HRS-RT Burners

HRS-RT Burners (HRS Radiant Tube Burners) are ultra low NOx burners designed for indirect firing applications where flue gas can not get in contact with heating charge such as radiant tube, in processes where controlled atmosphere is required. HRS-RT burners extend tube lifetime, increase total heat transfer and reduce fuel consumption.

The HRS-RT burners are manufactured for firing output ranging from 23 kW up to 140 kW.

Series of types of the HRS-RT burners

Controlled atmosphere heating systems create specific working conditions and therefore radiant tube applications demand specific burner characteristics. So far, industrial experience has shown better energy efficiency of gas fired radiant tube burners in comparison with electrical heating systems. HRS-RT brings HiTAC technology in form of a compact regenerative burner.

HRS-RT Burner System for indirect firing heating systems

Basic working unit consists of 2 HRS-RT burners and a W-shape radiant tube. Burners swap firing/exhaust roles based on custom switching pattern. Through short burner switching time tube surface temperature attains a fairly constant, flat temperature distribution throughout its length and thermal stress is alleviated.

Example of the HRS-RT burners application


The HRS-RT burners are designed mainly for the following types of the furnaces:

  • in batch type furnaces for the following processes and metals and non-ferrous metals like aluminum and cooper:
    • heating/reheating, heat treatment, vacuum preheat,
    • austempering, intruding, non - oxidation annealing, non-oxidation normalizing, brazing, annealing, bright annealing,
    • carburizing, gas carburizing, sulphurizing & nitriding,
  • continuous type furnaces for the following process of metals:
    • heating/reheating, heat treatment, vacuum preheat,
    • continuous heat treatment, atmosphere heat treatment, bolt tempering,
    • continuous annealing, non-oxidation annealing, soot-continuous annealing, spheroidizing annealing, soot-continuous baking, non-oxidation quenching, coil tube annealing, normalizing quenching, quenching, sintering, non-oxidation normalizing,
    • continuous galvanizing, carburizing, gas carburizing, vacuum carburizing,
  • others types of the furnaces/processes:
    • electrode baking,
