Research Interests
I am interested in thermal processes involving biomass. Torrefaction, pyrolysis, gasification and combustion. I was responsible for developing a new generation of dimensioning programs for steam generator thermal design. I work on fluidized bed and recovery boilers. In addition to thermal design of CFB, I am involved with fouling and corrosion of biomass boilers such as Kraft recovery. Other main interests have been delivery, air distribution and combustion.
I have been involved with majority of recent worldwide purchases of biomass boilers for pulp and paper industry. Especially their environmental performance and emissions are of better focus.
I have lectured on boilers in technical conferences at all major continents and am interested in publishing also for educational purposes.
