Изобретение относитс  к области сжигани  топлива и может быть использовано на тепловых электростанци х.The invention relates to the field of fuel combustion and can be used in thermal power plants.

Целью изобретени   вл етс  повышение экономичности и снижени  недожога топлива .The aim of the invention is to increase the economy and reduce the underburning of fuel.

На чертеже изображена система подготовки углемасл ного гранул та к сжиганию в топке.The drawing shows a system for preparing coal-oil granules for combustion in a furnace.

Система содержит гранул тор 1, механический обезвоживатель 2, например сито, и камеру 3 растворени .The system comprises a granulator 1, a mechanical dehydrator 2, for example a sieve, and a dissolving chamber 3.

Способ подготовки углемасл ного гранул та к сжиганию в топке осуществл ют следующим образом.The method of preparing coal-oil granulate for burning in a furnace is carried out as follows.

Гидросмесь гранул та, приготовленного в гранул торе 1, поступает в обезвоживатель 2. Здесь происходит отделение гранул от воды, содержащей в виде тонких взвешенных фракций отходы гранул ции. Гранул т направл етс  в камеру 3 растворени  гранул та. Дл  интенсификации растворени  углемасл ных гранул камера 3 может быть оборудована мешалкой или насосами рециркул ции смеси. В камере 3 происходит разрушение гранул, растворение апол рного св зующего вещества гранул в органическом растворителе и переход твердой угольной фазы гранул в жидкую фазу с образованием суспензии уголь - растворитель - св зующее, котора  направл етс  в топку на сжигание.The slurry of the granulate prepared in granulator 1 enters the dehydrator 2. Here the granules are separated from water containing waste granulation in the form of fine suspended fractions. The granulate is sent to the granulate dissolution chamber 3. In order to intensify the dissolution of the coal granules, chamber 3 can be equipped with a mixer or mixture recirculation pumps. In chamber 3, the granules are destroyed, the apolar binder of the granules is dissolved in an organic solvent, and the solid coal phase of the granules is transferred to the liquid phase to form a coal-solvent-binder suspension, which is sent to the furnace for combustion.

Пример. Уголь марки «Г с зольностью 20,7% и измельченный до крупности менее 0,2 мм смещивают с мазутом марки М100 с образованием углемасл ного гранул та. Содержание мазута в гранул те составл ет 25% к массе угл , крупность гранул - 0,5-2,5 мм, влажность после механического обезвоживани  - 24-26%. Гранул т подают в камеру растворени , куда в качестве органического растворени  ввод т подогретый до 100-180°С мазут марки МЮО. Общее количество мазута в смеси после растворени  гранул та составл ет 60% по весу.Example. Coal grade “G” with an ash content of 20.7% and crushed to a particle size of less than 0.2 mm is shifted with fuel oil grade M100 to form a coal-oil granulate. The content of fuel oil in the granulate is 25% by weight of coal, the grain size of the granules is 0.5-2.5 mm, and the moisture content after mechanical dewatering is 24-26%. The granulate is fed into the dissolution chamber, where, as the organic dissolution, MOOO brand oil heated to 100-180 ° C is introduced. The total amount of fuel oil in the mixture after the granulate is dissolved is 60% by weight.

При растворении гранул та одновременно идет процесс влаговыделени  воды (в виде пара), содержащейс  в гранул те. Влажность полученной в результате растворени  гранул та углемазутной суспензии составл ет 3% Така  суспензи  устойчива в течение 2-3 ч. Полученна  суспензи  подаетс  в топку.When the granulate is dissolved, at the same time, the process of water release (in the form of steam) contained in the granulate takes place. The moisture content of the resulting granulated coal-gas slurry is 3%. Such a suspension is stable for 2-3 hours. The resulting suspension is fed to the firebox.
