Description
Technical Field
[0001] This utility model relates to an improved energy-saving combustion furnace core, belonging to the field of combustion furnace accessories. Background Technology
[0002] A compression combustion furnace is a type of tubular furnace. It uses a fan to blow air into the combustion chamber, ignites the fuel using an igniter, and rapidly propels the flame outwards under the force of the air. For example, in Chinese utility model patent CN208936148U, entitled "A Furnace Core for Complete Combustion," the applicant discloses a furnace core for complete combustion, comprising a core body and a flame distribution frame disposed within the core body. The core body includes a sealed section, a middle section, and an open section, arranged in a stepped manner from bottom to top, each with a hollow inner cavity. The hollow inner cavities of the sealed section, the middle section, and the open section together form the combustion chamber of the core body. The flame distribution frame is mounted on the open section. The outer diameter of the sealed section of the core body... The outer diameter of the sealed section of the furnace core body is smaller than that of the middle section. The inner diameter of the sealed section is smaller than that of the middle section, and a first annular step is formed between the inner walls of the sealed section and the middle section. The outer diameter of the middle section of the furnace core body is smaller than that of the open section. The inner diameter of the middle section of the furnace core body is smaller than that of the open section, and a second annular step is formed between the inner walls of the middle section and the open section. Multiple vertically distributed air holes are provided on the first annular step. The bottom of the sealed section is the sealed end. A through hole for atomized fuel and air is provided on the sealed end. Multiple air holes are also provided on the sealed end, which are vertically distributed around the through hole.
[0003] While the furnace core of the aforementioned patent can, to a certain extent, make fuel atomization and combustion more complete, thus achieving energy saving and consumption reduction, its combustion efficiency still needs further optimization and improvement.
[0004] Based on the above issues, the applicant conducted research, which led to this case. Utility Model Content
[0005] The purpose of this utility model is to provide an improved energy-saving combustion furnace core that can enhance combustion efficiency and has a simple structure.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An improved energy-saving combustion furnace core includes a core body, which has a first furnace section and a second furnace section located above the first furnace section. The inner diameter of the first furnace section is smaller than that of the second furnace section. The lower end of the first furnace section is provided with a cap, which has a central hole and first air-aiding holes arranged around the central hole. The upper end of the second furnace section is provided with a flame-dividing cap. The furnace core also includes a vaporization cap, which is disposed in the inner cavity of the second furnace section and divides the inner cavity of the second furnace section into a first chamber and a second chamber located above the first chamber. The first furnace section has an installation hole for an ignition needle to pass through it, or the second furnace section has an installation hole for an ignition needle to pass through the first chamber. The vaporization cap has a plurality of first flame-dividing through holes, which extend from the upper end face to the lower end face of the vaporization cap. The plurality of first flame-dividing through holes are arranged around the central axis of the vaporization cap.
[0008] As a preferred embodiment of this utility model, the number of the first flame-dividing through holes is 2 to 20, and the plurality of the first flame-dividing through holes are evenly arranged around the central axis of the vaporization cover and form a circle.
[0009] In a preferred embodiment of this invention, the mounting hole is disposed on the second furnace section.
[0010] In a preferred embodiment of this utility model, the second furnace section is provided with a second air-supporting hole corresponding to the first chamber, and the second air-supporting hole is arranged obliquely upward.
[0011] In a preferred embodiment of this utility model, the inner wall of the second furnace section is provided with a first mounting platform, and the periphery of the gasification cover is mounted on the first mounting platform.
[0012] In a preferred embodiment of this invention, the vaporization cap is flat.
[0013] As a preferred embodiment of the present invention, the flame distribution cover includes a disc body and a flame guide tube disposed at the upper end of the disc body. The disc body is also provided with a plurality of second flame distribution holes, which are evenly distributed around the flame guide tube.
[0014] In a preferred embodiment of this invention, the upper end of the first furnace section and the lower end of the second furnace section are connected by a connecting platform.
[0015] As a preferred embodiment of this utility model, a support platform is provided at the lower end of the first furnace section, and the cover is detachably mounted on the support platform.
[0016] In a preferred embodiment of this utility model, an installation cylinder is fitted onto the lower end of the second furnace section. The upper end of the installation cylinder is open and fixed to the second furnace section. The lower end of the installation cylinder is closed and has a guide hole for the oil nozzle to pass through. Multiple heat dissipation holes are provided around the guide hole. An air control chamber is formed between the cover and the lower end of the installation cylinder.
[0017] In the preferred embodiment of this invention, the inner diameter of the first furnace section is smaller than that of the second furnace section. This reduces the atomization resistance of the liquid fuel moving upwards from the first furnace section to the second furnace section, improving the atomization effect. The inner cavity of the second furnace section is divided into a first chamber and a second chamber located above the first chamber. This compresses the ignition and combustion space of the second furnace section, resulting in a stronger flame after it bursts out from the first ignition orifice. The flame then diffuses and undergoes secondary vaporization in the second chamber, leading to more complete fuel combustion. This invention has the advantage of simple structure. The removable design of the cap, vaporization cap, and detachable cap facilitates cleaning and maintenance, improving combustion efficiency. Preferably, the ignition needle is placed in the first chamber, and a first air-assisted orifice is provided in the first chamber. The liquid fuel entering the second furnace section from the first furnace section is more fully atomized before ignition, and the air-assisted orifice pushes the flame towards the first ignition orifice, improving combustion efficiency.

The first chamber 13 and the second chamber 14 have approximately the same volume, that is, the vaporization cover 30 is generally located in the middle of the second furnace section 12. The first furnace section 11 is provided with a mounting hole 17 for the ignition needle 70 to pass through the first furnace section 11, or the second furnace section 12 is provided with a mounting hole for the ignition needle 70 to pass through the first chamber 13.

The air blown out from the first air aid hole 22 further disperses the oil mist sprayed from the oil injector. The atomized oil moves upward to the first chamber 13 for further atomization and dispersion. It is ignited by the ignition needle 70. The burning flame enters the second chamber 14 from the first flame distribution hole 31 of the gasification cover 30.
