In Reply to: Help needed for installing some meters on the boiler to monitor Efficiency. posted by MING-G on February 19, 2000 at 21:56:56:

: 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)

: : Thanks.
