Thermoanalytical study of drying kinetics of lignocellulosic fuels

Donskoy I.G., Kozlov A.N., Shamanskiy V.A. Thermoanalytical study of drying kinetics of lignocellulosic fuels // Journal of Physics: Conference Series. Vol.1261. No.1. ID: 012009. 2019. DOI: 10.1088/1742-6596/1261/1/012009 Lignocellulosic matter is usually hydrophilic, so its drying, in addition to the heat of the phase transition for water, also requires compensation of adsorption energy. In the present work experimental studies have been carried out to quantify the moisture adsorption energy,...

DEVELOPMENT OF MATHEMATICAL MODEL OF THE SYSTEM OF HIGH-TEMPERATURE CERAMIC HEAT EXCHANGERS OF PERIODIC ACTION

... plants, in which the processes of electric power generation are combined with the processes of coal gasification. Interest in this direction is explained by large natural reserves of coal and minimal harmful emissions into the atmosphere during the combustion of gas obtained during gasification. Asa rule, to improve the quality of gasification, air enrichment with oxygen is used, which is very expensive. An alternative way to increase the calorific value of the generator gas is to supply air heated ...

Numerical investigation of the staged gasification of wet wood

... disadvantages of conventional processes to be avoided. One of the previously proposed staged processes is investigated in this paper. For this purpose, mathematical models were developed for individual stages of the process, such as pyrolysis, pyrolysis gas combustion, and semicoke gasification. The effect of controlling parameters on the efficiency of fuel conversion into combustible gases is studied numerically using these models. For the controlling parameter are selected heat inputted into a 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...
