Rocking furnace grate

Abstract

The invention discloses a rotational type furnace grate, which belongs to a device for burning patch fuel in a furnace. The rotational type furnace grate is characterized in that the rotational type furnace grate is formed by furnace bars with stripy teeth, and the furnace bars are arranged into parallel rows. In case of operation, the furnace grate is mounted in a burning furnace, fuel is placed on the furnace grate, the rotation of the furnace bars in the furnace grate is controlled according to the burned condition of the fuel, and burned dusts and slag are dropped in the bottom portion of the furnace body under the furnace grate via gaps among the furnace bars and the rotation. Each furnace bar in the furnace grate of the invention is designed to be rotational, thereby mechanically discharging dusts and slag which can not be dropped by controlling the rotation during the operation, and the structure is better for complementing air for the lower end of the furnace grate to support combustion, thereby achieving the purpose of more completely burning.

Description

technical field [0001] The invention relates to equipment for burning block fuel in a furnace, in particular to a rotary grate. Background technique [0002] The grate is an important equipment in the furnace. Usually, many grates made of cast iron are arranged side by side, and several rows are combined to form a grate, which is placed in the lower part of the furnace. The fuel is laid on the upper part for combustion, and the air required for the combustion process enters the combustion layer from the lower part of the grate through the gap between the bars. There are fixed type, shaking type, vibrating type and mobile type. The grate is fixedly installed at the lower part of the furnace, and the ash and slag after the fuel is burnt fall through the gap between the grate, and the slag is picked out from the front end of the grate, which is called "fixed grate"; the grate is arranged side by side on the shaft Above, it is called "pendulum or vibrating grate" by means of c...
