Line burner designs with modular construction provide the most effective heat distribution for applications like gypsum board and fiber board drying. Honeywell's Linnox system uses individual burner modules, each 300mm in length, that can be assembled into lines up to 6 meters long. You select the capacity of each module—ranging from 24kW to 720kW per 300mm section—and arrange them in any sequence to create the exact heat profile your process requires. 

The integrated premix mixer thoroughly blends fuel and air before combustion, producing a uniform flame pattern across the entire burner length. This helps to eliminate hot spots and temperature variations that cause product defects. The modular approach also simplifies maintenance because you can service or replace individual sections without shutting down the entire burner assembly. Capacity ranges from 80kW/m to 2,400kW/m depending on your configuration.1

Fuel savings from heat recovery depend on your current exhaust temperature and how much you can preheat your combustion air. If your dryer exhaust runs at 1800°F and you install a heat exchanger to preheat combustion air to 800°F, you can reduce fuel consumption by nearly a quarter. Increasing the preheat temperature to 1200°F at the same exhaust temperature yields even more savings. Higher exhaust temperatures enable greater recovery. Plate-type heat exchangers typically provide better thermal effectiveness than tubular designs.1

Remote monitoring transforms reactive maintenance into proactive troubleshooting by making equipment data accessible before failures occur. 

One customer site experienced a kiln interruption that stopped the entire board production line. The new connected SLATE with Thermal IQ platform allowed the site to remotely pinpoint the issue and corporate engineering to provide system and domain expertise. This collaboration via near real-time monitoring and review of performance data allowed them to realize a solution in hours instead of days. In the past, this type of unplanned outage would cost the plant over $100,000 in lost production, scrap, and emergency plant and third-party services. 1 

The system also identifies nuisance faults and gradual performance degradation before they cause failures. Maintenance teams schedule repairs during planned downtime instead of responding to emergency shutdowns.
