Description

The Stackmatch DRAM Pilot is a Forced Draft Gas Fired Pilot and Ignition System designed to be operated in the most extreme atmospheres. With the Stackmatch Plasma Resonance Flame Detection and reputation for Reliable Ignition with Extreme Flame Stability, the DRAM has proven highly effective as the start-up solution for many Engineers. The DRAM design consists of two parallel and independent Forced Draft Gas Fired Pilots offering flexibility in product application. The pilot is custom sized to fit any main burner requirement and it can be constructed in a fixed or retractable configuration. Stackmatch has developed several DRAM designs for natural gas and refinery fuel applications, including the 2″ and 1 1/4″ DRAM. Each DRAM can be orifice sized for your application, allowing the DRAM to be used as the primary pilot source and at the same time effectively used as a Pre-Heater to prevent refractory damage during start-up. Ignition and start-up problems on your most difficult applications are solved by using the Stackmatch DRAM.

The Stackmatch DRAM Pilots are the only start-up solution for a Sulfur Recovery Unit ( SRU ), and are used worldwide in Pressurized Vessel and Flare applications such as Tail Gas Treatment Units ( TGTU ), Boilers, Pre-Heaters, Thermal Oxidizers, Crude Unit Burners, etc. Stackmatch Equipment provides efficiency and reliability under the toughest Fired Vessel applications in many industries including Refineries, Chemical, Petrochemical, Natural Gas Processing and Oil & Gas Plants worldwide. The Stackmatch DRAM is the industry’s only technically advanced and field proven method to start-up your processing unit. It is designed for retrofitting to most existing applications. Stackmatch advanced technology also provides increased safety while requiring less operator intervention, less down time, lower fuel consumption, maintenance reduction/simplicity and elimination of start-up delays.

Benefits of a DRAM Pilot

• Micro Flame Front Ignition providing instantaneous positive ignition.
• Plasma Resonance Flame Detection providing instant and reliable pilot flame verification for unmanned ignition.
• Cool Tip provides extreme longevity in the harshest environments.
• Instantaneous start-up time. (Both pilot sections are pre-set for variations in vessel pressure).
• No additional operator adjustments are required.
• Minimal and simple maintenance with less downtime.
• Simple installation and operator safety.

DRAM Pilot Internal Functions

• Ignition of Primary Pilot – Ignition of the DRAM Pilot is instantaneous with properly regulated Air & Gas. The Pilot operation is unaffected by wet or humid conditions. The Stackmatch Micro Flame Front Ignition method coupled with Low Voltage-High Energy Ignition 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, this primary pilot flame remains extremely stable.
• Primary Pilot Flame Detection – Using our Patented Plasma Resonance Flame Detection technology provides immediate ‘flame on’ or ‘flame off’ detection.
• Stoichiometric Tracking – All internal orifices of the DRAM are sized to automatically maintain and track the preset stoichiometric fuel ratios. Preset ratios will not change even during excessive vessel pressure swings and violent turbulence.
• Secondary Pilot Flame – Normally, the primary and secondary fuel sources are supplied by a single fuel supply system allowing the primary pilot sensor to sense the entire pilot. If your application requires it, the DRAM can be connected with a separate secondary fuel source allowing primary Pilot operation from a clean dry fuel and secondary Pilot operation using your Refinery Fuel.
• 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.
