A TOP-COMBUSTION HOT BLAST STOVE

摘要

A top-combustion hot blast stove comprises a burner (4), a vault (2) and a furnace body (3), in which, the burner includes a gas distribution loop (5a), an air distribution loop (5b), a circumferential premixing passage (7) and several equalizing-choke flow devices, the gas distribution loop (5a) and the air distribution loop (5b) connect with the circumferential premixing passage (7) through respective nozzle (6a, 6b). The hot blast stove could increase combustion intensity, and homogenize the distribution of velocity and temperature.
