Abstract
A coal gasifying burner characterized by a rotating grill which is composed of grill disks arranged on two pipes with a narrow gap between the grills and which rotates very slowly inwards when viewed from the top sloped side walls made of metal sheet having a sloper compatible with coal flow, a cylindrical jacket placed around the periphery of the nozzle which delivers combustion air to the burner, gasification of a quantity of coal located on the sloping side walls around a narrow area where coal combustion takes place, and combustion of the generated coal gas outside of the burner by secondary air which cools the system and gets heated itself by the coal cooking process.
Claims7
A coal gasifying burner comprising a coal storage, a combustion cell positioned beneath said coal storage, narrow gap means with rounded edges through which coal flows continuously from said coal storage to said combustion cell, a roof for said combustion cell separating said combustion cell from said coal storage, an air bearing insulation partition placed on said roof for separating the coal in said coal storage from said roof, sloping side walls made of sheet metal having slopes compatible with coal flow, a nozzle for burning coal gas generated by burning coal in said combustion cell, a jacket surrounding said nozzle, and secondary air means connected to said jacket for cooling said roof and for supporting combustion of coal gas at said burner, whereby gasification is obtained of an abundance of coal located on said sloping side wall around a narrow area where coal combustion takes place, and combustion of the generated gas outside of the burner at said nozzle by secondary air which previously cooled the roof and thus gets heated itself by the cooling process.
