The incinerator refractory is an essential piece of marine equipment that is used frequently on vessels. Yet, its maintenance is often overlooked – especially that of the refractory lining in the incinerator.
There are various factors – such as time, temperature and operations – that affect the lifespan of the incinerator refractory. The following four factors have been found to shorten the lifespan of the refractory material:
- Overheating or excessive temperature. This causes the refractory to shrink.
- Spalling, thermal shock due to temperature fluctuations, as well as mechanical shock or compressive forces. These cause the refractory to crack excessively.
- Lack of regular cleaning after each operation of the incinerator. This causes corrosion of the refractory.
- Failure of the steel shell which supports the refractory. This causes mechanical damage to the refractory.
