Coal Gas Perlite Expansion Furnace

Coal gas perlite expansion furnace of is a special equipment for expanding perlite. It can be used in refractory industry to produce 0.6g/cm3 light energy-saving refractory bricks and various ultra-light energy-saving refractories.

Compared with the traditional coal gas perlite expansion furnace, in order to meet the market demand, our company has developed a new generation of coal-fired gas expansion furnace with energy-saving, automation, gas-fired, high degree of self-control and environmental protection.
Adopting various dust removal methods to make the whole production line free of dust pollution, more energy-saving and environmental protection.

Major equipment



Expanded perlite has good sound absorption, low moisture absorption and strong frost resistance.

The expanded perlite is widely used as building insulation material, as well as as agricultural soil improvement material to increase soil moisture retention capacity. In addition, it can also be used as auxiliary materials in industrial casting, brewing, filtration, washing and other processes.



1.Low carbon environmental protection.

2.Fully automatic control, saving time and effort.

3.Advanced design and reasonable structure.Less fragile and wearable parts, easy maintenance in later period.

4.The main furnace uses pulverized coal combustion to provide expansion heat. Full and thorough combustion, coal consumption to the minimum, to reduce the overall cost of products to provide convenient conditions.

5.Low energy consumption. Compared with traditional kiln, energy consumption is reduced by 20%-30%, which greatly saves cost.
