Description

(54) БАННАЯ СТЕКЛОВАРЕННАЯ ПЕЧЬ(54) BATHROOM GLASS FURNACE

1one

Изобретение относитс к ванным стекловаренным печам.The invention relates to bath furnaces.

Известны ванные стекловаренные печи, включающие варочный бассейн с зоной осветлени , образованный сводом, стенами и подом 1,2.Bathrooms of glass melting furnaces are known, including a brewhouse with a clarification zone formed by the vault, walls and hearth 1.2.

Сопр жение пода (дна) и стен бассейна в них выполн етс под пр мым углом.The mating of the hearth (bottom) and the walls of the pool in them is performed at a right angle.

Ввиду значительного уменьшени термического сопротивлени в угловом сопр жении удельные тепловые потери в углах бассейна оказываетс намного бсэтьшими, чем в отдалении от них. Это приводит к резкому снижению температуры в углах бассейна и способствует формированию таких пристенных конвекционных потоков, которые увлекают шихту, загруженную в бассейн на поверхность стекломассы, к боковым стенам. Вс поверхность расплава в зоне варки оказываетс покрытой слоем шихты, преп тствуюш.им проникновению тепла от пламенных газов к стекломассе, температура последней резко снижаетс , и варка стекла замедл етс . Кроме того, непо2Due to the significant decrease in thermal resistance in the angular conjugation, the specific heat loss in the corners of the basin is much better than at a distance from them. This leads to a sharp decrease in temperature in the corners of the pool and contributes to the formation of such near-wall convection currents, which carry the charge loaded into the pool on the surface of the glass mass to the side walls. The entire surface of the melt in the cooking zone becomes covered with a layer of the charge, preventing the heat from the fiery gases from entering the glass melt, the temperature of the latter sharply decreases, and the cooking of the glass slows down. In addition,

средственный контакт шихты с огне,aj рами бассейна ускор ет их коррозно,the medium contact of the charge with the fire, aj the pool rams accelerates them corrosively,

Цель изобретени - повышение качеств стекломассы и к.п.д. печи,The purpose of the invention is to improve the quality of glass and efficiency. furnaces

Это достигаетс тем, что в предлагаемой печи под бассейна, по крайней . на половину его длины с двойным уклоном под углок--. 5-45° к продо.пьной оси.This is achieved by the fact that in the proposed pool furnace at least. half its length with a double bias at an angle--. 5-45 ° to the supply axis.

На фиг, 1 показана печь, продольный разрез; на фиг, 2 - разрез по на фиг, 1; на фиг, 3 - схема движени стекломассы в печи; на фиг 4 - распределени температуры стегшомассы в поперечном сечении печи.Fig, 1 shows a furnace, a longitudinal section; FIG. 2 is a sectional view of FIG. 1; Fig. 3 is a flow chart of the glass melt in the furnace; Fig. 4 shows the temperature distribution of the mass in the cross section of the furnace.

Стекловаренна печь включает варочг-гы бассейн, состо щий из зоны варкк. под 1 которой выполнен с двойным уклонов:,, и зоны осветлени с плоским дном 2, прото 3 и выработочный проток 4, Печь отапливаетс с помощью горелок 5,A glass melting furnace includes a cooking pool consisting of a warkk zone. under 1 which is made with double slopes: ,, and a zone of clarification with a flat bottom 2, proto 3 and the production duct 4, the furnace is heated with the help of burners 5,

Claims

The slopes of the bottom of the cooking basin are made at an angle cL 15 ° to the longitudinal axis of the furnace. The vertical part of the cooking wall 6 of the cooking basin is no more than 2/3 of the maximum lip of the basin and is equal to the depth of the wasp; uteni. The mixture is fed to the furnace with cr 7 ore; end loading pocket, the width of which is no more than 0.8 of the pool width, As a result of cooling of the glass mass 8 under the charge layer and intensive heating of the glass mass through the free surface in sections 9 and 10 of the open mirror, convection currents J.1 appear between the layer of the charge and the side wall of the bath and 12, which direct the floating charge to the furnace axis, the Construct-l of the cooking basin with double slopes of the year allows to improve the quality of glass melt, productivity and efficiency. furnaces due to more intense heating of the glass melt near the side walls of the pool, increasing the glass mass temperature both at the side walls and under the charge layer, and also due to the elimination of stagnant layers in the corners due to an increase in the temperature in them. Moreover, such a Vm design of the cooking basin ensures a reduction in the volume of glass mass in it and a decrease in the heat transfer surface of the furnace elements enclosing the glass mass, which also contributes to an increase in the quality of glass mass and efficiency. ovens. Claims of the invention A glass-melting stove bath comprising a brewhouse with a lightning zone formed by the vault, walls and hearth, which is designed to improve the quality of the glass melt and CoP.d, half the length of the stove. with a double bias at an angle of 5-45 ° to the longitudinal axis.
