Recently, the heat-recovery coke oven machinery developed and manufactured by DHHI for IRNC was put into operation and achieved successful coke pushing. It is the first time for our company to develop and manufacture such type of coke oven machinery and also the first time for DHHI to export coke oven machinery toIndonesia. This symbolizes that DHHI has made one more solid step forward in the process of development and realization of commercialization of new product.

This heat-recovery coke oven that is put into operation is different from the traditional one in the aspects of coking process and oven body structure. The negative-pressure coking process and residual heat recovery system are used, which can realize self-sufficiency of electric power for the enterprise, reduce the environmental pollution and expand the resources of coking coal, and there’s great demand for such coke oven in the markets of Southeast Asia, India, Brazil, etc.
