Abstract

A method for using a downdraft gasifier comprising a housing and a refractory stack contained within the housing. The refractory stack may comprise various sections. Apertures in the sections may be aligned to form multiple columnar cavities. Each columnar cavity may comprise an individual oxidation zone. The method of use may include the steps of placing a feedstock into an upper portion of the refractory stack, measuring the temperature of each columnar cavity, and adjusting the flow of oxygen to a particular columnar cavity to maintain the temperature of the particular columnar cavity within a particular range.

Description

RELATED APPLICATIONS

[0001] This application is a continuation of U.S. patent application Ser. No. 12 / 170,421 filed Jul. 9, 2008, which claims the benefit of co-pending U.S. Provisional Patent Application Ser. No. 60 / 948,950 filed Jul. 10, 2007. Both U.S. patent application Ser. No. 12 / 170,421 and U.S. Provisional Patent Application Ser. No. 60 / 948,950 are hereby incorporated by reference.BACKGROUND

[0002] 1. The Field of the Invention

[0003] This invention relates to fuel generation and, more particularly, to novel systems and methods for gasification of municipal solid waste and other feedstocks.

[0004] 2. The Background Art

[0005] Manufactured gas, or synthesis gas (syn-gas) as it is more often called today, comprises the unburned gasses (carbon monoxide and hydrogen gas) created by incomplete combustion of an organic raw material. Gasification (the process of generating manufactured gas) was discovered independently in both France and England. By 1850, gasification of coal had developed t...
