400kw Gas Generator - China

1 - Thermo-Chemical Process 1)Combustion The cycle used is the conventional rankine cycle with biomass being burned (oxidised) in a high pressure boiler to generate steam.

The net power cycle efficiencies that can be achieved are about 23% to 25%.

The exhaust of the steam turbine can either be fully condensed to produce power or used partly or fully for another useful heating activity.

in addition to the exclusive use of biomass combustion to power a steam turbine, biomass can be co-fired with coal in a coal-fired power plant.

Direct co-firing is the process of adding a percentage of biomass to the fuel mix in a coal-fired power plant.

it can be co-fired up to 5-10% of biomass (in energy terms) and 50-80%6 with extensive pre-treatment of the feedstock (i.e. torrefaction) with only minor changes in the handling equipment.

For percentages above 10% or if biomass and coal are burning separately in different boilers, known as parallel co-firing, then changes in mills, burners and dryers are needed.

2)Gasification Gasification is achieved by the partial combustion of the biomass in a low oxygen environment, leading to the release of a gaseous product (producer gas or syngas).

Socalled “allothermal” or indirect gasification is also possible.

The gasifier can either be of a “fixed bed”, “fluidised bed” or “entrained flow” configuration.

The resulting gas is a mixture of carbon monoxide, water, CO2, char, tar and hydrogen, and it can be used in combustion engines, micro-turbines, fuel cells or gas turbines.

When used in turbines and fuel cells, higher electrical efficiencies can be achieved than those achieved in a steam turbine.

it is possible to co-fire a power plant either directly (i.e. biomass and coal are gasified together) or indirectly (i.e. gasifying coal and biomass separately for use in gas turbines).

3) Pyrolsis Pyrolsis is a subset of gasification systems.

in pyrolysis, the partial combustion is stopped at a lower temperature (450°C to 600°C), resulting in the creation of a liquid bio-oil, as well as gaseous and solid products.

The pyrolysis oil can then be used as a fuel to generate electricity.

2 - Bio-Chemical Process Anaerobic Digestion anaerobic digestion is a process which takes place in almost any biological material that is decomposing and is favored by warm, wet and airless conditions.

The resulting gas consists mainly of methane and carbon dioxide and is referred to as biogas.

The biogas can be used, after clean-up, in internal combustion engines, micro-turbines, gas turbines, fuel cells and stirling engines or it can be upgraded to biomethane for distribution.
