Reactivity of limestone with coal in calcination process The samples of limestone were tested in mentioned laboratory apparatus using dry simulated flue gas at the temperature range 750-950°C in stationary bed. Results showed the temperature optimum of 850 °C. Results of this experiment substantially differ from desulfurization
Effects of the Limestone Particle Size on the …
Limestone particle size has a crucial influence on SO 2 capture efficiency, however there are few studies on the sulfation reactivity, which covers a broad range of particle sizes at low SO 2 concentrations. In this paper, a large-capacity thermogravimetric analyzer (LC-TGA) was developed to obtain the sulfur removal reaction rate under a wide range of particle sizes (3 μm–600 μm) and SO 2 ...
