A steel-structured fixing frame is arranged on the periphery of the cavity and the furnace cover. A feeding port is arranged on a long side of the cavity. A flue is arranged on a short side of the cavity, and a glass discharge port is arranged on the other short side of the cavity. A bottom wall is arranged on the bottom of the cavity. Tank walls are arranged on two sides of the bottom wall, such that a glass tank furnace is formed. Parapets are arranged above the tank walls on the two sides. More than one burning lances are arranged at a certain height above the parapets. The burning lances comprise natural gas inlets and pure oxygen inlets.
Description
Technical field
The present invention relates to a kind of device firing devitrified glass, particularly a kind of full-oxygen combustion kiln manufactured for low-expansion glass-ceramic.
Background technology
Low-expansion glass-ceramic is owing to having high-melting-point, high mold temperature, and during with common air-breathing furnace, the defect of glass is more.As bubble, calculus, lines etc.; Its mold temperature cannot be ensured simultaneously, cause glass ware forming operational difficulty.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of full-oxygen combustion kiln manufactured for low-expansion glass-ceramic.
In order to solve the problems of the technologies described above, the invention discloses a kind of full-oxygen combustion kiln manufactured for low-expansion glass-ceramic, comprise the cavity of rectangular structure and be positioned at the bell at cavity top, the periphery of cavity and bell arranges steel construction fixed frame, the side, long limit of cavity is provided with charging opening, two minor faces of cavity, while be provided with flue, the other side is provided with glass discharge door, cavity bottom is diapire, diapire both sides are set to pool wall thus form cell furnace, above the pool wall of both sides, respectively breastwork is set, certain altitude place, breastwork top is provided with the burning rifle of more than, described burning rifle comprises Sweet natural gas inlet mouth and pure oxygen inlet mouth.
In the present invention, below described diapire, be provided with thermal insulation layer.
In the present invention, coated thermal insulation layer outside described pool wall.
In the present invention, coated thermal insulation layer outside described breastwork.
In the present invention, described rectangular structure has certain aspect ratio range between 1:1 ~ 4:1; Breastwork height is between 500 ~ 1500mm.
In the present invention, described burning rifle is that rifle is burnt in flat exterior mixing classification.
In the present invention, the burning on the breastwork of described both sides is robbed in being staggered or parallel arranged opposite.
In the present invention, described burning rifle is positioned at the position of more than metal level 200 ~ 500mm.
In the present invention, the described pool wall degree of depth is 500 ~ 1000mm.
Beneficial effect: 1, owing to using oxygen and fuel compatibility, improve combustion conditions, makes burning more abundant, can fuel saving, raising Enterprise Integrated benefit;
2, higher flame space temperature more combustion-supporting than normal air can be produced during pure oxygen burning, the burn-off rate of glass can be accelerated, so pure oxygen burning glass furnace can obtain higher melting rate, effectively improve unit surface load (about more than 25%);
3, owing to using oxygen and fuel compatibility, improve combustion conditions, more fully thoroughly, can significantly reduce nitrogen oxides emission amount, the range of decrease can reach more than 80% in the burning of fuel;
4, do not need during pure oxygen burning furnace operation to carry out switch operation as traditional glass kiln, effectively can reduce the discharge of dust, the flying upward of admixtion, admixtion waste can be saved, can alleviate simultaneously and fly upward the erosion of dust to positions such as arch top and breastworks;
5, power consumption (electricity fusing-aid, gas blower) is saved; To reduce investment outlay cost (floor space, steel construction, EP, regenerator, deNOx system, combustion air blower etc.);
6, pure oxygen burning kiln can provide larger margin of energy, can improve kiln furnace temperature rapidly in the short period of time as required, make kiln load variation range more flexible;
7, burn without the need to commutation, kiln is because of flameholding, and technique is more stable, is conducive to improving yield rate, improves product quality;
8, reduce non-fusant, reduce micro-bubble amount, reduce and be mingled with (striped).
