Bottom ash is most commonly conveyed in a hydraulic system in which the ash is entrained in a high flow, circulating water system and delivered to either an ash pond or to a remote dewatering device. Alternatively, mechanical drag systems have been used to convey bottom ash to the dewatering storage bin because they use less water and usually have a lower initial cost.

The calorific value of coal varies considerably depending on the ash, moisture content and the type of coal while calorific value of fuel oils are much more consistent. The typical Gross Calorific Values of some of the commonly used liquid fuels are given below: 1. Fuels and Combustion Bureau of Energy Efficiency 2 Ch-01.qxd 2/23/2005 11:18 AM ...

A hydroelectric dam is one of the major components of a hydroelectric facility.A dam is a large, man-made structure built to contain some body of water.In addition to construction for the purpose of producing hydroelectric power, dams are created to control river flow and regulate flooding. In some rivers, small scale dams known as weirs are built to control and measure water flow.
