Изобретение относитс к технике сжигани высокообводнеиного твердого топлива.This invention relates to a technique for burning high water solid fuels.
По основному авт. св. № 163586 известен способ сжигани высокообводненного дробленого угл в топочных устройствах, при котором сжиганию подвергают водоугольную суспензию с размерами частиц до 200 мк.According to the main author. St. No. 163586, there is a known method of burning highly watered crushed coal in furnaces, in which a coal-coal slurry with a particle size of up to 200 microns is subjected to burning.
Однако на начальной стадии горени водоугольной суспензии интенсивное испарение влаги приводит к задержке воспламенени , которое происходит до образовани плотного сло твердых частиц (коркообразование) на поверхности капли.However, in the initial stage of burning the coal-water slurry, intense evaporation of moisture leads to a delay in ignition, which occurs before a dense layer of solid particles is formed (crusting) on the surface of the drop.
Целью изобретени вл етс интенсификаци процесса воспламенени . Достигаетс это тем, что в ноток водоугольной суспензии вместе с распыл ющим воздухом ввод т высокодисперсные добавки, например угольную пыль или минеральные вещества.The aim of the invention is to intensify the ignition process. This is achieved by introducing highly dispersed additives, for example, coal dust or mineral substances, into the notes of the coal-water slurry together with the spraying air.
Предложенный снособ осуществл етс следующим образом. Твердую примесь измельчают в мельнице (например, шаровой) до размера частиц О-100 мкм. Вместе с вентилирующим воздухом ее подают в воздуховод горелки (на любом рассто нии от последней).The proposed removal procedure is as follows. The solid impurity is crushed in a mill (for example, ball) to a particle size of about 100 microns. Together with the ventilating air, it is fed into the burner duct (at any distance from the latter).
На выходе из горелки воздущный поток, содержащий высокодисперсные добавки, смещиваетс с капл ми распылпваемой суспензии. В результате улавливани частиц примеси капл ми суспензии на их поверхности быстро образуетс корка. При обычном методе сжигани суспензии образование новерхностного сло (корки) определ етс только исходной рабочей влажностью топлива суспензии и тепловыми услови ми на начальном участке зоны горени .At the exit of the burner, the air stream containing the highly dispersed additives is displaced with drops of the sprayed suspension. By trapping impurity particles with droplets of a suspension, a crust quickly forms on their surface. In the conventional method of burning a slurry, the formation of the surface layer (crust) is determined only by the initial operating moisture of the slurry fuel and thermal conditions at the initial portion of the combustion zone.
