All You Need To Know About Boiler Tube Cleaning | Techcolite

Basically, there are two types of boilers. These are the fire-tube and water tube boilers. In water tube units, water is circulated within the tube and heated by hot gases from the furnace until it becomes high-pressure steam. On the other hand, fire-tube boilers have water surrounding them. Hot gas is passed through and this heats up the water.
