OptiGas - Air / Steam Blown Gasifier With Gas Turbine
Only gasification allows to convert solid biomass to reach high efficiency in combined heat and power generation in the decentralized sector. Due to this Seenova has developed an fluidized bed gasifier which was optimized and tested and ready for market entry.
Products Details
- Fluidized bed gasifier:
The biomass to be gasified is brought into a bubbling fluidized bed with very homogenous reaction conditions. - Water vapor as gasification agent:
Instead of air (autothermal gasifier) a mixre of air and steam is used as gasification agent. this provides an optimum quality of the produced gas.
OptiGas is a water vapor gasifier with fluidized bed technology connected to a gas turbine to produce combined heat and power. It is charged with biomass (e.g. wood chips) or waste material (e.g. dried sewage sludge).
This combination of gasifier with a gas turbine - i.e. 'a solid fuel fired gas turbine' - enables electrical efficiencies of power generation with biomass up to now not realized.
Increase of Efficiency
The direct coupling of the OptiGas gasifier with the gas turbine is increasing the overall efficiency (from the fuel to the generator) considerably. With this it is possible for the first time to convert biomass into electric power with an efficiency up to now only achievable with natural gas.
OptiGas - applications and product strategy
The thermal gasification of biomass - especially with water vapor as gasification agent - is considered a a key technology for future energy systems and biorefineries.
OptiGas enables the provision of popular products from biomass currently in demand, such as
- power and heat production by means of cogeneration
- provision of storable energy carriers, e.g. hydrogen
- conversion of the gas to substitute natural gas (SNG) or synthetic fuels (BTL - biomass to liquid)
Advantages
- decentralised und efficient
- low-maintenance
- fully automated operation
