An industry is proposing to construct a new coal-fired power plant that produces 2300 MW electricity with efficiency of 39%. Coal has a heating value of 10,750 Btu/lb, and contains a sulfur content of 2.4%. It is expected that 95% of sulfur will be converted to SO2. The New Source Performance Standards (NSPS) limits the SO2 emission rate from any coal-fired power plants to 1.2 lb/ 106 Btu heat input. Use the engineering calculation approach to determine the followings. a) Coal consumption rate in lb/hr b) SO2 emission rate in lb/hr c) Determine if the newly proposed power plant is required to install a flue gas desulfurization (FGD) process for SO2 removal from the flue gas. What percent SO2 removal is required?

Question
An industry is proposing to construct a new coal-fired power plant that produces 2300 MW
electricity with efficiency of 39%. Coal has a heating value of 10,750 Btu/lb, and contains a
sulfur content of 2.4%. It is expected that 95% of sulfur will be converted to SO2. The New
Source Performance Standards (NSPS) limits the SO2 emission rate from any coal-fired
power plants to 1.2 lb/ 106 Btu heat input. Use the engineering calculation approach to
determine the followings.
a) Coal consumption rate in lb/hr
b) SO2 emission rate in lb/hr
c) Determine if the newly proposed power plant is required to install a flue gas
desulfurization (FGD) process for SO2 removal from the flue gas. What percent SO2
removal is required?
