An anaerobic digestion system generates 10,000 m3 (353,150 standard ft3) of biogas per day. The produced biogas is to be used in an engine generator for generating electricity for wastewater treatment plant operations. How much electricity can be generated from the biogas? Answer: 21,795 kWh/day.
A 60 MW steam power station has a thermal efficiency of 30%. If the coal burnt has a calorific value of6950 kcal/kg, calculate :(i) the coal consumption per kWh,(ii)the coal consumption per day.
If we want to have a generator burn methane and produce 2.5 kWh, how much COD is needed, assume a generator efficiency of 66% and STP.
