1. A continuous system for gasification of a high ash biomass feedstock, wherein the high ash biomass feedstock comprises primarily farm wastes, comprising:
a reaction zone, the reaction zone configured to receive an ash-containing biomass feedstock and including a controllable system for introducing air into the ash-containing biomass feedstock to form a char, the air being introduced at a level less than that required for complete oxidation of the ash-containing biomass feedstock, the reaction zone including a live floor having multiple augers in a side by side configuration, wherein a speed of the multiple augers is controlled to control a rate that material in the reaction zone is transferred through the reaction zone;
a char cooling area, the char cooling area configured to receive the char from the reaction zone and having a gas capturing system for recovering gas released by the char in the char cooling area as the char cools, the char cooling area including at least one char removal auger, wherein the carbon content of the char is adjusted by varying one or more of a feed rate of the ash-containing biomass feedstock and air into the system; and
a controller configured to adjust dwell time of the ash-containing biomass feedstock in the reaction zone and the char cooling area, and maintain a continuous process.
