Poor operating practices can also result in thermal shock. Since an operating boiler uses the medium of heat transfer, it is constantly under stress. Often when water is added to the system, it has a cooler temperature than the existing water. If this addition is done improperly, you could shock the system, thermally. The best way to prevent thermal shock damage to a boiler is to prevent rapid changes in water temperature within the boiler.
Thermal shock is more often preventable.
We must know how the steam that the client's equipment will provide works as a part of the overall process. This data will greatly affect the determination of a system design that will competently serve the client's demands at the lowest cost.
