  • How Boilers Keep the Plants and Refineries Running Smoothly

    Water Tube Boilers – In contrast to fire tube boilers; a water tube boiler uses the water rather than the heat which is contained inside of a system of interconnected tubes. The heat moves around the tubes, thereby heating the water within the tubes and gradually transforming it into steam.

For a 2-pass boiler, there is only one bank of tubes, for a 3-pass boiler there are 2 tube passes and for a 4-pass boiler there are 3 tube passes. After leaving the convective section of the boiler, the flue gases exit the pressure vessel at the stack.
