Modelling of porous biomass pyrolysis in screw reactor

Levin A.A., Kozlov A.N. Modelling of porous biomass pyrolysis in screw reactor // Journal of Physics: Conference Series. Vol.899. No.9. ID: 092008. 2017. DOI: 10.1088/1742-6596/899/9/092008 This paper is concerned with the development of a model of wood pyrolysis in a screw reactor as the first stage of the multistage gasification process. To prevent clinkering of particles and thermal inhomogeneities, screw-type transportation is used to transport fuel. In order to describe kinetics of pyrolysis...

Simultaneous velocity and temperature field measurement of high-temperature flows

Mikheev A., Zubtsov V. Simultaneous velocity and temperature field measurement of high-temperature flows // DLR-Mitteilung. 2001. P.377-381. The problem of temperature distribution detection using IR pyrometry in high temperature flows is addressed. Two-wavelength IR pyrometry being a direct and passive technique seems to be attractive method of obtaining 2D or even 3D temperature field as an expansion of conventional PIV or PTV. As opposed to conventional PIV and PTV the inherent blackbody radiation...
