Abstract
A gasifier system for reducing the particle size of non-gas byproducts of the gasification process. The gasifier system generally includes a grinder that permits uninterrupted syngas flow during gasification of biomass that contains high amounts of silica and/or salts. The described system and method incorporates a grinder that breaks apart the resultant non-gas byproducts into finer particles that may be flushed out of a gasifier using the syngas stream. The particles may then be easily separated from the gas stream in a separator and collected in a char or waste bin for removal/disposal.
Claims19
A gasifier system, comprising:
- a gasifier for gasifying a biomass material, wherein the gasifier comprises an inlet and an outlet, wherein the inlet of the gasifier is adapted to receive the biomass material, wherein the outlet of the gasifier is adapted to output a flow of a syngas and a non-gas byproduct, wherein the non-gas byproduct has an initial particle size;
- and
- a grinder including an inlet and an outlet, wherein the inlet of the grinder is fluidly connected to the outlet of the gasifier for receiving the flow from the outlet of the gasifier, wherein the grinder is adapted for grinding the non-gas byproduct from the gasifier into a reduced particle size, wherein the outlet of the grinder is adapted to output a combined flow of the syngas and the non-gas byproduct having the reduced particle size, wherein the reduced particle size of the non-gas byproduct is smaller than the initial particle size of the non-gas byproduct.
A method of grinding non-gas byproducts from gasification, comprising:
- gasifying a biomass material within a gasifier to produce a flow of a syngas and a non-gas byproduct, wherein the non-gas byproduct has an initial particle size;
- transferring the flow of the syngas and the non-gas byproduct from the gasifier into an inlet of a grinder;
- grinding the non-gas byproduct into a reduced particle size by the grinder;
- and
- outputting a combined flow of the syngas and the non-gas byproduct having the reduced particle size from an outlet of the grinder, wherein the reduced particle size of the non-gas byproduct is smaller than the initial particle size of the non-gas byproduct.
