OBJECTIVES Coal Fired Power Plant Operations

When coal fired plant operates then the heat transfer surfaces gradually become fouled and plants are fitted with soot blowers that are used periodically to clean the surfaces. If the sootblowers are used too much then operating costs will increase due to the steam requirement of the sootblowers. Maintenance costs .

Lessons Learned from Existing Biomass Power Plants

The cost of biomass fuel from mill wastes and urban wood wastes can range from about $0/MBtu to about $1.40/MBtu, depending on the distance from the fuel source to the power plant. Getting to zero fuel cost depends on locating a power plant in an urban area next to a wood waste processor, or next to a large sawmill or group of sawmills.
