TH25381U - Waste energy biochar kiln - Google Patents

Abstract

OCR waste-to-energy biochar kiln, produced from 200-liter metal drums, consists of 4 main components: gas combustion chamber (1), outer combustion chamber (2), inner charcoal chamber (3), and middle combustion chamber (4), with 4 additional developed sub-assemblies: 1. Inner combustion chamber (17), which functions as a base for the inner charcoal chamber (3) and helps prevent the heat from combustion of waste from directly contacting the wall of the outer combustion chamber (2); 2. Front wind shield (20), which functions to prevent smoke from flowing outside the kiln; 3. Front cover (21) and 4. Rear cover (22) will be installed as auxiliary equipment after combustion is complete to prevent air from flowing in to combust biochar inside the kiln, resulting in a faster cooling period of the kiln.

Claims (9)

OCR 1. Waste-to-energy biochar kiln consists of: Gas combustion chamber (1), which is a cylindrical tube and serves as a gas combustion chamber and an air vent with one air and fuel inlet from wood chips (7), fitted onto the outer combustion chamber (2); the outer combustion chamber (2), which is a cylindrical tank and serves as a fuel container from municipal solid waste, with an outer combustion chamber lid (10) with a locking system and a circular hole in the center for fitting into the middle combustion chamber (4), and an air intake screen at the bottom (6) fixed to the bottom of the outer combustion chamber (2), with one air intake inlet at the front (8) and one air intake inlet at the back (9) containing the inner combustion chamber (3) and the middle combustion chamber (4) inside; the inner combustion chamber (3), which is a cylindrical tank and serves as a container for the raw materials for biochar production (16), with an inner combustion chamber lid (11) without a locking system and a circular hole in the center. The middle part is fitted into the middle combustion chamber (4). The middle combustion chamber (4) is a cylindrical tube and functions as a combustion chamber for wood waste fuel by gasification process, along with the combustion of smoke and gases from the combustion of municipal solid waste fuel (14) by the oxygen combustion process in the outer combustion chamber (2) and gases from the combustion process in the inner charcoal burning chamber (3) by the pyrolysis process. Specifically, the outer combustion chamber (2) is further assembled with the inner waste combustion chamber (17), a front wind shield (20), a front cover (21), and a rear cover (22). The inner waste combustion chamber (17) is the base supporting the inner charcoal burning chamber (3) to prevent heat from The waste is burned in the inner combustion chamber (3) so as not to come into contact with the outer combustion chamber (2), and the inner combustion chamber (17) has a front aeration port (18) and a rear aeration port (19) installed inside the outer combustion chamber (2), and a front wind shield (20) is installed in front of the front aeration port (8), where a front cover (21) is installed in place of the front wind shield (20) after combustion is complete, along with a rear cover (22) installed in front of the rear aeration port (9) to reduce the temperature of the waste-to-energy biochar kiln. 2. Waste-to-energy biochar kiln, according to claim 1, where the inner waste combustion chamber (17) is cylindrical in shape with a diameter of 50-56 centimeters and a height of 20-25 centimeters. 3. Waste-to-energy biochar kiln under claim 1 or 2, where the outer combustion chamber (2) has a front air intake (8) which is a rectangular opening 6-7 centimeters wide and 16-17 centimeters high, located 2-4 centimeters above the bottom edge of the outer combustion chamber (2), and there is a rear air intake (9) on the opposite side which is a square opening 6-7 centimeters wide, located 2-4 centimeters above the bottom edge of the outer combustion chamber (2). 4. Waste-to-energy biochar kiln, according to any one of claims 1 to 3, in which the middle combustion chamber (4) has 2 ignition openings for municipal solid waste fuel (12), which are rectangular openings with a width of 1-1.5 centimeters and a height of 4-6 centimeters, located 1-3 centimeters above the bottom edge of the middle combustion chamber (4), and there is 1 air intake opening (13) located in the middle between the 2 ignition openings for municipal solid waste fuel (12), which are rectangular openings with a width of 4-6 centimeters and a height of 15-17 centimeters, located 1-3 centimeters above the bottom edge of the middle combustion chamber (4). 5. Waste-to-energy biochar kiln under any of the claims 1 to 4, in which the middle combustion chamber (4) has a smoke extraction pipe (5) which is a square metal pipe of size 2x4 inches or 5x10 centimeters with a length of 16-19 centimeters attached to the front of the inner air intake port (13). 6. Waste-to-energy biochar kiln under any one of claims 1 to 5, where the outer combustion chamber (2) is the same size as a 200-liter metal tank. 7. Waste-to-energy biochar kiln under any of the claims 1 to 6, where the gas combustion chamber (1) has a diameter of 25-30 centimeters and a height of 120-150 centimeters. 8. Waste energy biochar kiln under any of the claims 1 to 7, where the inner combustion chamber (3) has a diameter of 50-56 centimeters and a height of 55-60 centimeters. 9. Waste-to-energy biochar kiln under any one of claims 1 to 8, in which the middle combustion chamber (4) has a diameter of 5-7 inches and a height of 90-95 centimeters.
