Coupled heat transfer model for the combustion and steam characteristics of coal-fired boilers

Demonstration of Advanced Wall-fired Combustion Techniques for the Reduction of Nitrogen Oxide (no,) Emissions from Coal-fired Boilers

This demonstration project was intended to repower an existing plant facility, the Lakeside Station in Springfield, Illinois. A single Integrated Gasification Combined Cycle (IGCC) process train was planned to generate a net output of 60 megawatts. The plant consists of a combined cycle (gas turbine, heat recovery steam generator, steam turbine) power train located in the existing buildings and...

Characterization and Prediction of Oxy-combustion Impacts in Existing Coal-fired Boilers

Future use of coal for power generation in the US depends on technologies being made available to capture and store CO2 emissions from power plants. A key candidate CO2 capture technology is oxy-firing of coal. Application of oxy-firing to existing power plants presents unquantified challenges as the characteristics of oxy-firing compared to airfiring have not been fully determined. This presen...

Optimisation of combustion efficiency and emissions in coal-fired boilers using Computational Fluid Dynamics

As more power generation facilities fall under increasingly strict environmental regulations, many difficult emissions control questions must be answered. In addition, the changes on the electricity market make efficient generation vital if a plant is to remain viable. Until recently an effective method for identifying optimal emissions control technologies has been elusive. Fortunately, emissi...

INNOVATIVE CLEAN COAL TECHNOLOGY OCCn 180 MW DEMONSTRATION OF ADVANCED TANGENTIALLY-FIRED COMBUSTION TECHNIQUES FOR THE REDUCTION OF NITROGEN OXIDE (NOx) EMISSIONS FROM 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...
