Изобретение относитс к способу обжига зернистых материалов, например известн ка, в шахтной печи кин щего сло .The invention relates to a method of firing granular materials, for example limestone, in a kiln-type shaft furnace.
Известен способ обжига зернистого материала в шахтной печи кип ш,его сло , заключающийс в иодаче воздуха под решетку ири боковом вводе жидкого топлива.There is a known method of burning a granular material in a shaft furnace of the shaft, its layer, which consists in air iodation under the grate and side entry of liquid fuel.
Однако ири таком способе низка степень выгораии тоилива вследствие низкой интенсивности направленной циркул ции зернистого материала.However, this method has a low burnout rate due to the low intensity of the directional circulation of the granular material.
Целью изобретени вл етс устранение указанного недостатка.The aim of the invention is to eliminate this drawback.
Дл этого но нериферии решетки подают на 15 - 35% больше воздуха, чем в ее цеитра .1ьной части.For this, however, the neriperities of the lattice serve by 15–35% more air than in its zeitra .1 of the air.
На фиг. 1 изображена печь в разрезе; на фиг. 2 - разрез по А - А на . 1.FIG. 1 shows a sectional oven; in fig. 2 - section along A - A on. one.
Печь содержит зону подогрева 1 зерннстого материала. Подогретый в зоне воздух но воздуховодам 2, имеюш,им регулирующие 3 и измерительные устройства, ноступают в зону обжига 4, куда форсунками 5 вводитс жидкое топливо.The furnace contains a heating zone of 1 granular material. The air heated in the zone but to the air ducts 2, having regulating them 3 and measuring devices, enter the burning zone 4 where liquid fuel is introduced by nozzles 5.
Па воздуховоды 2, расположеииые в зоне 6 по периферии решетки, ири иомощи регулируюпи1х устройств 3 иодают воздуха на 15-35% больше, чем иа остальные.Air ducts 2, located in zone 6 around the periphery of the grille, and with the help of adjustable devices 3, iodine air is 15-35% more than the rest.
При этом образуетс устойчива направленна циркул ци частиц зернистого материала в направлении от стенки иечи к ее центру.A stable directional circulation of particles of granular material in the direction from the wall of the cylinder to its center is formed.
Предмет изобретени Subject invention
Способ обжига зернистого материала, преимуществеиио извести ка, в шахтной печп кии н1его сло , путем подачи воздуха под решетку и бокового ввода жидкого топлива, отличающпйс .ч тем, что, с целью повьпиени степени выгорани топлива в кип щем слое, по периферип penieTKii иодают на 15-35% больше воздуха, чем в ее центральной части.The method of burning a granular material, predominantly lime, in the mine furnace of the first layer, by supplying air under the grid and lateral input of liquid fuel, differs in that, in order to control the degree of fuel burnout in the fluidized bed, the periphery of penieTKii iodoes 15-35% more air than in its central part.
