We get things done; at least the contractors are getting it done: I'm just the score keeper - watching the budget.
Take an old Cleaver Brooks boiler - 1980- and modify it so that you have control over it. Or think of it this way. It's all about costs these days - energy costs - so ask yourself; how can I regulate - or modulate the heating loads of the campus buildings?
Instead of firing up the boiler each day to capacity and having a fixed combustion fan, a fixed flame, and a fixed psi on natural gas: you want to be able to modulate these parameters based on load demand.
Taking a 1980 Cleaver Brooks (ton?) boiler and fitting it up so that you can control it's output and input is a task for the specialists. The new controllers and gas pipe trains, the senors, probes and relays were all connected this week.
The guys in the photo were witnessing the burn in: we turned on the boiler (steam) and to run it through it's control possibilities. The digital read outs were about 80% positive; and then there's that annoying 20% of trouble signals that sent the contractor into paroxysms of angst. $$$$$$$.
By friday, it came down to some incompatible relays and the fix was on. The energy savings data is buried in the documents somewhere and maybe I can find the annual dollar rate savings.
