Coastal power stations, due to their proximity to major urban areas, tend to be better managed in terms of production consistency and environmental standards. In China and India in particular, coastal power stations tend to mill coal more finely, use superior emissions to control technologies, and have a tendency to use higher-quality coal blends.
Boilers for steam generation in power plants and process industries use coal as fuel. The percentage of boilers operating with coal as fuel outnumbers the boilers using all other fuels combined. Coal is pulverized before firing for achieving a stable and efficient combustion. Many types of pulverizers are used in boilers by different designers.

Power Engineering June 2013
The most popular type of coal-fired power station is a pulverized coal station that use coal ground to a powder using mills as fuel. The powdered coal is burnt in a boiler built from walls containing water tubes to collect the heat produced while other water tubes collect the heat in the flue gases exiting the boiler.

And there are now 78 countries using coal power, up from 66 in 2000. Another 16 plan to join the club, notably Egypt and the United Arab Emirates. CO2 emissions from existing plants are enough to breach the carbon budget for 1.5 or 2C. These limits would mean no new coal plants and closing 20% of the fleet early, according to one recent study.

Duke Energy has been using coal to produce electricity in the Carolinas since 1911. Those first coal-fired plants (in Greensboro, N.C., and Greenville, S.C.) only supplemented the company's use of hydroelectricity. In the 1920s, the growing demand for electricity began to outstrip the availability of hydroelectric generation.
Jun 30, 2014 · The retirement of coal plants could actually provide further opportunities for CHP at paper and pulp mills however, Scharff and Petersen noted. They envision utilities launching new power plants, potentially biomass or gas plants, located next to mills that could turn the resulting heat into thermal and extra electric power.
INTRODUCTION Efficient operation and control of coal pulverizing mills in power stations is one of the major factors in power plant performance. In spite of improved mechanical design mill operations continue to present the plant operator with more problems than perhaps any other single set of plant auxiliary equipment.
Texas power plants released nearly 257 million tons of CO2, as much as the next two states - Florida and Ohio - combined, and more than seven times the total CO2 emissions from power plants in California. Texas opened three new coal plants toward the end of 2010, with a combined capacity of 2,156 megawatts.
