There are two main categories of boilers among the different boilers and those two categories are steam boilers and hot water boilers.Either of those categories can be fueled by oil, gas, or electric (although electric is uncommon for steam boilers).
These boilers is largely used in power development and other industrial like sugar industries, cotton industries etc. for steam generation. The main difference between fire tube and water tube is that in fire tube boiler the flue gases flow in the tubes and water flows from the shell and in water tube boiler, water flows from the tubes and the
Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.
When untreated water is used, the heat transfer ability is drastically reduced and leads to overheating, pressure drop, tube failure, and efficiency loss. This is due to dissolved salts and minerals present in water, which eventually gets deposited over the sides of the boiler.
chamber, which again reverses the flue gases and leads them to the end of the boiler in the 3rd smoke tube pass. Hot water boilers are normally completely filled with water during operation. Steam boilers on the other hand are only 3/4 filled with water; the upper quarter is the steam space. 6 | Industrial boiler technology for beginners
