the tubes/flues and not the hot combustion gases which pass through the
tubes/flues in ‘conventional’ construction. This
structure allows a higher pressure to be safely maintained in the boiler.
There are a number of thermodynamic and heat transfer improvements between a
water tube boiler operating at high pressure over the normal locomotive boilers
with the water outside the tubes/flues. <o:p></o:p></span></font></p>
