  • Thermally Induced Stress Cycling (Thermal Shock) in

    Boiler pressure - higher pressures mean higher temperatures. The only factor affecting shell-metal temperature is the bulk water temperature of the boiler. This is a function of the return water temperature and flowrate, and also burner firing rate. Obviously, low bulk water temperatures mean low shell-metal temperatures and vice versa.Learn More
