Coke oven machinery is applied in metallurgical engineering field and is the packaged equipment necessary for coking. DHHI has been engaged in design and manufacture of coke oven machinery since 1950s and has provided nearly 630 sets of coke over machineries for about 300 customers both at home and abroad. The products include top-charged and stamping coke over machineries (for coke ovens of 4.3m, 5m, 5.5m, 6m, 6.25m, 6.7m, 7m, 7.63m and 8m), environmental protection & dedusting equipment, heat recovery and automatic control equipment , for coke oven.

Top-charged Coke Oven Machinery

Depending on different coking processes used, coke oven machinery divides into two types, i.e. top-charged type and stamping type. Top-charged type means the coal is charged into the charging car located on the oven top via the coal tower above the oven top, and then the charging car feeds the coal into the chamber for coking. Top-charged coke oven machinery includes pushing machine, charging car, coke guiding machine, locomotive car, quenching car, hydraulic reversing machine, door service car, etc. The top-charged coke oven machinery developed and manufactured by DHHI is classified by overall height of the chamber as 4.3m, 5m, 6m, 6.25m, 7m, 7.2m, 7.63m and 8m.

Stamping Coke Oven Machinery

Depending on different coking processes used, coke oven machinery divides into two types, i.e. top-charged type and stamping type. Stamping type means the coal is charged into the charging car located on the machine side via the ground coal tower on the machine side, meanwhile the coal is tamped into cake with a certain strength by the stamping machine, and then the charging car sends the coal cake into the chamber for coking. Stamping-type coke oven machinery includes pushing machine, charging car, coke guiding machine, locomotive car, quenching car, hydraulic reversing machine, U-tube smoke guide car on the oven top, stamping machine, shaking feeder, etc. The stamping-type coke oven machinery developed and manufactured by DHHI is classified by overall height of the chamber as 4.3m, 5.5m, 6m, 6.25m and 7.5m.

Dedusting Equipment for Coke Oven

Fume and dust from coke oven is one of the sources for pollution of atmospheric environment. Great amount of dust, high temperature and wide pollution area during charging and pushing has become an important factor restricting the development of coke oven machinery. To eliminate the pollution in charging and pushing, DHHI developed a complete set of environmental protection system which is in the form of ground dedusting station, for the coke oven. This system can effectively control the pollution from charging and pushing to achieve the effects of both economy and environmental protection. It realizes an emission of 0.15 and is green, energy-saving and represents the current national emission standard.

Heat Recovery Coke Oven Machinery

The clean-type heat recovery coke oven includes several batteries and each battery consists of several ovens in cave dwelling shape. During coking, heat is recovered under negative pressure and is exchanged through the exhaust-heat boiler to generate the superheated steam which then drives the steam turbine generator to work to achieve the combined production of coke and electric power. The heat recovery equipment developed by DHHI includes SCP machine, coke receiving and quenching car and ground stamping station.
