The finer the grinding of coal, the more efficient its combustion. The difference is that the highenergy ignition devices which generate sparks replace people's hands. The heart of a pulverized coalfired boiler is the pulverizer, also known as the mill • Use: Pulverized coal can be used as a reducing agent by injecting it through the tuyeres.

burning gas or coal. In a nuclear plant, the heat is generated by the fi ssion of some of the uranium in the nuclear fuel assemblies. When the nucleus of an atom of, for example, 235U absorbs a neutron, it may split (or fi ssion) into two pieces, giving off energy as heat and a few more neutrons to continue this nuclear chain reaction.
