Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
177 words
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.
Claim 2
Dependent Claim
177 words
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.
Claim 3
Dependent Claim
76 words
The coal gasifying burner of claim 1 further comprising a grill assembly at the bottom of said combustion cell which includes a plurality of grill disks arranged on two pipes with a narrow gap between the opposed disks of each pipe, said disks being rotatable very slowly inwardly when viewed from the top for maintaining a continuous and same quality combustion in said combustion cell, and comb means for cleaning slag from between the grill disks.
Claim 4
Dependent Claim
18 words
The coal gasifying burner of claim 2 wherein each disk has in each side thereof an annular groove.
Claim 5
Dependent Claim
23 words
The coal gasifying burner of claim 2 wherein said comb means comprises a plurality of combs fitted between adjacent disks of each pipe.
Claim 6
Dependent Claim
24 words
The coal gasifying burner of claim 2 wherein said narrow gap means is formed between said roof and said sidewalls of said combustion cell.
Claim 7
Dependent Claim
15 words
The coal gasifying burner of claim 2 further comprising cooling means for said sloping sidewalls.
Claim 8
Dependent Claim
42 words
The coal gasifying burner of claim 2 further comprising a fluid filled ash tray of siphon shape for receipt of ash and slag from said grill assembly and removal of ash and slag from said ash tray through the siphon leg thereof.
