How Is Efficiency Calculated in Coal Gasification Projects?

Click For Summary
SUMMARY

The efficiency of a coal gasification project using 26,000 tons of coal per day to produce 250,000,000 cubic feet of natural gas is calculated using the formula: efficiency = energy output / energy input. The energy content of the coal is 8,700 BTU/lb, while the gas has an energy content of 950 BTU/cubic foot. The calculated efficiency is based on these energy values, and any doubts regarding the calculation method should be addressed by verifying the energy input and output values used in the formula.

PREREQUISITES
  • Understanding of energy content measurements (BTU)
  • Knowledge of coal gasification processes
  • Familiarity with efficiency calculations in energy production
  • Basic algebra for solving equations
NEXT STEPS

Homework Statement



For a gasification project being planned, 26000tons of coal per day will be used to produce 250000000 cubic ft per day of natural gas. if the coal is rated at 8700btu/lb and the gas at 950btu/cu ft. what will the efficiency will be?

Homework Equations



efficiency = energy output/energy input

The Attempt at a Solution


i calculated the energy content of both coal and gas and afterwards calculated the efficiency. however i have my doubts if it's the correct way to answer the question.
