All of About Steam Boiler, Heat Exchanger, Energy and Power Generation Maximum Allowable Working Pressure Calculation The maximum allowable working pressure (MAWP) of a steam boiler is an absolute restriction of pressure within psig unit for a steam boiler is allowed to run.
A short history of boiler designs Shell and tube-saturated steam boilers of the current packaged form have been manufactured since before the second world war, and their lineage may be traced directly back to the Cornish boilers of the early nineteenth century, invented by the British inventor and mining engineer Richard Trevithick (1771–1833).
In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred. Calculation of direct efficiency-E= [Q (H-h)/q*GCV]*100. Where, Q= Quantity of steam generated (kg/hr) H= Enthalpy of steam (Kcal/kg) h= Enthalpy of water (kcal/kg)
