Abstract

A pulse detonation device is provided for delivering a shock wave into a gasification device to promote a localized coal gasification reaction in the gasification device. The pulse detonation device includes a fuel inlet for receiving fuel, an air inlet for receiving air, a pulse detonation chamber wherein the fuel and air are configured to mix, and an ignition device for igniting the mixture of fuel and air. The ignition of the mixture of fuel and air creates a shock wave in the pulse detonation chamber. Further, the pulse detonation chamber is attached to a gasification chamber and is configured to extend into a coal feed tube that extends into the gasification chamber, with the shock wave configured to exit the pulse detonation chamber and interact with coal in the coal feed tube.

Description

technical field [0001] The present invention relates to gasification devices for gasifying coal, and more particularly to pulse detonation devices for delivering high temperature and pressure pulse waves to gasify coal within a coal feed pipe. Background technique [0002] The gasification process can be used to convert carbon-based materials, such as coal, into a gas mixture that can be used as fuel. The gasification process may take place in a gasification unit. Gasification devices may include moving bed gasifiers, fluidized bed gasifiers, entrained flow gasifiers, slagging gasifiers, and the like. A combination of high temperature, pressure, and controlled amounts of oxygen and / or steam can be used to act with the coal to produce the desired gas mixture. However, there may be a limited amount of oxygen available in the gasification chamber to react with the coal during the gasification stage. Furthermore, sufficiently high temperatures and pressures may be difficult t...
