Glass fibre tank furnace channel oxygen combustion method

Abstract

The invention discloses an oxygen combustion method for a glass fiber tank furnace passage, which is characterized in that oxygen and fuel gas enter an oxygen combustor through an oxygen pipe and a flue gas pipe respectively, and are combusted in a flame space of the tank furnace passage to heat molten glass on the lower part of the tank furnace passage. The oxygen is prepared by an air separation method, and the concentration of the oxygen is between 50 and 100 percent; and the temperature of the tank furnace passage is between 1,000 and 1,450 DEG C. The oxygen combustion method for the glass fiber tank furnace passage uses the oxygen to replace air and fuel for combustion, improves the flame combustion temperature and the heat utilization efficiency, and reduces generation of waste gas during combustion and energy loss carried away by the waste gas, thereby reducing the production energy consumption and the production cost and achieving the aims of energy conservation, emission reduction and environmental protection.

Description

technical field [0001] The invention relates to a method for burning oxygen through a glass fiber pool kiln. Background technique [0002] The glass fiber tank kiln is divided into two parts, the melting part and the passage. The oxygen combustion technology used in the melting part has been applied at home and abroad, and the current heating method of the passage is the way of heating by air and fuel combustion. The flame temperature of air combustion is not high, the heat radiation ability is weak, and a large amount of nitrogen in the air enters the passage, absorbs a large amount of heat and is discharged from the flue, so the heat utilization efficiency is very low. In addition, air combustion technology has poor temperature control accuracy, generally within ±1°C. In this kind of combustion system, air and fuel are mixed in the mixer first, and then sent to the burner through pipelines; this kind of system is prone to flashback and explosion, which has potential safet...
