- My Question: In the steam power plant of problem #1, the reheater developed a leak and it was decided to run the plant bypassing the reheater at 1 bar. Determine the thermal efficiency and boiler capacity to develop the same power output.Problem#1. In a Reheat Cycle steam enters the turbine @ 40 bar and 400 C. It expands isentropic ally to 6 bar and is reheated at constant pressure to 400 C. This steam expanded isentropic ally to 1bar and is reheated at constant pressure to 200 C. Finally this steam is expanded isentropic ally in the condenser pressure of 0.1 bar. Determine the thermal efficiency and the capacity of the boiler if 10,000 KW of power output is required.Q2) A vapor-compression heat pump with a heating capacity of 500 kJ/min is driven by a power cycle with a thermal efficiency of 25%. For the heat pump, Refrigerant 134a is compressed from saturated vapor at -100C to the condenser pressure of 10 bar. The isentropic compressor efficiency is 80%. Liquid enters the expansion valve at 9.6 bar, 340C. For the power cycle, 80% of the heat rejected is transferred to the heated space. (i) Determine the power input to the heat pump compressor, in kW. (ii) Evaluate the ratio of the total rate that heat is delivered to the heated space to the rate of heat input to the power cycle. Discuss.Subject: Thermodynamics Why Rankine cycle still being used in steam power plants instead of the Carnot cycle considering that the Carnot cycle is higher in cycle/thermal efficiency?
- 1) (p12pp5Dimagiba) - A reheat cycle with two stages of reheating is executed with steam expanding initially from 200 bar and 540 C. The two reheater pressure are 40 bars and 10 bars, and the steam leaves each reheater at 540 ☐ C. Condensation occurs at 60 ☐ C. Sketch the schematic diagram, and Ts diagram. For the ideal cycle and 1 kg/s of steam, Find: a) QA and e b) For the engine, ignore the pressure drop through the reheater, let the engine operate through the same stages and compute W. and e.My Question: In the steam plant problem#2, the reheater developed a leak and it was decided to run the plant bypassing the reheater. Determine the thermal efficiency and steam flow rate to develop the same power output.Problem 2 (In a reheat cycle steam enters the high-pressure turbine at 40 bar and 400C. It expands isentropically to 6 bar and is reheated at constant pressure to 400C. This steam is expanded isentropically in the low pressure turbine to the condenser pressure of 0.1 bar. Calculate the thermal efficiency and steam consumption for 10 MW output.)In simple and clear explanation, what is polygeneration system?
- 4. Water is the working fluid in a vapor power plant. Superheated steam leaves the steam generator at 8.2 MPa, 540 °C and enters the turbine at 7.5 MPa, 500 °C. The steam expands through the turbine, exiting at 8 kPa with a quality of 94%. Condensate leaves the condenser at 5 kPa, 30 °C and is pumped to 9 MPa before entering the steam generator. The pump efficiency is 80%. Determine (a) the thermal efficiency of the cycle and (b) the net power developed. (c) What-if Scenario: What would the net power developed be if the mass flow rate of steam were 15 kg/s ?2. Steam at 10MPaa, 550°C enters an ideal engine that has one stage of regenerative cycle; condenser pressure is 10 kPaa and extraction of steam is at 1 MPa.The net power output of the turbine in an ideal reheat-regenertive cycle is 100 MW. Steam enters the high-pressure (H.P.) turbine at 90 bar, 550°C. After .expansion to 7 bar, some of the steam goes to an open heater and the balance is reheated to 400°C, after which it expands to 0.07 bar. (a) What is the steam flow rate to the H.P. turbine? (b) What is the total pump work? (c) Calculate the cycle efficiency. (d) If there is a 10c°rise in the temperature of the cooling 'water, what is the rate of flow of the cooling water in the condenser? (e) If the velocity of the steam flowing from the turbine to the condenser is limited to a maximum of 130 m/s, find the diameter of the connecting pipe.
- Power plant .The regenerative cycle3- A reaction turbine is supplied with steam at (60 bar, 600 C°). The condenser pressure is (0.07 bar). If the reheat factor can be assumed to be (1.04) and the stage efficiency is constant throughout at (80%). Calculate the steam flow required in (ton/hr) for a diagram power of (25 MW). (Ans. 75.6 ton/hr) 4- The steam consumption at full load for a (3 MW) turbine is (16.6 ton/hr). At half load the steam consumption is (9.1 ton/hr). Applying Willan's line, estimate the steam consumption at no load, and the consumption at a load of (2.5 MW). (Ans. 1.6 ton/hr; 14.1 ton/hr)Steam enters the turbine of a vapor power plant at 600 lbf/in.?, 700°F and exits as a two-phase liquid-vapor mixture at 90°F. Condensate exits the condenser at 85°F and is pumped to 600 lbf/in.2 The turbine and pump isentropic efficiencies are 90 and 80%, respectively. The net power developed is 1 MW. Determine: (a) the percent steam quality at the turbine exit. (b) the percent thermal efficiency. (c) the steam mass flow rate, in Ib/h.
