Low-Pressure Operation

Industrial boilers and process heaters operate at low fuel pressures after final regulation typically 5-50 psig. LP scrubbers positioned after pressure reduction remove contaminants accumulated during transmission and distribution preventing burner nozzle plugging, flame instability, and equipment fouling while maintaining minimal pressure drop.

Vessel Design

Vertical or horizontal configuration with basket strainer removing large debris, cartridge filters capturing particles above 10-25 microns, coalescing section separating liquid droplets, and outlet mist eliminator. Lightweight construction suitable for low-pressure service. ERGIL sizes scrubbers based on fuel flow rate and burner requirements with typical capacities 1,000-50,000 SCFH.

Filtration Technology

Basket screens provide coarse filtration protecting downstream elements. Pleated cartridge filters capture rust, scale, and solid particles. Coalescing media removes condensed hydrocarbons and compressor oil preventing liquid carryover to burners. Replaceable elements enable simple maintenance without specialized tools.

Material Selection

Carbon steel or aluminum construction suitable for low-pressure natural gas service. Materials rated for operating conditions 5-150 psig and temperatures -20°C to 60°C. Quick-opening covers enable element access. Design per ASME Section VIII or industrial pressure vessel standards.

Applications

Industrial boiler fuel conditioning, process heater and furnace fuel cleaning, kiln and dryer burner fuel treatment, package boiler fuel supply, and commercial heating systems. Serves manufacturing, food processing, chemical plants, and facilities requiring clean low-pressure fuel gas.

Control Features

Differential pressure gauges indicate filter loading requiring maintenance. Manual or automatic liquid drains remove accumulated condensate. Simple instrumentation suits industrial boiler room environments. Low maintenance requirements with visual monitoring.

Performance Benefits

Protects burner nozzles and control valves from plugging extending equipment life. Maintains combustion efficiency through clean fuel delivery. Prevents unplanned shutdowns from fuel quality issues. Low-cost filtration with readily available replacement elements. Minimal pressure drop preserves burner operating pressure.
