The present invention relates to a gasification burner comprising a main burner, N-stage sub-burners arranged on the inner side of the main burner, where N is an integer greater than or equal to 1, the main burner and each stage of the sub-burners have independent fuel channels and oxidant channels respectively, the main burner and each stage of the sub-burners are arranged in a coaxial sleeves from outside to inside; the inner diameter of the main burner is larger than the outer diameter of the first stage of the sub-burners, and the inner diameter of each stage of the sub-burners is larger than the outer diameter of its next stage of the sub-burners; the gasification burner can ensure fuels and oxidants to be mixed fully and evenly in limited reaction space and residence time, accelerate combustion reaction rate, thereby improving fuel conversion rate and gasification performance; meanwhile, it can flexibly adjust flame shape without reducing the load of gasifier furnace by adjusting the load of the main burner and each stage of the sub-burners, thereby effectively avoiding overheating of the gasifier furnace to meet different production load requirements of project sites.

Gasification burner

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.
