It described a design called the "stratified downdraft gasifier" which solves several drawbacks of earlier types. The European Union sponsored a wood gas project in Güssing, Austria, starting in 2005. This project was an electric power plant with a wood gas generator and a gas engine to convert the wood gas into 2 MW electric power and 4.5 MW heat
Staged gasifiers, where pyrolysis and gasification occur separately instead of in the same reaction zone as was the case in the World War II gasifiers, can be engineered to produce essentially tar-free gas (less than 1 mg/m 3), while single-reactor fluidized bed gasifiers may exceed 50,000 mg/m³ tar. The fluidized bed reactors have the ...
Since 2008 in Svenljunga, Sweden, a biomass gasification plant generates up to 14 MW th, supplying industries and citizens of Svenljunga with process steam and district heating, respectively. The gasifier uses biomass fuels such as CCA or creosote impregnated waste wood and other kinds of recycled wood to produces syngas that is combusted on site.
Biomass (in the context of energy generation) is matter from recently living (but now dead) organisms which is used for bioenergy production. There are variations in how such biomass for energy is defined, e.g. only from plants, [7] or from plants and algae, [8] or from plants and animals. [9]
Biomass heating plant in Austria; the heat power is about 1000 kW Fully automatic 140 kW wood chip heating system in Austria. 35 years old. There are four main types of heating systems that use biomass to heat a boiler. The types of biomass heating are fully automated, semi-automated, pellet-fired, and combined heat and power.
However they continued to curate and make available early designs and technical information about gasification and gasifier engineering. [2] In late 2016, their principal product was a 25 kW Power Pallet biomass genset which included formerly optional combined heat and power (CHP) and Grid-tied Electrical System features as standard equipment.

Down draft or cross draft gasification stoves, i.e. Dunsley Yorkshire, Welkom 600, Avalon Arbor™ wood stove, XEOOS. [18] Boiler stoves provide hot water as well as space heating. A backboiler can be an optional insert added to the back of the firebox, or a wrap-around water jacket that is an integral to the stove's structure.
This process is first used at the Gussing power plant in Austria [12] based on the steam gasification of biomass in the internally circulating fluidized bed. In the gasification process, fuel will be gasified at 850 °C [ 12 ] in the presence of steam to produce a nitrogen -free and clean synthetic gas.
