Generally the term boiler is used for when the water
circulates through natural convection. The mass of water in
either water tube or fire tube boiler circulated naturally
releasing steam in the steam space above (fire tube) or in
the steam drum (water tube). A steam generator usually has
forced (pumped) water circulation through a series of tubes
and is kept under higher pressure to prevent steam
formation in the tubes. Ultimately, the pumped water goes
into a steam seperator where the pressure is reduced
somewhat and some of the water flashes into steam. Steam
generators can get around some jurisdictional requirements
to employ operators because they lack large drums and water
volumes and thereby are less hazardous. Because of the low
water volumes and high heat flux usually designed-in,
proper water treatment is very important.
