Steam Boiler Lead Lag Control


vacuum water boiler t6

The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.


water tube steam boiler

The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.

Lead lag set-up for two steam boilers?? — Heating Help

Boiler Lead-Lag System. We use a lead-lag system for multi-boiler applications. The principal objective of lead-lag control is to ensure that the minimum number of boiler/burner units are in operation at any one time. The benefits of using lead-lag control include: Increased savings in electrical costs. Reduction in thermal stresses on the boiler.

Improving Boiler System Efficiency: Lead-Lag. 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 …
