biomass gasification - SlideShare

26/2/2016 · Updraft fixed bed gasifier • Biomass feed moves downwards and gasifying agents move upward counter-current to biomass through the fixed bed of biomass • Ash is removed either as dry ash or as slag (slagging gasifiers - temperatures are greater than the ash fusion temperature) • Has well defined drying, pyrolysis, reduction and combustion zones • Excessive tar in the product gas

Updraft Fixed Bed Biomass Gasifier Nigeria-Haiqi Biomass Burner

Updraft Fixed Bed Biomass Gasifier Nigeria . BIOMASS GASIFIER SERIES PRODUCTS Waste Gasification Power Plant Waste gasification power plant: capacity from 1000kw to 6000kw, modular design, several modular for big capacity.

Fixed-bed gasifiers for Biomass Gasification- Energy Alternatives

The fixed bed gasifier has a bed of solid fuel particles through which the gasifying media and gas move either up or down. It is the simplest type of gasifier consisting of usually a cylindrical space for fuel feeding unit, an ash removal unit and a gas exit. In the fixed bed gasifier, the fuel bed moves slowly down the reactor as the gasification occurs. The fixed bed gasifiers are of simple

Modeling product distribution of top-lit updraft gasification

Top-lit updraft (TLUD) biomass gasifiers produce relatively high yields of biochar when compared to other gasification units such as fluidized bed, downdraft, and updraft gasifiers (Nsamba et al. 2014). A top-lit updraft gasifier is a batch gasifier that is known to be ignited on the top layer of the biomass. Because of the flow of the biomass and the gasifying agent, it is also known as an

Powermax UFBG(Updraft Fixed Bed Biomass Gasifier)-Biomass
