The Electric Power Research Institute (EPRI) performed an extensive investigation on fire detection for coal pulverizer or mill systems. The studies showed that there is an emergence of low rank, high reactive coals as a base fuel for power plants which is resulting in an increase in pulverizer system

Pulverizer Fire and Explosions 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. Fundamental precautionary methods to reduce the chance of a pulverizer “puff” is to ensure the following:
a mill fire would pay for the system many times over. This unique detection system is specifically designed to detect rapid build-up of carbon monoxide inside pulverizing coal mills and silos.

Coal Fire Detection Systems Spontaneous Coal Combustion Potential coal fires and coal-induced explosions pose life-threatening safety issues and major economic concerns for any industry that uses pulverized coal in combustion systems. Coal that stagnates at normal operating temperatures in a coal supply or storage system has the
concerning pulverizer fuel system fires (this supplements informa-tion provided in PSB-10). The new recommendations include fire detection systems, actions to be taken when a fire occurs, inerting systems for various coal clas-sifications, and fire extinguishing procedures for air swept pulver-izer systems.

Detecting moving fires on coal conveyors. To comply with certain elements of the Clean Air Act Amendments of 1990, a number of utilities operating coal fired power plants have switched to low-rank
Fire Detection Methods For Coal Pulverizer Systems. 201821the risk of an explosion is low Vertical Spindle Mills The vertical spindle mill is a medium speed pulverizer and maintains a considerable amount of fuel in the mill system when operating Coal collects on the grinding table in the classifier in the pyrite collection sec tion below the
This invention relates to safety systems for coal pulverizers. Actual CO measurements are also used for fire detection in coal pulverizers since that CO buildup is related directly to the oxidation rate of coal. Infrared gas analyzers are used to compare the CO content of the incoming and outgoing mill air and in effect, the amount of CO

Fire protection for coal powered plants. Fire protection to pulverizers. Design shall be in accordance with NFPA 85. Use of carbon monoxide gas detection systems is strongly recommended as an early indication of conditions which could lead to fire initiation or even explosion.
Fire Detection Methods for Coal Pulverizer Systems MILL COAL FEED IR BURNERS CLASSIFIER Figure 5 Ball Mills Suggestions for Enhanced Fire Detection on Double Ended Ball Mills The ball mill is a slow speed mill and has two primary areas where coal pockets can exist and create fires: the inlet/ outlet ductwork and the classifier.
In order to deal with the increasing threat of fires and explosions, fire detection early warning systems are proving vital to plant integrity. What is behind the increase in fire risk The move to low sulphur coal (notably with PRB in the USA), plus the multi-fuel burning in some plants has greatly increased the fire
