摘要

The effects of the temperature-time history during coal devolitization and oxidation on the physical properties and the reactivity of resulting char were studied experimentally for temperatures and residence times typical of pulverized combustion. Experiments were also carried out at somewhat lower temperatures and correspondingly longer residence times. An electrically heated laminar flow reactor was used to generate char and measure the rates of oxidation at gas temperatures about 1600K. Partially oxidized chars were extracted and characterized by gas adsorption and mercury porosimetry, optical and scanning electron microscopy, and oxidation in a thermogravimetric analysis system (TGA). A different series of experiments was conducted using a quadrople electrodynamic balance. Single particles were suspended electrodynamically and heated by an infrared laser in an inert or oxygen-containing atmosphere. During the laser heating, measurements were taken of particle mass, size/shape, and temperature.

Colombia set for record coal productionColombia will report a record level of coal production thisyear, driven by a ramp up in thermal coal output from the secondquarter of the year, as producers extended their exportreach beyond traditional Atlantic markets. Analysts expect Colombia to produce around 90mn metrictonnes of thermal coal in 2016, up from the official 80.7mn tshipped last year. Estimates range from 86.5mnt to 93.9mn t. [J] .
