High efficiency cyclone gasifying combustion burner and method

摘要

A cyclone gasifying combustion burner and its operation is described. An exemplary burner has an inner cylindrical wall with a contour chamber feeding combustion air into the inner cylindrical wall, with an open end and a solid fuel support end where a combustible material forms a fuel bed. The inner cylindrical wall has a series of inclined air jet holes of substantially predetermined diameter and disposed at substantially predetermined locations therein to create a unidirectional cyclone within a combustion zone defined within the inner cylindrical wall. The air jet holes are disposed at a tangential and vertical angle whereby the combustion air is drawn into the inner cylindrical wall and creates a cyclone flow to mix with the combustion gases released from the flaming pyrolysis fuel bed and causes the combustion gases to flow in a cyclone path within a reaction zone to increase the residency, mixing and turbulence time of the combustion gases and simultaneously precipitate suspended particles against an inner surface of the inner cylindrical wall whereby the particles are caused to gravitate to the fuel bed where they are removed in a controlled manner during the operation of the burner.
