Application filed septemlier 22, 1911. Serial No. 658,856.
T all whom it may concern:
Be it known that we, ERNEST H. PnABonY and DAVID J. Intel-I, citizens of the United States, residing at New York city, borough of Manhattan, county of New York, and State of New York, and New York city, borough of Richmond, county of Richmond, and State of New York, respectively, have invented certain new and useful Improvements in Apparatus for Burning Finely- Divided Fuel, of which the following is a specification.
In certain situations steam boiler furnaces are equipped with the regular grate bars for firing with coal. and with means for firing with finely-divided fuel, such as oil, in combination therewithf Ordinarily these furnaces may be fired with coal. Should, how ever, the necessity for increasing steam capacity arise, the oil-burning apparatus is put into operation. Usually there is a dead space between the fire doors made up of a cast iron air-cooled casing or of bricleu'ork. This dead space may be utilized for locating" the oil burners: that is, the burners may be inserted through the casing! or brick-work, the tip of the burners projectin into the furnace. To this event there is no provision for protecting the burners from the heat of the "furnace when not in service except by admitting, a large excess of air about the burners with consequent deleterious effects on' the eiliciencv, or by disconnci'iting the burners entirely and removing them from the boiler. If this is not done when firing, with coal alone, the oil-burning apparatus is subjected to the furnace heat. and is liable to be deteriorated thereby. lllorcovcr, the oil standing in the burner bcci'nncs carboir izcd and the usefulness of the burner thereby destroyed, such burner requiring clcaninp before it can be again used.
lhc object of the present invention is to hrovide an adcouate protection for the burn on: in boiler furnaces which are equipped for a portion of the burners may be in use and it becomes necessary to protect from the radiant heat. of the furnace those burners which are not in use,
Duiinvention, therefore, relates to furnaces burning oil only as well as those in combination with coal.
The invention will be understood by reference to the accompanying drawings in which Figure l is a front view of a furnace for burning coal and oil in combination; Fig. 2 a vertical section on the plane of the line 2-2 of Fig. 1; Fig. 3 a horizontal section on the plane of the line 3-3 of Fig. 1; Fig. 4 an enlarged vertical section on the plane of the line 4-4l of Fig. 3, and Fig. 5 a front view of the burner protecting plate.
Similar reference numerals indicate sim lar parts in the several views.
Referring to the drawings, the numerals l and 9 designate the usual coal firing doors of a boiler furnace. Between these doors is placed a cast iron furnace front casing 3 which we have modified for the protection of the oil burner in the followinginanner; as shown in Figs. 2 and 4, the sup l y pipe 2., to which the burner 5 is attached is led through a. suitable opening in the front wall of the casing, the burner 5 terminating within the casing s ace. In connection with the burner an air deflecting plate 6 is preferably used consisting of a plurality of blades set at an angle to the plane of their support and designed to deflect the air for combustion from its normal direction of travel, and to impart to it a whirling or rotating motion.
JERSEY, A CORPGRATIGN OF To provide for the adequate protection of i the burner and to obviate, therefore. the necessity of removing it to prevent deterioration when the furnace is fired with coal alone, we place in the opening on the fnrits position by band.
notch, it may be slid down, as indicated in Fig. 2, and by dotted lines in Fig. 4:. When firing by coal alone, the casting is raised to its full line position, thus protecting the 5 burner from the furnace heat. A door is pivotally hung or hinged in the front wall of the casing to provide for the admission of air for combustion to the burner. In Fig. 4 the door is shown open.
Heretofore, so far as we are aware, the oil pipe has been run straight through the easing into the furnace, and we are the first to locate the burner within the casing space and to provide means which do away with the necessity of the removal of the burner when firing with coal alone to prevent the destruction or deterioration of the burner. The removal of the burner has heretofore involved considerable ,labor and possible loss of time and loss of use of the burner at a time when its use may be very essential.
It is obvious that the protecting block or casting may be supported in other ways than that shown, and that such expedient used as a fuel. a I What we claim and desire to secure by Letters Patent of the United States is:;
1. A furnace casing having an opening, a. 80 burner for finely divided fuel terminating within the interior of said casi and'a refractory block or casting adapted be sup- In testimony may be used in furnaces wherein oil only is ported within the casing when the burner is in use, said casing having a seat to receive said block when placed into said opening in front of the burner.
12. A furnace casing having an opening, a burner for finely divided fuel terminating Within the interior of said casing, and a removable refractory block or casting adapted to be set into said opening in front of the burner, said block or casting having an offset to engage a recess in the casing when the former is placed in position to protect the burner.
3. A furnace easing having an openin", a burner for finely divided fuel terminating within the interior of said casing, a refractory block or casting adapted to be supported within the casing when the burner is in use, said casing having a 'seat to receive said block or casting when raised into said opening in front of the burner, and a door in the front wall of said casing to provide for the admission of air for combustion.
whereof we have hereunto signed our names in the presence of two subscribing witnesses.
