Hydrogen DRAM

Category: Forced Draft Pilots

The Stackmatch Hydrogen DRAM Pilot is the pilot necessary for gas compositions made primarily of Hydrogen. Stackmatch has designed this pilot to run on hydrogen and air to start any burner application. With the same principals of the original DRAM, the Hydrogen DRAM runs as effortlessly and efficiently as any other Stackmatch Pilot.

Description

The Stackmatch Hydrogen DRAM Pilot is the pilot necessary for gas compositions made primarily of Hydrogen. Stackmatch has designed this pilot to run on hydrogen and air to start any burner application. With the same principles of the original DRAM, the Hydrogen DRAM runs as effortlessly and efficiently as any other Stackmatch Pilot.

The Hydrogen DRAM is custom-sized to fit any burner requirement and can be constructed in a fixed or retractable configuration. Construction of the pilot is all stainless steel and can hold up to the most inert, corrosive atmospheres. Because of the excessive heat generated by the hydrogen fuel, Plasma Resonance Flame Detection is not offered with the Hydrogen DRAM Pilot. Your existing visual flame detection will suffice. Even though the Hydrogen DRAM lacks flame detection, it still incorporates Stackmatch’s reliable ignition and extreme flame stability. Our advanced technology also provides increased safety while requiring less operator intervention, less downtime, lower fuel consumption, maintenance reduction and elimination of start-up delays.

Benefits of the Hydrogen DRAM

  • Micro Flame Front Ignition provides instantaneous positive ignition.
  • Quick start-up time.
  • Pilot is pre-set for variations in vessel pressure.
  • No additional operator adjustments are required.
  • Minimal maintenance.
  • Small footprint for easy installation.
  • Safer for System operator.

Mechanical Features

  • Flange sized to customer specification.
  • Requires a 2″ diameter or larger opening.
  • Constructed to customer applications length.
  • Operates from 88% to 100% Hydrogen fuel source.
  • Gas and Air inlets are 1/2″ NPT.
  • Normal gas and air pressure is set at 30 PSI unless specified otherwise.
  • Electrical options are 110 or 220 @ 50-60 Hz.
  • Uses less than 1 amp for continuous service.

Internal Functions

  • Ignition of Pilot – Ignition of the Hydrogen DRAM Pilot is instantaneous with properly regulated air and gas. Pilot operation is unaffected by wet or humid conditions. The Stackmatch Micro Flame Front Ignition method, coupled with Low Voltage-High Energy igniter, generates a fireball within the pilot that travels forward to shower the primary nozzle with flame for assured nozzle ignition. Protected internally from external turbulence, the pilot flame remains extremely stable.
  • Stoichiometric Tracking – All internal orifices of the Hydrogen Dram are sized to automatically maintain and track the preset stoichiometric fuel ratios. Even during excessive vessel pressure swings and violent turbulence, the preset ratios will not change.
  • Electronics – Stackmatch Control Systems are designed to operate on voltages based on your power source, including AC or DC, and can be provided in either explosion-proof or non-explosion-proof configurations.

Our Patented Technologies

Flame Detection

Plasma Resonance is a Stackmatch Patented method of flame detection specifically designed for instantaneous pilot flame recognition and when unavoidable, to fail in the fail safe condition.

Micro Flame Front Ignition

Stackmatch Pilots operate with our patented Micro Flame Front Ignition technology that is built with an ignition tube located inside the pilot body. This tube is allowed to fill with the same volatile fuel normally processed through the pilot body.

Cool Tip

With top and bottom diversion plates, it’s designed to allow the spent nozzle gas to continuously clean the pilot nozzle. As the spent gas escapes to atmosphere, this downward jetting action further protects the nozzle cavity from contamination.
