The main point is that RFG generated by the FCCU and the Alkylation Unit is piped to the Wickes boiler, and steam from the boiler is piped to the FCCU and Alkylation Unit; the Wickes boiler is therefore one of a "group of vessels which are interconnected," 29 C.F.R. § 1910.119(b), and therefore covered as part of a "process" by the PSM

The scope of the question is a bit foggybut i'll take a stab at answering it. "Modulation" refers to the fact that the boiler "modulates" the flame by a variable gas valve and varying the blower speed. This allows the boiler to adjust its flame (or BTU input) as it reaches a target supply temperature.
