It represents the partial work of a project called "Mill Advisor" which investigated the common operational and maintenance problems of the coal pulverizer. Combining vibration monitoring and operational parameters such as flow rate, pressure drop and temperature ...
Two Case Studies The following two cases represent typical past experiences in pulverized coal–fired boiler testing results that illustrate the advantages of isokinetic coal sampling. Case Study 1: MPS-89 Pulverizer with Eight Coal Pipes. Fly ash loss on ignition (LOI) was in the
Case Study – Coal Pulverizer. August 2009 – A coal fired power plant on the east coast had a coal duct explosion that ripped through their fabric expansion joint and continued to burn when exposed to the atmosphere. The utility had replaced their 25 year old original hot air pulverizer metal expansion joints in favor of a less expensive ...

A large thermoelectric plant like this burns a lot of coal—in this case, about 11 million tons per year. Coal that has been ground into a fine powder by a pulverizer is blown into a furnace-like device, called a boiler, and burned. The heat produced converts water, which runs through a series of pipes in the boiler, to steam.
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.
Coal pulverizer downtime can be a major factor in reducing overall plant availability and reliability. ... Case Study. In March 2003, a major Canadian utility derated its Unit 4 due to a failure of the B mill. The mill was expected to be out of service for about a month. With lost production of approximately 864 MWh per day, the total estimated ...
• Coal Rejects – Less then 10 #'s per hour. • Pulverizer Power – With fuel changes to low HGI coals or operations with lower BTU coal (exceeding design capacity), mill motors are often undersized to achieve desirable performance. • Fuel Line Temperature of 165 - 175°F with low volatile coal …
The mathematical model and simulation of coal pulverizer has been presented in the paper using first principle mass and heat balance equations based on physical insight. The coal mass flow is modelled based on the mass balance model. The pulverized coal temperature is modelled by considering the coal and the pulverized coal as a lumped thermal mass.
