Magaldi Group, founded in 1929 in Salerno, is a leading manufacturer of industrial systems and plants for bulk material handling at high temperatures in coal-fired power plants, cement industries, waste ash plants, steel plants, foundries and metal refining plants.
Magaldi Group’s mission is to design, manufacture and market reliable, high-quality systems that provide environmentally sustainable industrial solutions worldwide.
The Magaldi Ash Cooler (MAC®) is a patented system for dry extraction, air cooling and mechanical handling of bottom ash from pulverised coal-fired boilers. With hundreds of installations worldwide since the 1980s, the MAC® is the world’s leading dry bottom ash handling system for utility and industrial boilers of any size, burning any kind of fuel.
The main advantages of the MAC® can be summarised in five points:
MAR® Magaldi ash recycling is an improvement of the MAC® system for ‘dry’ extraction, cooling and handling of bottom ash from solid fuel fired boilers. That innovative process recycles both ‘dry’ bottom ash and economizer (ECO) ash in the combustion chamber, aiming at turn them into fly ash.
Dry bottom ash, along with ECO ash, can then be diverted to the MAR® system and then injected in the boiler through the coal pulverisers.
The MAP® Magaldi ash post-combustor is a development of the MAC® system to extract, convey and cool bottom ash and to enhance and control the postcombustion of unburnt particles on the steel belt in case of biomass / RDF co-combustion in pulverised coal-fired (PCF) boilers.
MAP® advantages:
The MAS® Magaldi Ash System is a patented integrated ‘dry’ mechanical system for handling all ash from solid fuel fired boilers, allowing a dependable and economical management for both fly and bottom ash.
The MAS® comprises three subsystems, as follows:
The Magaldi Ecobelt® FA is a mechanical conveyor designed for handling fly ash from the hoppers located along the flue gas path, including economiser (ECO), selective catalytic reactor (SCR), air heaters (AH) and electrostatic precipitator (ESP) or baghouse.
The Magaldi mill rejects system (MRS®) is a patented fully automatic steel-belt conveying system, designed to dry handle mill rejects from coal mills to storage silos. The system uses the reliable, high-performance Magaldi Superbelt®.
As no water is required in MRS® operations, any environmental problems associated with wet systems are avoided, as are plugging problems which may occur either in sluice or pneumatic conveying systems.
The patented Fluimac® system is an innovative system for the dry handling of bed ash from fluidised bed combustion (FBC) boilers.
The Fluimac® system is characterised by low operation and maintenance requirements and no water usage during ash processing. Using heat recovery from the ash, the Fluimac® system is also able to increase boiler efficiency.
The Magaldi Ecobelt® is the ideal conveyor for handling hot materials, aggressive chemicals, heavy or sharp products, ensuring a safe and environmental friendly operation.
The key component of the Magaldi Ecobelt® is the Magaldi Superbelt®, completely enclosed in a steel casing to prevent dust dispersion to the environment. A simple mechanical self-cleaning device removes the fine residuals from the bottom of the casing.
The Magaldi O-chain® is a chain conveyor enclosed in an independent casing, tailored around the Magaldi Ecobelt® tail section. Its function is to receive the fine residuals, taken from the Ecobelt® bottom by the self-cleaning device and to reload them onto the Magaldi Superbelt®.
The Magaldi Ecobelt® WA is a conveyor for dry extraction, cooling and handling of bottom ash produced by waste incinerators, ensuring a safe and dependable operation in an enclosed environment.
