WebNew calculations show, for instance, that if liberated in a rupture, a 30-gallon hot-water tank at 90 psig (or 104.7 psia) has approximately 314,095 foot-pounds of energy to flash its water into steam at 332°F. Translate that force potential into real-world terms and you have the example of the car being rocketed into the air as noted above. WebAug 13, 2015 · If the system return water temperature is 150 degrees F, the supply water temperature to the system from the boiler should be 20-25 degrees F higher. A temperature span greater than the boiler design temperature rise could cause Thermal Shock inside the boiler. Thermal shock can literally shake a boiler apart due to rapid expansion and …
Webcold boiler in high-fire or the condensate returning to the bottom rear of the boiler too cold. However, the incidences of thermal shock in steam boilers are not many. In hot water boilers, the greatest cause, by far, is the three-way, system temperature control valve. In the spring and fall, our system may have water as low as 100 degrees in ... WebI think that one reason to use hot water is that it should already have some of the oxygen removed due to the fact that the solubility of gas in water decreases as temperature rises. Less oxygen --> less corrosion. I cannot think of any benefit from using cold water or harm in using hot water. Thanks, Welcome It looks like you're new here.
