Holding furnaces are used in the steel industry for the temporary storage of the liquid cast iron in order to average its chemical composition and temperature and to ensure smooth operation of the steel-making process.

 “SNT” Company (Stream-Niche Technology) provides a full range of commissioning services for the boiler on a turnkey basis. When the hearth burners are being replaced with modern SNT-type BD, our experts perform a full analysis of the boiler:

  • Analysis of the existing equipment and its condition;
  • Analysis of the existing burner during operation of the open-hearth;
  • Studying of aerodynamic flow structure of combustion products;
  • Selection of efficient equipment.

Upgrading of burners is carried out by replacement of burners using the existing schemes of the existing auxiliary equipment (air input circuit, flue gas circuit, etc.).

The client chooses the required level of automation in the selection of equipment. The minimum level of security consists of the flame ignition and control unit. When the furnace with full or semi-automation is required, it shall be set in the specifications, and then our specialists will offer the most cost-effective option for the automated control system.

Upon the completion of the upgrading, the company's specialists provide consultations to the operating personnel on the operation of the upgraded furnace in correct and efficient manner.

The vast experience of the SNT specialists demonstrates the following results after the upgrading:

  1. Burner turn down operation in the range of 10-100% and constantly high efficiency;
  2. Reduction of the specific gas consumption to 10% due to efficient fuel combustion;
  3. Reduction of gross NOx emissions;
  4. Safe boiler ignition due to the possible sustained operation of burners at 3% level of design power;
  5. Improvement of boiler safe operation by the ability to operate the burners with excess air factor from 1 to 35.
  6. Improved performance: noise abatement, ease of servicing, setup and stable operation under the variable gas pressure;

Increase of boiler turnaround time due to uniform heat load and short flame of SNT burners, which positively reflects on the lining and waterwall surfaces in its turn.
