Read More17/3/2015 · 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.

Read MoreUsing kW and kWh, you can work out how much gas your boiler is using and therefore how much it costs. A 24 kW boiler will use 24 kWh of energy per hour. According to Choose, the cost is approximately 3.8 pence per kWh, which means it would cost around 91 pence to run a 24 kW boiler for one hour. This will change depending on the cost of gas and the

Read More20/3/2019 · Divide the BTU output by the approximate conversion factor. A natural gas burner rated at 40,000 BTUs per hour divided by 1,000 BTUs per cubic foot uses approximately 40 cubic feet of natural gas in one hour. Exact Gas Consumption. Step 1. Multiply the burner efficiency by the energy content of the gas being used.
