Model Boiler Material?? - practicalmachinist.com

Jan 28, 2010 · For smaller barrels, in the 8 inch or under diameter typically they are copper, you can make them a bit thinner and the heat transfer is way better. For a boiler your size definitely copper. Depending on how much steam you want determines the boiler. Water or fire tube boiler. But there are hundreds of designs out there for stationary boilers.

Simple Boiler Design - Steve's workshop

The pressure vessel was designed around a piece of 50mm diameter copper tube of 1.2mm thickness. Although over-thick for a boiler operating at these pressures, it was a standard available size and removed the need to roll a shell from sheet material. The end caps were made from the same material and were supported by a single boiler stay.

How to Destroy a Boiler -- Part 1

Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.
