The DP UltraMulti is the latest enhanced core product in DP’s extensive product range. It is an ‘Ultra’ High Pressure, High Temperature boiler that is designed to combust single or multiple fuel types to extremely high efficiencies. The existing HPHT standards can efficiently combust ‘soft’ or ‘hard’ fuel types but this can be further enhanced by additional pressure parameters. The DP UltraMulti increases the pressure parameters and with the addition of a corresponding Ultra High Pressure turbine, raises the efficiency levels even further. The parameters have been defined by many years of operating experience and extensive operational data and the design is based on the proven 130 t/h DP boiler.
The development of the UltraMulti is based on an identified client need for even higher productivity from biomass combustion from multiple fuel types; poor or variable quality fuels. The lower calorific value of such fuels means that even small efficiency gains can reap financial benefits that are significant enough to make a difference to ROI. The UltraMulti has been developed using fuel data from over 65 fuel types, and is optimized to suit a wide variety of fuels, as well as being able to handle fuels with moisture levels up to 60%.
As with all DP biomass boiler technology, the boiler design and materials are specifically targeted at reducing the corrosive effects and slagging propensities of common straw-based fuels.
