Biomass: rice hulls waste-to-energy
Biomass: rice hulls waste-to-energy
(OP)
About biomass fueled power plants: using rice hulls to fuel power plants was not very succesful in the late 1980s. Problems: high emissions (PM,NOx, boiler slagging, fuel logistics. Does anyone know about possible new technical develpments resulting in a more promising future for the application of rice hulls waste-to-energy? Many thanks for your help in advance!

Sadly, this is the case with many engineered products and systems, which are applied rather than designed. This leads to their misuse, unsatisfactory performance, and in a too many cases, an unjustified condemnation of the whole idea.
KMW did work in the area of rice to energy in the late 80's, but I do not know how it turned out. They installed a burner/boiler system at ORTECH in the 80's which was used to test a variety of solid fuels (pine cones, tire chips, high sulfur coal, etc.) with what I recall were acceptable emission levels.
I have not been involved in this area for over ten years, so my ideas may be outdated, but I suggest you give them a call before you discard the whole idea.

On of the 'new' technologies that allows biomass to be combusted more easily is fluidised bed reactors. Because they allow more air circulation between the particles, and have a built in thermal fly-wheel circulating with the particles inside the combustion chamber, they tend to be a far more efficient way to combust low-quality fuel (like rice husks.) Insofar as I know, many companies are having success with this approach. Co-firing with a higher-quality fuel is another approach that would make this viable.
Do a search for "fluidised bed reactors" to find out more.
