Reliable technology for biomass
Effectively handling high-temperature boiler ash. Cost-effective production of energy biomass is very much dependent on efficient handling of available biomass sources, as well as the efficiency of each process. Combusting biomass in a boiler generates ash with high temperatures. This ash (either bottom or fly ash) needs to be cooled and/or processed to a form that can be transported from the power plant.
Ash handling optimization . Bag Ash filter. A high performance bag filter is an easy step toward reducing pressure loss. The optimized design has been deployed in numerous DP projects and is compatible for all DP equipment. Cyclone / Spark Dust separator. The handling of dust sparks has been improved through a simplified structure which is
Packaged biomass energy systems incorporate a fuel feed system, ash handling system, and electric automation controls. Installation supervision, training, parts, and equipment service management are provided to help maintain and support efficient operation for the life of the system.
The Renewable Heat Incentive scandal (RHI scandal), also referred to as RHIgate and the Cash for Ash scandal, is a political scandal in Northern Ireland that centres on a failed renewable energy (wood pellet burning) incentive scheme that has been reported to potentially cost the public purse almost £500 million.

Learn more about HURST Biomass Boiler Systems and see models and plan views, click here. Elimination of Biomass Emissions. Generally speaking, the combustion of biomass material produces emissions that can prove to be undesirable. Maintenance is typically also an issue with regular tube-cleaning and ash removal.
ash contained in biomass has consequences on the handling and the utilisation/disposal of ash residues from biomass combustion plants, and of the mixed ash residues from the co-firing of biomass in coal-fired boilers. Ash related problems when cofiring biomass with coal in PF burners - Rob Korbee, ECN, Netherlands
Feb 02, 2015 · Many power boilers burn solid fuels, such as wood residue (biomass) and coal, which produce large amounts of ash that must be handled and disposed of. Each solid fuel boiler has a specially
The effect of biomass ash on the performance of flue-gas cleaning equipment. – The handling, utilisation and disposal of ash residues from biomass combustion plants and mixed ash residues from the co-firing of biomass in coal-fired boilers.
The boilers come with controls that permit automatic ash discharge and fuel feeding. The intelligent control systems maintain the operation levels at optimal levels for efficient combustion and low wear rates. Cleaning of the convection tube package and ash handling are carried out automatically with programmed intervals.
biomass . Ash is an integral part of the plant structure and consists of a wide range of elements . In wood, ash represents less than 2 percent, while in agricultural crop materials it can be 5%–10% and up to 30%–40% in rice husks and milfoil. Biomass-based products produce solid residue ash, a result of thermochemical degradation. These
