Effects of pyrite on the spontaneous combustion of coal ...

Sep 28, 2015 · Pyrite has a significant effect on the spontaneous combustion of coal. The presence of pyrite can change the propensity of coal towards spontaneous combustion. The influences of various pyrite contents on the parameters of spontaneous combustion, such as index gases, temperature and released heat etc., were investigated in this study.

from coal-fired plants can be controlled pre-combustion, in-combustion and post-combustion. Pre-combustion control is by coal selection and coal preparation. In-combustion control is by optimising combustion and the injection of sorbents into the flame zone. There are various methods of post-combustion control of PM 2.5
