Float glass furnace used for multi-fuel combustion

Abstract

The invention relates to a float glass furnace used for multi-fuel combustion. The float glass furnace used for the multi-fuel combustion adopts a multi-spray-gun structure comprising bottom firing nozzle bricks and side firing nozzle bricks. According to the float glass furnace used for multi-fuel combustion, the bottom firing and side firing multi-spray-gun structure is adopted, the interior of the float glass furnace is divided into an internal powder fuel combustion section and a liquid and gas combustion section, and special air-to-fuel ratios are respectively adopted for foot couple of small furnace sections, so that high-quality float glass melt is produced; and a novel matched grid body is adopted, thermophysical characteristic of the grid body and resistance of the grid body to powder fuel corrosion are greatly improved, grid hole is easy to clean due to novel design, and heated surface area is increased. Due to the structure, the float glass furnace used for multi-fuel combustion has the advantages that production efficiency is improved, production cost and maintenance cost are reduced, and the aims of protecting the environment, saving energy and reducing energy consumption are achieved.

Description

technical field [0001] The invention relates to the technical field of float glass, in particular to a float glass kiln for multi-fuel mixed firing. Background technique [0002] The kiln equipment is the core equipment of the production line of float glass and other glass products. After the batch materials for glass production are heated at high temperature, clarified and cooled in the kiln, they become qualified glass liquid that can enter the glass forming equipment. The traditional energy used in float glass kilns is generally liquid or gaseous fuels such as heavy oil, natural gas and producer gas. In recent years, with the increasing shortage of traditional energy sources and rising prices, energy prices account for more and more of the cost of glass production. Bring huge living pressure. In order to adapt to this situation, it has become a trend to use new low-priced fuels such as petroleum coke, pulverized coal and other powdered fuels to burn directly in the kiln,...

AI Technical Summary

Problems solved by technology

Now most of the float glass production lines need large-scale thermal repair of the regenerator lattice body in 1 to 2 years after the fuel is replaced. Therefore, innovative kiln structure, material selection and kiln production control technology are required to match the form of powder fuel. adapt, but there is still no good solution domestically or internationally
