application filed June 26, 1817. Serial No. 1711068.
' To all whom it maycancem:
- Be it known that I, DAVID R. Bonn, a Cltlr zen of the United States of America, residing at Oglesby, in the'county of Coryell and State of Texas, have invented certain new and useful Improvements in Heat-Producing Processes, of which the following is a specification.
My invention relates to a process of producing heat and conserving heat for use in kilns. furnaces for burning lime, furnaces for boilers, furnaces formanufacturing enterpi'ises, and for similar purposes; and the object is to provide a process of increasing 35 the number of heat units-from fuel and for conserving the heat when produced, to provide a process of burning fuel without Wasting' the heat units, to provide a process of burning fuel whereby the cheaper as well as,
the'better grades of fuelwill produce more heat, in proportion to the amount of fuel burned; and to provide a process'of burning fuel" wherein cold air is excluded from'the burning of thefuel. The patent issued to 2% me on June 12, 1917., No. 1,229,706, shows how such process is carried out in practice. Gther objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.
Reference is bad to the accompanying drawings which fonna part of this application'.
Figure 1 isa vertical section of a furnace and apparatus for burning fuel and preheating the air, showing a kiln in conventional form connected to the furnace. Fig. 2 is an enlarged sectional View of a sicker. Fig. 3 is a longitudinal section of the revolving 46 feeder.
Similar characters of reference are used to indicate the same parts throughout the several view".
The results of the process herein described 5 are obtained by feeding the fuel to the coinbustion chamber in a powdered form and byletting only preheated air into the combustion chamber and excluding cold or unheated air from the combustion chamber. Generally, the heat 18 produced in a difierent chamber from the chamber in which the heat is to be utilized. In the drawings. a kiln 1 is shown in conventional form provided with a flue 8. A furnace 4 is provided with grate bars 5. a doorfi. and stokers 7. Instead of placing an ash-box under the grate bars 5. asusual. a chute 8 is providedwith afiared upper end or mouth 9 to receive the ashes and hotembers which fall through the grate bars 5- The ashes fall down the inclined chute to a box 10 from which they can be removed through a door 11. Provision is made for a fire within. the box 10. Grate bars 12 are provided for receiving the fuel and supporting the same for combustion.
The object of the fire in the box 10 is to heat all air that is fed to the furnace 4. The air is heated not only by the fire which is maintained in the box 10. but is also heated by the embers which fall through the grate bars .5. The box 10 is provided with a door 13.-
which may be used for supplying fuel to the fire on the grate bars 12 and for admission of air which is to be heated. The heated air ,will rise up through the fuel 14 which is being consumed in the furnace 4. The fuel for furnace 4 is preferably fed in powdered form by means of stokers 7. The fuel will fall into the fire zone 15 where lie particles of fuel will be oxidized and largely converted into gas. The heat and burning gases pass directly into the kiln 1. A plurality of Stoker's 7 may be provided and each stoken consists of a casing 16 with openings 17 into a hopper 18 which contains fuel and corresponding openings 19 for dropping the fuel into the firezone 15 within furnace 4. The fuel is fed by a revolving feeder 20. The feeder 20 may be revolved by any suitable means. In operation. a cavity 21 formed in thefeeder will be turned to an opening 17 in the casino; 15 and instantly a charge of fuel will fill the cavity 21 in the feeder and on continuous revolving of the feeder. the charge of fuel will be dumped into the fur- 16. and on each revolution of the feeder 20.
each cavity 21 will 'atll'era charge of fuel and dump the ear .nto the furnace 4. In
' nace l through the opening 19 in the casing $110M Pipes may be connected with furnace a A valve 0 damper :24 is prgviglgd 0? g plating the fiow'of heated air through the,
. from the grate bars The a r w ll thu preheated before. it comes co t w h the fuel in the furnace 4 where the principal combustion takes place. The cold air or air in the normal condition is thus excluded andonly preheated air is let into the furnace or combustion chamber. The burnin of the fuel will create the nec ssary draft force the heat and burning gases'into the kiln 1.
is subjected tga process of preheat-- and after'the air is thus treated, only such quantity of air as is necessary and no more than is needed is allowed to enter the combustion chamber for oxidizing the contents of the chamber. The excluding of the cold air from the furnace or.'combustion chamber is important because the combustion will not be impeded or hindered by the cold air which would absorb heat units. The heat produced is-thus conserved, as the heat will not be consumed in heating cold air. The gases created by the burning fuel are prgtegted from being impaired for heating purposes because they are not exposed to air which has not been preheated. A successful process has been developed for securing a complete combustion of all the-gases as they are being produced, thus conserving and preventing any waste of heat units. The process is smokeless because all the fuel partitles will be consumed. The combustion chamber may be connected with a kiln, as shown, or the heat created in the combustion chamber can be forced into any other furnace 'or place for use for manufacturing or other purposes.
The degree ofheat in the furnace can be regulated by the stoking devices which can beset to feed more or less fuel to .the combustion chamber and by regulating the amount of preheated air which is furnished to the combustion chamber. The amount of preheated air which comes through the chute 8 can be, regulated by the damper 24:- The invention is particularly a' pulverized fuel combustion'process so that all the fuel can be consumed. At the same time oxygen only in sufficient quantities is furnished to comess is dependent on a specially arranged furnace, as shown the drawings, having a ess to be utilized as a fuel eificiently enough for all purposes. The door 6 is not a fuel supply opening generally,-not to be used except for starting a fire on the grate bars 5 to begin the operation. The door 6 is then closed up air-tight and the fuel in powdered form is supplied through the holes 23, as shown in the top of the furnace. No'air passes in with the fuel supply and preheated air necessary for oxidizing is admitted by) way of the chute 8.,- Y What/le1a1m,is "w 1. The herein described process of prmlllcl-v ing and conserving heat which consists-in startinga fire in a chamber and then closing the chamber, feeding fuel by gravity into the chamber 1n powdered form and at'the. same time excluding cold air from said chamber, and supplying preheated air to said chamber.
