MaxSolo Boiler

The DP MaxSolo is a core product in DP Cleantech’s portfolio, consisting of a specialized, single-fuel ‘high pressure high temperature’ biomass boiler. Whether it is a ‘soft’ fuel such as wheat straw, or a ‘hard’ fuel such as wood, all components of the MaxSolo are specifically designed to maximize the performance from a chosen fuel.

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 feeding system; the combustion grate and the specific boiler parameters.  DP’s expertise in fuel analysis is a key aspect of our total solution approach.  

A boiler that is fine-tuned to cater to one fuel and its individual characteristics is even more important when dealing with varying fuel quality. With every aspect of the MaxSolo Boiler expressly designed to get the most out of a particular fuel, problems of fuel quality can be addressed at the outset, and then minimized in the design.  This allows overall plant performance and efficiency to remain exceptionally high, even when fuel quality cannot be guaranteed.
