Boiler Specs for OY vs K28:

OY K28
Barrel Dia. 59" 63"
Flue length 9'6" 16'
2" tube # 120 -
2-1/4" tube # - 106
5-1/2" flue # 18 22
firebox length 92" 72"
firebox width 50" 60"
heating surface 970 sq ft. 1600 sq ft.
superheat surface 192 sq. ft. 396 sq. ft.
grate area 32 sq. ft. 30 sq. ft.

I don't have OY's firebox depth, but I remember being inside it and standing upright on the grates, it's at least 70". A K-28 has a sloping grates that start 44" from the crown at the door and slope to 60" at the tube sheet.

In short nothing matches between the two. OY has a short fat boiler with a long deep firebox, and short flues compared to a K28.

OY does have the same cylinder size as a K27 though (17 X 22).
