MAS Kiln Burner Catalogue

Product catalog summary

Introduction to Secondary Fuels: The integration of secondary waste fuels in kiln burners necessitates evaluating technical feasibility, economic conditions, legal regulations, and the investment-to-benefit ratio. These factors impact the chemical process, fuel quality, cost savings, and adherence to environmental standards.

Liquid Secondary Waste Fuels: Specialized oil lances like the UNIGRESS DDM-X are used for firing liquid waste fuels, accommodating various viscosities and solid components for efficient combustion and maintenance.

Solid Secondary Waste Fuels: Solid waste fuels are optimally fired using pneumatic conveyance through the kiln burner. The Pneumo-Swirl technique ensures complete combustion, considering load factor, medium velocity, particle sizes, and air flow.

Equipment Specifications: Specifications include standard pipe dimensions and specific air and waste flow rates. The UNIGRESS ZL oil lance offers advanced control for efficient burner operation without nozzle changes.

Waste Oil Lance UNIGRESS DDM/X: Designed for burning liquid waste fuels with compressed air or steam atomization, accommodating high or low viscosity fuels and solid particles with low wear and pressure losses.

Burner Automation: The Unitherm M.A.S.-burner can be automated for enhanced control and efficiency, allowing remote operation and integration with burner management systems.

Divisible Burner Jacket Tube: This option facilitates easier maintenance and cost savings by allowing partial removal for relining, reducing space and inventory costs.

Extension of Burner Refractory Life: Solutions like cast-ribs and ceramic bricks reduce thermal stress and abrasion, with kiln condition analysis necessary for appropriate design selection.

Pneumo-Swirl Device: Enhances solid waste fuel combustion by inducing rotational flow, adjustable for flame length and burnout time, integrated into the burner's primary air system.

Calciner Burners: UNICAL calciner burners support both traditional and alternative fuels, accommodating various performance ranges and fuel types.

Fuel Types and Applications: Fuels such as coal, petcoke, and natural gas are used in cement production, with systems ranging from 60 MW to 165 MW.

Top Fired Calciner: Designed for optimal fuel distribution and complete combustion, focusing on good mixing, retention time, and low NOx emissions.

Hot Gas Generators: Unitherm Cemcon designs hot gas generators for direct air heating, available in HG (350°C – 1,300°C) and HR (100°C – 350°C) types, with varying performance ranges and fuel types.

Fuel Supply Systems: Include unloading pump stations, pressure reducing stations, and burner regulating valve trains for efficient fuel supply in kiln and calciner operations.

Burner Management Systems (BMS): Optimizes burner and kiln operations, ensuring safety and flexibility, designed according to VDE and EN regulations with remote and local operation capabilities.

Thermal Oil Boilers: Designed for fuel oil preheating in the cement and lime industry, offering low emissions and minimal maintenance, operating up to 300°C with capacities from 500 kW to 10,000 kW.

Spares & Maintenance: M.A.S.-burners are low maintenance, featuring threaded fuel nozzles and high heat-resistant materials, allowing maintenance by plant personnel without specialist intervention.
