Detailed introduction

The working principle of the top-charging coke oven machinery is that the coal is charged into the charging car on the oven top via the coal tower above the oven top and then the charging car sends the coal into the oven for coking. The equipment includes the pushing machine, charging car, guiding car, locomotive car, quenching car, hydraulic reversing machine, oven door service car, etc. The top-charging coke oven machinery developed and manufactured by DHHI is classified by the full height of the oven, including that for ovens of 4.3m, 5m, 6m, 6.25m, 7m, 7.2m, 7.63m and 8m.


The working principle of the stamping coke oven machinery is that the coal is charged into the charging car on the machine side via the coal tower on the ground of the machine side and meanwhile the coal is stamped into cake with a certain degree of strength by the stamping machine, then the charging car sends the cake into the oven for coking. The equipment includes the pushing machine, charging car, guiding car, locomotive car, quenching car, hydraulic reversing machine, oven top U-tube smoke guide car, stamping machine, shaking feeder, etc. The stamping coke oven machinery developed and manufactured by DHHI is classified by the full height of the oven, including that for ovens of 4.3m, 5.5m, 6m, 6.25m, 7.5m.


The heat recovery equipment consists of several sets of furnaces, which achieves cogeneration of coke and power in the process of coking. The working principle is that the hot gas produced in coking is recovered under negative pressure and is then sent to the exhaust-heat boiler for heat exchange; in this process, the superheated steam generated enters the steam turbine to make the blades rotate thereby driving the generator to work. The heat recovery equipment developed and manufactured by DHHI includes coal-charging & coke-pushing machine, coke receiving & quenching car, ground stamping station.


Coke bucket lifter, i.e. coke bucket crane, is the special lifting equipment in dry-quenching system. The coke bucket lifter developed and manufactured by DHHI is of new motion-control principle, which is characterized by high degree of “standardization, universalization and serialization”, high interchangeability of spare parts, realtime monitoring, safety and reliability, covering 63t-132t full series.
