Coal Pulverizers PTC 1969. This standard is being maintained under Stabilized Maintenance. Stabilized maintenance is an option for maintenance of a standard that requires status review every 10 years rather than revision or reaffirmation every 5 years. The Standards Committee shall consider all requests and recommendations for change ...
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.
Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner.
Pulverized Coal Firing Systems. Slag caused by poor burner setup and pulverizer performance issues can be seen forming inside the furnace. Pulverized coal [PC] firing can pose unique challenges such as poor grinding performance, high carbon in ash, slagging problems and excessively high furnace heat fluxes due to combustion related issues.

ASME PTC : Coal Pulverizers. ASME PTC, 69th Edition, 2021 Coal Pulverizers OBJECT AND SCOPE This Code appIies to the pulverizing system as a whole, including all the component parts necessary to take the raw coal, hot air and tempering air at the system inlet, and deliver pulverized coal in proper mixture with air and/or flue gas at the desired temperature at the outlet of the system.
Typical maintenance costs and intervals for each pulverizer gearbox were as follows: Oil changes required every 12 months at a cost of 5,000 in material and labor and 20,000 to 50,000 in lost electrical production, typical of most coalfired power generation units of this timeframe. This particular plant had 13 of these coal pulverizers ...
