intercrystalline cracking of water tube boiler

PPD TERMS Flashcards | Quizlet

A boiler that has water on the outside of the tubes with the heat and product of combustion flowing inside the tube. Heat through convection is transmitted through the inside of the tube to the water that is on the outside of the tube. It is the reverse of a water tube boiler

Flush these surfaces completely with water to dissolve, dilute and remove any remaining sulfur compounds. Dry by blowing air through the boiler. All cleaned surfaces should be coated with a good grade of light oil to prevent rust.

2013-5-15 · A water tube boiler is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-

Chapter 5 : Boiler Water - Hawkstone Solutions Inc

Unfortunately, the boiler water directly at the tube surface is much hotter than the bulk boiler water. As vapour bubbles are produced next to the tube wall, the salts capable of being liquefied stay inside the water. This creates a small area with a great amount of salts, even if the bulk boiler water may be lower than the amount of saturation.
