Biogas - Wikipedia

Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen (anaerobically), primarily consisting of methane and carbon dioxide. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste.Biogas is a renewable energy source.. Biogas is produced by anaerobic digestion

Heating Fuels - Propane Vs Oil | Which Is Better?

A high eff gas condensing boiler installed in a home that was designed for oil heat with conventional baseboard is not the best answer! A condensing boiler needs to have a return water temp of below 140-150 to actually condense this is great during the mild days of spring and fall but during the winter the boiler will need to be pumping out 180

Hydraulic Calculations for Sprinkler Systems

Hydraulic calculations are a very important step when designing fire protection systems, since they ensure the flow rate established through the piping network will be enough to control fires effectively. Calculation procedures are established in model codes: automatic sprinkler systems are subject to NFPA 13 (National Fire Protection Association) in the USA, while the the international

Direct Capture of CO2 from Ambient Air | Chemical Reviews

Typically, the flue gas needs to be previously desulfurized to a great extent—which is compulsory by law in most countries. The main disadvantage of this approach is the reduced CO 2 concentration, which ranges from ∼4 vol % for a natural gas combined cycle processes to 13–15 vol % for a coal-fired combustion plant.
