Boilers and Pressure Vessels
How boilers, pressure vessels and heat exchangers work and are put together, followed through a summer and fall with Ironbridge Industrial out of Nisku: steam and steam tables, fire-tube and packaged boilers and a greenhouse boiler retube, water-tube boilers, circulation and drum internals, HRSGs, kraft recovery and waste heat boilers, drums, headers, superheaters, economizers and safety valves, boiler erection and thermal growth, vessel shells, heads and nozzle reinforcement, tubes, tube sheets and roller expanding, TEMA shell-and-tube exchangers and air coolers, and hydrostatic, pneumatic and leak testing, ending with a capstone that retubes a refinery exchanger bundle.

What you'll learn
- Explain how boilers make steam using saturation, sensible and latent heat and steam tables, and work out heat added, efficiency and equivalent evaporation
- Describe fire-tube and packaged boilers, their trim and controls, rate them in boiler horsepower and outline a fire-tube retube
- Describe water-tube boilers, natural circulation, steam drum internals and drum level swell, and the packaged D, A and O types
- Explain how HRSGs, kraft recovery boilers and waste heat boilers recover heat, including the pinch, and recognize their typical failures and hazards
- Identify drums, headers, superheaters, attemperators, economizers, air heaters and safety valves, and the damage each is prone to
- Set and connect packaged boilers, describe the erection sequence of field-erected boilers and estimate thermal growth of top-supported boilers
- Describe pressure vessel shells, heads, nozzles, reinforcement, supports and nameplates, and compare required thicknesses of shells and heads
- Identify tube materials and sizes, tube sheet layouts and ligaments, and expand tubes to a measured wall reduction
- Name shell-and-tube exchangers by TEMA type, explain fixed, U-tube and floating head designs, and calculate duty with the LMTD
- Describe air-cooled, plate, double pipe, spiral and kettle exchangers and power plant feedwater heaters and condensers
- Plan and carry out hydrostatic, pneumatic and leak tests with correct test pressures, gauges and safeguards
- Retube a heat exchanger bundle from specification to tested bundle with complete records
