HDS Series

HDS(X) SERIES

The HDSX is a burner that offers improved emission performance and higher turndowns (12 to 1 on Natural gas). It is based on the proven HDRV burner with a new firing head and improvements to other components to support the higher turndown and lower emissions.

The new firing head places a high spin on the combustion air that improves mixing and flame stability. This allows the burner to operate with lower NOx emissions. The firing head also is designed to keep the low fire flame off of the burner head, and allows it to operate at high turndown rates without heat damage to the firing head.

The HDS(x) series is offered from 200 to 1500 BHP. The 200 to 600 BHP range is UL/cUL listed for gas and # 2 oil.

The burner is available as a standard gas and/or oil fired burner (model HDS) and as a low NOx burner (HDSX). Both models fire natural and digester gas, LP, and #2 fuel oil as well as combination gas and oil. The HDS model is available with heavy, #4 through #6 oil ( heavy oil burners does not carry the UL/cUL listing). A long with other new feuls, such as Tallow and Bio-diesel.

The different oil systems are available on both models, a pressure atomizing return flow nozzle (to 350 hp) and an air atomizing system.

They can be equipped with linkage controls or Posi-Control (linkageless) with a wide range of options. A new fuel cam is also available.

Several low NOx options are available, using Induced Flue Gas Recirculation (IGFR). The standard offering includes 60,30, and 20 PPM NOx on natural gas. With designs available to achieve 12ppm performance.

Low NOx options are available for LP and oil firing as well.

Key Benefits

High swirl flame offers excellent flame stability for very low NOx performance
The high turbulence allows the burner to be used in smaller furnace diameters.
The field proven Purlite ignition system, the most stable pilot available.
New high efficiency combustion air fans optimize electrical needs
The IFGR system includes a shutoff valve in the FGR duct to prevent any fuel gas from re-entering the burner during the purge cycle, as recommended by UL to improve safety
Easy access to firing head, fan and FGR adjustments through access covers
New air damper that provides improved air turndown, ball bearings and adjustable opening speeds to match the fuel valves
The combustion air fan and motor are assembled as a unit, and can be removed as a unit for inspection, balancing and repair
