Thermax offers single-drum and bi-drum type blast furnace gas (BFG)/lean gas fired boilers* for the steel industry. Both packaged and site-erected options are available. The burners for these boilers are manufactured indigenously. A notable benefit of Thermax's proven design, effective at over two dozen operating installations, is its high reliability in spite of the peculiar characteristics of the gas-slow-burning nature, low calorific value and low combustibles.

  • Change-over to oil firing in case of interruption of BFG supply
  • Refractory-lined furnace for stable combustion; scroll burner for high mixing energy of air and BFG, ensuring efficient combustion
