摘要:
A carbonization apparatus for coal with wide particle size distribution, a carbonization apparatus unit, and a carbonization method based on the apparatus. The apparatus comprises a char discharge outlet (1), a combustion heating chamber (3), a coal feeding inlet (5), and a pyrolysis gas exhausting pipe (4). Wherein, two partition plates between which a pyrolysis gas channel (2) is formed are further provided in the carbonization apparatus, and orifices are provided on the partition plates to form a gas flow path from the fuel bed to the pyrolysis gas channel (2). Further, another internal having good heat transfer performance and made of a material resistant to high temperature, is provided in this coal carbonization apparatus to enhance the heat transfer from the heated wall of the apparatus to the fuel bed inside the apparatus. With the pyrolysis gas channel in the carbonization reaction apparatus, the gaseous products generated from coal pyrolysis are enabled to flow out timely. Through providing the internals, it greatly improves the effects of heat and mass transfer and reduces the secondary reactions to increase the tar yield and quality.
摘要:
A coke-oven door for a horizontal coking chamber has a metallic body with an inner surface covered by a thermally insulating layer and a metal plate mounted with the aid of vertically separated spacers on that inner surface. The plate consists essentially of a multiplicity of sections longitudinally adjoining or overlapping one another with limited mobility to facilitate relative thermal expansion. Each spacer comprises a first member secured to the door body and a second member coupled with an associated plate section, or with two such sections in their region of overlap, these members being interconnected with mutual play and/or with relative adjustability.
摘要:
A carbonization apparatus for coal with wide particle size distribution, a carbonization apparatus unit, and a carbonization method using the apparatus. The apparatus includes a char discharge outlet, a combustion heating chamber, a coal feeding inlet, a pyrolysis gas exhausting pipe, and two partition plates between which a pyrolysis gas channel is formed. Orifices are provided on the partition plates to form a gas flow path from the fuel bed to the pyrolysis gas channel. The pyrolysis gas channel in the carbonization apparatus permits the gaseous products generated from coal pyrolysis to flow out in a timely manner.
