We just completed this system in a natural gas plant. The boilers heat 4 trane unit heater coils in the compressor building. I couldn't get pictures of the heaters we installed in it because the fireyes were on and didn't want to risk causing a blowdown . Enjoy!
We've done a few plants with similar setups. This is the first time the superhots had their own boiler controller. I actually had to remove the controllers and do some rewiring to use the tekmar 268 controller.
Another company installed the furnace system, but it's in the same room as our boilers. I hope they don't mind me posting pics of their work.
