Industrial Burner for Gas RTIndustrial Radiant Tube Burner for Gas RT

The RT series are gas burners used for radiant tube systems (indirect heating). Radiant tube systems use heat radiation to provide heat transfer to work inside a furnace without risk of flame impingement or contamination of the work by products of combustion. The radiant tube is connected to the burner. Radiant tubes can have different shapes, resembling letters of the alphabet. The most common are: I, U, W, M, P, and Double P.

The RT series is not self-recuperative, but a plug-in recuperator is available. RT burners can be used with preheated air up to 930°F.

Characteristics:

  • Available in 100K to 1MM Btu/hr capacities
  • Flow ratio = 4:1
  • For use with preheated air up to 930°F
  • Excellent flame stability with: excess air, excess of stoichiometric combustion gas

Applications:

  • Tanks immersed at high temperatures in salt bath furnaces or in the melting of light alloys
  • Quenching furnaces
  • Bell or pit furnaces
  • Furnaces for processing ferrous, synthetic material, glass, and porcelain
  • Furnaces for food processing

Description

The main characteristic of the RT burner is double air mixing. The primary air is mixed in the crossflow head resulting in a twisting flame; the secondary air, which enters the chamber through special holes in the flame arrester pipe, completes the mixing by extending the flame itself. Thus, double air mixing ensures less wear of the initial part of the radiant tube, which normally sees the most stress, and allows the maximum heat exchange. The result is higher efficiency and longer life of the radiant tube.

Setup of the RT series of burners is simplified by pressure taps that allow the identification of gas and air flow rates. The volumetric air/gas ratios normally used in radiant tubes burners are 12:1 or 13:1. The RT series can work with cold air and, using special smooth or finned exchangers, with preheated air up to 930°F, allowing energy savings of around 25-30%.
