Specialist Boiler

The DP Specialist boilers are customized products which are specifically designed to combust complex or difficult fuels.   The ‘high pressure high temperature’ boiler technology is manufactured with the most appropriate materials and supplementary systems to cater for the most difficult fuels.   Whether it is municipal waste or the lignin byproduct from 2G ethanol production, DP Specialist boilers are specifically designed to reach or even exceed the required performance levels from a chosen fuel, or from several, given fuel types.  

As with all DP’s boiler products, the starting point for optimizing the performance is a profound knowledge of the fuel characteristics.  Such characteristics will impact the design of the     Fuel feeding system; the combustion grate, furnace height and specific boiler parameters.  DP’s expertise in fuel analysis is a key aspect of our total solution approach.  

DP Specialist boilers can cater for more than one type of feedstock, or for different modes of the same biomass.   With every aspect of the DP Specialist Boilers expressly designed to get the most out of a particular fuel situation and to meet customer output requirements, the inherent challenges and problems can be addressed at the outset, and then minimized in the design.  This allows overall plant performance and efficiency to remain high, and reliably consistent.
