Fixed Bed Gasifiers - an overview | ScienceDirect Topics

There are three types of fixed bed gasifiers, as shown in Fig. 16.5: updraft (counter-current), downdraft (co-current), and cross draft gasifier. In case of the updraft gasifier, the fuel is supplied at the top and the air at the bottom so that fuel moves against the air flow, while in the case of the downdraft, air is introduced above the oxidation zone and the product gas is removed from the

[PDF] CFD researched on rice husk gasification in a pilot fixed

30/9/2016 · Rice husk, an abundant biomass in Viet Nam, was used to partially replace fossil fuels by gasification process. The study was conducted on the pilot plant fixed bed up-draft gasifier with two kind of gasification agents, pure air and air-steam mixture. Mathematical modeling and computer simulations were also used to describe and optimize the gasification proceshaiqi. Mathematical modeling was

Updraft Fixed Bed Gasification haiqi Model (Software) -

27/9/2007 · The fixed bed model is constructed using haiqi, process modeling software, coupled with a FORTRAN user kinetic subroutine. Current updraft gasification models created in haiqi have limited predictive capabilities and must be "tuned" to reflect a generalized gas composition as specified in literature or by the gasifier manufacturer

Improved Gasification of Rice Husks for Optimized Biochar -...

Rice husk (RH) waste, an abundant agricultural by-product, was gasified in a top-lit updraft haiqi rice husk gasifier with a biochar yield of 29.0% ± 1.9%. The equivalence ratio (ER) for optimum biochar production was identified and its effect on biochar properties such as pH, volatile matter (VM), fixed carbon (FC) and ash content (AC
