Abstract
Official abstract text for this publication.
An ignition torch that can easily be inspected regardless of the state inside a gasification furnace. The ignition torch ( 10 ) extends from an outside of a gasification furnace ( 1 ) to an inside of the gasification furnace ( 1 ) so as to receive feed of fuel and combustion air from one end positioned outside of the gasification furnace ( 1 ) and to feed flames to the other end positioned in the inside of the gasification furnace ( 1 ). An opening/closing valve ( 24 ) is provided downstream in a fuel flow direction from an ignition section ( 22 ) provided at the outside of the gasification furnace ( 1 ). A flame-holding section ( 28 ) is provided on the other end of the ignition torch ( 10 ). Supporting fuel is supplied to the flame-holding section ( 28 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A pressurized gasification furnace including an ignition torch extending from an outside of a gasification furnace to an inside of the gasification furnace which is pressurized during operation, the ignition torch comprising: a first end positioned outside of the gasification furnace; a second end positioned inside of the gasification furnace; an ignition device positioned outside of the gasification furnace; and an opening/closing valve located outside of the gasification furnace and disposed downstream in a fuel flow direction relative to the ignition device, wherein the entire ignition device is disposed upstream of the opening/closing valve in the fuel flow direction, wherein a fuel supply port and a combustion air supply port are provided at the first end of the ignition torch for receiving fuel and combustion air and feeding the fuel and the combustion air to the second end of the ignition torch positioned in the inside of the gasification furnace in order to make flames at the second end. 2. The pressurized gasification furnace according to claim 1 , wherein a flame-holding section is provided at the second end of the ignition torch, and an auxiliary fuel pipe is provided to supply auxiliary fuel to the flame-holding section.
