Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will

A coal-fired thermal power station is a power plant in which the prime mover is steam driven. Water is heated, turns into steam, and spins a steam turbine, which drives an electrical generator, as schematically shown in Fig. 1.9.After it passes through the turbine (one to three stage), the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle.

For nearly 100 years—ever since pulverized coal combustion was adapted for power generation—GE has been a leader in coal mill technology for the power industry. That leadership continues today with the world's largest fleet of installed power milling equipment.
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 grinding table, and at the fan exit for exhauster systems. These are the prime locations of fires.
Reliable coal pulverizer performance is essential for sustained full-load operation of today's power plants. An effective pulverizer must be capable of handling a wide variety of coals and accommodating load swings in utility boilers as large as 1,300 MW.. B&W's pulverizers, found at power stations throughout the world.

raw coal top size, 7% moisture and produces pulverized coal that is 70% passing 200 mesh fineness (red line). This is pretty standard. Now, take that same pulverizer and provide fuel that is 40 HGI, still ¾" top size and still 7% moisture, but increase the fineness requirement to 80% passing a 200 mesh sieve.

No coal, no fire. No fire, no steam. No steam, no electricity. At this utility each of the two generating units employ six pulverizers, each on a continuous basis. Each mill pulverizer is responsible for about 130 megawatts of power. When the coal quality is good, the unit can run at full capacity on five pulverizers.
Operating data from a coal mill is used to compare the fault detection observer-based method and PCA/PLS models based approach. There are 13 process measurements available representing different temperature, mass flows, pressures, speed etc in the coal mill. The measurement is not updated, if the variation is less than 1%.
