Embodiment Construction

[0039] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0040] The present invention combines the premix burner and the diffusion burner, and takes their respective advantages to solve the problems of easy tempering and unsafety in the complete premix burner and the problems of the diffusion burner. It is difficult to reduce the emission of nitrogen oxides.

[0041] refer to figure 1 , figure 2As shown, a diffusion type full premix burner of the present invention adopts the head of the first embodiment. The burner includes a blower 400 , a transition section 300 , a mixing section 200 and a head 100 connected in sequence. As shown in the figure, the transition section 300 is connected to the air outlet of the fan 400 , the mixing section 200 is connected to the transition section 300 , the machine ...

Abstract

The invention discloses a diffusion type full-premixing burner comprising a fan, a transition section, a mixing section and a machine head which are connected sequentially. Communicated cavities are formed in the transition section, the mixing section and the machine head. A center gun is arranged in the cavities and extends from the transition section to the machine head. The transition section is provided with a first gas inlet. The center gun communicates with the first gas inlet through a first conveying channel. A burning nozzle is arranged at the end, at the machine head, of the center gun. The mixing section is provided with a second gas inlet. A gas ring communicating with the second gas inlet through a second conveying channel is arranged in the mixing section. The center gun is sleeved with the gas ring. Air conveyed in by the fan is mixed with gas conveyed in by the gas ring at the mixing section. The center gun penetrates out of the end of the machine head. The machine headis provided with a plurality of nozzles in the end position. With the structure, the problems that fire return and blocking are liable to occur to a metal fiber surface burning premixing type burner,and nitrogen oxide emissions of a diffusion type burner are large are at least solved.

Description

technical field [0001] The present invention relates to a burner, in particular, the present invention relates to a diffused full premix burner, which can be applied to various types of industrial gas boilers, power generation and chemical production, etc. Background technique [0002] Burners are collectively referred to as devices that allow fuel and air to be sprayed and mixed in a certain way. According to different application environments, they can be divided into industrial burners and civil burners. Taking industrial burners as an example, based on whether premixed or not, it can be divided into completely premixed burners and diffusion burners. [0003] The completely premixed burner is a burner designed according to the completely premixed combustion method. Before combustion, all the air required to complete the combustion is supplied, and the gas and air are fully mixed, and then passed through the burner's jet tube (or metal fiber) Combustion head) is ejected f...
