Microwave drying of a low-rank sub-bituminous coal DeepDyve

Jul 01, 2014Microwave drying of a low-rank sub-bituminous coal Some HRC's are cleaned, usually by wet techniques and these coals can have moisture levels between 12% and 25%. For a given set of conditions, the moisture content of the coal increases with decreasing particle size, because the larger surface area of the fine coal enhances its capacity to retain moisture.

DNR not imposing coal-ash rule on Columbia power plant

Bill Skalitzky, Alliant's manager of environmental services, said the company is in the "preliminary phases" of exploring dry-ash handling for Columbia. He said a dry-ash system will need to be in place by 2023, when Alliant must stop using the settling ponds to comply with a different set of federal rules.

Dry sorbent injection may serve as a key pollution control

Dry sorbent injection may serve as a key pollution control technology at power plants. Fabric filters are generally more effective (when combined with DSI) than ESPs, with respect to overall HCl reduction. For modeling purposes, EPA estimates a DSI system with a fabric filter is expected to achieve 90% removal of HCl, while an ESP only achieves 60% removal, although actual performance will vary by individual plant.
