The transient calculation results are given through the steam boiler thermal hydraulic parameters such as drum water level, pressure, temperatures, void fraction and mass flow rates. During the steady state operation of the boiler (−100 s to 0 s), steam and feedwater flow rates are equal to 374 tons/h.
Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate. This results in very high steam release rates per unit of water area, and turbulence. Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam.

A back pressure steam cycle works as follows. The boiler produces 8 kg/s of steam at 40 bar and 500oC. This is expanded to 2 bar with an isentropic efficiency of 0.88. The pump is supplied with feed water at 0.5 bar and 30oC and delivers it to the boiler at 31oC and 40 bar. Calculate the net power output of the cycle. (Answer 5.24 MW)
The standard cold water operating pressure of most U.S. and Canadian hot water boilers is 12 pounds per square inch (psi). If the boiler pressure drops below 12 psi, the valve will allow new water into the unit to bring up the pressure reading.
(c) A boiler produces superheated steam at 40 bar and 350°C from feedwater at 30°C. The higher heating value (calorific value) of the fuel is 45 MJ kg-1 and the heat from each kg of fuel generates 13.1 kg of steam. Calculate the boiler efficiency based on the higher calorific value of the fuel.

A steam boiler is a closed vessel, generally made of steel, in which water is heated by some source of heat produced by combustion of fuel and ultimately to generate steam.
better results in boiler water treatment (i.e., cleaner boilers). The important key to success is to use the same care in selecting, applying, and controlling the treatment program. Chelating programs are another variation of water treatment. The word chelate derives from the Greek word chele, meaning claw. This was probably chosen because of the
