Mar 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.

Sep 12, 2019 · 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), and the thermal efficiency is 92% (non-fixed value).

Specifically, AFUE is the ratio of annual heat output of the furnace or boiler compared to the total annual fossil fuel energy consumed by a furnace or boiler. An AFUE of 90% means that 90% of the energy in the fuel becomes heat for the home and the other 10% escapes up the chimney and elsewhere. AFUE doesn't include the heat losses of the duct

An example is the gas rate measured on a Worcester Bosch 24i combi boiler at maximum output with two hot taps turned fully on: Initial meter reading = 8.436. Final meter reading = 8.524. Gas burned = 0.088 m 3 in 122 seconds . Gas rate = 3600/122 x 0.088 x 10.76 = 27.94kW gross, or 27.94/1.11 = 25.17kW net.
