Burner - Import export

This Burner design is for use in forced draft or natural draft vertical combustors and thermal oxidisers and has a high turn-down capability. The venturi flame holder ensures that the flame remains stable under varying load conditions. The flame holder design ensures a stable gas flow around the flame and also controls the split between combustion air and cooling air in the vicinity of the burner head. EUROPEM Natural Draft and Forced Draft Burners A robust, low pressure drop burner design, used for burning waste gas and/or gaseous fuel in vertical combustors and thermal oxidisers. Can be installed as a single burner or used in a system as a central burner with additional satellite burners.

EUROPEM MultiFuel burners have a modular design to allow up to 15 waste gases and liquids to be co-combusted. The main burner body consists of a wind box with baffles. Two or three concentric central injection lances with injection nozzles are placed inside the air stream to inject the combustible liquids or gases. One or more rings with peripheral injection lances can be added for support fuel and/or to increase the number of waste gases that can be combusted. Low NOx emissions are achieved through staged combustion and a controlled flame temperature profile. Primary air is supplied through the burner wind box while secondary air is injected in the pre-combustion chamber. Axial MultiFuel Burner 1 to 20 MW capacity Long flame profile Suitable for rotary kiln and furnaces with long residence time Modular design Radial MultiFuel Burner The Radial MultiFuel Burners are equipped with a vortex control valve which enables manual control over the amount of turbulence and rotation that is given to the combustion air and the fuel/waste mixture. 1 to 20 MW capacity Control valve to control vortex and turbulence of the flame Shorter flame profile Suitable for standard fuels as well as combustion of waste gases and liquids Modular design Low CO emissions Low NOx emissions Robust design without moving parts for reliable operation Low maintenance requirements Most EUROPEM burners do not require a pre-combustion chamber or a secondary air injection chamber. This results in a shorter and hence more competitive overall combustion chamber design. Burner designs with pre-combustion chamber’s can also be furnished for specific applications.

Most of the combustion systems currently available in the market attempt to achieve their low NOx emissions combined with low CO emissions and stable combustion by employing relatively long flames, staged combustion air/fuel and with mechanical provisions near the flame to create swirl. The EUROPEM Ultra-low NOx burners use a different philosophy to achieve complete and stable combustion along with ultra-low NOx emissions: The use of thin and short flame profiles: Empirical evidence shows that narrow and short flame profiles achieve the lowest NOx emission values. Controlled flame temperatures: The flame temperature is controlled at a temperature high enough to ensure that no CO is formed whilst the temperature is low enough to avoid any NOx formation. Oxygen concentration near the flame is controlled such that the faster hydrocarbon reaction depletes all the oxygen before NOx can be formed by the slower N2 to NOx reaction. Internal flue gas recirculation: The high velocities at the burner mouth create an internal venture effect which in turn results in internal flue gas recirculation around the flame. A stable and uniform temperature profile without hot spots created in the flame will further minimize NOx formation. EUROPEM Ultra-low NOx burners are equipped with a windbox giving tangential entry of the combustion air to create a natural swirl around the flame. This principle is also employed for the waste gases entering the burner so that additional swirl is created by one or more waste gas streams. Support fuel and rich waste gas are injected through a shell type disc to obtain a narrow and short flame profile. A “tulip flame profile” or “balloon flame profile” are selected, depending on the fuel characteristics.

Europem supplies skid mounted control skid for all types of fuels and waste streams, either in combination with the burner system or as stand alone items. Skids can be supplied in accordance with national and international norms and standards. One specialty of Europem is the design and fabrication of ATEX zone 0 skids for the collection and transport of explosive vapours.

Europem has supplied a large number of specialty burners. These burners are tailored to the specific needs of the client. MultiFuel burners for waste gases and waste liquids with or without precombustion chamber, Complex waste gas burners SRU burners with high ammonia content Ammonia burners Vertical fired burners for upto 20 different waste streams, some containing high amounts of salts … Specialty burners are developed using CFD simulations in combination with burner tests at the Europem test facilties in Belgium.

The Tulip Vortex burner was developed specifically for (temperature controlled) combustors for the treatment of lean waste gases and vapours. It employs the same design philosophy as the Ultra-low NOx Tulip Vortex burners but is designed for the combustion of lean waste gases, whilst minimizing support fuel requirements. The burner creates an intense gas recirculation zone near the burner to ensure that waste gas, flue gas and combustion air are mixed. The resulting moderate flame temperature minimizes NOx formation. The homogeneous temperature profile and swirl result in complete oxidation and low CO emissions.
