Abstract

A direct current burning furnace, comprising a furnace body with one end enclosed, a fuel burning cavity in the middle of the furnace, a fuel entry at the side wall of the furnace, a circular slot in the inner wall of the furnace, an ignition rod arranged on the bottom of the burning cavity, and a vent opened on side wall of the furnace. The utility model is simple in structure, not only can take diesel as fuel but also can take alcohol group and kerosene as fuel, meanwhile the circular slot of the side wall and the ignition rod in the middle are capable of keeping the shape and the position stability of the flame, and the flame may stay longer time in the burning cavity, the blending of fuel and air is more sufficient and the thermal efficiency is high. The utility model may be improved on basis of the existing diesel direct current furnace, with low manufacturing cost and extensive application.

Description

A direct-flow combustion furnace

technical field

The utility model relates to a stove, in particular to a direct-current combustion furnace suitable for various fuels.

Background technique

Liquid fuels such as alcohol-based fuels, kerosene and diesel are widely used in people's lives, especially in the catering industry. Various forms of burners and furnaces, due to the different properties of various fuels, use different fuels. The structure of the burner is different, and the same burner and burner can only use one kind of fuel.

There is a diesel direct current furnace in the prior art. The furnace body is in the shape of a top hat, the middle of the furnace body is a fuel combustion chamber, and the side wall of the furnace body is provided with a fuel inlet. When in use, the atomized diesel oil enters the combustion chamber in the middle through the fuel inlet and is then ignited. This type of stove flame stays in the combustion chamber for a short time, is not sufficiently mixed with air, has low thermal efficiency, and wastes more fuel; moreover, this type of stove is not suitable for other gaseous fuels.

Utility model content

The technical problem to be solved by the utility model is to provide a direct current combustion furnace suitable for various fuels.

According to above-mentioned technical requirement, the utility model adopts following technical scheme to realize:

A direct-flow combustion furnace comprises a furnace body with one end closed, a fuel combustion chamber in the middle of the furnace body, a fuel inlet on the side wall of the furnace body, and an annular groove on the inner wall of the furnace body.

As an improvement to the above solution, the annular groove is a continuous threaded groove or a plurality of mutually independent grooves.

A fire guide column is also arranged at the bottom of the combustion chamber.

In order to improve the combustion effect, ventilation holes are also opened on the side wall of the furnace body.

The utility model has a simple structure, which can use diesel oil as fuel, alcohol base and kerosene as fuel. At the same time, the annular groove on the side wall and the fire guide post in the middle can keep the shape and position of the flame stable, and can make the flame burn continuously. The residence time in the cavity is longer, the fuel and air are mixed more fully, and the thermal efficiency is high; the utility model can be directly improved on the basis of the existing diesel direct current furnace, and the manufacturing cost is low, which is suitable for wide application.

Description of drawings

Accompanying drawing 1 is the structural diagram of the embodiment of the utility model; Accompanying drawing 2 is the schematic diagram of the use state of this embodiment.

Detailed ways

In order to facilitate the understanding of those skilled in the art, the structural principle of the utility model will be further described in detail below in conjunction with specific embodiments and accompanying drawings:

As shown in Figure 1, a specific implementation of the utility model is disclosed. It is a hat-shaped furnace body 1 as a whole, with a fuel combustion chamber 12 in the middle of the furnace body 1 and a fuel inlet 2 on the side wall of the furnace body 1 . Fuel can enter the combustion chamber 12 from the fuel inlet 2 for combustion.

A fire guide post 3 is fixed at the bottom of the combustion chamber 12, and a plurality of ventilation holes 11 are provided on the side wall of the combustion chamber 12. Meanwhile, a spiral annular groove 4 is also provided on the inner wall of the combustion chamber 12.

After the atomized fuel or vaporized fuel enters the combustion chamber 12 from the fuel inlet 2, the fuel flows outward along the spiral annular groove 4 while burning in the combustion chamber 12, thereby forming a spiral flame, which effectively increases the flame in the combustion chamber. The residence time in the combustion chamber and the guidance of the fuse column 3 make the flame more stable and concentrated.

Claims (4)

1. a straight flow combustion stove comprises the body of heater (1) that an end seals, and is fuel combustion chamber (12) in the middle of the body of heater, and sidewall of the furnace body has fuel inlet (2), it is characterized in that: also have cannelure (4) on inboard wall of furnace body.

2. straight flow combustion stove according to claim 1 is characterized in that: described cannelure is continuous thread groove or a plurality of conduit independently mutually.

3. straight flow combustion stove according to claim 1 and 2 is characterized in that: also be provided with one in the combustion chamber bottom and lead the column of flame (3).

4. straight flow combustion stove according to claim 3 is characterized in that: also have air vent (11) at sidewall of the furnace body.
