Question 1 This question is worth 15 marks. In Chapter 6.1.2 of the Part 2 text you learned a little about fossil-fuel-fired power stations and Activity 8.1b of the online material looked at using waste as an energy source. You may need to refer to the remainder of Chapter 6 and part of Chapter 7 for Parts (b) and (c). An energy generation company is considering two main options when designing a particular power station: either to burn waste wood from local construction and manufacturing operations, or natural gas. In many ways, a wood fired power station is similar to a municipal waste fired plant. a. If the company opts to use waste wood rather than gas, it will require particular facilities and plant items. Refer to Activity 8.1b and compare with the information in Chapter 6.1.2. Give four examples of the additional equipment needed when burning waste wood. (4 marks) b. If waste wood was selected as the fuel, the electricity generated would be classed as 'renewable'. Explain why, and in what circumstances, this is the case. (5 marks) c. If the heat of combustion of waste wood is 11.0 MJ kg-1 and the power station generates electricity with an efficiency of 25%, calculate how much electrical power can be produced (in units of MW) if the power station burns 8 tonnes per hour? Give your final answer to 2 d.p. (6 marks)
