In a refrigeration cycle that is used to cool products of a grocery store has
an efficiency of 46 %. The total heat load of the grocery store in weekdays
is 50 kW while in weekends is 100 kW. If the system uses electricity that
could power the store within the whole month. What will be its
consumption for a month? *

Consider a 400-MW, 32 percent efficient coal-fired power plant that uses cooling water withdrawn from a nearby river (with an upstream flow of 10-m3/s and temperature 20 °C) to take care of waste heat. The heat content of the coal is 8,000 Btu/lb, the carbon content is 60% by mass, and the sulfur content is 2% by mass.
How much electricity (in kWh/yr) would the plant produce each year?
How many pounds per hour of coal would need to be burned at the plant?
Estimate the annual carbon emissions from the plant (in metric tons C/year).
If the cooling water is only allowed to rise in temperature by 10 °C, what flow rate (in m3/s) from the stream would be required?
What would be the river temperature if all the waste heat was transferred to the river water assuming no heat losses during transfer?
Estimate the hourly SO2 emissions (in kg/h) from the plant assuming that all the sulfur is oxidized to SO2 during combustion.
A 600 MW coal-fired power plant has an overall thermal efficiency of 38%. It is burning coal that has a heating value of 12,000 Btu/lb, an ash content of 5%, a sulfur content of 3,0%, and a CO2 emission factor of 220 IWmillion Bin. Calculate the heat emitted to the environment (Btu/sec), the coal feed rate (tons/day), the degree (%) of sulfur dioxide control needed to meet an emission standard of 0,15 lh SO2/inillion Bin of heat input, and the CO2 emission rate (metric tons/day).
