Abstract

The invention relates to an industrial gas burner. The industrial gas burner comprises a cylindrical housing, and a gas guide pipe arranged in the housing, wherein a burning head is arranged in the front end of the housing and adjustably sleeved on the gas guide pipe; a swirler is arranged at the front end of the housing, and an air guide blade inclined to an axis of the housing is fixed onto the swirler; a front cover is also arranged at the front end of the housing, with the front end contracted inwards to form a circular opening, and the inside diameter of the opening is more than the outside diameter of the burning head. According to the industrial gas burner, the swirler is arranged outside the burning head, which can further promote the gas burning during burning under gas, and moreover, the flame in burning can be spread to the outside by means of rotating through the swirler, therefore, the burning area of the flame is expanded. The front cover is arranged at the front end of the burning head, and the edges of the flame in burning are baffled by the front cover, thus, the edges are forcibly close to centre of the flame, and spewed out from the opening at the front cover, and the flame in burning is collected and extended, and the full burning is achieved, the emission of CO and NOx is reduced, and the stability of the flame is improved.

Description

[0001] technical field

[0002] The invention belongs to the technical field of gas combustion, in particular to an industrial gas burner.

[0003] Background technique

[0004] No matter what kind of gas is burned, air is needed to support the combustion. The mixing ratio and mixing degree of gas and air determine the degree of combustion of gas. The more fully the gas is burned, the higher the calorific value it produces, and the least waste gas and harmful gas are produced after combustion, so as to achieve the goals of high efficiency, energy saving and environmental protection.

[0005] From the perspective of aerodynamics, the stoves on the market can be divided into two categories of products, one is natural wind stoves, and the other is blast stoves. The combustion modes of blast stoves on the market are all post-mixed combustion modes, that is, the gas is mixed with the air synchronously during the combustion process in the furnace cavity. Because the gas is diffi...
