Oxygen or air both can be used as the gasifying agent, but most of the commercial plants use oxygen as the gasifying agent. Here, the velocity of gasifying agent is even higher than in circulating fluidized bed gasifier. The small fuel particles are entrained by the gasifying agent, and they flow through the gasifier in a dense cloud.
Among the gasifier types, downdraft gasifiers are suitable for small-scale power generation applications considering their high quality syngas production with lower particle and tar content [3]. One of the parameters showing high syngas quality is H 2 /CO ratio, and when this ratio is low in syngas, the conversion efficiency to target product ...
In the assessment of the GoBiGas gasifier, one of the main unknowns is the heat losses Q l,tot, which in the GoBiGas plant are considerable because of its relatively small size. The ratio of the heat losses between the combustor Q l,comb and the gasifier Q l,gasif was previously estimated to be 3 42, based on the external surface and the ...

demonstration at the McNeil wood-fired power plant—and the Future Energy Resources Corporation (FERCO), a private firm committed to developing the gasifier for its commercial potential. The Vermont project is demonstrating low-pressure, indirect gasification of bio-mass. The gasifier operates by heating wood chips to about 830°C (1526°F) in hot
Relevant market-ready small-scale gasification systems are analyzed under this lens, leading to an analysis of the reactor and filtration design. To help understand the economical sustainability of these plants, an analysis of the influence of capital expenditures and operating expenditures on the return of investment is included in the …
Despite these features, small scale applications struggle to succeed as a leading solution for sustainable development. The aim of this review is to investigate the existing …
The Mitsubishi Heavy Industries (MHI) gasification technology was developed with the goal to maximize the gasifier efficiency (e.g., dry feed, and a unique two-stage reactor design) and reduce costs (e.g., air-blown to eliminate power consumption and capital cost of an oxygen plant).The development commenced in the early 1980s under a joint venture …
In Finland, an air-blown updraft gasifier with a product name Bioneer was developed in the early 1980s, and since then several commercial plants have been built and operated at small district heating boilers and drying kilns . Thermal cracking of updraft gas was tested at the pilot scale in the late 1980s to produce a gas that could be …
