Description

при газификации многозолыюго топлива , в особенности с легкоплавкой золой, очень трудно избежать зашлаковани  генератора, что приводит к приостановке процесса. Дл  избежани  этого часто прибегают к плавлению шлака и удалению его в жидком виде, что достигаетс  повышением температуры в зоне горени . Такой метод работы неизбежно ведет к большим потер м тепла в виду скрытой теплоты плавлени  золы и тепла, тер емого при удалении гор чей золы. Кроме того большим недостатком разбираемого способа  вл етс  то, что такого вида топливо, как сланцевый полукокс, содержит недостаточное количество углерода, чтобы за счет его горени  и газификации получить нужное дл  плавлени  золы количество тепла. Чтобы достигнуть нужных температур, обычно добавл ют богатое углеродом топливо , например, металлургический кокс.When gasifying a multi-ash fuel, especially with low-melting ash, it is very difficult to avoid the slagging of the generator, which leads to a suspension of the process. To avoid this, slag is often resorted to and slag is removed in liquid form, which is achieved by increasing the temperature in the combustion zone. This method of operation inevitably leads to large heat losses in view of the latent heat of ash melting and the heat lost when hot ash is removed. In addition, a big disadvantage of the method being disassembled is that this type of fuel, such as shale semi-coke, does not contain enough carbon in order to get the amount of heat required for smelting the ash due to its combustion and gasification. Carbon-rich fuels, such as metallurgical coke, are usually added to achieve the desired temperatures.

Автором насто ш:его изобретени  предлагаетс  свободный от вышеуказанных недостатков способ газификации горючих в двойной вод ной газ. Способ этот состоит в том, что топливо , поступаюш,ее на газификацию,The author of the present: his invention proposes a method for the gasification of combustible into a double water gas, free from the above disadvantages. This method consists in the fact that the fuel supplied to it for gasification,

предварительно нагреваетс  в верхнечасти газогенератора до температуры ПоО - 120() потоком перегретого шпюльгаза. Газификаци  горючего проводитс  в средней части генератора , куда вводитс  тот же перегретый шпюльгаз вместе с вод ным паром . Кроме того, насто щий способ предусматривает использование физического тепла золы, дл  чего через зольную часть генератора пропускаетс  шпюльгаз, охладившийс  в верхней части генератора.It is preheated in the upper portion of the gas generator to a temperature of POC - 120 () with a stream of superheated gas. Gasification of fuel is carried out in the middle part of the generator, where the same superheated gas spool is introduced along with water vapor. In addition, the present method involves the use of physical heat from the ash, for which a spill gas is passed through the ash part of the generator, cooled in the upper part of the generator.

Предлагаемый способ может быть применен дл  сырого сланца, сланцевого полукокса, а также дл  других многозольных топлив, как, например, бурые угли и т. п.The proposed method can be applied to raw shale, shale semi-coke, as well as to other multi-ash fuels, such as brown coal, etc.

На чертеже представлена схема, иллюстрируюша  предлагаемый способ .The drawing shows a diagram illustrating the proposed method.

Генератор А состоит из трех зон: зоны нагрева и активации 7, зоны газификации 2 и зольной зоны 3- Нагретый шпюльгаз при температуре, соответствуюшей пределу разм гчени  золы (1170 - 1200°), подаетс  в первую зону генератора. Главна  часть потока направл етс  в верхнюю часть зоны нагрева и активации, где нагревает полукокс до температурыGenerator A consists of three zones: a heating and activation zone 7, a gasification zone 2 and an ash zone 3. A heated gas cell at a temperature corresponding to the ash softening limit (1170 - 1200 °) is fed to the first generator zone. The main part of the flow is directed to the upper part of the heating and activation zone, where it heats the semi-coke to the temperature
