: I am hoping someone can help me to find out the way of installing some meters.
: Such as Where to install the vortex flow meter so that we can measure the steam flow rate?
: How do you get the reading of the feedwater and steam (temperature and pressure)?
: What kind of devices needed to install for the feedwater?
: What kind of daily fuel BTUs we need to ask from our gas supplier?
: Is this the formula that you used for calculations Boiler efficiency?
Boiler efficiency=[Mass Flow Rate of Steam*(Enthalpy of steam-Enthalpy of Water)]/[Mass Flow Rate of Fuel*Heating Value]
: Note that we are using a Kewanee boiler which rated at 600hp (Natural gas/No.3 fuel oil)
