Abstract

A steam generating system comprising an enlarged water tank receiving an elongated fire tube therethrough. The fire tube has a burner and steam coil mounted on a movable frame therein and selectively retractable therefrom into an enclosed control room provided at one end of the water tank and including controls, pump means, cleaning means, and the like. The fire tube acts so as to preheat the water subsequently pumped from the tank and through the steam generating coil for ultimate discharge from the system.

Claims

1. A steam generating system comprising a water supply containing water tank, an elongated fire tube extending through said tank for a preheating of the water therein, said fire tube having opposed ends communicating with the exterior of said tank at a pair of spaced points, a heat source and an associated steam coil, means mounting said heat source and steam coil within a first end portion of said fire tube, said coil being orientated inward of said heat source along the flow path of the heat produced by the heat source, the second end portion of said fire tube constituting a discharge flue, water line means communicating the water supply with the steam coil, steam discharge line means extending from said steam coil, a control room mounted adjacent said water tank, the first end portion of said fire tube extending into said control room, and closure means mounted on said fire tube and selectively closing the first end thereof, the means mounting said heat source and steam coil comprising a frame Movably mounted within the fire tube and selectively projectable beyond the first end thereof for at least a partial withdrawal of the heat source and steam coil from the fire tube.

2. The system of claim 1 wherein said fire tube comprises a horizontal section extending inwardly from the first end thereof, and a vertical section extending vertically upward from the horizontal section at the end thereof remote from the first end of the fire tube, said vertical section terminating at the second end of the fire tube outward of the water tank.

3. The system of claim 2 including means for selectively communicating the steam discharge line means with the water supply to provide a circulating system and an accelerated preheating of the water supply.

4. The system of claim 3 including a mobile base supporting said water tank and said control room.

5. The system of claim 4 wherein the water tank and control room are formed in a continuous cylindrical housing with opposed end walls and an internal bulkhead dividing the housing into the tank and control room.

6. The system of claim 5 including a fuel supply tank mounted on said mobile base, and fuel supply line means communicating the fuel supply tank with the heat source.

7. The system of claim 6 including a chemical supply tank mounted within the control room, and means associated with the chemical supply tank for a selective flushing of the steam coil with the contents thereof.

8. The system of claim 7 wherein the second end of the fire tube projects a substantial distance above the water tank and terminates in a flue cap, said flue cap being pivotally mounted on the fire tube and selectively collapsible downwardly so as to reduce the overall height of the apparatus.

9. The system of claim 8 wherein the water tank and control room are exteriorly insulated.

10. The system of claim 9 wherein said steam coil is positioned solely within the horizontal fire tube section, said fire tube being of a substantially constant cross section throughout the full length thereof.

11. A steam generating system comprising a water supply containing water tank, an elongated fire tube extending through said tank for a preheating of the water therein, said fire tube having opposed ends communicating with the exterior of said tank at a pair of spaced points, a heat source and an associated steam coil, means mounting said heat source and steam coil within a first end portion of said fire tube, said coil being orientated inward of said heat source along the flow path of the heat produced by the heat source, the second end portion of said fire tube constituting a discharge flue, water line means communicating the water supply with the steam coil, and steam discharge line means extending from said steam coil, the means mounting said heat source and steam coil comprising a frame movably mounted within the fire tube and selectively projectable beyond the first end thereof for at least a partial withdrawal of the heat source and steam coil from the fire tube.

12. A steam generating system comprising a water supply containing water tank, an elongated fire tube extending through said tank for a preheating of the water therein, said fire tube having opposed ends communicating with the exterior of said tank at a pair of spaced points, a heat source and an associated steam coil, means mounting said heat source and steam coil with a first end portion of said fire tube, said coil being orientated inward of said heat source along the flow path of the heat produced by the heat source, the second end portion of said fire tube constituting a discharge flue, water line means communicating the water supply with the steam coil, and steam discharge line means extending from said steam coil, said fire tube comprising a horizontal section extending inwardly from the first end thereof, and a vertical section extending vertically upward from the horizontal section at the end thereof remote from the first end of the fire tube, said vertical section tErminating at the second end of the fire tube outward of the water tank.

13. The system of claim 12 wherein said steam coil is positioned solely within the horizontal fire tube section, said fire tube being of a substantially constant cross section throughout the full length thereof.

14. A steam generating system comprising a water supply containing water tank, an elongated fire tube extending through said tank for a preheating of the water therein, said fire tube having opposed ends communicating with the exterior of said tank at a pair of spaced points, a heat source and an associated steam coil, means mounting said heat source and steam coil within a first end portion of said fire tube, said coil being orientated inward of said heat source along the flow path of the heat produced by the heat source, the second end portion of said fire tube constituting a discharge flue, water line means communicating the water supply with the steam coil, steam discharge line means extending from said steam coil, and means for selectively communicating the steam discharge line means with the water supply to provide a circulating system and an accelerated preheating of the water supply.

15. A steam generating system comprising a water supply containing water tank, an elongated fire tube extending through said tank for a preheating of the water therein, said fire tube having opposed ends communicating with the exterior of said tank at a pair of spaced points, a heat source and an associated steam coil, means mounting said heat source and steam coil within a first end portion of said fire tube, said coil being orientated inward of said heat source along the flow path of the heat produced by the heat source, the second end portion of said fire tube constituting a discharge flue, water line means communicating the water supply with the steam coil, and steam discharge line means extending from said steam coil, the water tank and control room being formed in a continuous cylindrical housing with opposed end walls and an internal bulkhead dividing the housing into the tank and control room.

16. The system of claim 15 including a chemical supply tank mounted within the control room, and means associated with the chemical supply tank for a selective flushing of the steam coil with the contents thereof.
