generates an off-gas that contains burnable gases (e.g., hydrogen and carbon <br />monoxide) that can be used off-site,it can bo classified aaagasifier. <br />1.2.1 Gasification <br />Gasification is the heating ofan organic waste (MSW) to produce a burnable gas <br />(approximately 85 percent hydrogen and carbon monoxide mb') for use off-site- <br />While pyrolysis systems are primarily focused on waste destruction, a gasifier is <br />designed primarily boproduoa usable gas. As shown inHgunaB-7,Thernose|ect,a European firm represented in the U.S. <br />by InterCity Waste Technologies of <br />Malvern, <br />PA, has developed a system composed of 4OOTPD modules processing M5V. <br />Waste <br />Figure B-7. Typical Gasification Systern9 <br />is fed into a gasification chamber to begin the heating process, after being <br />sufficient only to maintain the <br />cornpressedtonsrnoveentrapped air' Smrneoxygen, <br />eotad into t|' r�actor vvh�re <br />heat necessary for the process to proceed, |o /n] /e <br />temperatures in excess of3,OOO»Fare generated. At this high temperature, organic <br />materials in the y4SVV will dissociate into hydrogen, methane, carbon dioxide, water <br />vapor, etc and non-organics will melt and form a glass-like slag. After the gas is <br />cleaned, etc., and <br />removed, and the gas can be used for power generation, heating, <br />' ,," <br />or other purposes. Th e glass-like slag can be used as fill, or as a building material <br />for roads, etc. <br />A variation of the fluid bed incineration system described in this section is the <br />fluidized-bed gasifier, shown in Figure B-8. <br />eSource: International Waste Technologies, Malvern, PA. <br />GBB/C08027-01 B-10 August 15, 2008 <br />
