Full-premixing gas gun with flame stabilizing function

Abstract

The invention relates to a full-premixing gas gun with a flame stabilizing function, and belongs to the field of burners. The full-premixing gas gun comprises a premixing pipe and an ignition electrode, wherein the ignition electrode is located in the premixing pipe, a ventilation seat cylinder is arranged at one end of the premixing pipe, the ventilation seat cylinder communicates with the premixing pipe, an air connector and a gas connector are arranged on the ventilation seat cylinder, the air connector and the gas connector communicate with the ventilation seat cylinder, and the air connector is located on the side, far away from the premixing pipe, of the gas connector; and a flow control mechanism is arranged in the ventilation seat cylinder, the flow control mechanism comprises a throttling disc, the throttling disc is located between the air connector and the gas connector, the throttling disc divides an inner cavity of the ventilation seat cylinder into an air cavity and a gas cavity, a pressure change hole is formed in the throttling disc, the air cavity communicates with the air connector, and the gas cavity communicates with the gas cavity. According to the full-premixing gas gun, the stability of two airflow directions in the ventilation seat cylinder is improved through the flow control mechanism, and the effect of reducing the probability that gas flows to the air cavity and leaks is achieved.

Description

technical field [0001] The present application relates to the field of burners, in particular to a fully premixed gas gun with a flame stabilizing function. Background technique [0002] The burner is a general term for devices that make fuel and air spray out and combust in a certain way. Burners can be divided into industrial burners, burners, civil burners, and special burners. According to its working principle, a burner can be defined as a kind of equipment that converts substances into heat energy through the chemical reaction of burning, that is, air and fuel are mixed in an appropriate proportion through a premixing device to make them fully burnt. [0003] The gas gun is the core component of the burner, which includes an ignition electrode and a pipeline for gas supply, gas support or air circulation. The gas gun is usually in the shape of a slender rod, and one end is the operating end. The operating end enters, and the switch of the ignition electrode is also l...

Problems solved by technology

[0005] For the above-mentioned related technologies, the inventor believes that there are the following defects: air and gas are mixed after entering the gas gun, that is, the pipelines for air and gas entering the gas gun will be directly or indirectly connected, if the airflow channel inside the gas gun If the internal pressure is unstable, gas will flow into the air input connection pipe by mistake, causing gas leakage and increasing safety hazards
