Traveling grate stoker Grate surface is made up of Cast Iron bars joined together by links to form endless belt. Belt wound around two sprockets. A coal gate regulates the depth of fuel bed. Simultaneous adjustment of Fuel bed thickness primary air flow controls the burning rate so that at the end of its rear ash only remains.

Introduction To Boiler

Stokers are classified according to the method of feeding fuel to the furnace and by the type of grate. The main classifications are spreader stoker and chain-gate or traveling-gate stoker Spreader Stokers Spreader stokers utilize a combination of suspension burning and grate burning. The coal is continually fed into the furnace

Dec 15 2015 A spreader stoker burning process is currently used on Reunion Island. Optimized for the combustion of biomass and co-combustion with fossil fuels it burns bagasse during the sugarcane harvest and coal the rest of the season. Coal fly ashes resulting from this specific combustion system referred as Spreader Stoker Coal Fly Ashes SSCFA are currently sent to landfill.

Guide To Clean And Efficient Operation Of Coalstoker

-------f SPREADER STOKERS In a spreader stoker coal is spread evenly over the entire grate surface by mechanical feeders located at the stoker front above the grate. Because the coal is thrown onto the grate there is some suspension burning of the coal fines.
