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.

Technical field
The present invention relates to a kind of glass fibre tank furnace channel oxygen combustion method.
Background technology
Glass fibre tank furnace is divided into melting end and two parts of path, and wherein melting end adopts the oxygen combustion technology all to be applied at home and abroad, and the path type of heating all is the mode that adopts air and fuel combustion heating at present.The flame temperature of air combustion is not high, a little less than the thermal radiation capability, and a large amount of nitrogen inlet passage in the air, discharges from flue after absorbing a large amount of heats, so efficiency of utilization is very low.In addition, the air combustion technology is poor to temperature control precision, generally at ± 1 ℃.In this firing system, air and fuel mix in mixing tank earlier, arrive burner by pipe-line transportation then; This system easily produces back draft, has potential safety hazard.
Along with the aggravation of glass industry competition, fuel price soaring, the growth day by day of production cost, in order to reduce production energy consumption, reduce product cost, and the energy-saving and emission-reduction call of active response country, adopting the oxygen combustion technology on glass fibre tank furnace channel is inexorable trend.
Summary of the invention
Technical problem solved by the invention provides a kind of glass fibre tank furnace channel oxygen combustion method, promptly uses oxygen to replace air and fuel to burn, thereby reaches the target of energy-conservation and environmental protection.
The present invention solves the technical scheme that instantaneous technical problem adopts: this glass fibre tank furnace channel oxygen combustion method, it is characterized in that oxygen and combustion gas respectively oxygen channel and the gas pipeline by separately enter oxygen burner simultaneously, oxygen and combustion gas are heated the glass metal of tank furnace channel bottom in the flame space internal combustion of tank furnace channel.
Oxygen of the present invention makes by air separating method, and concentration of oxygen is 50%～100%.
The temperature of tank furnace channel of the present invention is at 1000 ℃～1450 ℃.
Oxygen of the present invention enters oxygen control valve and carries out oxygen flow control after carrying out the oxygen flow measurement through oxygen flow meter, is delivered to oxygen supply manifold then, enters oxygen burner through oxygen hose, oxygen valve and oxygen metallic hose again.
Combustion gas of the present invention enters gas control valve and carries out gas flow control after carrying out the gas flow measurement through gas meter, is delivered to gas distribution pipe then, enters oxygen burner by gas line, gas valve and combustion gas metallic hose again.
The present invention uses oxygen to replace air and fuel to burn, flame temperature and efficiency of utilization have been improved, reduce in the combustion processes generation of waste gas and the power loss that waste gas is taken away, thereby reduced production energy consumption and cost, reached the target of energy-saving and emission-reduction and environmental protection.
