Embodiment Construction

[0019] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] refer to Figure 1-Figure 6 , The gas burner of the present invention uses air as a combustion aid. The combustion-supporting air is sent to the bellows body 6 by connecting the bellows inlet pipe 7 with the outside air inlet pipe or the blower output flange. After passing through the bellows end plate 5, the combustion-supporting air enters the positioning tube 2 and reaches the air Pipe 1 is mixed with gas from fuel pipe 3 .

[0021] Combustion-supporting air and gas can be mixed in the gap cavity between the air flow nozzles, or can be mixed after the gas flow is diffused through the combustion chamber. The gas and combustion air will be further mixed in the space behind the combustion chamber to form a mixed combustible gas, which will fill the entire cross-section of the burner inner tube. The ...

Abstract

The invention discloses a modular gas burner and an operation method thereof. The modular gas burner comprises an airflow nozzle composed of an air pipe, a positioning pipe and a fuel pipe. The modular gas burner also comprises an air bellow cylinder, an air bellow air inlet pipe, a connecting system, positioning round steel and a porous medium body assembly. Combustion-supporting air is connected with an output flange through the air bellow air inlet pipe and an external air introduction pipe, is fed into an air bellow cylinder, passes through an air bellow end plate, enters the positioning pipe and the air pipe, and is further mixed with fuel gas from the fuel pipe for combustion. The air bellow cylinder is connected with a combustion chamber through an air bellow outer flange, and the combustion chamber is formed by connecting a mixing chamber and a pre-combustion chamber through positioning pins and pins. The invention further provides an operation method of the modular gas burner. The problems that in the prior art, a burner cannot be filled with sufficient combustion improver, and normal and continuous combustion of low-heating-value fuel gas cannot be guaranteed are solved.

Description

technical field [0001] The invention relates to a gas burner and its operation method, in particular to a high-efficiency combustion burner which can be used for low-grade gas and its operation method. Background technique [0002] With the development of industry, energy consumption increases sharply, and energy waste is serious at the same time. As an energy-consuming product, the burner has a huge market share, and its energy utilization rate has become an important issue that people pay attention to. The burner mainly burns fuel and air. For a burner that does not use an injection structure, the air and gas are mixed in advance, and the fuel and air are sent into the combustion zone. The structure and arrangement of the burner nozzle determine the air and gas degree of mixing and combustion. And how to carry out sufficient and effective mixing directly affects the utilization rate of fuel energy, the thermal efficiency of the burner and the emission of pollutants. The...
