High temperature insulating bricks for glass furnace pool bottom and wall

Jun. 20, 2018

The problem of waste of energy in industrial kilns has always existed, and heat losses generally account for about 22% to 24% of fuel consumption. Kiln insulation has received increasing attention. Conforming to the current environmental protection and energy saving and taking the green policy trend of sustainable development, the energy saving has brought visible benefits to industry. Therefore, the rapid development of high-temperature insulation bricks has made it widely used in industrial furnaces and high-temperature equipment industries.

1. Thermal insulation of bottom of glass furnace pool.

The temperature of the bottom glass in the kiln is increased, and the glass flow increases. The general method for constructing the insulation layer in the bottom of a common glass furnace pool: Usually increase the insulation layer of the bricks in the heavy refractory brick masonry or heavy unshaped refractories construction.

The pool bottom insulation materials are generally: high temperature insulation bricks, fire clay, asbestos and other fire-resistant insulation materials.

2. Wall insulation

For the pool wall, according to the usual practice, the most serious corroded and damaged part is at the inclined surface and the brick seams. Before the insulation measures are taken, ①one should try to grind the masonry plane of the brick wall tiles to narrow the seams between bricks to its minimum. ② Use large-size bricks as much as possible to reduce the number of brick seams. The insulation material of pool wall is generally a high-temperature heat-insulating brick.

The application of high-quality refractories determines the service life of industrial kiln furnaces and high-temperature equipment, the unit energy consumption of products and the output of products. The rapid development of high temperature insulating bricks and the development of various new types of insulation materials have, to some extent, also promoted the development of industrial furnaces.
