gasification - wikipedia

Gasification - Wikipedia

Gasification is a process that converts biomass- or fossil fuel-based carbonaceous materials into gases, including as the largest fractions: nitrogen (N2), carbon monoxide (CO), hydrogen (H2), and carbon dioxide (CO2). This is achieved by reacting the feedstock material at high temperatures (typically >700 °C), without combustion, via controlling the amount of oxygen and/or steam present in

4 Environmental Impacts of Renewable Electricity

The high land-use requirements for biopower shown in Figure 4-4 assume that the feedstocks have been cultivated for energy production; if waste biomass is used as the feedstock, the land-use impacts are significantly lower. In China, the biomass materials likely to be used for electricity generation are mainly agricultural residues (e.g., straw

Agricultural Anaerobic Digesters: Design and Operation

Hot water from a gas-fired standard cast-iron boiler (Figures 50, 51) was forced through the pipes by a circulation pump. The boiler was fired with LP gas for start-up and switched to biogas when production permitted. Thereafter, the boiler was operated on biogas entirely, except for its pilot light, which used LP gas continuously.
