Industrial furnace insulation
Aerogel insulation materials can be widely used in steam boiler, high temperature melting furnace, high temperature calciner, waste incinerator, muffle furnace, thermal oil furnace, petrochemical plant fractionation tower and so on different kinds, different temperature point furnace. Comprehensive view of these furnaces are mostly thick insulation thickness or surface temperature after heat preservation and heat loss and other issues not meet the use requirements. Most of these furnaces use inorganic insulation materials such as aluminum silicate cotton, rock wool, glass wool and the like, and the thermal conductivities of these materials at 500 ° C. are mostly higher than 0.15 W / m · K.
Problems in this area:
● Traditional materials have poor thermal insulation under high temperature conditions
● Insulation thickness, resulting in large boiler size, and effective use of small space
● insulation is not dense enough, it is difficult to block the hot air
● bulky, high-quality boiler difficult to move
● It is difficult to provide the operator with a safer and more comfortable working environment
Advantages of using Aerogel Insulation materials:
● The thermal insulation effect of aerogels at high temperature is more obvious than traditional materials, which can greatly reduce the heat loss, and the thermal conductivity at 500 ℃ is only 0.035 W / m · K
● effectively reduce the thickness of the insulation, thereby expanding the internal use of space
● Whether airgel or airgel blanket after multiple layers of cracks can play a good effect of blocking the hot air flow
● The Aerogel material can greatly improve the temperature control of the boiler
● better to improve the comfort and safety around the boiler
