LIMEKILN.
SPECIFICATION forming part of Letters Patent No. d43,779, dated December 30, 1890.
Application filed June 21, 1890. Serial No. 356,227. (No model.)
OER, a citizen of the United States, residing;
at Quincy, in the county of Adams and State of Illinois, haveinvented certain new and useful Improvements in Limekilns, of whielrthe following is a specification.
My invention relates to certain improvements in limekilns and supplying steam to the furnace of said kilns.
The object is to provide for steam without increasing the combustion of fuel, and by employing the steam to increase the draft and enable a cheaper quality of coal to be used. By my arrangement and construction of parts the process of lime-burning is cheapened.
The invention is shown in the drawings, in which- Figure 1 is a vertical section of a continuously-burning limekiln and my improvements. Fig. 2 is a front elevation of the limekiln, showing the boiler. Fig. 3 is a horizontal section of the kiln on line 3 3.
The limekiln comprises a barrel A, one or more furnaces B, grates'C, ash-pit D, and walls E. These parts may be of any approved model or design arranged for continuously burning lime or cement. The entire width of the furnace B opens through the front wall E. Adjoining the furnace B and partly on or against the outside of the wall above the furnace is a flat narrow upright boiler F, which covers and closes the open front of the furnace and is supported on brick piers G or other suitable support. In the present instance the sides and top of the boiler F are inclosed by brick H. The boiler F has a doorhole I through it. This door-hole gives access to the furnace, and the fuel is passed therethrough. A door I closes the door-hole and may be arranged to work in any desired manner. In the present instance this door works up and down in a guideway a. The water-chamber F of the boiler F entirely surrounds the door-hole I. By making the furnace and boiler in this manner the boiler assists in closing the open end of the furnace, which gives it the benefit of some of the heat directly from the furnace-fire. It also enables the furnace to be torn down and rebuilt without disturbing the boiler, which could not be done if it were built into the Wall or Were permanently connected with it any way. Itis not affected by any movement of the walls of the furnace in long-continued use or heating, which must necessarily cause settling or change in the walls, until finally they have to be torn down. The opening or door through the boiler into the furnace permits of the Water circulating entirely around the boiler and gives a good substantial support for the door. The boiler has a supply-pipe b, a steam-gage c, and a water-gage d. A pipe 6 leads from the dome or top of the boiler, and a branch 6 extends first downward and then horizontally across the boiler-front and has a cock or valve f, and two jet-pipes e branch from and pass horizontally through the lower part of the boiler F and into the f urnaceB above the grate. Each of these two pipes e at its inner end has jet-apertures or a spray-nozzle of some suitable kind to deliver a blast of dry steam into the furnace, which will serve to increase the draft, and by its decomposition and formation of carbureted hydrogen provide a burning-gas that will intensify the heat. A pipe 6 may lead from the steam-pipee around the kiln to another side, where jet-pipes may enter another furnace, as shown.
The heat of the furnace and the heated wall serve to heat the boiler F. Thus the boiler is heated without direct expense.
l-Iaving described my invention, I claim The combination, with a limekiln-furnace having its front end open, of a flat upright boiler upon the exterior of the wall and closing the open end of the furnace, said boiler being provided with a door-hole opening through it, whereby access is had to the furnace and the water may circulate entirely around the fire, and a steam-pipe leading from the boiler to the furnace-grate for supplying the fire with dry steam, substantially as described.
I In testimony whereof I affix my signature in the presence of two witnesses.
CHARLES ALBERT MERCER.
