Abstract
The utility model relates to a domestic dual-purpose coal-burning stove core which forms a conical shape and is characterized in that the inner wall of a stove core is provided with 3-6 rectangle grooves (1) so as to enlarge the flux of hot air, and the briquette and the broken coal can combust sufficiently.
Description
One, technical field:
The utility model relates to a kind of dual-purpose coal-fired combustion chamber, belongs to residential coal combustion stove and accessory production technical field.
Two, background technology:
The inboard wall of burner hearth of the combustion chamber of existing residential coal combustion stove and accessory all has corrugated little garden arc groove, combustion efficiency is better when using moulded coal, when using lump coal and disintegrating slag coal, the combustion chamber internal combustion is insufficient, thereby influence the thermal efficiency of whole stove, defective at existing combustion chamber has designed above-mentioned dual-purpose coal-fired combustion chamber.
Three, summary of the invention:
Dual-purpose coal-fired combustion chamber described in the utility model, the contour structures of combustion chamber is a cone shape, it is to be provided with 3 to 6 rectangular recess at the combustion chamber inwall, and it is consistent with the tapering of combustion chamber, above big below little, the end, top of rectangular groove communicates with the combustion chamber actinal surface, and the rectangular recess lower end communicates with the combustion chamber bottom surface.
Adopting the beneficial effect of the taper square groove that this structure is provided with is to have increased hot blast rate, can make fully burning of moulded coal (as honeycomb briquette), the fragment coal is fully burnt reach province's coal to economize on coal, and improves the purpose of the thermal efficiency.
Four, description of drawings:
Accompanying drawing 1 is dual-purpose coal furnace cored structure schematic diagram.
Wherein: 1-rectangular recess, 2-combustion chamber bottom surface, 3-combustion chamber actinal surface.
Five, the specific embodiment:
Dual-purpose coal-fired combustion chamber described in the utility model, its profile is a cone, and the lower end and the combustion chamber bottom surface 2 that are provided with 4 Baltimore grooves 1, Baltimore groove at the combustion chamber inwall are groove, and the top of groove does not communicate with combustion chamber actinal surface 3.
Claims (1)
