The boiler gas consumption calculation need the following parameters: such as natural gas calorific value 8500kcal/m3 pressure 8-10Kpa and theoretically the gas consumption of boiler heat = boiler calorific value÷(Calorific value of natural gas x Boiler thermal efficiency )= 2400 000 Kcal / (8500Kcal * 0.94) =297m3/

Learn MoreSep 12 2019 · How to calculate the gas consumption of a gas boiler? 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 600000 kcal (fixed value) the natural gas calorific value is 36.22 MJ/Nm3 (fixed value) and the thermal efficiency is 92% (non-fixed value).

Learn MoreBoiler Efficiency Calculators Boilers and steam systems consume large amounts of energy and may present an opportunity for significant cost savings. See the "About This Calculator" tab to get started on this savings.

Learn MoreMar 17 2015 · Steam Boiler and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Learn MoreTo calculate or check the right boiler size for a definite building without using the rule of thumb there are various gas boiler size calculators available online. They all can assist. Your task is to choose the one the suits the needs you have. Examples of online

Learn MoreJan 09 2017 · In that case your are basically looking for an efficiency calculation. Since this will vary greatly by boiler design and quality you will need to measure it empirically. Kw of heat out/ Kw of gas input = efficiency. Lets say you calculate it at 1 minute and 5 minutes from start. For 0 to 1 minute you multiply 1 minute x (1 - efficency) x gas flow.
