I agree that the reason for steam blowing is to dislodge slag and scale from the boiler tubes and piping. For this subject our normal approach is to select a blowing pressure and flow rate so that the 0.5*rho*vel^2 in the boiler tubes and piping during blowing is at least 1.2 times that at boiler MCR.

On some water tube boiler designs as well, the tubes are still rolled into the drums and headers. The reason for this is the fact that to weld a tube into a tubesheet or wall of a boiler drum, a complete joint penetration (CJP) weld would be required. This would mean bevelling each tube hole so only a small land of steel at the original

The fluidized bed boiler is gaining in popularity and has overtaken the grate-fired boiler in biofuel power generation applications. The principle is very simple: air is blown through a bed of sand and fuel particles at a velocity that is sufficient to suspend the particles on the airstream but not able to lift them permanently out of the bed

After leaving the cylinder, the spent steam escapes from the engine via the blast-pipe and up into the chimney in the smokebox. The action of steam in the blast-pipe creates a lower pressue in the smoke-box, and helps to draw the hot gases from the fire through the boiler tubes and in-turn generate more steam.
