All moving parts are protected from the high furnace heat. No mechanical stress is imposed on the grate surface, only the weight of the fuel is carried. DB Riley Traveling Grate units combine the simplicity of design and robust construction which are characteristic of DB Riley fuel burning components with a modular concept which permits the entire grate to be shipped in shop assembled units. The savings in erection labor which result, and the advantages of shop assembly assure superior performance at a lower installed cost. U nit incorporates separate power and mechanical drive units.
Separate units permit flexibility in positioning for ease of installation and maintenance.
The mechanical drive unit is directly connected to the grate drive, eliminating the need for variable speed drives with gears and sprockets. The drive is a heavy duty design, capable of running in reverse to facilitate maintenance or relieve a grate jam. Power consumption is low. Operation is smooth and quiet. Hydraulic Drive Unit DB Riley also provides a stationary W ater C ooled G rate which is suitable for burning cellulose fuels including wood.
