Application analysis of aerogel insulation blanket in thermal insulation of furnace body
Aerogel insulation materials can be widely used in steam boiler, high temperature melting furnace, high temperature calciner, garbage incinerator, muffle furnace, heat conduction oil furnace, fractionating tower of petrochemical plant, and various kinds of different temperature points. Generally speaking, most of these furnaces have problems such as too thick insulation layer or surface temperature and heat loss after insulation. Most of these furnace bodies use inorganic thermal insulation materials such as aluminum silicate, rock wool, glass cotton and other inorganic materials. The thermal conductivity of these materials at 500 degrees centigrade is much higher than that of 0.15W/m. K.
Problems faced in this area:
The thermal insulation performance of traditional materials is poor under high temperature conditions
The thickness of the insulation layer is large, resulting in large volume of boiler and effective use of space.
Insulation is not good enough to block hot air flow.
Large, mass boilers are difficult to move
It is difficult for operators to provide a safer and more comfortable working environment.
The advantages of aerogel materials are:
The heat insulation effect of aerogel material at high temperature will be more obvious than that of traditional material, and the heat loss can be greatly reduced. The thermal conductivity at 500 C is only 0.035 W/m K.
Effectively reduce the thickness of the insulation layer, thereby expanding the internal use space.
No matter whether the pneumatic rubber plate or the aerogel blanket is used for multi-layer cross stitching, it can play a good role in blocking the hot airflow.
The use of aerogel material can greatly improve the temperature control of boilers.
Better improve the comfort and safety of the boiler's surrounding environment.
