Boiler 101 | What is a boiler? - Home | American Boiler

In watertube boilers, boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces. Because tubes can typically withstand higher internal pressure than the large chamber shell in a firetube, watertube boilers are used where high steam pressures (3,000 psi, sometimes higher) are required.

Finding the Root Cause of Boiler Tube Failures

Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be …

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

How To Optimize Your Condensing Boiler System For Maximum

Feb 08, 2019 · For condensing boilers, you need a return water temperature of 80°F or lower in order to achieve 97% efficiency. (Look at the efficiency curves from any common condensing boiler manufacturer to see this.) Put another way, you start gaining efficiency only when your return water temperature is approximately 135°F or lower.

Water-tube boiler - Wikipedia

A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved. This is because of condensed tangential pressure on tubes which is known as hoop stress. Water Tube Boiler
