Firetube Boilers

In a scotch boiler, the furnace is a large diameter tube, within the boiler, surrounded by water. Some older, large scotch boilers had two or three furnaces but modern boilers typically have only one. Scotch boilers may be two-pass, three-pass, or four-pass depending upon the arrangement of baffles and tubes.

Calculating Boiler Efficiency - Forbes Marshall

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. Q= Quantity of steam generated (kg/hr) H= Enthalpy of steam (Kcal/kg) h= Enthalpy of water (kcal/kg)
