A 440-MW coal-fired power plant is burning coal that contains 185 ppb of mercury. The coal firing rate is 300,000 Ib/hr, and the flue gas flow rate is 1.0 million scfm
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.
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.
