STUDY ON COMBUSTION KINETICS OF COAL POWDER
摘要
Abstract
In research of combustion of coal powder, the main techniques adopted in the measurement of combustion kinetic parameters consist of thermogravimetry, DTFS and pyro-test. In this study, a new unit for the test of gas-solid reaction was developed, in which coal powder can be steadily kept in suspension and reacted. Furthermore, this unit can better stimulate industrial fluidized bed reactor and detect the burnout of coal powder, combustion reaction rate and surface temperature of the particles. Thus, it much approaches to the real case.
Reactive kinetic tests of several coal-powders were studied with the new test unit in this paper. Based on test results and the mathematics model, the kinetic parameters, such as reaction rate, activation energy, constant in Arrhenius equation, were derived. Except for anthracite, soft coal was tested and researched. The test results will supply more reliable kinetic data for the design of industrial fluidized bed reactors.关键词
