Question

Penticton discards roughly 200 000 kg of  MSW per year. The LHV of those discards is about 12,000 kJ/kg. A mass-burn waste to energy facility can convert those wastes to electricity with a heat rate of 17,000 kJ of thermal input per kWh of electrical output (roughly 20% efficiency). Estimate the electrical energy that could be produced in kWh per year if all our discards were used in this WTE system. (Enter your answer as a whole number without units. For example: if your calculated answer is 6,030.87 kWh/year please enter 6031])

Answer 1

Dear student, we shall solve this problem by simple mathematics where we know that 1KWH power us produced from 17000 KJ Thermal input. We have total MSW produced per year and it's LHV. Multiplying both gives us annual thermal input in KJ/YEAR. Using this value and data provided in question regarding thermal input and power we shall find answer.

Dear student, two answers have been put by rounding off to nearest high integer and nearest lower integer. Kindly consider it please as per desired answer.

Dear student if you have any query kindly ask me. I shall definitely help in resolving your query. Please ask me. Thank you.
