[Steam-engine] MAWP VFT vs. Horizontal Firetube

[Blake]

The only difference I can see in making calculations between the two  
is that the vertical boiler has no flat sheets other than the tube  
sheets. The locomotive boiler has flat sheets that need to be  
reinforced with staybolts, stayrods, or gussets. The flat sheets are  
inherently weaker than rounded sheets.
