Ceramic fiber board is a fire-resistant and thermal insulation material that does not generate heat itself, but provides heat protection. Therefore, improving the heat transfer ability of the product can make its application effect better. So how to improve its heat transfer ability?
1. Try to use direct fire heating, immersion combustion, and other heating methods to reduce heat transfer times and improve heating speed.
2. Recycle waste heat, reduce heat loss, reasonably extend the length of the heating furnace, lay ceramic fiber boards in the preheating section, and ensure that the preheating stage can be used to preheat the heated workpiece.
3. Install air preheater and waste heat boiler.
4. Add a series of multi effect heat exchangers.
5. Increase and reasonably arrange heat exchange devices, use high-temperature and low-temperature heating equipment, and improve overall thermal efficiency.
6. If process conditions permit, the heated object should be subjected to thermal loading and the temperature of the thermal loading should be increased as much as possible.
7. Reduce the weight of gantry frames, fixtures, transportation carts, chain claws, roller tracks, etc., and use materials such as ceramic fiber boards with low specific heat and thermal conductivity to reduce their heat storage and ineffective heat during the heating process.
Therefore, generally speaking, in order to improve the heat transfer capacity of equipment, it is necessary to improve the performance and shape of the ceramic fiber board surface on the inner wall of industrial furnaces, enhance its radiation ability, and increase the heat transfer coefficient of heat transfer surfaces such as heat exchangers. However, it is necessary to pay attention to whether the use method is correct. Avoid misoperation and damage to product performance.
