Pulverized Coal Pipe Testing and Balancing. Pulverized Coal Pipe Testing and Balancing By Richard F (Dick) Storm, PE The first step in optimizing combustion system performance is balancing the air and fuel flowing through each of the plant's coal pipes—the pipes that convey the air/fuel mix from the pulverizers to the individual burners in the furnace wall Also necessary is information on ...

Just how dirty is a coal-fired power plant? The answer, it turns out, can change a lot from hour to hour. The pollution that forms downwind of a power plant depends on shifting factors in the air.

The first-of-its-kind lawsuit demands that the EPA abide by Section 111 of the Clean Air Act, which requires the EPA to review air pollution standards for paper mills every eight years, according to Vera Pardee, Senior Attorney with the Climate Law Institute. The last time the EPA reviewed paper mill standards was in 1986—twenty six years ago.
