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 Problem Coal fired power plants typically operate several ball mills or coal pulverizing mills to crush the incoming coal to the optimum size for combustion. This means that each. Chat with sales. trobleshooting of coal crusher ... Ring Granulator Type Coal Crusher Working .
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.
Reliable coal pulverizer performance is essential for sustained fullload 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.. BW''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.
Optimized coal pulverizer performance is a prerequisite for ensuring the best furnace combustion efficacy. Here are some solutions for overcoming commonly identified combustion problems.
