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

Abstract

The invention discloses a burner for a horseshoe flame glass kiln, a glass kiln and a combustion method. The tails of the gas cavity and the gas inner cavity are sealed, and the heads are open. The tail of the gas outer cavity is provided with a gas main inlet, and the gas inner cavity is provided with an inner cavity gas inlet that communicates with the gas outer cavity; The adjustment component of the cross-sectional opening ratio of the gas outer cavity. The horseshoe flame glass kiln burner of the present invention realizes a staged double-flame combustion mode combining long and short flames, delays the reaction speed of gas and combustion-supporting air, slows down the degree of violent combustion of gas, and avoids local high temperature in the flame space. At the same time, the excess air is reduced, the air excess coefficient is reduced, and the purpose of reducing the generation of nitrogen oxides 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...
