Using gasifier in direct heat rotary dryer

A non-ordinary type of solid fuel gasification reactor, which was under development for the few past decades and it is briefly described as indirect heat rotary kiln gasifier, seems to be capable

    An integrated system model was developed in UniSim Design for a dual fluidized bed (DFB) biomass gasifier and a rotary biomass dryer using a combination of user-defined and built-in unit operations. A quasi-equilibrium model was used for modelling biomass steam gasification in the DFB gasifier. The biomass drying was simulated with consideration of mass and energy balances, heat transfer, and

    A gasifier system includes a reactor for receiving a wet feedstock which has a base and a container rotatably connected to the base such that a rotation of the container causes a mixing of the feedstock in an interior of the reactor. The interior is bounded by the base and the container. A space between the base and the container allows an entry of oxygen into the interior

    May 01, 2016 In many industrial processes, rotary dryers are relied upon for high capacity, consistent drying of bulk solids — and for good reason. They offer innumerable benefits, both to the process and the product. One of the most prominent components of a rotary dryer is a large, rotating cylinder called the drum shell. Drying air or process gas flows through the drum in co-current or counter-current
