2008-5-8 · If I may elaborate further, the calculation based upon the outside diameter and will give a required thickness on the assumtion that OD - 2tr will give ID. If the calculation is performed based on ID the the result will give a required thickness of ID+2tr to equal OD. This tr will only be equal if the shell thickness considered is EXACTLY the tr.

2004-3-19 · 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
