Problems solved by technology

Due to the hot air floating upwards, although the temperature of the burning furnace top is very high, the temperature of the glass liquid surface is indeed low. The liquid temperature is low, the output of glass products is limited, and the quality of glass products is difficult to be guaranteed. At the same time, due to the low heating efficiency of the glass liquid, the energy consumption is very large.

By the adoption of the method provided by the invention, the combustion-supporting investment for glass kiln is small, the energy saving effect is obvious, the output and quality of a glass product can be greatly raised, the service life of the kiln can be prolonged, and the flue gas emission can reach the standard.

Description

technical field [0001] The invention belongs to the field of glass kilns, and relates to a local oxygen-increasing, combustion-supporting and energy-saving method that is widely applicable to glass kilns such as horseshoe-type regenerative pool kilns, horizontal flame kilns and crucible kilns. technical background [0002] Whether it is a horseshoe-shaped regenerative floor kiln, a horizontal flame kiln or a crucible kiln, for the convenience of use, the flame is set above the glass liquid surface. Due to the hot air floating upwards, although the temperature of the burning furnace top is very high, the temperature of the glass liquid surface is indeed low. The liquid temperature is low, the output of glass products is limited, and the quality of glass products is also difficult to be guaranteed. At the same time, due to the low heating efficiency of the glass liquid, the energy consumption is very large. Contents of the invention [0003] The object of the present invent...
