Problems solved by technology

[0036] The second object of the present invention is to provide a melting furnace for producing glass, especially flat glass, using a completely premixed combustion melting method, which solves the problems of low heat energy utilization rate, high raw material cost, and low quality of finished products existing in existing glass melting furnaces. It can greatly improve the utilization rate of heat energy, and replace the precious soda ash in the raw material with cheap sodium sulfate, so that there will be no problems caused by excessive use of sodium sulfate, and the harmful exhaust gas sulfur dioxide and fuel combustion generated after using sodium sulfate The sulfur dioxide produced can be recovered efficiently and high-quality sulfuric acid can be produced. Using coal powder with wide sources and low price as fuel can further reduce production costs. Under the conditions of the same furnace area, energy consumption and time, it can produce 2 to 3 times more high-quality flat glass liquid than current furnaces

Embodiment Construction

[0088] figure 1 It is a flowchart of the smelting combustion method of the present invention, figure 2 It is a schematic diagram of the furnace structure using the smelting and combustion method of the present invention. After the coal is crushed by the rod mill to meet the required particle size, it enters the pulverized coal bin, but the moisture content of the pulverized coal must be controlled to ensure unimpeded passage through the pressurized coal lock hopper device. The pulverized coal entering the furnace is transported from the pulverized coal bin to the pressurized coal lock hopper, and the pressure of the lock hopper fluctuates periodically between the atmospheric pressure and the working operating pressure. After the pulverized coal enters the pressurized coal lock hopper, it enters the fuel supplier 33 below through a valve. Under the action of gravity, the pulverized coal is sent to the fuel delivery pipe 30 communicating with the fuel supplier 33. The dense p...

Abstract

The invention relates to a full premixed combustion smelting method and smelting furnace for producing glass using the method, wherein the method consists of disintegrating the raw materials, mixing and loading into flame for full contact with the flame, thus realizing completely premixed combustion and smelting, the droplets formed in smelting fall into the smelting pool through colliding each other and forming shaped liquid. The disclosed method can increase utilization factor of heat energy substantially.

Description

technical field [0001] The present invention relates to a combustion melting method of a melting furnace and a melting furnace using the method to produce glass. Background technique [0002] Due to the highly mature production technology of glass, especially flat glass, specialized production enterprises have manufactured various types of flat glass production equipment according to certain standards and specifications, and the price of equipment has been reduced to a normal level. Therefore, the technical level of the flat glass industry is basically Quite, the level of profitability is also quite, making flat glass from a commodity in short supply in the past to an ordinary consumer product rapidly, and in just a few years, the supply exceeds the current demand, and the entire flat glass industry is in a state of meager profit and loss. status. Due to the highly mature technology, resource-based medium-sized enterprises are winning one after another in the market, while ...
