J. s. ATKINSON REFUSE DESTRUCTOR FURNACE Filed May 29 1922 atented Apr. 29, 1924.
UlTED STATES PATENT OFFICE.
Application filed Kay 29, 1922. Serial 1%. 564,588.
To all whom it may concern:
Be it known that 1, JAMES STANLEY ATKINSON, a subject of the King of Great Britain and Ireland, and resident of London, England, have invented new and useful Improvements Relating to Refuse-Destructor Furnaces, of which the following-is a specification.
This invention has relation to refuse dcstructor furnaces and it has for its object the provision of means whereby the destruction of towns or other refuse or other low grade fuel (hereinafter referred to as fuel) is effected in an improved manner.
In accordance with this invention, the re fuse is first subjected to a heat treatment to drive off the contained moisture and is then consumed in the presence of preheated air. The drying of the refuse is effected either by preheated air or by heat contained in the products of combustion of the refuse and the preheating of the air used for the drying and in the combustion of the refuse is effected by the utilization of the heat contained in the clinker resulting from the combustion of the refuse.
The combustion of refuse, in accordance with this invention, is eiiected in a rotary apparatus.
In order that the invention may be clearly and readily understood, reference will now be made to the accompanying illustrative drawin The drawing is a sectional elevational view of an embodiment of the invention;
The refuse to be consumed is delivered to a receiver 1 from which it is fed continuously or from time to time to the one end of a cylinder 2. The cylinder 2 is mounted at two or more points in its length on roller bearings 3 and is rotated thereon by an electric motor 4 and gearing 5. The mounting of the cylinder 2 is such that its longitudinal axis is inclined to the horizontal. The ends of the cylinder 2 enter recesses in walls 6, 7 the wall 6 carries the receiver 1 and has a duct or assage 8 which connects the receiver 1 with the higher end of the cylinder 2. The lower end of the cylinder 2 is in connection by a duct or passage 9 in the wall 7 with an intermediate receiver 10. Each of the receivers 1, 10 is provided with upper and lower closures, the closure of each receiver being connected together in suchwise that they cannot be opened simultaneously, thus preventing escape of v from the cylinder 2 or entrance of air thereto. 11 are the interconnected closures of the receiver 1 and 12 are the similar closures of the receiver 10. The cylinder 2 is perforated as shown for the w ole or a portion of its length and is also jacketed, t e jacket 24 extending the whole or a portion of the len h' of the cylinder 2. The cylinder 2 constitutes the drymg cylinder in which the refuse is dried prior to its combustion in a second cylinder 13 which constitutes the grate. The cylinder 13 is mounted and driven similarly to the cylinder 2, its upper end extending into a recess in the wal 7 which is in communication with the intermediate receiver 10 by a duct or passage 14. The lower end of the cylinder 13 opens into a combustion chamber 15 and is also in connection with a clinker chamber whichis constituted of a cylinder 16 mounted and driven in the same manner as are the cylinders 2, 13. The upper end of the cylinder 16 enters the combustion chamber 15 and its lower end is closed by a door or wall in which are assages that connect the jacket 20 with w ich the cylinder is provided with the atmos here. .The lower end of the cylinder 13 an the upper end of the cylinder 16 are connected by a chute 17 that extends across the combustion chamber 15. The lower portion of the combustion chamber 15 forms a dust chamber 18 and is provided with a removable closure 18. The cylinder 13 is perforated like thecylinder 2 and has a jacket 19. The jacket 20 of the clinker chamber 16 is in communication at its upper end with the jacket 19 of the cylinder 13. The jacket 24 of the cylinder 2 is in connection by a pipe 21 with the uptake or waste heat outlet of the steam generator or other apparatus in which the heat generated by the combustion of the refuse in the cylinder 13 is utilized. The products of combustion and waste gases are thus passed in whole or in part to the jacket 24 and enter the cylinder 2, in admixture or not with the atmospheric air. The cylinder 2 is in connection with a condenser 23 through which the gases driven oil from the refuse by the heat ap. plied by means of the waste gases and products of combustion or the mixture of air and waste gases and products of combustion are passed by a fan 27 and in which any condensible vapours are condensed, the non-condensible gases and vapours being delivered by the fan 27 to the combustion chamber 15.
refuse dried in the cylinder 2 is consumed in the cylinder 13 and the resulting clinker is delivered to the clinker chamber 16, the heat contained in the clinker being used toheat the air passing through the jacket 20. The clinker passes'through the clinker chamber 16, is broken up by the rotary movement thereof and is then discharged. The cylinder 13 may be lined with fire brick or the refuse may be indirect contact with its inner wall, which wall, as before stated, is perforated, as also are the fire bricks, when used, so that the heated air delivered to the jacket 19 may pass directly among the refuse for its combustion.
In some cases, the cylinder 2 may be imperforate in which case the waste gases and products of combustion do not come into agtual contact with the refuse. Also instead o 1181 combustion to dry the refuse, air heated by the waste gases and products of.
the clinker may be used for the purpose, such preheated air being used in admixture or not with air at atmospheric temperature. If the refuse be in a very moist condition when introduced into the cylinder 2, it may be necessary to use the whole of the clinker heated air for its drying, in which case the air for combustion of the refuse would be drawn from another source and be preheated or not.
What I claim is A refuse destructor furnace comprising a jacketed and rotatable drying cylinder, a jacketed and rotatable grate cylinder, said cylinders being in connection with one another, a jacketed and rotatable clinker cylinder and a connection between the jackets of the grate and clinker cylinders.-
Dated this 9th day of May 1922.
