CONTINUOUS FLOW GAS GENERATOR

摘要

This invention was developed to improve the capacity and efficiency of a burner type that can not be classified as either a blast furnace or a pyrolytic oven. The blast furnaces usually have a greater capacity but their efficiency from an environmental standpoint is so poor that many have been shut down. The pyrolitic ovens performmore efficiently but their capacity is limited making them both uneconomical andproducers of problem by - products. The most efficient performer of the various types of burners are those with oxygen starved primary chambers that convert solids to gases to be burned in an after burner. This better system, however needs more capacity per hour to be economical. Increasing its capacity without the addition of this invention will result in higher particulates and SO2 emissions than the regulations allow. This invention resolves these problems by using a variable speed round rotating cone shaped burner floor designed especially for oxygen starved units that injects feedstock continuously with a variable speed auger on to the revolving cone shaped floor that has a series of steps the number depending on the size of the unit. This exposes the solids to the heat and speeds up the gasification process. The increase in gas production necessitated inventing a better afterburner with an improved gas/air mixing capability, with a longer retention time to assure complete burning of combustible particulates and with a better capability to destroy other undesirable elements in a high temperature up to 2400.degree.
