초록 ▼

A process which comprises the steps of introducing combustible solid material into an upper section of a pyrolysis chamber, moving the material downwardly at a controlled rate through multiple stage zones in the pyrolysis chamber, passing hot gaseous products of the partial oxidation of carbon char upwardly countercurrent to the movement of the solid material in the pyrolysis chamber, driving off volatile matter in the solid material, depositing carbon char in the lower section of the pyrolysis chamber, introducing air into the lower section of the pyrolysis chamber and partially oxidizing the char to form the hot gaseous products, removing a hot overhead fuel gas, passing the overhead fuel gas to a combustion chamber for combustion thereof with air, and applying the resulting hot combustion gases exiting the combustion chamber to a heat load. Where the combusible solid material contains one or more acid components, the process also includes the step of passing the overhead fuel gas to a zone containing a chemical adsorbent. An apparatus for carrying out the above process comprises a pyrolysis chamber, a feed-lock system for introducing a combustible solid feed material into an upper section of the chamber, a series of spaced vertically disposed horizontally moveble grates in the chamber, an air inlet into the lower section of the pyrolysis chamber, ash removal apparatus in the bottom of the chamber, a combustion chamber for the overhead fuel gas, and a heat load to which the resulting hot combustion gas is applied.

A process for pyrolysis and combustion of combustible solid material which comprises: introducing combustible solid feed material containing volatile matter into an upper section of a pyrolysis chamber having a lower section and a bottom, moving said material downwardly at a controlled rate through multiple stage zones in said pyrolysis chamber, said multiple stage zones being provided by a series of spaced vertically disposed horizontally moveable grates in said pyrolysis chamber, depositing carbon char in the lower section of the pyrolysis chamber, introducing air into the lower section of said pyrolysis chamber and partially oxidizing said char to form hot gaseous products, passing said hot gaseous products of the partial oxidation of said carbon char upwardly countercurrent to the movement of said solid material in said pyrolysis chamber, and driving off said volatile matter in said solid material in a multistage equilibrium process, wherein substantial reaction equilibrium is achieved in each of said stage zones in the pyrolysis chamber between the solid combustible feed material and said upwardly passing hot gaseous products, removing ash and other non-combustible material from the bottom of said chamber, removing a hot overhead fuel gas comprised of said volatile matter from the solid material and the hot gaseous products of the partial oxidation of the carbon char, passing said overhead fuel gas to a combustion chamber for combustion thereof with air, subjecting said overhead fuel gas to combustion in said combustion chamber, and applying the resulting hot combustion gases exiting the combustion chamber to a heat load.
