High Temperature Heating Burners

Furnaces form a major part of industrial heat treatment equipment and are used in metallurgical, engineering and industrial manufacturing applications. Glass, steel, iron, aluminum, plastics, textiles, die-casting and foundry are just some of the industries that use industrial furnaces, ovens and incinerators. Metro Services, Incorporated has a burner for each of these applications.

ECLIPSE

Eclipse Model SER Single Ended Recuperative Burner

Eclipse Model SER Single Ended Recuperative burners incorporate the components of a tube firing burner system in a compact package. The SER burner is a nozzle mixing burner and recuperator coaxially mounted inside a single-ended radiant tube. Combustion air entering the SER burner is preheated in the recuperative section by exhaust gases providing higher efficiencies than stand alone burners. SER burners are available in four diameters from 3-1/4″ to 7-1/2″. Radiant tube length is tailored to the application.

Features:

  • Direct spark ignition
  • Reliable burner operation
  • Uniform tube temperature
  • Tube life comparable to conventional radiant tubes
  • Simple burner adjustment
  • Efficient ratio control
  • Multi-fuel capability
  • Type Nozzle mixing
  • Number of Sizes 4 (3.25″, 4.5″, 6″ & 7.5″ Tubes)
  • Capacity Range To 375,000 Btu/Hr (110kW)
  • Turndown 25:1
  • Process Temperature 1900°F. (1040°C.)

Bayonet-Ultra Recuperator Burner

Suitable for use with exhaust streams up to 2100°F, Bayonet-Ultra recuperators are high efficiency heat exchangers designed to fit into the exhaust leg of single, U, O, W or Trident-type radiant tubes. They’re frequently paired with ThermThief burners to provide fuel savings up to 30%.

Conventional recuperators have only one heat transfer tube. Each Bayonet-Ultra contains multiple tubes to dramatically increase the heat transfer area while significantly decreasing the amount of fuel required to maintain required heat levels. Plus, an air cooled housing cools the work area.

Features:

  • Number of Sizes: 4 (3″ thru 8″ Tubes)
  • Capacity Range: 165,000 To 325,000 Btu/Hr (48 to 95 kW)
  • Turndown: N/A
  • Process Temperature: 2100°F (1090°C)
  • Fuels: Natural Gas, propane, butane
  • Uses: Radiant tube furnaces

Eclipse Spiral Flame Burner

Eclipse Spiral Flame Burners are nozzle-mixing burners designed to produce a rapidly spinning flame that spreads out evenly over the surface of the combustion block and surrounding furnace wall with virtually no forward velocity. This permits the burner to be placed close to the work load without flame impingement.

The radiant heat from the block and wall surfaces minimizes hot spots and promotes temperature uniformity in the load.

Features:

  • Type: Nozzle mixing
  • Number of Sizes: 9
  • Capacity Range: 65,000 to 4,750,000 Btu/Hr (19 to 1392 kW)
  • Turndown: 10:1
  • Process Temperature: 2600°F (1427°C)
  • Fuels: Natural Gas, propane, butane

Eclipse Extenso-Jet Burner

Eclipse Extenso-Jet burners are nozzle-mixing medium velocity and high velocity burners with extended housings for firing kilns and furnaces with thick walls and crowns.

Extenso-Jet burners have also proven useful on special applications where it is necessary for the point of heat generation to be remote from the burner housing. A good example is the curing and preheat of the channel lining in induction melting furnaces.

Features:

  • Type: Nozzle mixing
  • Number of Sizes: 3
  • Capacity Range: 400,000 to 900,000 Btu/Hr (117 to 264 kW)
  • Process Temperature: 2350°F (1288°C)
  • Turndown: 30:1
  • Fuels: Natural Gas, propane, butane

The ThermJet Burner

The ThermJet is a nozzle-mix burner designed to fire an intense stream of hot gases through a combustor using combustion air temps up to 600°F. (315°C.)

The TJ burner comes in two types: High Velocity (HV) and Medium Velocity (MV).

The gas velocity can be as high as 500 ft/s (150 m/s) for the HV, and 250 ft/s (75 m/s)for the MV.

Features:

  • Type: Nozzle mixing
  • Number of Sizes: 10
  • Capacity Range: 155,000 to 5,000,000 Btu/Hr (44 to 1465 kW)
  • Turndown: 50:1
  • Process Temperature: 2800°F (1538°C)
  • Fuels: Natural Gas, propane, butane

The ThermThief Burner

The ThermThief’s unique nozzle creates an intense, adjustable length flame with a vigorous spinning action. The flame scrubs the inside of the fire tubes to remove the gas film boundary layer and increase heat transfer effectiveness with outstanding temperature uniformity. Not only does this contribute to longer tube life, it also ensures consistently uniform product processing.

ThermThief delivers these additional benefits:

  • Low NOx and low CO
  • Low excess air capability for high efficiency
  • Low air and gas pressure requirements
  • High heat transfer at low noise levels
  • Reliable ignition at a wide range of firing rates

Features:

  • Type: Nozzle mixing
  • Number of Sizes: 3 (3″ thru 10″ Tubes)
  • Capacity Range: 300,000 to 2,000,000 Btu/Hr (88 to 586 kW)
  • Turndown: 40:1
  • Process Temperature: 1900°F (1040°C)
  • Fuels: Natural Gas, propane, butane
