Parker Boiler Premix Burner System
The Parker Boiler System consists of a burner bed of Heavy Duty Metal Fiber Burners (MFB). Through a gas/air premix manifold, the burners may be linked to a fully modulating blower mixer which offers precise control of combustion through the full range of modulation. Parker Boiler uses a variety of premix gas/air mixing & delivery systems for it's "L" System boilers. Parker Boiler's Low NOx Systems are typically designed for a 20 or 30 ppm level at 3% O2, however, special lower Low NOx boilers are available.In all cases, a Premixed gas/air is distributed to the burners by a manifold. By precisely controlling the gas/air ratio provided to the burners, Low NOx emission & efficient clean combustion is obtained.

Low NOx Hot Water Boiler With Internal Reclaimer Insert ("LR" Model)
Unlike Conventional Power Burner Technology, the burner bed provides a uniform heat distribution on all boiler tubes for improved heat transfer and boiler efficiency. Uniform heat over the entire heating surface at high, low and modulating firing rates provides longer tube life by eliminating concentrated firing on limited tube surface.
High Efficiency “LR” models incorporate a built in finned steel tube bundle in addition to the standard tubes. These heavy duty finned tubes are placed above the standard Parker Boiler tubes, and they significantly increase the amount of heat absorbed from the flue gases, thus increasing boiler efficiency. With the additional heating surface, the already long Parker Boiler Hot Water Boiler life is extended even further. The efficiency ranges from 83 to 85%.
NOTE: All drawing dimensions should be verified prior to installation. Due to continuous improvements and irregularities of purchased structural shapes and rounding, dimensions may vary and are subject to change without notice.If the model of the boiler you are looking for is not readily available here please contact Parker Boiler for more assistance at (323) 727-9800 from 8:00AM to 5:00PM (PST).
