Thermal shock in Glass
When heating or cooling applied in Glasslined Reactor - temperature difference between reactor inner fluid and heating or cooling should not high.
High difference between inner fluid temperature and heating or cooling source will be damaged due to thermal shock.
Graph 1: Reactor inner fluid temperature vs Heating source temperature.
Graph 2: Reactor inner fluid temperature vs Cooling source temperature.
We can How much temperature difference maximum allowable.
Examples of Glass lining failure
Glass lining side
1. If Glass lined wall temperature is 10°C
Then fluid inner temperature should be 160°C
2. When Reactor inner temperature is 180°C then Cooling source temperature must above 50°C.
3. When Reactor inner temperature is 0°C then heating source temperature must below 140°C.
4. When Reactor inner temperature is 20°C then heating source temperature must below 170°C.
