Jul 07, 2017 · Whether you're ready for a new boiler installation or just wondering how often to service your current model, the topic of boilers can be a confusing one. It can be tough trying to make sure you're buying the correct boiler for your home, or deciding whether your boiler can be repaired or not. That's why we've put together this list of commonly asked questions about boilers.

Gas consumption = Gas boiler power /Fuel calorific value / Gas boiler heat value utilization. For example, we operate 1 ton gas boiler for 1 hour (full load). The boiler output is 600,000 kcal (fixed value), the natural gas calorific value is 36.22 MJ/Nm3 (fixed value), …

i. Evaluation of boiler efficiency: By direct method Boiler efficiency (%) : q GCV Q (H h) 100 × × − × Q = Quantity of steam generation per hour : 7000 kg/h q = Quantity of fuel used per hour : 600 x 0.89 = 534 kg/h GCV = Gross calorific value of the fuel : 9650 kcal/kg H = Enthalpy of steam (kcal/kg) : 665 kcal/kg

Mar 17, 2015 · Boiler Energy = Steam Energy Flow + Blowdown Energy Flow - Feedwater Energy Flow; Step 5: Determine Fuel Energy. Fuel Energy = Boiler Energy / Combustion Efficiency; Assumptions. Deaerator provides feedwater near the boiling temperature for the deaerator's set operating pressure. (Saturated Liquid) Steam, Boiler, and Blowdown Pressure are the same.
