Abstract
The invention relates to heat exchange devices for cooling the wall and the refractory of a blast-furnace. Such a device comprises a body shaped substantially as a body of revolution and having first and second end walls and a curved wall extending therebetween, the first end wall being a heat-transfer wall, a supply port and a discharge port for heat-transfer fluid, the ports being spaced-apart radially, the supply port being adapted for tangentially supplying the heat-transfer fluid into the body and the discharge port being adapted for tangentially discharging the heat-transfer fluid from the body, so that, in use, the fluid flows between the ports in a spiral path over the inner surface of the first end wall, the body having no internal obstacle to such flow. (FIG. 1)
Claims17
A heat exchanger comprising:
- a body having an inner chamber for the circulation of heat-transfer fluid, said chamber being shaped substantially as a chamber of revolution defined by first and second end walls and a curved peripheral wall extending therebetween, said first and second end walls being spaced from one another such that said chamber is substantially flat in shape, at least the first end wall being a heat-transfer wall;
- a supply port and a discharge port for the heat-transfer fluid, the ports being spaced-apart radially, the supply port being arranged and positioned to supply the heat-transfer fluid tangentially into the chamber and the discharge port being arranged and positioned to discharge the heat-transfer fluid tangentially from the chamber, so that, in use, the fluid flows between the ports in a spiral path over the inner surface of the first end wall, the chamber being free of internal obstacles to such flow.
