Regardless of the basic process control systems being used or the fuel being burned, when working with balance draft boilers, five basic functions must be controlled: furnace draft, drum level, feed water, fuel air and steam temperature. Jerry Gilman, P.E., a retiree of Proctor & Gamble after 37 years, will present “Boiler Control Fundamentals,” a live Web seminar that teaches participants what must be controlled and how the control systems operate. The seminar will be presented Thursday, July 13, at 2 p.m. ET, via www.isa.org . Site registration is $195 for ISA members, $225 for nonmembers, allowing unlimited participants per site.
