PDF Boilers - University of Alabama

Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure

BOILER CONSTRUCTION : D-type boiler construction | Marine

As the superheated steam passes through the tube bundle, it gives up heat to the boiler water in the water drum. The boiler is protected from the high temperatures of combustion by the refractory. Refractory lines the inside surface of the inner casing enclosing all of the furnace area and extending to the outer row of generating tubes.

Boiler - an overview | ScienceDirect Topics

Boilers are essentially shell-and-tube heat exchangers, with water being boiled to steam or transformed to high-pressure hot water. Heat is generated by burning a fossil fuel; the combustion gas can be ducted around tubes containing the water (water-tube boiler), or the hot gas can pass inside the tubes with the water being in the shell (fire
