Abstract

FIELD: combustion of fuel. SUBSTANCE: device has vertical combustion chamber 1 with horizontal fire grate 2 and rotating plank 3 secured to a mechanism for displacement as a cantilever. The mechanism is constructed as transporter 4 which is provided with anchor chain 5 arranged along the side wall of combustion chamber 1 and enclosed in flat horizontal box 7 connected with an air source through a branch pipe provided with a gate. Continuous slot 11 is made in the walls of combustion chamber 1 in the zone adjacent to box 7. Box 13 with branch pipe 14, for supplying air and provided with gate 14, underlies grate 2. Fuel positioned on the grate 2 is blown by air supplied through box 13. Some of the fuel fractions are removed by air from the layer to combustion chamber 1. The remained pieces of fuel are burnt out and moved by plank 3. The fuel layer is displaced, and burning remainders fall into chute 12. Plank 3 is displaced with anchor chain 5. When a large piece enters between plank 3 and grate 2, plank 3 moves upward and back. Slots 11, which are made up as guides, and securing plank 3 to a link of anchor chain 5 to provide rotation of one link about chain 5 are used for this purpose. A portion of air is fed to box 7 through a branch pipe and then to combustion chamber 1 through slot 11. The air flow rate is controlled by the gate to prevent entry of fuel particle to slot 11. EFFECT: enhanced efficiency. 3 dwg

Description

Изобретение относится к области сжигания топлива и может быть использовано в котлах, печах и других топливосжигающих устройствах. The invention relates to the field of fuel combustion and can be used in boilers, furnaces and other fuel-burning devices.

Целью изобретения является повышение экономичности. The aim of the invention is to increase efficiency.

На фиг.1 изображено топочное устройство, продольный разрез; на фиг.2 разрез А-А на фиг.1; на фиг.3 разрез Б-Б на фиг.1. Figure 1 shows a furnace device, a longitudinal section; figure 2 section aa in figure 1; figure 3 section BB in figure 1.

Топочное устройство содержит вертикальную камеру сгорания 1 с горизонтальной колосниковой решеткой 2 и вращающейся шурующей планкой 3, закрепленной консольно на механизме перемещения, выполненном в виде транспортера 4 с якорной цепью 5. Транспортер 4 расположен вдоль боковой стенки 6 камеры сгорания 1 и заключен в плоский горизонтальный короб 7, который подключен патрубком 8 с шибеpом 9 к источнику воздуха и примыкает к стенках 6, 10 камеры сгорания 1. В стенках 6, 10 в зоне примыкания к ним короба 7 выполнена сплошная прорезь 11. Камера сгорания снабжена течкой 12 для вывода шлака. Под решеткой 2 размещен воздушный короб 13 с патрубком 14 подвода воздуха, снабженным шибером 15. The combustion device contains a vertical combustion chamber 1 with a horizontal grate 2 and a rotating screwing bar 3 mounted cantilever on a movement mechanism made in the form of a conveyor 4 with an anchor chain 5. The conveyor 4 is located along the side wall 6 of the combustion chamber 1 and is enclosed in a flat horizontal box 7, which is connected by a pipe 8 with a shutter 9 to the air source and is adjacent to the walls 6, 10 of the combustion chamber 1. In the walls 6, 10 in the adjoining zone of the duct 7 there is a continuous slot 11. The combustion chamber is equipped with estrus wife 12 to remove slag. Under the grill 2 there is an air box 13 with a pipe 14 for supplying air, equipped with a gate 15.

Устройство работает следующим образом. The device operates as follows.

Топливо, находящееся на решетке 2, продувается воздухом, подаваемым по коробу 13. Расход воздуха устанавливается шибером 15 так, чтобы из слоя выдувались некоторые фракции топлива в объем камеры сгорания, где они сгорают. Оставшиеся кусочки топлива по мере их сгорания перемещаются шурующей планкой 3 за несколько проходов, вдоль решетки 2. При этом слой топлива перемешивается, а очаговые остатки сбрасываются в течку 12. The fuel located on the grill 2 is blown by the air supplied through the duct 13. The air flow rate is set by the gate 15 so that some fractions of the fuel are blown out of the layer into the volume of the combustion chamber where they burn. The remaining pieces of fuel as they are burned are moved with a screwing strap 3 in several passes along the grill 2. In this case, the fuel layer is mixed, and the focal residues are discharged into estrus 12.

Перемещение планки 3 производится с помощью якорной цепи 5 транспортера 4. При попадании крупного куска между планкой 3 и решеткой 2 планка 3 перемещается вверх и назад, что позволяет преодолеть преграду. Такому перемещению планки 3 способствует выполнение прорези 11 в виде направляющих, а также крепление планки 3 к звену якорной цепи 5 так, что одно звено может поворачиваться по отношению к цепи 5. Часть воздуха через патрубок подается в короб 7, а затем через прорезь 11 в топку. Расход воздуха регулируется с помощью шибера 9 так, чтобы частицы топлива или породы не попадали в прорезь 11. Moving the strap 3 is carried out using the anchor chain 5 of the conveyor 4. When a large piece gets between the strap 3 and the grill 2, the strap 3 moves up and back, which allows you to overcome the obstacle. This movement of the strip 3 is facilitated by the implementation of the slot 11 in the form of guides, as well as the fastening of the strip 3 to the link of the anchor chain 5 so that one link can rotate with respect to the chain 5. A part of the air through the pipe is fed into the box 7, and then through the slot 11 into firebox. The air flow is regulated using a gate 9 so that particles of fuel or rock do not fall into the slot 11.

Claims
