METHOD OF FIRING OF CLAYWARE AND DEVICE FOR ITS EMBODIMENT Russian patent published in 1998 - IPC

FIELD: firing of clay bricks. SUBSTANCE: the offered method includes formation of channels in brick setting, supply of heat carrier to brick setting and to its channels, in this case, heat carrier is introduced directionally and in definite quantities by means of nozzle device through which energy carrier is supplied; ejecting and injecting of furnace gases in brick setting channels. Uniform distribution of heat carrier is effected by raising and lowering of nozzle device in channels of article setting. In addition, introduced into channels may be combustible substance, for instance, natural gas. Bell-type furnace has lined cap 1 with gas burners 2, heat gas-tight seal 4, backing 6 for installation of setting 7 with vertical channels 8 and horizontal channels 9 to pass furnace gases. Cap 1 is installed by lowering on rolling finger-car 3 with the help of hoisting mechanism 5. Installed in upper part of cap 1 is nozzle device 10 made in form of a system of pipes 11 oriented along the axis of vertical channels 8 for lowering and hoisting. Located coaxially inside pipes 11 are pipes 12 for supply of combustible substance. Pipes 12 are installed for motion with respect to pipes 11. Lower part of cap 1 has channels for smoke discharge. EFFECT: higher efficiency of firing process. 2 cl, 2 dwg
