MERCURY CONTROL ALTERNATIVES FOR COAL-FIRED

EPA has formulated a goal to reduce mercury emissions from coal-fired power plants 50 to 70% by 2005 and 90% by 2010. Senator Jeffords has proposed a 90% reduction in Hg emissions by 2007. President Bush's Clear Skies proposal has two steps in Hg reduction, 45% by 2008 and 67% by 2018.

AG Healey Calls on EPA to Withdraw Proposal That Weakens

The Administration's proposal to repeal and replace the Clean Power Plan would allow dirty and aging coal-fired power plants to extend their lives by making upgrades without having to install pollution controls, and would result in up to 61 million more tons of carbon dioxide emissions.

EPA's Boiler MACT: Controlling Emissions of Hazardous Air

Thus, there is widespread interest in the proposed rule's requirements and their potential effects. EPA proposed the regulations because it has found, based on emissions data, that boilers (including coal-fired and biomass-fired boilers) are major sources of hazardous air pollutants (HAPs).

Fossil fuel power station - Wikipedia

Fossil fuel power station. The flue gas from combustion of the fossil fuels is discharged to the air. This gas contains carbon dioxide and water vapor, as well as other substances such as nitrogen oxides (NO x ), sulfur oxides (SO x ), mercury, traces of other metals, and, for coal-fired plants, fly ash.

How to Run a Coal Fired Boiler at the Best Efficiency

Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.

Reducing Emissions from Coal Plants

Reducing Emissions from Coal Plants There are three ways to reduce the CO 2 emissions from a coal plant: 1. Fuel switching - replacing part or all of the fuel with a lower carbon fuel like biomass or natural gas (fuel switching) 2. Efficiency improvement - increasing the efficiency of the plant so less CO 2 is emitted to produce the same output 3.
