2015/3/17 · Step 3: Determine Blowdown Properties and Mass Flow. Using the calculated feedwater mass flow and blowdown rate: Blowdown Mass Flow = Feedwater Mass Flow * Blowdown Rate. [ Blowdown Mass Flow = 1.8 klb/hr = 18.6 klb/hr * 0.095 ] Using the Steam Property Calculator, properties are determined using Steam Pressure and Quality = 0 (Saturated Liquid).

Read MoreCombustion efficiency analysers exploit the fact that by knowing the fuel (and its chemical composition) and measuring the flue gas temperature and either the oxygen or carbon dioxide level the combustion efficiency of the boiler can be calculated. On some boilers the settings can then be adjusted to maximise the combustion efficiency. In a

Read More2021/9/13 · Boiler Efficiency Formula. The following formula is used to calculate the direct efficiency of a boiler. E = [ Q * (H-h) / (q*GCV) ] * 100. Where Q is the quantity of steam generated (kg/hr) H is the enthalpy of steam (Kcal/kg) h is the enthalpy of water (Kcal/kg) GCV is the gross calorific value of the fuel (kcal) q is the quantity of fuel (kg)

Read MoreThe Boiler Efficiency Calculator takes into account only major energy losses‚ which typically represent 10 to 20% of fuel input. The major energy losses associated with boilers fall into two categories: stack losses‚ and radiation and convection losses. Stack Losses
