Embodiment 1

[0028] The novel swiss roll micro-burner cassette furnace of this embodiment is mainly composed of combustion chamber 4, fuel pipeline control electronic valve 6, fuel gas storage cylinder 7, rotating parabolic heat collecting mirror 8 and other main structures. Combustion chamber 4 is placed on support 5, and combustion chamber 4 is made of 5 micro burners, and fuel gas cylinder 7 draws 2 copper pipes and links to each other with fuel pipeline control electronic valve 6, is controlled the opening and closing of pipeline by pipeline control electronic valve. Of the 2 copper pipes drawn out, one is connected to the entrance of the combustion chamber ①, and the other is connected to the entrance of the other combustion chamber ② with 4 branch pipes. The micro-combustor is designed as a swirling channel with a rectangular cross-section, which increases convective heat transfer and preheats the reactants. The difference in the entire combustion room temperature is small, and the co...

Embodiment 2

[0034] In this embodiment, other structures are the same as in Embodiment 1, except that the square rotary micro-burner is changed into a circular rotary micro-burner.

[0035] Figure 7 It is the front view of the circular rotary swiss roll micro burner of the present invention. Its basic structure is similar to that of a square rotary swiss roll structure micro-burner, where A is the combustion chamber inlet of a cylindrical boss with a diameter of 8mm, and place B is the combustion chamber outlet of a cylindrical boss with a diameter of 8mm. The channel section of the circular swirling swiss roll micro burner is a rectangle of 10×3 mm, the inner diameter of the spiral channel is 10 mm, and the outer diameter is 80 mm.

Abstract

The invention belongs to the field of advanced combustion techniques, and particularly relates to a novel portable gas stove based on a Swiss roll structure micro-combustor. According to the portable gas stove, an ordinary portable gas stove is improved and designed on the basis of the micro-combustion principle; the portable gas stove comprises a combustion chamber, a bracket and a fuel storage bottle, wherein a fuel pipeline is used for controlling an electronic valve; square rotary micro-combustors or round rotary micro-combustors are distributed in the combustion chamber in a matrix; and the micro-combustors are designed into rotary channels with rectangular sections, so that convection heat transfer is increased; reactants are preheated; the overall combustion chamber is relatively small in temperature difference; combustion is full; the quenching phenomenon of the micro-combustion chamber is prevented; by virtue of a rotating parabolic heat mirror arranged between the bracket and the combustion chamber, the heat loss on the lower part of the combustion chamber can be reduced; and the bottom of the upper pot is relatively efficiently heated. The novel portable gas stove provided by the invention is high in energy density, long in function time and small in heat loss; energy resources can be saved; and emission can be effectively reduced.

Description

technical field [0001] The invention belongs to the application field of advanced combustion technology, and in particular relates to a novel cassette furnace based on a micro-burner with a Swiss roll structure. Background technique [0002] Cassette stove is also called portable butane gas stove; it refers to non-fixed cooking and kitchen utensils that use filled butane gas or liquefied petroleum gas as fuel, oxidize with air to generate heat and are used to heat dishes, etc., and are mostly used for outdoor leisure at home and hotel supplies. [0003] The patent application number is CN99114547.X: a new type of liquid fuel stove that can replace the cassette furnace. The combustion chamber is equipped with a fire gathering wall and a combustion support wall. The bottom of the combustion chamber is designed as a U-shaped groove. There is a temperature difference throughout the combustion chamber, and the combustion is not complete. [0004] Micro-scale combustion is propo...
