Burner for gas calorific value instrument

Abstract

The invention belongs to the technical field of a gas calorific value instrument, and particularly relates to a burner for the gas calorific value instrument, which comprises a gas inlet, a gas pipe, a high-pressure ignition electrode, the burner, an air pipe body and an air inlet, wherein the gas inlet is connected with a burner base provided with a gas channel; the gas pipe, the high-pressure ignition electrode and the bottom end of the air pipe body are connected with the burner base; the high-pressure ignition electrode and the gas pipe are arranged in the air pipe boy; the gas inlet is communicated with the gas pipe by the gas channel; a nozzle head is communicated with the gas pipe; a circular air mixing board is provided with a thread through hole, symmetrical through holes, a group of circular combustion-supporting air through holes and a group of long-strip combustion-supporting air through holes; and the burner consists of the circular air mixing board, the nozzle head and an injection pipe. The burner for the gas calorific value instrument is simple in structure, capable of guaranteeing the combustible gas to be rapidly mixed and gas with low calorific value to be easily ignited, and safe and stable in the combustion process.

Description

technical field [0001] The invention belongs to the technical field of gas calorific value meters, in particular to a burner for gas calorific value meters. Background technique [0002] The burner used on the traditional gas calorific value meter is mainly composed of gas pipe, air pipe and burner. The burner is inserted into the burner. The combustion-supporting air delivered by the air pipe is mixed at the burner, and once ignited, the flame is directly injected into the burner. However, when a stream of gas is mixed with a stream of combustion-supporting air, it cannot be well mixed evenly because the stream is relatively thick, so it is easy to fail to ignite, and the lower part of the burner has poor combustion effect due to uneven mixing, and the combustion is not complete. The upper part of the burner burns, which is easy to cause misfire. For gas with low calorific value, it is easy to fail to ignite or blow out the flame, and because the gas is not completely bur...

Problems solved by technology

However, when a stream of gas is mixed with a stream of combustion-supporting air, it cannot be well mixed evenly because the stream is relatively thick, so it is easy to fail to ignite, and the lower part of the burner has poor combustion effect due to uneven mixing, and the combustion is not complete. The upper part of the burner burns, which is easy to cause misfire

For gas with low calorific value, it is easy to fail to ignite or blow out the flame, and because the gas is not completely burned, it will take away more heat, making the ambient temperature not meet the combustion conditions
