What Is A Water Tube Boiler And How Does One Work?
A water tube boiler is a variety of boiler which circulates water in tubes. The water in these tubes is heated by a fire, located outside them. Commonly used in high pressure boilers, water tube boilers burn fuel inside a separate furnace. This creates heated gas, which transfers the heat to the water inside the tubes. This water becomes steam, which can be used for heating, to drive turbines, and for all kinds of other day to day uses. Smaller boilers use multiple tubes separate from the furnace, while larger utility water tube boiler installations actually build the tubes directly into the walls of the furnace itself. When the water is heated, it rises into a part of the boiler called the steam drum. Saturated steam is removed from the top of the drum. It may then re-enter the furnace via a superheater, creating what’s called superheated steam. This is the kind of steam used to drive turbines, such as those used to make electricity. This is because ordinary steam is full of water dro
