PM2.5 and Mercury Emissions From a High Ratio Fabric Filter After a Pulverized Coal Fired Boiler

Large efforts are made to limit the emissions of fine particles and mercury from coal combustion. Modern fabric filters are certainly an alternative for an efficient removal of fine particles and offer also the option to inject adsorbents to improve the removal of mercury. In this study the particle size distribution was measured after a modern design high ratio fabric filter (HRFF) located aft...

Mining Temporal Data: A Coal-Fired Boiler Case Study

This paper presents an approach to control pluggage of a coal-fired boiler. The proposed approach involves statistics, data partitioning, parameter reduction, and data mining. The proposed approach was tested on a 750 MW commercial coal-fired boiler affected with a fouling problem that leads to boiler pluggage that causes unscheduled shutdowns. The rare-event detection approach presented in the...

Handling and Co-firing of Shredded Municipal Refuse and Coal in a Spreader-stoker Boiler*

A system for handling up to 120 tons/day of municipal refuse has been developed for co-firing with coal in a spreader-stoker boiler at the Colum­ bus, Ohio, Municipal Electric Plant. This system is unique in that the refuse has undergone only shred­ ding to 90 percent minus 4 in. (10 cm) and magnetic separation of ferrous material. The refuse-handling system comprises: (1) a push-pit with a hyd...

Increasing the Efficiency of Existing Coal-Fired Power Plants

Coal has long been the major fossil fuel used to produce electricity. However, coal-fired electric power plants are one of the largest sources of air pollution in the United States, with greenhouse gas (GHG) emissions from burning of fossil fuels believed to be the major contributor to global climate change. Regulations under development at the Environmental Protection Agency (EPA) would impose...
