Description

Technical Field

[0001] The utility model relates to the technical field of premixed burners, in particular to an energy-saving and environment-friendly premixed burner. Background Technique

[0002] In a premixed burner, premixed combustion occurs before combustion, where fuel and oxygen are fully mixed inside the burner. It is another typical combustion method compared to diffusion combustion. Premixed combustion generally occurs in a closed system or an open system where the diffusion rate of the mixed gas into the surroundings is much slower than the combustion rate. The heat released by combustion causes the volume of the product to expand rapidly and the pressure to increase.

[0003] The utility model relates to the technical field of premixed burners, in particular to a premixed burner (CN218599710U). The premixed burner includes: an annular support frame, on the upper surface of which there is an annular guide rail, and on the upper side of one end of the annular support frame there is a slider; a positioning block located at one end of the slider, with a moving groove provided at the bottom of the positioning block, a push plate provided inside the moving groove, a gasket provided at the upper end of the push plate, and a damping strip provided at the upper end of the gasket; a rotating rod located inside the push plate, with a rotating block provided at the bottom of the rotating rod and a pinching groove provided on the outside of the rotating block. The beneficial effect is that by setting the rotating rod in cooperation with the push plate, the positioning block can be positioned, so that the slider is fixed on the annular support frame, avoiding the slider from moving during combustion and affecting the heating situation of the premixed burner. However, during use, some flue gases cannot follow the combustion head for full combustion, polluting the air. At the same time, the impurities in the flue gases will also adhere to the combustion chamber, resulting in the subsequent fuel of the burner accumulating on the impurities and igniting the combustion chamber, reducing the fuel utilization rate and bringing troubles to users.

[0004] Therefore, we propose an energy-saving and environment-friendly premixed burner. Content of the Utility Model

[0005] The purpose of the utility model is to provide an energy-saving and environment-friendly premixed burner to solve the problems raised in the above background technique.

A combustion chamber is bolted to the end of the end plate away from the machine body, and a high-temperature resistant ceramic plate is laid on the inner wall of the combustion chamber. The front end of the combustion chamber is bent into a base with a supporting function, and a scraping plate is laid on the upper end of the base. Unburned impurities are attached to the surface of the scraping plate.

[0007] Preferably, the tail end of the combustion nozzle is connected to a connecting pipe, and one end of the connecting pipe away from the combustion nozzle is connected to a fuel delivery pipe.

[0012] Preferably, a smoke nozzle is connected to the gas outlet of the delivery head.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the energy-saving and environmental protection premixed burner is in use, the entire combustion nozzle serves as a combustion component. The fuel is transported to the connecting pipe in a pressurized manner through the fuel delivery pipe, and the fuel is transported to the combustion nozzle to meet the combustion requirements of the burner. At the same time, a blower for adding oxygen is distributed at the rear end of the combustion nozzle, and the air at the combustion nozzle is supplemented through the blower to meet the requirement of sufficient fuel combustion.

[0014] The entire smoke dispersion pipe transports the flue gas flowing into from the inlet smoke pipe to each branch pipe of the smoke dispersion pipe through the blower system.
