Combustor for horseshoe flame glass kiln, glass kiln and burning method

Abstract

The invention discloses a combustor for a horseshoe flame glass kiln, the glass kiln and a combustion method. The combustor comprises a combustor body, wherein the combustor body comprises a gas outercavity and a gas inner cavity sleeved with the gas outer cavity, the tail of the gas outer cavity and the tail of the gas inner cavity are both sealed, the head of the gas outer cavity and the head of the gas inner cavity are both open, a gas main inlet is formed in the tail of the gas outer cavity, and an inner cavity gas inlet communicated with the gas outer cavity is formed in the gas inner cavity; the combustor further comprises an adjusting assembly used for adjusting the section opening rate of the gas outer cavity. According to the combustor for the horseshoe flame glass kiln, a stageddouble-flame combustion mode combining long flame and short flame is achieved, the reaction speed of fuel gas and combustion-supporting air is decreased, the severe combustion degree of the fuel gasis decreased, and the local high temperature of a flame space is avoided. Meanwhile, excess air is reduced, the excess air coefficient is reduced, and the purpose of reducing generation of nitric oxide is achieved.

Description

technical field [0001] The invention relates to the technical field of glass kiln combustion, in particular to a burner for a horseshoe-flame glass furnace capable of reducing nitrogen oxide emissions, a horseshoe-flame glass furnace equipped with the burner, and burning with the burner Methods. Background technique [0002] my country's daily-use glass industry has entered a period of rapid development, and has now developed into a major producer of daily-use glass products in the world. Due to the basic characteristics of daily-use glass production, such as high consumption of natural mineral resources, high energy consumption, and pollution in the production process, in the face of increasingly intensified resource and environmental constraints, it is necessary to ensure continuous improvement in the output and quality of glass products. Environmental protection and energy saving. [0003] In order to increase the melting speed of the glass liquid in the existing horses...
