak power plant, i.e., hydrogen compressor, high temperature heat exchanger, and a water pump, which has been calibrated to the appropriate available experimental data.
The designed heat exchanger weights 2.04 kg which is able to cool the high temperature air from high pressure compressor in aero engine for more than 200 K (in certain cases) in a very limited space by using the coolant air from bypass duct.
The high operating pressure of a twin-screw compressor employed in high temperature heat pump or NH3/CO2 cascade refrigeration systems often leads to extremely large axial force on the compressor rotors.
Design models of multi-stage, axial-flow turbine and compressor are developed for high temperature nuclear reactor power plants with Closed Brayton Cycle for energy conversion.
This methodology is applied for compressor housings and also for high temperature turbine housings.
A design study of multistage axial helium compressor of a 300 MWe high temperature gas-cooled reactor is presented in this paper.
In this paper, a capacity-regulated high temperature heat pump (HTHP) system using a twin-screw compressor was designed to recover waste heat in dyeing industry.
The economised vapour injection (EVI) compressor has the capability of overcoming some of the difficulties of high temperature lift operation during cold ambient conditions.
