  • K.Boiler Master and Lead-Lag Boiler Control

    If the lead boiler approaches low fire, the lag boilers will modulate toward low fire to "help" the lead boiler and prevent a short cycle of a lag boiler. When the lead boiler leaves the high or low fire position the lag boiler(s) resume firing at the normal base load for peak efficiency.Learn More


    Lead-lag systems can measure the temperature of the water or the steam pressure in the main system and evaluate the load level. If plant production is operating heavily, the lead-lag system will bring in the secondary boilers to help spread out the load. When the lead-lag system senses that production has dropped off, it then shuts those secondary boilers down again.Learn More
