Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] Such as figure 1 As shown, the centrifugal burner in this embodiment includes a base 1 , a fire cover 2 and a drive shaft 5 .

[0028] Such as figure 1 As shown, the bottom of the base 1 is provided with supporting feet, and the base 1 is supported on the panel 7 through the supporting feet, so that there is a space for air to pass between the bottom of the base and the panel 7 . There is also a nozzle 3 communicated with the gas pipeline on the panel 7 . Such as Figure 5 As shown, the base 1 in this embodiment is a base 1 with an annular groove, that is, the base 1 includes a horizontally arranged annular bottom wall 12, and an inner peripheral wall of the base vertically extending from the inner peripheral edge of the bottom wall 12. 13 and the peripheral wall of the base extending vertically upward from the bottom wall 12. In t...

Abstract

The invention relates to a centrifugal combustor. The centrifugal combustor comprises a base and a fire cover arranged on the base in a relative rotation manner. The fire cover is provided with a plurality of fire holes. An injection pipe is arranged on the base in the manner of extending in the direction of a nozzle in the rotation tangential direction of the fire cover. At least one blade extending in the radial direction is distributed on the lower surface of the fire cover in the circumferential direction. According to the centrifugal combustor, on the basis that the fire cover rotates relative to the base so as to improve the heat exchange capacity and the heat efficiency, the blades are further arranged on the lower surface of the fire cover, and therefore the flow speed of mixed gasis increased through centrifugal force generated by the rotation of the blades, the energy of the mixed gas is increased, and the heat efficiency is further improved. Meanwhile, the disturbance of the mixed gas is increased through the centrifugal effect of the blades, and the mixing uniformity of the gas is further improved. In addition, negative pressure can be generated through the centrifugalforce generated by the rotation of the blades, external air can be more rapidly supplemented under the effects of nozzle injection and the atmospheric pressure, the injection kinetic energy of the air is increased, and the injection performance is improved.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to a centrifugal burner. Background technique [0002] There are few researches on improving the thermal efficiency of the existing stoves, preventing blockage of the fire cover, and improving the ejection. For example, to improve the thermal efficiency, the main method is to increase the energy gathering circle, which increases the cost and is basically only equipped on high-end stoves. ; In terms of fire cover anti-blocking, various businesses mainly introduce anti-blocking fire covers, basically improving the inner ring fire cover, such as increasing the eaves structure, etc., but the effect is limited; in terms of nozzle ejection, the main direction is to optimize the ejector tube structure and For multi-nozzle ejection, there are few other researches on improving the ejection performance. [0003] The application publication number is CN106642104A (application number is 201610...
