Clean EnergyIntroductionIn recent years, increasing attention has been paid to the development and use of renewable energy sources, also known as clean energy. Many of these energy sources focus on generating electricity while reducing or eliminating the use of fossil fuels and greenhouse gases, and pollutants that they produce. Another related area of interest is the …

The Clean Air Act Amendments originally called for this rule to be completed more than a decade ago, with estimated health savings of $59 to $140 billion that will be reached in 2016 when the rule is fully implemented. Despite these advances, the Clean Air Act is under threat from both the legislative and executive branches of the government.

Consider a burner with a flow of coal and primary/transport air. Oxygen for combustion is in deficit, the excess air factor being less than 0·5. Introducing a plasma source heats the coal/air mixture to the temperature that brings about complete devolatilisation and induces partial gasification of the char carbon, producing a highly reactive ...

Coal is ground in a rod mill slurried with water, and gasified in a pressurized, two-stage (slagging first stage and non-slagging entrained-flow second stage), oxygen-blown, gasifier. The product gas is cooled through heat exchangers and passed through a conventional cold gas cleanup system which removes particulates, ammonia, and sulfur.

The Clean Air Act, especially after amendments passed in 1990, drove a shift toward low-sulfur coal as one of the main methods of reducing sulfur dioxide emissions from coal plants. Since the predominantly subbituminous coal west of the Mississippi emits much less sulfur per unit of energy, this trend favored western surface mines as a dominant ...

Coal and air feed to the pulverizer is controlled by one of two methods: 1) proportioning the coal feed to the load demand and adjusting the primary- air supply to the rate of coal feed, or 2) proportioning the primary air through the pulverizer to the load demand and adjusting the coal feed to the rate of air flow.

The Mill Control is a set of logic that regulates each pulverizer on the unit and sets the amount of coal fed to the mill, the amount of primary air flowing through the mill, and the temperature of the coal/air mixture leaving the mill. The mill control strategy is dependent upon the type of mill being used on a particular unit.
