Improvements to the gasifier furnace design and process method to facilitate continuous production of mainly H.sub.2, CO and granulated solid from molten liquid or the liquid slag in the presence of carbonaceous material. It is a method of quenching molten liquid and cooling post quenched hot granulated solid which is done within a long horizontal reaction chamber space of the furnace in the presence of C and H.sub.2O. A moving layer of continuously gas cooled granulated solid protects the moving floor underneath by substantially reducing the possibility of heat transfer from the horizontal reaction chamber to such moving floor and its parts and preventing direct contact between the post quenched hot solid granulates and such moving floor. Such moving floor having plurality of gas passages and is disposed above a plenum that receives gas from outside source and uniformly distributes the gas to pass through all the gas passages.

A feedstock delivery system transfers a carbonaceous material, such as municipal solid waste, into a product gas generation system. The feedstock delivery system includes a splitter for splitting bulk carbonaceous material into a plurality of carbonaceous material streams. Each stream is processed using a weighing system for gauging the quantity of carbonaceous material, a densification system for forming plugs of carbonaceous material, a de-densification system for breaking up the plugs of carbonaceous material, and a gas and carbonaceous material mixing system for forming a carbonaceous material and gas mixture. A pressure of the mixing gas is reduced prior to mixing with the carbonaceous material, and the carbonaceous material to gas weight ratio is monitored. A transport assembly conveys the carbonaceous material and gas mixture to a first reactor where at least the carbonaceous material within the mixture is subject to thermochemical reactions to form the product gas.

The present invention includes a gasifier for gasifying fuels having a container with a top, sidewalls and a bottom for facilitating the gasifying process. One or more open vertical shafts extend downward inside the container for allowing a downdraft or updraft of air and fuel for the gasifying process. A rotating bed is preferably included inside the container and below the one or more shafts for receiving the fuel. The bed rotates essentially perpendicular to the shaft to facilitate even heating and gasifying of the fuel. The bed is further movable relative to the vertical shaft in order to increase or decrease the volume of fuel flow to the fuel.
