Rotary Kiln Burner Design Introduction
Rotary kiln burner design involves creating burners that maximum efficiency and effectively deliver heat to the material being processed in the rotary kiln. The design must consider factors such as the type and properties of the material being processed, the desired temperature profile, fuel type and availability, emissions regulations, and energy efficiency. Various types of burners, such as swirl, axial, and tangential, may be used depending on the specific requirements of the application. Additionally, burner design often incorporates features for flame shaping, temperature control, and combustion stability to optimize the performance of the rotary kiln system.

Why AGICO CEMENT Rotary Kiln Burner
We offer advanced rotary kiln burner for cement industry with the high technology design.
Reduced Fuel Consumption and Enhanced Cement Clinker Quality
AGICO CEMENT rotary kiln burner provides maximum quality cement clinker with an excellent hydraulic activity by maintaining an ideal and controllable thermal profile. It regulates Alite crystal sizes and ensures a homogeneous distribution of clinker granulometry with a low fines rate. Moreover, the burner’s low specific fuel consumption boosts kiln thermal efficiency, preventing overheating issues and optimizing radiation. It also improves heat recuperation from the cooler due to its optimized clinker granulometry distribution. Additionally, an integrated device facilitates easy adjustment of flame shape, making the AGICO CEMENT rotary kiln burner the most fuel-flexible burner globally.
Flexible Burner Design for Cost Reduction
AGICO CEMENT rotary kiln burner is designed for easy dismantling and adjustment: once the burner momentum is set, a simple handle allows for modification of both the swirl and the flame shape while the kiln is operational. This feature prevents any disruption to the radial/axial air flows and the burner’s overall momentum. The new Cooled Heavy Duty axial tip design of the AGICO CEMENT rotary kiln burner ensures durability against heat expansion in case of refractory failure. Additionally, its intelligent technology package predicts system failures, facilitates easy maintenance, and prevents shutdowns.
Enhance Efficiency and Streamline Maintenance for Cement and Lime Production
AGICO CEMENT rotary kiln burner is an efficient, low-NOx burner designed for rotary kilns, offering high combustion efficiency and reduced operational costs. It finds applications in cement, lime, and various other mineral processing industries that utilize rotary kilns. Compared to conventional direct-fired mono-tube burners, the AGICO CEMENT rotary kiln burner achieves an average reduction in NOx emissions of 20%. It can be easily installed in existing direct firing systems without the need for equipment modifications. This innovative technology provides several benefits, including:
- Enhanced flame stability.
- Quicker ignition of pulverized coal particles.
- Decreased length of black plume.
- Burner light-up and flame detection system.
- Easy maintenance.
Design of the AGICO CEMENT High Momentum Burner
AGICO CEMENT burner operates with an external flow of primary air with high momentum, which is responsible for the slim and stable shape of the burner flame due to its high exit velocity. The primary air outflow, arranged as individual jets, promotes rapid mixing of the hot secondary air into the flame, resulting in efficient combustion. The shape of the flame is adjusted by controlling the momentum of the primary air. Swirling airflows (tangential air and dispersion air) are introduced into the coal/petcoke channel of the burner, enhancing the mixing of pulverized coal. This double-swirl design ensures flame stability and rapid flame formation, with the flame ignition point close to the burner. Compared to other burners, the flame geometry in the kiln is easily controllable, as demonstrated by the kiln shell’s thermal profile. The mixing momentum of the burner is tailored to each customer’s specific requirements, considering factors such as kiln application, system configuration, fuel composition, and clinker analysis. This customer-specific burner design, with its sophisticated nozzle geometry, has delivered excellent operational results and reduced fuel costs, even in sensitive kiln environments, such as those using white cement with a planetary cooler and a fuel mixture of petcoke and solid alternative fuels like sawdust and fluff.
