Q.3 A. a company uses a steam at a rate of 300000 lb/hr by burning gas as a fuel which costs $5/10 Btu. The cost of this gas annually is $ 2500000/year. In another side this company produces a waste in a quantity of 40000 ton/year, this waste has been analyzed and found to contain 10% ash. The energy content of this waste is about 32600 kJ/kg. the efficiency of the fired system was 80%. The company was paying the cost of transportation of the waste to the landfill of about $1.25/ton plus $2.5/ton landfilling and typing fee. Being a consultant energy engineer of the company give a decision whether using a waste as a fuel is profitable as ar alternative or not?
