SECTION 5 Methods of sampling and analysis

International methods of sampling should be used to ensure that valid sampling procedures are applied when feed is being tested for compliance to a particular standard or objective. The Codex General Guidelines on Sampling – CAC/GL 50-2004 (FAO/WHO, 2004) provides information to facili-tate the implementation of these goals (Box 21).

Pulverizer Fire and Explosions

Pulverizer housing or burner lines are glowing red. Mill fires require immediate attention to prevent damage to the pulverizer and more damaging mill “puffs”. Explosions in a pulverized coal system are normally called “puffs.”. A mill puff is an explosion in the mill system caused by an explosive combination of coal, air and temperature.
