The control principle of standing wind-drive device is proposed in this paper based on expatiating patent technology of standing wind-power generator.

The paper describes the technique of building refractory lining of sending-wind device in the 2# 2500 m3 BF constrcation.

was affected due to blockage of blow down device of 1600/600 blow down valve for cold air,Based on analysis and investigation,technical transformation was made on the piston ring, piston and shaft sleeve.

Design for new-style and hot-water car heater and research on its heat transfer performance;

Based on the widely available computational fluid dyna-mics(CFD) commercial code Fluent,the present work attempts to provide an insight into the ventilation perfor-mance of a generic square-section wind catcher system.
