Retubing small fire tube boiler - Practical Machini

Dec 30, 2016· This is a little boiler I picked up intending to use it with the "Virginia City" steam engine Post Civil War small Box Bed Steam Engine. It is very small..12" diameter with an overall fire tube length of aprox 24" ( from tube sheet to tube sheet ) I have removed the leaking flues and the rest of the boiler looks pretty good although as an added precaution I am having it tested ultrasonically.

Firetube Boiler Design, Construction & Engineeri

Summary. •The firetube boiler is a versatile package suitable for a plethora of applications including heating and process. •Typical size range is 100 –2500 HP. •Pressures to 350#. •Construction follows ASME code Sections I & IV and includes close 3rdparty inspections. •There are both dryback & wetback horizontal firetubes with each having advantages and disadvantages.
