THE mechanical handling of coal and ash at the modem power house is to-day a distinct and important problem. The design and layout of such plant, in order to comply with a particular set of local conditions, calls for a careful study of a number of different systems and types of plant. It is because this section of power-house work has become one in which so many different factors have to be considered that this book has been written. Its purpose is to collect in one volume the available data on coal and ash handling plant which concerns the power house and boiler house engineer in both large and small plants.

This section of the power house is more comprehensive than is generally assumed. In any complete coal handling plant, consideration must be given to the handling of the coal on delivery at the power house; and provision made for dealing with the whole of the products resulting from combustion. These latter include ash and clinker in the ash pit, also soot and dust on the heating surfaces, in the flues, and finally in the chimney. Each of these items are dealt with in turn, and their importance is readily realised when the daily consumptions of our super-power stations are considered.In view of the large quantities of ash and clinker to be transported from the modern power station.There would appear to be every reason for a closer consideration of clinker brick-making, as what is now dumped as a waste product may under suitable conditions be economically converted into a useful product. Like many engineering problems, the installation of the most suitable coal handling plant for a particular set of conditions is one of compromise. One installation will generally include a number of different systems and types of plant, and it is for the power station engineer to select the most suitable
