High temp Hot water

in THE MAIN WALL
Hello, here I am with another need of the intense inteligence of the members of the wall community.
I am covering maintenance for an industrial application. They buy hot water from a central hot water supply boiler plant. Here is my question:
The water is 375 degrees F at 275psi. There is a flow indicator on the main line coming into the boiler room that indicates 245gpm flow. The return water is varying from 230degrees to 275 degrees F. So I am seeing a temperature drop of approximately 100 - 140 degrees F. Is there anyone here that can help me determine the BTU consumption of this boiler room? Or show me to a source that I could go to find the formula(s) needed for this calculation?
AS always thanks
BTW lots of "dead man" sized pipes in this boiler room.

    the formula comes from this one...

    BTUH / (8.3 x 60 x TD) = GPM

    flipped around, I think it reads

    BTUH = 8.3 x 60 x TD x GPM

    BTUH = 498 x 100 x 245
    to 498 x 140 x 245

    or 12,201,000 to 17,081,400 BTUH

    Sound right?
