Description
Technical field
The utility model relates to a kind of oxygen and strengthens incendiary glass tank furnace.
Background technology
Along with the rise of energy prices, glass kiln running cost is in continuous lifting in recent years.And because glass kiln quantity-produced characteristic is difficult in and in the kiln operational process it directly is converted to advanced pure oxygen burning mode by the air-breathing mode, this has just expedited the emergence of the birth of oxygen enhancing combustion technology.Oxygen strengthens combustion technology can improve concentration of oxygen in the combustion air by simple means and lower investment, reduces the nitrogen of introducing.Nitrogen can not participate in burning and provide heat for kiln, takes away a large amount of heat on the contrary when discharging kiln.Therefore reduce the nitrogen amount of introducing and can make the kiln energy consumption reduce, exhaust gas emission reduces.Existing oxygen enhancement techniques is installed special macromolecule membrane by the import at burner blower, filters out a spot of nitrogen molecule, thereby improves the oxygen concentration of combustion air.This technique means can be brought up to the oxygen level in the combustion air about 25% by normal 20.9% usually, can realize certain energy-saving effect, but not remarkable.Macromolecule membrane is damaged easily, and cost is higher, and its pressure drop simultaneously is bigger, and the working efficiency of burner blower is also had certain influence.
Summary of the invention
There is the problem that cost height, energy-saving effect are not remarkable, influence fire-retardant blower fan working efficiency in the oxygen enhancing combustion technology that the utility model will solve existing glass tank furnace, provides the oxygen of a kind of save energy and cost, raising efficiency of combustion to strengthen incendiary glass tank furnace.
The technical solution of the utility model:
Oxygen strengthens incendiary glass tank furnace, the air-breathing burner is installed on its breastwork, it is characterized in that: described breastwork is equipped with below the air-breathing burner the oxygen burner of oxygen delivery to glass tank furnace inside, between the front end of described oxygen burner and the internal surface of breastwork spacing is arranged, described oxygen burner is external to oxygen by arm and is responsible for, described arm is provided with the valve of regulating oxygen flow, and described oxygen is responsible for and is connected to the oxygen control station.
Further, described oxygen burner along continuous straight runs is installed on the breastwork.
Perhaps, acclivitous being installed on the breastwork of described oxygen burner.
Further, described oxygen burner is made by stainless steel tube, and its outer end is provided with outside screw.
Further, the oxygen pressure of described oxygen burner is below 100kPa.
Technical conceive of the present utility model about oxygen burner latus rectum 25mm, is level or a fixed angle of altitude with sea line and is installed in about 20cm place, burner below.Leave through hole with drill bit in breastwork upper edge level or certain elevation direction in advance in the position that the oxygen burner is installed, during installation the oxygen burner is inserted this hole, and make the distance of oxygen burner front end apart from about the about 20cm of breastwork internal surface maintenance.Each oxygen burner is connected to oxygen by arm independently and is responsible for, and is equipped with on the arm and regulates the valve that oxygen flow is used.Open the valve of this arm behind the insertion oxygen burner immediately, it is combustion-supporting that oxygen is fed in the kiln, simultaneously can be to oxygen burner cooling protection.The pressure of oxygen is unsuitable too high, should be controlled at below the 100kPa.After inserting whole oxygen burners, regulate the flow of oxygen, according to the pure oxygen total amount that feeds kiln, the combustion air volume that calculating should reduce, and combustion air volume reduced to the calculating desirable value.
In order steadily to provide oxygen to kiln safely, should build an oxygen control station, the oxygen that described control station can provide the outside or the oxygen of locating from gas-holder etc. filters, voltage-regulation voltage-stabilization, safety interlocking, flow metering.Oxygen is sent into each oxygen burner by arm again through being responsible for to the kiln ambient oxygen by pipe-line transportation behind the control station.
The utility model strengthens combustion technology with existing oxygen to be compared, and can arbitrarily improve the amount that is used to strengthen incendiary oxygen, no longer is confined to the filtration capacity of macromolecule membrane to nitrogen molecule.In addition, because oxygen is the below feeding from burner, so the temperature of burner flame bottom can be higher, and radiation capacity is stronger, thereby the heat that glass metal is directly absorbed is more, has improved the thermo-efficiency of kiln.
The beneficial effects of the utility model: invest little, safeguard simple, economic benefit is high, can reduce the energy consumption of glass kiln effectively, reduce exhaust gas emission, and this technology is simple, and is easy to utilize.
