At present, boilers frequently used in industry include steam boilers and hot water boilers. Steam boilers are generally suitable for power stations, ships and locomotives, and hot water boilers are mainly used for hot water supply.

An auxiliary material commonly used in boilers is thermal insulation. Ceramic fiber is the more commonly used one, such as ceramic fiber needle-punched blankets and ceramic fiber loose cotton. The boiler temperature is not high and cannot reach the temperature level of industrial furnaces. In terms of thermal insulation materials, ceramic fiber materials can be said to be more than enough. For example, the ceramic fiber blanket produced by our company has a temperature resistance of 900-1400℃, and the steam boiler is only about 300-400℃, and the high energy is about 600℃. For some boiler companies, the use rate of ceramic fiber insulation materials is very high.

Another type of boiler is a heat-conducting oil furnace. The temperature of the heat-conducting oil furnace is not high, about 350℃. Generally, the manufacturers of heat-conducting oil furnaces use ceramic fiber loose cotton for insulation, which is the raw material of ceramic fiber needle punched blankets. After the machine needling, the needle-punched blanket is formed, and the loose cotton is directly stuffed into the thermal insulation layer of the heat-conducting oil furnace. Therefore, the requirements for the loose cotton are also very high. In addition to temperature resistance, elasticity also needs to be considered. It cannot be too high, otherwise it will be filled with dissatisfaction.

The main performance characteristics of the ceramic fiber needle-punched blanket are summarized as follows: small bulk density (96/128Kg/m3); low heat capacity (heat storage); low thermal conductivity; excellent thermal shock and mechanical vibration resistance; no oven required; sound insulation performance Good; high heat sensitivity; easy construction and maintenance.
