An 1-MW combined-cycle, natural-gas power plant has an efficiency of 52%. Natural gas has an energy density (i.e., heating value) of 55, 340 kJ/kg, and about 77% of the fuels is carbon. (a) What is the heat rate of this power plant [kJ/kWh]? (b) Find the emission rate of carbon (C) [kg C/kWh] and carbon dioxide (CO2) [kg CO2/kWh] ? (c) If the power plant runs in full capacity for 8,700 hours per year, how much total electricity energy the plant generate per year [kWh/year]? (d) If the carbon penalty cost set by the Clean Air Act is $10 per every 1,000 kg of CO2, how much would the power plant would pay per year?

A planned electric power generating plant has a design capacity of 250 megawatts. The plant is expected to have an availability of 95%. What is the plant's expected annual output in kilowatt-hours? The electric power generating plant in question 1 will be fired with natural gas. The construction contractor will guarantee a heat rate of 9,800 Btu per kilowatt-hour. The gas used by the plant will have a low heating value (a measure of the energy content) of 950 Btu per standard cubic foot (scf). (There are 1,000 scf in an mcf.) Based on the information given in question 1, how many mcf of natural gas will the plant use during a year?

An old coal-fired power plant runs with a heat rate of 9000 Btu/kWh. The energy content (i.e., heating value or specific energy) of the coal is known to be 24,000 kJ/kg. The coal content includes 62% carbon, 2% sulfur, and 10% unburnable minerals (i.e., ash). (a) What is the fuel rate of the coal [kg/kWh]? (b) What is the carbon emission rate [kg C/kWh]? What is the carbon dioxide emission rate [kg CO2/kWh]? (c) What is the sulfur emission rate [kg S/kWh]? What is the sulfur dioxide emission rate [kg SO2/kWh]? (d) If 70% of the ash is released as particulate matter from the stack (called "fly ash"), what is the uncontrolled particulate emission rate [kg ash/kWh]? (e) What is the efficiency of the power plant?

A single-pressure combined-cycle power plant consists of a gas turbine, HRSG, and steam turbine plant. The gas turbine exhaust gas flow rate is 600 kg/s, temperature is 600°C, live steam condition is 70 bar/500°C, condenser pressure is 0.04 bar, and feedwater temperature is 140°C. Assuming a pinch point of 12 K for both high and low pressure, an exhaust gas specific heat of 1.05 kJ/(kg K), and an isentropic efficiency of the steam turbine of 0.9, calculate: (a) the rate of steam production in kg/s, (b) the stack gas temperature in °C, (c) the steam turbine power output in MW, and (d) the heat transfer rate in the HRSG in kJ/s.
