Phil Kemp, SAACKE Combustion Services general manager, on how the company’s latest burners provide “best available techniques” in a versatile package.
Burners for industrial combustion plants must be carefully selected. In addition to the criteria of performance and reliability, keeping emission values as low as possible is important. Operators must take into account the limit values prescribed by law, similar to the BAT specifications for Large Combustion Plants (LCP). BAT stands for “best available techniques”, as described in the EU Industrial Emissions Directive.
If operators of outdated plant do not equip or retrofit them accordingly, they risk losing their operating licence. SAACKE’s answer is the latest generation of ultra-low NOx burners on the market for BAT-compliant combustion.
In the ultra-low NOx burners, the flame temperature in the flame head is reduced by recirculation of exhaust gases from the combustion chamber. This cools down the flame so that significantly less nitrogen oxides are produced compared with conventional burners. This process has no effect on the performance of the burner: on the contrary, the efficiency of the plant can even be increased.
The burners clearly comply with BAT, defined as the available techniques which are the best for preventing or minimising emissions and impacts on the environment. The aim is a reduction in NOx values for large combustion plants in relation to solid, liquid and gaseous fuels – including industrial by-products, waste materials and biomass.
As a burner specialist, SAACKE develops and designs solutions based on the individual requirements of its customers. SAACKE’s range extends from standard gas burners in “plug and play” mode to highly complex yet smart combustion systems, as well as remote plant management systems. Thanks to continuous research and development, the company offers systems both for basic industrial applications and for plants using special fuels.
The SAACKE TEMINOX GL, a further development of the established burner family, meets all the necessary criteria for a futureproof modern combustion system. The lowest emissions are below 30 mg/m3 NOx. In both the monoblock and the duoblock versions, the TEMINOX GL burns a wide range of standard fuels and special gases efficiently and with low carbon monoxide and residual oxygen content in the flue gas. The monoblock burner for gas and light oil operation achieves combustion capacities of up to 28MW with high flue gas side resistance in the flue gas system. The duoblock version can be equipped with additional air pre-heating. An optional double gas ring enables the simultaneous combustion of two different gases.
Every plant can be modernised with an advanced burner with little effort. The TEMINOX GL is used in almost all sectors, including plants for energy and heat supply, the chemical industry, food production, steel and metal production, the building materials industry and wood processing. The burner is used in shell and water tube boilers, thermal oil heaters and thermal processing plants.
The extended maximum burner capacity is between 3 MW and 28MW for gas and oil operation. In gas operation, the TEMINOX GL has a wide control range of 1:10. The compact burner is supplied ready for connection and can be flexibly configured. Its modular design allows simultaneous operation with two fuels. Other features include easy installation and commissioning as well as quick maintenance procedures, reducing plant downtime. The TEMINOX GL is therefore particularly suitable for newly constructed and retrofit plants.
In short, the SAACKE TEMINOX provides a winning combination of ultra-low NOx with increased efficiency.
