摘要:本发明涉及一种用于有机物或有机物混合物的热解和气化的方法。把有机物引入到干燥和热解反应器(1)中,所述有机物在其中与燃烧流化床(3)的流化床材料(35)接触,或者所述有机物在其中与流化床材料(35)和燃烧流化床(3)的反应器壁接触,从而进行干燥和热解。使所述固体含碳残渣,任选的是带有部分蒸汽和部分热解气体,以及所述流化床材料返回到燃烧流化床(3)中,所述有机物的含碳残渣在其中燃烧,所述流化床材料被加热并重新引入到热解反应器(1)中。来自干燥的蒸汽和热解气体(13)随后在另一个反应区域(2)中用可冷凝物质处理,因此,可以获得具有高热值的产物气体(23)。在至少一个或多个热解反应器(1)中进行所述干燥和热解。所述热解残渣在其中燃烧的燃烧流化床(3)以静态流化床的方式操作。把热解气体(13)引入到间接热交换器中。使燃烧废气(37),任选的是与燃烧流化床(3)的流化床材料一起与间接热交换器(2)接触,使得它们的热含量用于热解气体(13)与冷凝剂(21)的反应。

Abstract: An apparatus for pyrolysis and gasification of organic substances and mixtures thereof is provided with a pyrolysis reactor ( 1 ), a fluidized-bed firing ( 3 ) for pyrolysis residue, a reaction zone ( 2 ) for the pyrolysis gases ( 13 ) and circulating fluidized-bed material ( 35 ). The pyrolysis reactor ( 1 ) has a sluice for introducing application material ( 10 ) thereinto. An inlet for the fluidized-bed material ( 35 ) is disposed next to the combustion fluidized bed ( 3 ). Transport apparatus ( 14 ) for mixture of solid pyrolysis residue and circulating fluidized bed material ( 35 ) is disposed at or near a bottom of the fluidized bed ( 3 ) and lower end of the pyrolysis reactor ( 1 ). An overflow is situated at or near the top of the fluidized bed ( 3 ) while a heat transfer member is positioned within the reaction zone ( 2 ).
