Abstract
A heat exchanger system suitable for iron making furnaces and their supporting exhaust and cooling systems. The heat exchange has at least one panel of sinuously winding piping having an inlet and an outlet, an input manifold in fluid communication with the inlet of the at least one panel, an output manifold in fluid communication with the outlet of the panel, a cooling fluid flowing through the piping, and a stream of hot exhaust gasses flowing over the piping. The heat exchanger system is preferably fabricated using an aluminum bronze alloy. The operational life of the heat exchanger is extended and corrosion and erosion of the heat exchanger and related components is reduced.
Claims54
A heat exchanger system, said system comprising:
- a furnace having means for heating an interior of the furnace and generating exhaust gases in the temperature range of about 4000° F. to 5000° F.;
- at least one heat exchange panel of sinuously winding piping having an inlet and an outlet;
- an input manifold in fluid communication with the inlet of the at least one panel;
- an output manifold in fluid communication with the outlet of the at least one panel;
- the piping being configured to have a cooling fluid flowing through the piping;
- the piping being located to have a stream of hot exhaust gasses from the furnace flowing over the piping;
- wherein the sinuously winding piping is substantially an assemblage of sectional lengths of connected tubes mounted side-by-side;
- and
- wherein the connected tubes are secured to each other with links therein forming the at least one panel, the links separating adjacent tubes so that there is a space between the adjacent tubes along at least a portion of the length of the adjacent tubes.
A heat exchanger system adapted for use with a furnace capable of producing exhaust gasses in the temperature range of about 4000° F. to 5000° F., said system comprising:
- at least one panel of sinuously winding piping having an inlet and an outlet, wherein the at least one panel is affixed to a base plate;
- an input manifold in fluid communication with the inlet of the at least one panel;
- an output manifold in fluid communication with the outlet of the at least one panel;
- the piping being configured to have a cooling fluid flowing through the piping;
- the piping being located to have a stream of hot exhaust gasses from the furnace flowing over the piping;
- wherein the sinuously winding piping is substantially an assemblage of sectional lengths of connected tubes mounted side-by-side;
- and
- wherein the connected tubes are secured to each other and to the base plate with links therein forming the at least one panel, the links separating adjacent tubes so that there is a space between the adjacent tubes along at least a portion of the length of the adjacent tubes.
A heat exchanger system, said system comprising:
- a furnace having means for heating an interior of the furnace and generating exhaust gases in the temperature range of about 4000° F. to 5000° F.;
- at least one heat exchange panel of a sinuously winding channel through a front plate and a base plate, the at least one panel having an inlet and an outlet;
- an input manifold in fluid communication with the inlet of the at least one panel;
- an output manifold in fluid communication with the outlet of the at least one panel;
- the piping being configured to have a cooling fluid flowing through the channel;
- the piping being located to have a stream of hot exhaust gasses from the furnace flowing over the front plate;
- and
- wherein the sinuously winding channel is substantially an assemblage of baffles mounted between the front plate and the base plate that route the cooling fluid.
