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 ...

Biomass heating system - Wikipedia

Buffer tanks. Buffer tanks store the hot water the biomass appliance generates and circulates it around the heating system. Sometimes referred to as 'thermal stores' they are crucial for the efficient operation of all biomass boilers where the system loading fluctuates rapidly or the volume of water in the complete hydraulic system is relatively small.

thermal treatment of biomass | BioEnergy Consult

Sep 07 2020 · Pyrolysis is the term given to the thermal degradation of wood in the absence of oxygen. It enables biomass to be converted to a combination of solid char gas and a liquid bio-oil. Pyrolysis technologies are generally categorized as fast or slow according to the time taken for processing the feed into pyrolysis products.

Zirconia Oxygen Sensors for Boiler Combustion Efficiency

The oxygen to fuel ratio effects boiler efficiency. Too little oxygen results in incomplete combustion creating harmful emissions. Setting the boiler to burn with excess oxygen is the normal solution to reduce emissions but is very inefficient. SST Sensings oxygen sensors allow the excess oxygen to be reduced whilst still maintaining safe ...

Effects of firing coal and biomass under oxy-fuel ...

Nov 01 2013 · Fig. 4 shows the effect on heat transfer at various sections in the boiler when biomass is fired instead of coal in air when thermal input exit oxygen concentration and air in-leakage are kept the same as the air-coal case. Oxygen in the biomass was assumed to be available for combustion and inlet velocities were similar.
