Embodiment 1

[0023] refer to figure 1 , figure 2 and image 3 , a diesel burner with high reliability and high power adjustment ratio, including outer wall 1, flame cup 2, beam flame ring 6, shell 8, base 9, rotor 4, oil pump 7, oil pipe 11, motor 12, motor support Frame 15, wind wheel 10, heat shield 13, igniter 3, fire detection sensor 5, oil drain pipe 14. The flame cup 2 opens upwards, the rotor 4 opens downwards, the rotor 4 is located in the flame cup 2, and the annular area between the flame cup 2 and the rotor 4 forms a combustion chamber; the motor 12 is arranged on the flame cup 2 through the motor support frame 15 Below, the rotor cup 4 and the wind wheel 10 are installed on the same output shaft of the motor 12, the rotor cup 4 is installed on the upper end of the output shaft of the motor 12, the wind wheel 10 is installed on the lower end of the output shaft of the motor 12, and the rotor 4 is used For atomized diesel oil, the wind wheel 10 is used to supply air for combu...

Embodiment 2

[0031] The structure of the present invention and its working process are the same as in Embodiment 1. In this example, two rings of air holes are arranged on the circumferential wall surface of the flame cup 2 from bottom to top, the lower ring of air holes 202, the air holes are evenly arranged in the circumferential direction, and the upper ring of air holes 203, the air holes are uniform Arrangement, the number of pores 203 in the upper circle is 1.5 to 2 times that of the pores 202 in the lower circle, and the diameter of each pore is 6 mm.

[0032] The flame beam ring 6 is arranged on the upper edge of the upper circle of air holes 203 or the upper edge of the lower circle of air holes 202 on the circumferential wall of the flame cup 2 .

Embodiment 3

[0034] The structure and working process of the present invention are the same as in Embodiment 1. In this example, fins 401 are arranged on the lower edge of the tumbler, and the number of fins 401 is 30, which are evenly arranged in the circumferential direction. The fins 401 form a certain angle with the bottom plane of the flame cup 2. It is used to turbulence to strengthen the blending of diesel and air, and at the same time enhance the atomization effect of liquid diesel to form a liquid mist fan, which is conducive to ignition and complete combustion.

Abstract

The invention discloses a high-reliability and large power adjusting ratio diesel combustor. The high-reliability and large-power adjusting ratio diesel combustor comprises an outer wall, a flame cup, a flame restraining ring, a shell, a base, a revolving cup, an oil pump, an oil pipe, a motor, a motor supporting frame, a wind wheel, a heat isolation plate, an igniter, a flame detector and an oil releasing pipe. Oil is supplied to the combustor through the oil pump, the motor drives the wind wheel and the revolving cup and the same time, the wind wheel supplies wind to combustion, the revolving cup atomizes diesel, and a combustion cavity is formed by the area between the flame cup and the revolving cup. The wind enters the combustion cavity through a circumferential wall face hole and a center hole of the flame cup. The flame cup is provided with the flame restraining ring for enhancing the rigidity of flames. The igniter and a flame detection sensor are arranged at the bottom of the flame cup. The high-reliability and large-power adjusting ratio diesel combustor is compact in structure, reliable ignition and long-time stable combustion in the open environment at the altitude ranging from 0 m to 5,000 m and the air temperature ranging from -40 DEG C to 40 DEG C or a closed hearth can be achieved; and the flame rigidity is good, combustion is sufficient, the flames can be blue, and the combustion power adjusting ratio can reach 6:1.

Description

technical field [0001] The invention relates to a diesel combustion device, in particular to a cooking and heating burner which can improve the logistics support ability of combat, rescue and field work. Background technique [0002] At present, there are many types of cooking diesel burners used in combat, rescue and field operation logistics support in China, but none of them can meet the needs of high reliability and high power adjustment ratio at the same time, especially in high cold, high altitude, and logistics support capabilities. Cooking and heating needs in poor areas. [0003] Chinese patent 200620058070.3 discloses a diesel burner. Although the patented burner has the characteristics of adjustable firepower and sufficient combustion, it also has defects: the flame is long and poor in rigidity, and is easy to be blown out; There will be serious carbon deposition problems in the interior, which increases the failure rate of parts and shortens the service life; it...
