Abstract
Gasifiers, gasification systems, and methods for producing synthesis gas are disclosed. A gasifier can include a gasifier body. A feeder can be positioned to feed an organic material into the gasifier body. A pulse detonation burner can be located under or above the gasifier body and connected to the gasifier body to direct supersonic shockwaves upward into the gasifier body to heat the organic material and to form a jet spouted bed of the organic material or to operate as an entrained flow reactor. An outlet can be located at the gasifier body to allow removal of synthesis gas, residual ash, and other reaction products.
Claims22
A pulsed detonation shockwave gasifier comprising:
- a gasifier body;
- a feeder positioned to feed an organic material into the gasifier body;
- a pulse detonation burner located either:
- under the gasifier body and connected to the gasifier body to direct supersonic shockwaves upward into the gasifier body to heat the organic material and to form a jet spouted bed of the organic material or above the gasifier body and connected to the gasifier body to direct supersonic shockwaves downward into the gasifier body to heat the organic material as an entrained flow reactor;
- and
- an outlet connected to the gasifier body.
A method of producing synthesis gas, comprising:
- introducing an organic material into a gasifier comprising a gasifier body and a pulse detonation burner connected to the gasifier body;
- firing supersonic shockwaves from the pulse detonation burner into the gasifier body to heat the organic material using a detonation fuel including a mixture of a hydrocarbon fuel with oxygen-enriched air;
- and
- removing synthesis gas and residual ash from the gasifier through an outlet located at an upper portion of the gasifier body.
