For jackshaft boilers with single-point positioning of fuel and air. Includes interface to new or existing burner management system. TrimPAK For single- or dual-fuel boilers, provides parallel po-sitioning of fuel and air with O2 trim. An easy way to improve on jackshaft controls for greater efﬁ ciency and safety.
In a traditional parallel position system, there are two actuators: one for the fuel and one for the air. They are adjusted simultaneously by the same controller output, based on demand. Measurement of excess oxygen is provided for automatic fuel/air ratio trim. Flue gas recirculation is shown for low NOx burners. This is a safer and more efficient method for boiler control than jackshaft control alone.

Apr 24, 2019 · Tune the boiler when it is hot. A cold boiler will throw off actual operating O2 and CO readings. Parallel positioning systems with integrated flame management. This allows old technologies to be as efficient as they can be. Replacing linkage arms with servo motors on the fuel metering valve and combustion air damper.
Single-Point Positioning Control In most boilers, a fuel valve regulates fuel to the burner and a combustion air damper regulates combustion air to the burner. The fuel valve is typically controlled by signals from the boiler’s steam or hot water gauge and modulates based on heating demand. In single-point
The Cleaver-Brooks Fuel Air Ratio Control System is a microprocessor-based parallel positioning combustion control system.
