Water-tube boiler - Wikipedia
2019-8-10·A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.

Boiler Failure Due to Oversizing of Boiler feed Pump
2013-9-26·The pump discharge pressure showed 80 kg/cm2g and I found the discharge valve was almost shut. For a boiler with main steam pressure of 44 kg/cm2g, this was too high. The hand operated minimum flow valve to Deaerator was fully open. By then, I learnt that Boiler vendors commissioning engineer had set the valves as such positions.

Boiler Feed Pump Problem - Pump engineering - Eng
2007-6-4·The source of high pressure could have been a leak backward through the discharge block valve and check valve. Or, it could have been pressure from a common spill-back line to the DA if the valve on the end of that line at the DA was blocked in by mistake. But simple leakage back through the block and check would be the most likely.

2019-8-13·Fig. 4-31 shows the layout sketch of a Benson boiler. The Benson boilers are drumless type of boilers. The feed water is pumped through the economiser, radiant and convective evaporators, and superheater. The boiler pressure is maintained as critical pressure and hence water evaporates steam directly without actually boiling.

Benson Boiler - Construction, Working Principle and
Benson Boiler is a high pressure, drum less, supercritical, water tube steam boiler with forced circulation. This boiler was invented in the year 1922 by Mark Benson. This boiler is a super critical boiler in which the feed water is compressed to a supercritical pressure and this prevents the formation of bubbles in the water tube surface.
