Two triple expansion steam engines and an exhaust turbine
it is not based on bunoullies theorem it is based on mach number.when sonic speed of steam converted to supersonic steam by nozzle vacuum is created.
Vacuum is generated by using Ejectors. 1. steam jet ejectors 2. water jet ejectors. may be single, double or 3 effect.
heat losses in condenser in percentage
In modern Combined Cycle Power Stations, the exhaust gas from Gas Turbines, which contains significant amount of heat energy is diverted to water boilers to generate steam which in turn runs Steam Turbines. Usually Two or Three GT's exhaust gas is used to run a ST. The significance of this is that, the otherwise wasted exhaust heat is intelligently used to generate power, thereby pushing the efficiency of a single GT of 25-30 % to a combined cycle efficiency of about 45-50 %. Alternatively in some industries, the exhaust gas can also be used for process heating requirements.
Jet fuel is sprayed into the exhaust gas steam and ignited, as this happens, the end of the primary nozzle constricts hydraulically and the result is increased thrust as the jet exhaust is "after burned".
what is the woking principal of steam jet ejector? limitation of steam jet ejetor?
Jet steam is the pressure steam that is released by the nozzle of the jet engine. Using fuel and air to burn produces this steam that is hot and under pressure for the use of the turbine and provide the thrust needed.The above equations shows this. Normally the jet steam to be discharged is under high temperature and high pressure and it is used to give adequate thrust to the aircraft or to other vehicles having jet engines. Besides imparting thrust, the jet steam plays an essential role of cooling and thermal control of the jet engine.
No. Exhaust steam must be condensed back into water before being pumped back to the boiler. High pressure exhaust is often used to heat production or heating equipment, returned to a condensate tank then pumped to the D/A before being returned to the boiler. Low pressure (vaccuum) exhaust is condensed by a jet condenser or shell and tube condenser before being returned to the D/A.
why we are maintain vacuum in steam turbine at steam outlet or exhaust side
That the efficiency of a Steam Engine could be improved by condensing the exhaust steam.
For steam to come out the exhaust you probably have a bad head gasket or a cracked head. If the turbo had an oil seal fail it would cause blue smoke to come out the exhaust.
exhaust
Because the steam expands as it passes through the turbine. The steam velocity through the turbine is constant from steam chest to exhaust hood (though it changes in each stage). Thus, the space needed for the steam to expand needs to be expanded to correspond with that expansion of the steam.
The Corliss steam engine is remarkable because of the design of the valves which control the intake and exhaust to the steam to the cylinder.
between troposphere and ozone
Yes, a jet has engines, which are often referred to as jet engines. These engines operate on the principle of jet propulsion, where fuel is burned to create high-speed exhaust gases that propel the aircraft forward. Unlike traditional motors that might use propellers, jet engines typically provide thrust directly through jetting out exhaust gases.
