Premixed adjustable gas burner and method

Abstract

The invention discloses a premixed adjustable gas burner and a method. The premixed adjustable gas burner comprises a gas pipe (5), wherein the gas pipe (5) is fixedly connected with a mixing pipe (4), the mixing pipe (4) sleeves the gas pipe (5), a secondary air inlet (3) is formed in the mixing pipe (4), a certain gap is reserved between the mixing pipe (4) and an air pipe (1), the air pipe (1) sleeves the mixing pipe (4), and a main air inlet (2) is formed in the air pipe (1).

Description

Technical field: [0001] The invention specifically relates to a premixed adjustable gas burner and a method thereof, which belong to the technical field of kiln combustion and are suitable for the combustion application of refractory materials. Background technique: [0002] As far as the inventor knows, the current domestic combustion devices used in the sintering process of refractory materials are installed in fixed positions, and various valves are often adjusted when adjusting the burner. It is not good to cause a waste of natural gas. Invention content: [0003] The purpose of the present invention is to overcome the above-mentioned defects, and provide a premixed adjustable gas burner and method that can stabilize the atmosphere in the kiln, fully mix the air and natural gas, make the air and natural gas rationally utilized, and have high combustion efficiency. . [0004] The present invention is realized according to the following technical scheme. The premixed a...
