Abstract

Представлены прямоточный газификатор с неподвижным слоем для получения генераторного газа из частиц сыпучей биомассы, способ эксплуатации такого прямоточного газификатора с неподвижным слоем, способ пуска такого прямоточного газификатора с неподвижным слоем и способ остановки такого прямоточного газификатора с неподвижным слоем. Благодаря тому, что подача воздуха производится через засыпку частиц биомассы в трубообразном элементе газификатора, обеспечивается равномерное распределение воздуха. Благодаря этому равномерному распределению в зоне окисления почти не имеет место разность температур. Результатом является то, что пиролизные газы, которые образуются над зоной окисления, равномерно протекают через зону окисления. Благодаря этой равномерности потоки газа и воздуха могут образовывать генераторный газ с незначительными количествами смол. Удерживание зоны окисления в стационарном положении достигается благодаря резкому изменению поперечного сечения между элементом газификатора и резервуаром газификатора у открытого конца вставного элемента газификатора, в результате которого получаются различные скорости течения. Благодаря расширению поперечного сечения, в отличие от традиционных газификаторов с неподвижным слоем, скорость течения снижается. Благодаря различным скоростям течения внутри и снаружи трубообразного элемента газификатора зона окисления в известной степени фиксируется перед открытым концом трубообразного элемента газификатора. Дополнительное преимущество расширения поперечного сечения состоит в том, что пиролизные газы при протекании через зону окисления не ограничиваются стенкой трубы. На стенках трубы не доминируют никакие равномерные условия обтекания и тем самым никакие равномерно высокие температуры. Если пиролизный газ протекает через зону окисления на краю стенки трубы, как это происходит в прототипе, длинноцепочечные углеводороды разлагаются не полностью. Вследствие того, что стенка трубы отсутствует, длинноцепочечные углеводородные соединения дополнительно разлагаются, что приводит к улучшению коэффициента полезного действия двигателя при использовании генераторного газа.A direct-flow fixed-bed gasifier for producing generator gas from loose biomass particles, a method of operating such a fixed-flow gasifier with a fixed bed, a method of starting such a direct-flow gasifier with a fixed bed and a method for stopping such a direct-flow gasifier with a fixed bed are presented. Due to the fact that the air is supplied through the filling of biomass particles in the tubular element of the gasifier, the air is evenly distributed. Due to this uniform distribution in the oxidation zone, there is almost no temperature difference. The result is that the pyrolysis gases that form above the oxidation zone flow evenly through the oxidation zone. Due to this uniformity, gas and air streams can form generating gas with insignificant amounts of tar. Holding the oxidation zone in a stationary position is achieved due to a sharp change in the cross section between the gasifier element and the gasifier tank at the open end of the gasifier insert element, which results in different flow rates. Due to the expansion of the cross section, in contrast to traditional fixed-bed gasifiers, the flow velocity decreases. Due to the different flow rates inside and outside the tubular element of the gasifier, the oxidation zone is to a certain extent fixed before the open end of the tubular element of the gasifier. An additional advantage of the expansion of the cross section is that the pyrolysis gases, when flowing through the oxidation zone, are not limited to the pipe wall. On the walls of the pipe no uniform flow conditions dominate, and thus no uniformly high temperatures. If the pyrolysis gas flows through the oxidation zone at the edge of the pipe wall, as is the case in the prototype, long-chain hydrocarbons do not completely decompose. Due to the fact that the pipe wall is missing, long-chain hydrocarbon compounds are further decomposed, which leads to an improvement in the efficiency of the engine when using generator gas.
