HTB-DL-WG burners are industrial-grade, direct-fired, ultra low NOx burners designed for burning difficult fuels such as copper blast furnace off gas and other waste gases with low and variable LHV (low heating value), solid particles, high moisture content and aggressive chemical compounds. In spite of very bad quality of fuels (waste fuels) the HTB-DL-WG burners require only minimal amounts of support fuel to ensure high quality and stable combustion process.
The HTB-DL-WG series burners are custom made for particular projects, but still share the same distinct features as: built-in staged burner throat, fuel injection directly into combustion chamber and utilization of preheated combustion air.
The HTB-DL-WG are designed for maximum durability, minimum maintenance and flexible control over combustion process. Typical industrial application of the HTB-DL-WG burners is copper blast furnace waste gas utilization systems co-operating with steam boiler.
The HTB-DL-WG burners incorporate proprietary combustion technology called HiTAC (High Temperature Air Combustion). It gives the burners possibility to create a specific low oxygen high temperature environment for high efficiency low emission combustion process by means of high velocity fuel and preheated air injection, intense combustion gas recirculation and voluminous diluted flame.
HTB-DL-WG Burner for direct firing operations and for waste gases recycling
Application of the HTB-DL-WG burners technology provides the following advantages:
- possibility of burning fuel with very low heating value (LHV),
- multi-fuel capability,
- flat heat flux distribution,
- flat temperature distribution,
- low emission of NOx due to lack of temperature peaks,
- possibility of decreasing fuel consumption,
- lower average temperature in the zone, due to propagation of the combustion process over large volume,
- ability to increase zone capacity, due to making possible an increase in the zone temperature,
- higher refractory lining lifetime due to lack of temperature peaks,
- low noise.
