Hello

I am currently analysing past IMLEC results to try and improve the thermal design methods for small boilers. Please can anyone help with the following dimensions of the Martin Evans “Simplex” design:

Cyliner bore

Cylinder stroke

Wheel diameter

Grate length

Grate width

Firebox height

Firehole diameter

Smoketube diameter and number

Superheater flue diameter and number

Length of tubes

Working pressure psi

Safety valve bore

Many thanks in advance

Hi Martin

Bore: 11/2"

Stroke: 2 1/8"

wheels: 4 3/8" on the tread

Grate length: 5 5/8" ( distance between firebox plates)

Grate Width: 2 3/4"

Firebox Height 5 3/4" at the front, 4 5/8" at the back ( these are the dimensions of the plates, the grate sits inside slightly, reducing these a little)

Firehole : 1 1/2"

tubes: 13 x 7/16 20swg

Superheater flue: 1 x 1 1/8" 16swg

Tube length: 11 3/162

working pressure: on the drawing 110psi , (but I don't know if people run them this high?)

Safety valve: 2 x 3/16" bore

Hope this helps

Trevor
