I believe code requires a dedicated 20-amp circuit for the refrigerator. However, a 20-amp receptacle is not required unless it's the only one in the circuit. Since a duplex receptacle counts as two, a 15-amp receptacle is OK. 08-20-07, 08:47 AM #3.
biogas plant. Biogas means a gas produced by the anaerobic digestion or fermentation of organic matter. The organic matter can be manure, sewage sludge, municipal solid waste, biodegradable waste or any other biodegradable feedstock. Biogas is mainly methane and carbon dioxide. Depending on where it is produced, biogas is also called: swamp gas; marsh gas; landfill gas; digester gas; Biogas can be used as a vehicle fuel or for generating electricity. It can also be burned directly for cooking, heating, lighting, process heat and absorption refrigeration.
Waste/By â product Hydrogen. Biogas Biogas,including anaerobic digester gas, can be reformed to produce hydrogen and used in a fuel cell to produce significant amounts of electricity and heat. Whenbiogas is produced and used onâsite in a fuel cell, fuel utilization oroverall energy efficiency can reach 90% and can reduce emissions by more than 90% by weight as compared to the emissions associated withgrid electricity generation. Inaddition to fuel cells for onâsite power generation, the hydrogen produced using biogas can be used to power vehicles. Wastewater treatment plants (WWTPs), waste streams from food and
