Definitions

  • a vapor generator is disclosed as having a burner arranged in the forward end of a fire box extending long1- tudinally of the furnace.
  • a pair of spaced mains extend parallel to the longitudinal direction of the fire box, and the fire box communicates with one of these mains.
  • the two mains are interconnected by a plurality of ducts extending in parallel relation between the two mains.
  • the second of the two mains has an outlet connected to the ue.
  • This invention relates in general to the construction of vapor generators, and in particular to a new and useful vapor generator having a plurality of heating gas passages arranged so that the total length of gas flow is substantially the same for each gas passage.
  • the flue are arranged such that the rearmost sections carry the largest amount of theflue gas, simply because, after burning, the gases pass through the rearmost section on the shortest path up through the chimney.
  • the velocities of the flue paths are highest at the rearmost section at the location which is furthermost from theoil burner head.
  • the fine gases at the rearmost sections also have the highest temperatures and give off the greatest amount of heat to the heating water. The heating surfaces are thus irregularly stressed and the boiler not fully utilized.
  • the discharge of the second collecting main is to a chimney connection at its outermost end so that, regardles of which interconnecting or cross passage the gas flows through, it must travel over the same fiow distance in order to traverse a portion of the first collecting main, an interconnecting passage and the remaining portion of the second collecting main to travel to the chimney.
  • a further object of the invention is to provide a vapor generator having a plurality of gas passages or mains arranged substantially parallel to a fire box with a connect- 3,368,531 Patented Feb. 13, 1968 ing passage from the fire box to the first gas main which is located adjacent the burner head so that combustion gases which are generated in the fire box must flow backwardly toward the head and into the first gas passage, and which further includes' a plurality of interconnecting passages between two spaced mains which are parallel to the fire box, which interconnecting passages extend at a right angle to the fire box axis, and with an additional connection of the last parallel main to the chimney, so that the gas flow will be through a portion of each of the parallel gas paths and through any one of the plurality of interconnecting passages so that the total flow of gas distance, regardless of which interconnecting passage it moves through, from the fire box to the chimney will be the same.
  • a further object of the invention is to provide a vapor generator which is simple in design, rugged in construction and economical to manufacture.
  • FIG. 1 is a longitudinal sectional view of a boiler constructed in accordance with the invention
  • FIG. 2 is a transverse sectional view of another embodiment of boiler constructed in accordance with the invention.
  • FIG. 1 the invention embodied therein in FIG. 1 includes a boiler, generally designated 10, having a front wall 12 in which is mounted an oil burner 14.
  • the oil burner 14 includes a head portion 16 which is located within a substantially cylindrical fire box 18.
  • the major portion of the fire box 18 is surrounded by the liquid containing portion of the boiler and it includes a connection 20 through which combustion gases which are generated in the fire box 18 may flow into a first gas passage or main 22, which is elongated in the same direction as the fire box 18.
  • the second gas path or main 24 is arranged substantially parallel to the longitudinal axis of the main 22 and the fire box 18 and it is connected at the rear end thereof, adjacent the rear wall 26 of the furnace, to a chimney or fine 30.
  • a plurality of interconnecting passages 32 which extend substantially normal to the axes of the mains 22 and 24, interconnect the two mains and provide separate flow passages for portions of the line. gases therebetween.
  • a boiler 10 having a fire box 18 which communicates adjacent the front wall (not shown) with two spaced collecting mains 22, 22, which are located below the fire box 18'.
  • a plurality of passages 32 interconnect the lowermost collecting mains 22', 22 with uppermost collecting mains 24', 24'.
  • the two uppermost collecting main 24, 24' are connected to a chimney or flue 30' adjacent the rear wall of the furnace (not shown).
  • the combustion gases must thus first flow from the fire box 18 to one or die other of the lowermost collecting mains 22, 22. Thereafter, the gases flow up along the pasages 32, 32 into the uppermost collecting mains 24', 24.
  • the interconnecting passages 32' between each of the mains 22' and 24' are arranged in a manner similar to that indicated in FIG. 1 so that there will be equal distance of gas flow for the flue gases regardless of which one of the connecting passages 32' the gas flows through to the chimney 30'.
  • the collecting mains 22 and 24 may be of cylindrical configuration and provide equal flow area, and the passages 32 which interconnect the mains may also provide for equal flow area therethrough. In this manner, the gas is evenly distributed through the collecting mains and the interconnecting passages in its flow path to the chimney. Thus, a uniform distribution of the flue gases over all of the heating surfaces is achieved.
  • the fire box, the collecting mains and the cross passages are all surrounded by liquid to be vaporized, and the walls thereof thus represent separate heating surfaces.
  • a vapor generator constructed in this manner will thus provide uniform distribution of the heating power throughout.
  • the fire box, collecting mains and the interconnecting ducts may be formed of cast iron or may have a welded steel construction. Also, the vapor generator may be designed as a sectional generator formed by a plurality of individual sectional elements arranged in a longitudinal direction from one side of the boiler to the other.
  • a vapor generator comprising a casing defining a chamber of liquid to be vaporized, a tubular fire box extending into the liquid chamber from one side of said casing, means for directing high temperature gases into said fire box from the one side of said casing, a plurality of collecting mains elongated in substantially the same direction as said fire box and arranged in spaced substantially parallel relationship, a plurality of ducts defining gas flow passages interconnecting adjacent ones of said collecting mains at spaced locations along the length thereof, passage means formed adjacent said one side of said casing defining a high temperature gas passage between s'aid fire box and an adjacent one of said collectthe adjacent one of said collecting means, and a flue connected to the last one of said collecting mains adjacent the end thereof remote from the said one side of said casing, whereby the gases, after issuing from said fire box, must traverse a part of one of said collecting mains, then through one of said plurality of interconnecting ducts and then must flow the remaining distance of the next adjacent collecting main to said
  • a vapor generator according to claim 1 wherein said collecting mains are arranged substantially parallel to said fire box and said interconnecting ducts extend substantially perpendicular to said collecting main.
  • a vapor generator according to claim 1 wherein said generator is designed as a sectional generator formed by a plurality of individual sectional elements arranged in a longitudinal direction from one side of said boiler to the other.
  • a vapor generator according to claim 1 wherein said casing, said fire box, said ducts and said collecting mains are formed of a steel-welded construction.
  • a vapor generator according to claim 1, wherein said plurality of ducts comprises a first duct adjacent said fire box and extending substantially parallel thereto, and a second duct spaced from said first duct and extending substantially parallel to said first duct and said fire box.
  • said plurality of collecting mains includes first and second collecting mains arranged on each side of said fire box and connected adjacent said one side of said casing to said fire box, and third and fourth collecting m'ains arranged adjacent the upper portion of said fire box, said interconnecting ducts connecting said first and third collecting mains and said second and fourth collecting mains, respectively.
  • a vapor generator according to claim 8 wherein said means for directing high temperature gases into said fire box includes an oil burner and wherein said interconnecting ducts extend substantially vertically in said casing.
