I need help on this assignment: Exhaust gases from the turbine of a simple Brayton cycle are quite hot and may be used for other thermal purposes. One proposed use is generating saturated steam at 110℃ from water at 30℃ in a boiler. This steam will be distributed to several buildings on a university campus for space heating. A Brayton cycle with a pressure ration of 6 is to be used for this purpose. Plot the following:(a) The mechanical power produced,(b) the flow rate of the produced steam,(c) the maximum cycle temperature, all as functions of the rate at which heat is added to the cycle.
A cogeneration system consists of an engine and a boiler, both working with naturalgas. Heat is recovered from the exhaust gases, from the lubrication oil and from theengine cooling water; nonetheless there is the need of further heat from a boiler. Thesystem provides 80 kW of electrical power of 200 kW heat.Calculate :a) Draw a diagram of the facility, indicating the energy flow in each component. b) The ratio heat / work from the engine. c) The Energy Utilization Factor of the power supply system d) The volumetric flow rate of gas (m3/hr) required to power the engine and the boiler. e) What are the annual savings in euros, from this cogeneration system? Data: Calorific value of natural gas 38MJ/m3 Mechanical efficiency of the engine: 35 % Alternator efficiency: 95 % Efficiency of the boiler: 85 % Thermal energy recovered from the engine: 62 % of total energy rejected by the engine. Total annual electricity produced by the system: 500 MWhe Unit cost of gas = 0.01 € / kWh Unit cost of…
Question 2: Consider you have to set a power plant for powering up the up hilled areas of Nathia-Galli Abbottabad by harvesting the hydro-energy from Nathiya-Galli Water-fall. As a major gas pipeline of SNGPL has already been laid near the water-fall, therefore, to low capacity of hydro-energy, we can also set a Gas turbine based Generating units as standby / peak load plant in combination with hydro-turbine plants. (1) You have the availability of both types of Gas Turbines i.e Open Cycle & Closed Cycle. Investigate the feasibility for selection of the type of Gas Turbine Power Plant from above-mentioned types, which will be more suitable under following available conditions / resources: a. Frequently changing Load conditions / constant load conditions b. Cheap fuel / costlier fuels to be used c. Nuclear Reactor based Heat exchangers / Combustion Chamber based Heat Exchangers
A steam power plant operates on a theoretical reheat cycle. Steam at 25 bar pressure and 400°C is supplied to the high pressure turbine. After its expansion to dry state, the steam is reheated at constant pressure to its original temperature. Subsequent expansion occurs in the low pressure turbine to a condenser pressure of 0.04 bar. Considering feed pump work, Calculate: a)Quality of steam at entry to condenser b)Thermal efficiency c)Specific steam consumption.
