Vertical Water Tube Boiler: Flow Animation and Assumption Calculator
Explore a water-tube circulation diagram and calculate flows from entered steam rate and multipliers. The pressure marker is arithmetic only, never a relief setting.
Cylindrical Double Flue Boiler Mechanism: How It Works, Parts, Formula and Industrial Uses Explained
Follow the Lancashire boiler’s twin furnace tubes and external gas passes. Estimate useful heat and steam flow from fuel energy, efficiency and enthalpy rise.
Worthington Boiler Mechanism: How the Horizontal Return Fire-Tube Boiler Works, Parts and Uses
Explore a horizontal fire-tube boiler schematic and tube surface area. The heat-to-steam and scale results are hypothetical comparisons, not operating predictions.
Wheeler Vertical Tube Boiler Mechanism: How It Works, Parts, Diagram, and Steam Calculator
Compare vertical-tube surface area and assumed heat input. The evaporation estimate uses an approximate latent heat and does not rate a boiler.
Sterling Boiler Mechanism: How a Bent-Tube Stirling Water-Tube Boiler Works, Parts and Diagram
Stirling boiler explained — how the bent-tube water-tube design works, why power stations adopted it, sizing formulas, and real heritage and industrial applications.
Harrison Boiler: Sectional Spheres and Geometry Calculator | FIRGELLI
Explore the Harrison sectional boiler and ideal sphere stress, pressure thrust, outer area and internal capacity. The calculator does not establish a boiler rating.
