As limits on SO 2 emissions become tighter, many coal-fired utility power plants are adding new flue gas desulfurization (FGD) systems or upgrading existing ones. The majority of these systems employ ...

Limestone slurry needs to move efficiently through a complex process, meaning that selecting the right pumps and valves is critical. As new coal-fired power plants come on line to meet rising demand ...

In the flue gas scrubbing process, water evaporates from the scrubbing fluid as the flue gas is cooled to the adiabatic saturation temperature. Under equilibrium conditions, water must be added to the ...

Recovering heat and water from flue gas can reduce water usage and boost power plant performance. The National Energy Technology Laboratory has tested a promising technology that condenses water and ...

Many years ago, someone — I honestly have forgotten who — told me: “Thermodynamics isn’t just a good idea, it’s the law.” Anytime you conjure up a new idea about how a heating or cooling system might ...
