Selas Superflame™ Low NOx Medium & High Velocity Burners

The burner’s outer tube is made of advanced silicon carbide and the inner firing tube is made of stainless steel alloy. The high velocity burner incorporates two-stage combustion for low NOx. Specifically designed nozzles provide cool NOx-inhibiting first stage combustion. Final combustion occurs in the second stage area where combustion products exit at velocities of over 275fps (83mps) for medium velocity and 400fps (122mps) for high velocity.

Superflame combustion produces heat in dense loads and circulates the furnace for thorough heat uniformity enabling faster heat uniformity.  Superflame medium and High Velocity burners function well with ambient or preheated combustion air up to 700°F (371°C). Durable, lightweight SiC firing tubes are self-supporting.

The burners are ideal for installation in either brick or fiber wall furnaces, and are easily mounted to the furnace. The Superflame low NOx burner will work with ultraviolet detectors and most sizes also accept flame rod. Direct spark allows flexibility in designing the control system.

Rugged Construction for Optimal Performance
The new ERB QuadCool surface modification burner features anodized aluminum construction with internal cooling tubes on 4 sides and flow in any direction. Heat deflection is minimized to an industry leading <1/16”, achieving near perfect parallel energy distribution across any substrate. QuadCool will remain parallel to all backup rolls to within 0.002”, even during high temperature operation.

Engineered for Simple Retrofit, Replacement and Maintenance
Drop-in replacement ribbon packs make cleaning maintenance and BTU output changes fast and easy while the burner is still mounted on the machine. A wide variety of ribbon packs are available, making the QuadCool very versatile for any 2D application. With available quick disconnect water and fuel connections, removing the burner takes only seconds rather than minutes or hours. Manufactured from anodized aluminum, the QuadCool is available in any length up to 3.5m (140”).

Selas Refrak™ Screen Burners

Two Models For Superior Combustion Control For Furnace Temperatures Up To 2100°F and Over 2100°F

The Selas Refrak Screen burner is a sealed-in tunnel burner with superior flame retention and combustion characteristics. The RSA’s large perforated refractory screen distributes the air/gas fuel mixture uniformly within the tunnel and assures complete combustion over an extremely wide throttling range. The Refrak Screen Burner has many advantages such as a wide operating range, low operating pressure, complete combustion, easy installation, easy replacement, low velocity and short flame.

Selas offers two kinds of Refrak Screen burners. Burners for furnace temperatures up to 2100°F are available in eight standard sizes for capacities up to 4,000,000 Btu/hr and for wall thicknesses from 6 3⁄4″ to 12 1⁄2″. Burners for furnace temperatures above 2100°F are available in 11 sizes fabricated to specific wall thickness.

S123 Refrak Screen Burners are recommended where furnace temperatures exceed 2100°F. Employing the same refractory port system as the RSA series, S123 burners maintain the same operating characteristics. Because of the higher temperatures encountered, however, it is not practical to offer the piloting and safety accessories available with RSA equipment.

S123 Burners are produced in a wide range of sizes and are fabricated to specific wall thickness. Easy to install and maintain, they provide an economical answer to high temperature requirements. Maximum operating temperature remains a function of furnace design, operating cycle, and turndown requirements.

Pyronics® Balanced Regulator BZR

The BZR regulator series is available for precise control of ambient temperatures up to a continuous operating range of 150° F (Model BZR-150). For heated gases or higher ambient operating conditions, models BZR-300, BZR-500 and BZR-700 are available.

Pyronics Model BZR-B uses a gas adjuster downstream of a negative biased regulator, so high fire can be set to stoichiometric conditions. As the system is turned down, the spring bias will subtract from the combustion air pressure causing the burner to go lean. Model BZR-B-300 is available for up to 300° F service.

The Pyronics Gas-Lok is a modification of the Zero Governor enabling its use as both a precision balanced regulator and operating shutoff valve.

Red-Ray® Redi Pak

Redi-Pak has a self contained blower, mixer and controls to light and monitor premix burners. It was developed as a safe, easy to set up and use system. This unique product was granted US Patent #8,105,077.

The Redi-Pak operating and control unit is an easy and cost effective way to add premix infrared gas heat to an oven. It is available in two sizes, 150,000 btu/hr and 400,000 btu/hr and can fire single burners or dual burners. Remote control is available on single burner models.

Performance
  • Operates a variety of burner types
  • Manual or remote start and modulation
  • Ignition & programmed automatic relighting
  • Constant flame supervision with LED indicator: If the flame signal is lost once the burner is running, the ignition control will immediately spark for up to 15 seconds to try to regain the flame signal. If the flame signal is not regained, the gas valve will shut which turns off the burner. The Redi-Pak continues to run the blower at the MAXIMUM setting. The Flame Failure LED indicator will illuminate, the Alarm Relay will energize and the Redi-Pak will remain in LOCKOUT until power is cycled off and on.
Design
  • Quiet Operation
  • Factory set for specific burner model and size
  • Pre-programmed solid state controls
  • E-stop for safety
  • Capable to add additional interlocks with LED indicator: The User Interlock input is an optional input located on a terminal block within the control box.
  • U.S. Patent # 8,105,077
Cost Saving
  • Fraction of the cost of non-packaged components
  • Simple to install in new systems
  • Easy to add to existing systems
Maintenance
  • Internal air filter with easy access door: The air intake tube on the back of the Redi-Pak unit leads to the filter compartment. An air conduit can be attached here to bring in clean air from a remote area. Particulates will clog the filter over time and starve the combustion air to the burners which reduces their output. The filter should be cleaned or replaced when necessary.
  • Filter pressure drop monitoring with LED indication when change needed: The Clogged Filter pressure switch is factory installed on the Redi-Pak unit. The Air Filter LED indicator illuminates to signify that the Redi-Pak filter needs to be cleaned or replaced. This does not prevent the burner from starting or running, but is for maintenance purposes only. A clogged filter will reduce the pressure input to the burner and thereby reduce its maximum output.
  • Mounting bracket ready for top, back or side mounting.

Selas Qual-O-Rimeter® (QOR)

QUAL-O-RIMETER® Monitors And Adjusts Fuel Gas Quality
For industrial service where changes in fuel gas or ambient air characteristics will upset the heating process, the mixture output from the combustion controller can be monitored and controlled. The Selas Qual-O-Rimeter Mixture Monitor detects any deviation in flame temperature and automatically adjusts the gas/air ratio to compensate. By connecting the Qual-O-Rimeter sample line immediately downstream of the combustion controller, continuous and accurate correction for gas and ambient air variations is assured before production is affected.

The Selas Qual-O-Rimeter Mixture Monitor is superior to oxygen analyzers for temperature-sensitive processes. Pushbutton control, digital display, and microprocessor circuitry assure easy operation and fast-acting response. Built-in alarms and an output for optional recorder are also included.

Two models are available from Selas to handle either raw gas or complete mix of air/gas premixing systems. Click on one of the links on the right side of this page to read more about them.

Selas CAV

Selas Combustion Controllers are precision premix systems for blending fuel gas and air. They are suitable for most fuels, mixing them with room air and compressing the mixture to deliver a precise, preset gas/air ratio at uniform pressure to the burners. Selas combustion controllers are available with two valve types:

  • Posimix® valves for applications requiring constant heat
  • CAV valves for processes requiring variable heating
The Posimix valve is used in positive displacement (Model PM) compressor and centrifugal blower (Model TD) combustion control systems. Depending on the valve size, from B to F, and compressor/blower rating, these combustion controllers will provide a wide range of mixing capacities from 2,000 SCFH to 150,000 SCFH.

The CAV valve is used in positive displacement (Model CA) type and centrifugal blower (Model TD) combustion control systems, to deliver optimum turndown range in capacities from 500 SCFH to 125,000 SCFH, depending on the valve size, 5 to 150, and the compressor/blower rating.

In either case, the precise combination of compressor/blower and valve selections also depend on other variables, such as the job type, the sea level elevation, the pressure and the capacity. A Selas applications engineer can make the best recommendation to deliver optimum performance.
