Abstract
The utility model discloses a gas-fired fuel-economizing cover, which adopts the structure of a circular cone-shaped hollow ring (1). An inner cone surface is provided with equidirectional spiral convex ribs (2) and an air inlet (3). A ring is covered on the periphery of flame to support a heating container; meanwhile, the outer surface of the flame can be isolated from air, and the loss of the heat can be reduced; the flame has sufficient combustion time and combustion supporting air to reach the complete combustion; the combustion utilizing rate is high, and the energy-saving effect is obvious.
Description
The utility model provides a kind of energy-saving cover that is used for the combustion gas tool.
Traditional combustion gas tool, the flame of kitchen range ejection rises naturally, contact of flame top and heating container, flame outer surface then directly and air carry out heat exchange, make a large amount of heat-energy losses among air, cause thermal efficiency reduction, the raising of combustion gas expense.
The purpose of this utility model is that design is a kind of simple in structure, and the fuel gas energy-saving cover of making is fully collected flame heat regulating easily, makes it to reach completing combustion, improves the thermal efficiency.This purpose is reached by following technique measures: the characteristic of utilizing gas flame ejection nature to rise, have the truncated cone hollow ring of spiral convex rib and air admission hole by flame shape design one, and make flame outer surface and air insulated, reduce thermal loss; Pilot flame is the radial burning of trochoid spiral, prolongs the time of staying of flame in cover; Increase combustion air, make flame reach completing combustion, thereby improve the thermal efficiency.In conjunction with the accompanying drawings, be described in detail as follows: (seeing accompanying drawing)
Fig. 1 is the axial plane cutaway view of fuel gas energy-saving cover, and Fig. 2 is a vertical view.
The fuel gas energy-saving cover body is a truncated cone hollow ring (1), and ring covers in around the flame, the supporting heating container.End mouth and kitchen range form annular air admission hole, and suitable for reading and heating container forms annular venthole; Inner conical surface and flame outer surface are pressed close to, and make flame outer surface and air insulated, have significantly reduced thermal loss, help improving flame temperature in the cover; The characteristic of utilizing flame ejection nature to rise is provided with one group of equidirectional spiral convex rib (2) on inner conical surface, pilot flame is the radial burning of trochoid spiral, can prolong the time of staying of flame in cover, makes it to be fully burned; The air admission hole (3) of sufficient amount is set on the inner conical surface, utilizes siphonage, make flame obtain sufficient air-breathing and reach completing combustion; The axis of air admission hole and inner conical surface bus angle should be less than 90 °, and when the air admission hole axis was parallel with the cover body axis, manufacturability and siphon effect were best; Cover body can make conductive heat loss minimum as making with pottery or other flame-proof thermal insulation material, and efficiency of combustion is the highest.After tested, use this energy-saving cover, the combustion gas thermal efficiency can reach 65%, and than improving more than 35% without energy-saving cover, wide popularization and application can obtain remarkable economical, social benefit.
Claims (3)
1, a kind of fuel gas energy-saving cover is characterized in that: cover body is truncated cone hollow ring (1), and inner conical surface is provided with one group of equidirectional spiral convex rib (2).
2, fuel gas energy-saving cover as claimed in claim 1 is characterized in that: inner conical surface is provided with air admission hole (3).
3, as claim 1 or 2 described fuel gas energy-saving covers, it is characterized in that: the axis of air admission hole is parallel with the cover body axis on the inner conical surface.
