Fuel distribution devices for use with burners are described herein. One embodiment of a fuel distribution device for a burner can include an inlet end having a disc-like annular cover with inlet openings, an outlet end having a disc-like annular support plate with groups of distribution openings, and cylindrical inner and outer walls. These components can define a distribution channel and the device can further include fuel feeding tubes extending from the inlet openings into the distribution channel, and each of the fuel feeding tubes can divide into branch pipes extending through the distribution channel to the annular support plate. Moreover, the branch pipes extending from a same feeding tube can be in communication with distribution openings within a same group, and the branch pipes can be coiled spirally about the inner wall and connected to distribution openings at an inclined angle such fuel ejected therefrom has a tangential velocity.

Fuel distribution device and a burner

The present invention is directed to a flame detection device comprising a flame signal receiver (), a flame signal passage () and a flame signal transmitting mechanism, characterized in that, the flame signal passage () passes through a furnace shell () into inner of the furnace and comprises an outside-furnace passage portion () and an inside-furnace passage portion (); wherein a pressure-resistant optical mechanism () is arranged at the outermost end of the outside-furnace passage portion, said pressure-resistant optical mechanism hermetically and transparently separate the flame signal receiver from the flame signal passage; and wherein the inside-furnace passage portion () is provided with a cooling mechanism (). Such a flame detection device is to be arranged on a furnace shell, and it could not only conduct a flame detection on the furnace under high temperature and high pressure, but also has a selection of the proper flame signal receivers installed for different stages of operation as desired.

Flame detection device

A gasification apparatus for solid fuel, especially an apparatus for producing syngas by pressurized gasification of coal powder, including a gasification chamber (II) and a syngas cooling and purification chamber (III). The inner wall of the gasification chamber is a water-cooling wall (). The inner side of the water-cooled wall is evenly coated with a layer of fire-resistant material (). There is an annular cavity between the water-cooling wall of the gasification chamber and the furnace body. A syngas quencher, a vertical pipe (), a gas distribution device (), a defoaming device, and a dewatering and deashing device () are provided in the syngas cooling and purification chamber. The apparatus has a simple structure and is easy to operate. A high temperature gasification method for dry powder of carbonaceous material comprises spraying the combustible material and oxygen into the furnace and followed by ignition.
