Condensing Boilers in Primary Variable Flow Piping Systems

Webthe boiler anti-cycle timer will prevent the boiler from firing until it has timed out. Second, the system flow is reduced by the action of terminal unit 2-way valves and the secondary pump’s speed controller making the boiler primary pump’s flow rate far exceed the system flow rate at minimum load. Boiler loop flow overwhelms WebThe secondary will move more than the primary loop. It wants to move 12 GPM. As 10 GPM enters the tee from the left and the circulator starts it takes all 10 GPM the primary loop circulator will supply. As the secondary circulator starts all the water in that piping moves at the same time so it dumps 12 GPM into the tee on the primary loop. community center robinson il

Primary/Secondary-Loop vs. Primary-Loop-Only Systems

WebDec 1, 2010 · The primary loop of the P/S-loop system had its own 15-hp pump (design water flow 1,200 gpm). The long operational hours of the PLOVF system, with nearly constant flow via the pump necessary to maintain low-limit flow via the chiller evaporator, resulted in wasted electrical-energy power demand (kilowatts) and usage (kilowatt-hours). WebThe loop boiler is both used to initiate the final cooling of the ammonia-rich gas or as interstage cooling between two converters, for instance, an S-200/300 followed by an S-50 converter.
