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.
Claims18
A pulsed detonation shockwave gasifier comprising:
- a gasifier body comprising an inlet;
- a feeder positioned to feed an organic material into the gasifier body;
- a first pulse detonation burner comprising a discharge zone, wherein the discharge zone is connected to the inlet of the gasifier body, where the first pulse detonation burner is configured to produce a hot gas and discharge the hot gas from the discharge zone into the inlet of the gasifier body, wherein the first pulse detonation burner is located either:
- under the gasifier body and connected to the inlet of the gasifier body to direct the hot gas and supersonic shockwaves upward into the gasifier body to heat the organic material and to form a jet spouted bed of the organic material, wherein the hot gas mixes with the organic material to form the jet spouted bed, or
- above the gasifier body and connected to the inlet of the gasifier body to direct the hot gas and 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 reformer connected to the outlet of the gasifier to receive synthesis gas and residual ash from the gasifier, wherein the reformer comprises:
- a reformer body,
- a second pulse detonation burner located either above or below the reformer body and connected to the reformer body to direct supersonic shockwaves downward or upward into the reformer body to heat the synthesis gas and residual ash.
