Multiple Boiler Controllers
I am working on the design where we are putting in (3) new steel fire-tube steam boilers, each 86 boiler hp. The Owner is interested in having the successful temperature controls contractor (TCC) provide the controls and programming to stage the (3) boilers to maintain a steam header pressure and to rotate the boilers. Does anyone have an opinion on whether it is better to have the TCC provide the controls or if it is better to specify a "pre-made" mutiple boiler controller that can then tie into the building temperature controls (i.e. Heat Timer, Preferred Instruments, etc.)? My concern is that the TCC will not have the expertise to properly control the multiple boilers and have problems after startup. I would think that a "pre-made" controller has most of the bugs worked out and would be a better solution. I would like to hear your experiences of what has worked well on other projects and also what has not worked well.
