Biomass Co-Firing for Coal-Fired Boilers

Mutagenicity in emissions from coal- and oil-fired boilers.

The mutagenicity of emission samples from three oil-fired and four coal-fired boilers have been compared by using the Salmonella/microsome assay. Very little or no mutagenic activity was observed in samples from five of these boilers. The sample from one oil-fired boiler showed mutagenic activity of about 500 revertants/MJ, and the sample from a coal-fired fluidized bed combustor had an activit...

Control of mercury emissions from coal-fired electric utility boilers.

Introduction During combustion, the mercury (Hg) in coal is volatilized and converted to elemental mercury (Hg) vapor in the high temperature regions of coal-fired boilers. As the flue gas is cooled, a series of complex reactions begin to convert Hg to ionic mercury (Hg) compounds and/or Hg compounds (Hgp) that are in a solid-phase at flue gas cleaning temperatures or Hg that is adsorbed onto t...

Air and Fuel Staged Co-combustion of Coal with Biomass in Power Station Boilers

The overall objective of this investigation is to develop a technology to employ biomass as substitute fuel for coal to help reduce NOx.. It was achieved by governing NOx formation kinetics through in-furnace air and fuel staged co-combustion technology. An extensive series of experimentation was carried out in a 20 kW down fired combustor to evaluate the effect of co-firing of Shea meal, Cotto...

Advanced Technologies for the Control of Sulfur Dioxide Emissions from Coal-Fired Boilers

Executive Summary The Clean Coal Technology (CCT) Program is a government and industry cofunded effort to demonstrate a new generation of innovative coal utilization processes in a series of " showcase " facilities built across the country. These projects are carried out on a scale sufficiently large to demonstrate commercial worthiness and to generate data for design, construction, operation, ...
