The solution in most cases is to modify the boiler and/or feedwater system to prevent the sudden entry of cold water into hot boiler components. When a boiler is experiencing cracking due to subcooling and cold feedwater flow upon startup, one solution is to install an offline pump-assisted circulation system to reduce the thermal transients.
