COMBUSTION CHAMBER HOUSING FOR EVAPORATING BURNER

摘要

FIELD: power engineering. ^ SUBSTANCE: housing of combustion chamber for evaporating burner comprises piping member whose first and second axial sections with respect to the longitudinal axis of the piping member are open for discharging combustion products and receiving the bottom unit, respectively. The piping member is made by casting. The second axial end section of the piping member has bearing collar on the inner side for permitting the bottom unit to abut against the collar in the axial direction. The bearing collar projects inward and is made of a step member provided on the piping member. The second axial end section has a hollow provided on the inner side of the piping member. The hollow receives the locking member that presses the bottom unit to the bearing collar and locking planks that are made in block with the piping member and bent radially inward or made for permitting bending of the locking planks. The second end section has several locking hollows. The piping member is provided with several openings for supplying air and igniting device. The first axial end section receives fire shield that embraces the outlet opening for combustion products. ^ EFFECT: simplified design. ^ 11 cl, 5 dwg
