Document Type and Number:
Japanese Patent JP3477244
Kind Code:
B2
Abstract:
PURPOSE: To obviate large lumpy slag-bite inability of a roll crusher and prevent slag accumulation in a coal gasification oven equipped with the coal gasification oven body, an external pressure vessel surrounding the body, a slag hopper communicating with the lower part of the pressure vessel and filled with water, and the roll crusher to crush falling slag inside the slag hopper.
CONSTITUTION: This slag nipping crusher is designed so as to be equipped with a pair of hydraulic jacks 9 set up horizontally facing to each other in a hopper, a spreader at the tip of the rod of the each hydraulic jack 9, teeth fitted to the respective spreaders, and a hydraulic unit to move the jacks 9 simultaneously toward the center. Slag falling from the coal gasification oven body is nipped between the spreaders facing to each other and crushed with the teeth, and the crushed slag is then fed to a roll crusher 5 situated under the spreaders.
