THE HG-324K PROVIDES RELIABLE DATA LOGGING AND PROPORTIONAL FLOW CONTROL

The Environmental Supply Company HG-324K system is designed for sampling mercury emissions from coal-fired sources as specified in Appendix K of Part 75.  The HG-324K is controlled using an industrial data acquisition and control system with removable CompactFlash memory card for storing data files.  The HG-324K may be connected to a plant network through wi-fi or direct connection to allow program control and remote data access. Per Appendix K, dual independent flow channels are included with proportional flow control based on the CEM flow monitor or an installed pitot.  The complete system includes a dual heated probe assembly, heated sample line, dual condenser system and connecting umbilical.

HG-324K SORBENT TUBE MERCURY SAMPLER SPECIFICATIONS:

  • Rugged watertight and corrosion proof enclosure with 2” hard rubber transport wheels and retractable extension handle

  • Dual front panel flowmeters (0-1 lpm) for visual flow indication

  • Dual front panel vacuum gauges (0-30 in. Hg)

  • Dual low flow dry gas meters with digital counters for real time volume measurement

  • Dual zone temperature controller for probe heat

  • Rugged industrial automated controller includes 8 - 16 bit analog inputs, 8 analog outputs (0-10VDC), 8 - 16 bit thermocouple inputs, 8 counter inputs

  • Quick-turn Amphenol connectors for probe power, thermocouple input and external flow signal input

  • ¼” SS Quick Connectors for sample inlet and pitot DP

  • Removable CompactFlashä memory card for quick access to data files

  • Removable cartridge type acid gas sorbent protects installed equipment

  • Wi-Fi router installed for remote control and data access

  • Connect to plant network for remote control and data access

  • Program can maintain constant flow or constant proportion to stack flow per Appendix K of Part 75 Proportional flow control by external 4-20 mA signal from CEM flow monitor or dP from installed pitot

  •  Program averages and records all data at user specified intervals

  • Program may pause sampling at user defined temperature conditions

 

SPECIALIZED HG-324K MERCURY SYSTEM COMPONENTS:

  • Dual channel probes with uniformly heated zone for sorbent tubes and heated internal sample lines
  • HastelloyTM probes with compression ferrules for long term sampling
  • Heated lines in various lengths with 2 – ¼” Teflon sample lines
  • Thermoelectric condensers along with knockout impingers and silica gel impingers
