In case of co-combustion (coal + biomass/RDF) or PCF boilers burning solid fuels with milling difficulties (e.g. lignite, coal boilers converted to 100% RDF or biomass), the MAP® system allows carrying on the combustion process of unburnt residues on the steel belt.
Unlike conventional wet bottom ash handling (WBAH) systems, responsible for huge water consumption, particles and fines floating in the water bath, high maintenance costs, environmental issues, and negative effects on boiler operation, the MAP® system delivers a reliable, cost-effective, and environmentally friendly operation thanks to the unique combination of the dry cooling process and the dependable Superbelt® conveying technology.
The use of the dry bottom ash handling system results in significant water and O&M cost savings. Since no water is used for bottom ash cooling and conveying, pumps, piping, and water treatment systems are no longer necessary, and the associated costs are eliminated.
Based on the specific project needs, a minimum water flow can be used to reduce dust dispersion at the discharge point. The water rate can be controlled and set during operation.
