Steam supply apparatus

Abstract

A steam supply apparatus includes at least two pipes located in spaced apart, side by side relationship, and a cover member extending across the pipes and secured thereto. End members are secured to the respective opposite ends of the pipes, and a pair of baffles between each pair of pipes are secured thereto in a substantially V-shaped configuration with a slot between adjacent ends of the baffles at the base of the V-shape, the base of the V-shape being directed towards the cover member. Steam is supplied to the pipes, and each pipe has a series of apertures communicating the interior of the pipe with the space between the pipes, the cover member and the baffles.

       5. Apparatus according to claim 1 wherein a jacket member is secured in spaced relationship to the cover member, and insulating material is located in the space between the jacket member and the cover member. 
     
     
       6. Apparatus according to claim 5 wherein the jacket extends on the outer side of the outer pipes in spaced relationship thereto, with insulating material therebetween. 
     
     
       7. Apparatus according to claim 1 wherein the steam supply means includes a steam supply pipe connected to one end of one pipe, and a connector connecting the opposite end of said pipe to an adjacent pipe. 
     
     
       8. Apparatus according to claim 7 wherein the connector includes an adjustable valve to regulate the flow of steam from said one pipe to the adjacent pipe. 
     
     
       9. Apparatus according to claim 7 wherein at least three pipes are provided, and the connector includes separate adjustable valves to regulate the flow of steam from an inner pipe to outer pipes. .Iadd. 10. Steam supply apparatus comprising at least two pipes located in spaced apart, side by side relationship, a cover member extending between the pipes and extending longitudinally thereof and secured thereto, a bottom wall spaced below said cover member and extending longitudinally of and between and secured to the pipes, said pipes, cover member and bottom wall forming a steam chamber therebetween, end members closing said steam chamber near opposite ends of the pipes, steam outlet means in the bottom wall and extending substantially the length of the chamber between the pipes, and means for supplying steam to the pipes, each pipe having a plurality of apertures therein arranged longitudinally thereof and maintaining the interior of said steam pipe in communication with the steam chamber, and said pipes being adapted to extend across a surface against which steam is to be directed through said outlet means and to support the steam chamber above said surface. .Iaddend..Iadd. 11. Apparatus according to claim 10 in which said apertures in each pipe are located above the horizontal diameter thereof. .Iaddend..Iadd. 12. Apparatus according to claim 10 including stiffeners extending across the steam chamber and secured to the pipes, the cover member and the bottom wall, said stiffeners being spaced apart and dividing the chamber into sections. .Iaddend. .Iadd. 13. Apparatus according to claim 12 including opening means in said stiffeners maintaining said chamber sections in communication with each other. .Iaddend..Iadd. 14. Apparatus according to claim 10 in which said steam supplying means comprises an inlet pipe connected to one end of one of said pipes, and a connector pipe interconnecting an opposite end of one of said pipes to an adjacent end of the other of said pipes. .Iaddend..Iadd. 15. Apparatus according to claim 10 comprising a third pipe spaced laterally from an adjacent one of said first-mentioned pipes, a second cover member and a second bottom wall spaced from each other and secured to and extending longitudinally of said third pipe and said adjacent pipe and forming a second steam chamber therebetween, end members closing said second chamber near opposite ends of the pipes, steam outlet means in said second bottom wall and extending substantially the length of the second chamber, and means for supplying steam to the third pipe, said adjacent pipe and said third pipe having a plurality of apertures therein arranged longitudinally thereof and maintaining the interiors of said adjacent and third pipes in communication with the second steam chamber, and said adjacent and third pipes being adapted to support the second steam chamber above said surface. .Iaddend..Iadd. 16. Apparatus according to claim 15 in which said apertures of each of said pipes are located above the horizontal diameter thereof. .Iaddend..Iadd. 17. Apparatus according to claim 15 including stiffeners extending across each of said steam chambers and secured to the adjacent pipes, cover members and bottom walls, said stiffeners being spaced apart and dividing the chambers into sections. .Iaddend. .Iadd. 18. Apparatus according to claim 17 including opening means in said stiffeners maintaining said chamber sections in communication with each other. .Iaddend..Iadd. 19. Apparatus according to claim 15 in which said steam supplying means comprises an inlet pipe connected to one end of said adjacent pipe, and connector pipe means interconnecting an opposite end of said adjacent pipe to adjacent ends of the other of said pipes. .Iaddend..Iadd. 20. Apparatus according to claim 19 including valve means in said connector pipe means between said adjacent pipe and each of said other of said pipes. .Iaddend.
