The REMASCO system incorporates three stages of combustion. The first stage takes place in the primary "gasification" chamber and the second stage is within the intermediate mixing chamber. The third stage is the final excess air combustion process, which takes place in what is most commonly referred to as the "secondary" combustion chamber (despite the secondary chamber being the third stage of combustion).
The REMASCO gasification system is based on a simple and proprietary cellular rotating chain grate design that contains few moving parts. It maximizes operational flexibility by uniformly and gently managing the fuel bed.
A significant advantage of the REMASCO gasifier design is that it allows combustion to be precisely controlled and monitored over a wide range of oxygen concentrations in the under-fire combustion air, from less than 5% oxygen to greater than 15% oxygen. This control flexibility allows fuels with different combustion characteristics and ash properties to be treated equally effectively, from near pyrolysis through all degrees of gasification through to single stage excess air combustion. This characteristic is what allows the REMASCO technology to be used for Enerpax pellets, wood pellets, wood chips or even particularly difficult biomass materials with problematic low melting-point ash constituents.
