    摘要： An inclined hearth combustor which generally includes a primary combustion chamber having a plurality of stepped hearths, a secondary combustion chamber in communication with the primary combustion chamber and a boiler having an inlet in communication with the secondary combustion chamber. The secondary combustion chamber includes a refractory-lined cyclone separator for removing fly ash from combustion gases exiting the primary combustion chamber and the boiler inlet is surrounded by the cyclone separator. The primary combustion chamber may further include an ash transfer ram movably disposed between two stepped hearths, wherein the ash transfer ram includes a top layer of refractory material extending rearwardly from a leading edge thereof. The ash transfer ram may further include a plurality of V-shaped wheels attached to a bottom surface thereof, a replaceable wear plate disposed on a side surface thereof and/or a wiper blade fixed on a forward face thereof. At least one hearth may include two spaced rows of air feed-tubes longitudinally embedded therein for delivering a combustion gas into the combustion chamber. The air-feed tubes may intersect with an air distribution plenum for simultaneously delivering the combustion gas to the air feed-tubes. The primary combustion chamber may further include a reciprocating loader ram movably disposed on the top surface of the top-most hearth for pushing combustible material on the top-most hearth, wherein the loader ram has a bottom surface and at least one longitudinally extending replaceable wear strip disposed thereon.
