Secondary air premixed gas burner for ceramic kiln

Abstract

The invention relates to a secondary air premixed gas burner for a ceramic kiln. The burner comprises a shell, a gas pipeline, a secondary air inlet pipeline and a burning nozzle, wherein the gas pipeline and the secondary air inlet pipeline are coaxially arranged at one end of the shell; the gas pipeline is positioned inside the secondary air inlet pipeline; one end of the gas pipeline extends out of the secondary air inlet pipeline and enters an inner cavity of the shell; a gap is formed between the secondary air inlet pipeline and the gas pipeline to form a secondary air inlet channel; the secondary air inlet channel is communicated with the inner cavity of the shell; and the burning nozzle is arranged at the other end of the shell. An ideal air fuel ratio can be achieved before combustion air is mixed with gas through the secondary air inlet pipeline, and the burner contributes to fully burning the gas, saving energy and reducing emission. During use, the secondary air premixed gas burner for the ceramic kiln can be taken out of the ceramic kiln so as to adjust the air fuel ratio, the burner is arranged in the ceramic kiln after the requirement is met, and the burner is simple and practicable in operation.

Description

technical field [0001] The invention relates to a premixed gas burner for secondary air intake of a ceramic kiln. Background technique [0002] At present, most of the burners used in ceramic kilns are premixed gas burners. For example, Chinese patent 200910027391.5 discloses a rotary premixed gas burner for ceramic kilns, which consists of a shell, an air pipe, a gas pipe and a premixed chamber. The pre-mixing chamber is composed of gas nozzle, nozzle diffuser, combustion-supporting air rotator, honeycomb combustion plate and flame distributor, which is intended to allow gas and air to be mixed twice before entering the combustion chamber, so that the gas can be fully combusted to achieve energy saving and emission reduction the goal of. However, due to its design flaws, the air intake in the premix room is uncontrollable, and the mixture of gas and air cannot achieve the ideal air-fuel ratio, which fails to achieve the designer's original intention of maximizing energy sa...

However, due to its design flaws, the air intake in the premix room is uncontrollable, and the mixture of gas and air cannot achieve the ideal air-fuel ratio, which fails to achieve the designer's original intention of maximizing energy saving.

At the same time, the service life of the honeycomb combustion board is short, and it needs to be replaced frequently, which increases the maintenance cost in the later period; it is not suitable for gas fuel. When gas is used as fuel, the honeycomb combustion board is prone to blockage, and its applicability is small
