A lid assembly for a portable biochar kiln and system is disclosed. An example of a lid assembly includes a cylindrical sidewall, a rim around the cylindrical sidewall, and a top portion having an opening formed therein. A removable stack is configured to fit over the opening formed in the top portion to direct exhaust from the portable biochar kiln. A gasket cover is interchangeable with the removable stack to fit over the opening formed in the top portion to form a substantially airtight seal over the opening formed in the top portion when a burn is complete in the portable biochar kiln to self-extinguish embers in the portable biochar kiln.
摘要:
A coal-charging larry cart for lifting lids out of charging holes in the roof of a coke oven and for cleaning the charging-hole jambs has a lid lifter with a lift magnet and a jamb cleaner with a cleaning head. Respective travel frames are horizontally movable on rails on the cart in a first horizontal direction, and respective support frames inside the respective travel frames are each movable relative to the respective travel frame in a second horizontal direction transverse to the first direction. Respective carriages horizontally displaceable in the first direction on the support frames carry the support arms for horizontal movement of each of the support arms relative to the respective support frame between an operating position in which the lift magnet or the cleaning head is aligned with a charging hole in the roof of the coke oven and a rest position spaced from the charging hole.
