Characteristics of the active lime: test method for the degree of activity. Take 50g sample with water and mix into a saturated solution after adding phenolphthalein powder pink plant desulfurization offer, then the concentration of 4N (mol) HCl (hydrochloric acid) high-power plant at an ambient temperature of 40 ℃ ± 1 ℃ desulfurization powder, continuous 10min (minutes) titration, and after thorough dropped milliliters (titration value) is the "active degree" value of HCl. Amount of hydrochloric acid was dissolved, the higher the activity of the power plant desulfurization powder, the better the quality of lime. The main factors affecting the quality of the lime burning: limestone quality and particle size. CaO content and crystal structure of limestone is burned out of the premise of good quality lime, and limestone particle size ratio is reasonable (Large / Small = 2/1), to improve the state of the furnace air movement, heating the material to enhance the effect of decomposition.
