4. A coal-fired power plant has thermal efficiency, η = 30%. It produces 100 MW of power. does the coal combustor transfer energy (heat) to the plant? Answer: 100 MW At what 0 < 400 MH At what rate is heat rejected to the environment? Answer: 100 MW < Qく400 Mw. a. rate b.

In a large steam power plant, the combustion of coal provides a heat rate of - 2500 MW at a flame temperature of T-1000 K. Heat is rejected from the plant to a river flowing at T. = 300 K. Heat is transferred from the combustion products to the exterior of large tubes in the boiler by way of radiation and convection, through the boiler tubes by conduc- tion, and then from the interior tube surface to the working fluid...
Problem 3. Rankine Cycle (90 points) A steam power plant operates with high pressure of 4 MPa and has a boiler exit at 600°C receiving heat from a 700° C reservoir. The ambient air at 20°C provid...
Problem 3. Rankine Cycle (90 points) A steam power plant operates with high pressure of 4 MPa and has a boiler exit at 600°C receiving heat from a 700° C reservoir. The ambient air at 20°C provides cooling to maintain the water/vapor mixture in the condenser at 60°C. All components are ideal (i.e., reversible) except the turbine which has an efficiency 92% ofa reversible isentropic process. Other than the irreversibility of the turbine, the power plant can be considered as...
