Question

4. Petacalco is a coal-fired power plant in La Union, Guerrero. In 2002, it had an installed capacity of 2100 MW, and produced 13,870.47 GWh. To produce this amount of energy, the plant used 957.53 m3 of fuel oil, 3631.24 kt of bituminous coal, and 6650 m3 of diesel. Diesel and fuel oil were burned in boilers having a normal configuration; while coal was burned in a wett-bottom furnace. Estimate the total amount of CO2 emitted to the atmosphere during the year 2002. Note: Use the emission factors for electricity production in Mexico, shown in next page.

Answer 1

The question hasn't been able to reproduce the table that you probably intended to reproduce. However, I had a look at the reference you have given in the question and solved the question, on the basis of that.

Fuel	Reactor type	Emission factor from the reference	Amount of that fuel burned	Total Emission from that fuel type	Total CO2 emitted in 2002
Fuel Oil	Normal Configuration	3.24 t/m^3	957.53 m^3	3.24*957.53 t CO2 (3102.3972)	5342017.75568 tCO2
Diesel	Normal Configuration	2.66 t/m^3	6650 m^3	2.66*6650 t CO2 (17689)
Bituminous Coal	Wet Bottom Furnace	1.465402 t/t	3631.24 kt (kilo tonne) or 3631240 t	3631240*1.465402 t CO2 (5321226.35848)

Hope this helps! It basically just multiplying the amount of fuel used to its emission factor and then adding the emissions from individual fuel types.
