  • Its clean DBM technology relies on a new type of kiln, which is a large, fully sealed, vertical model capable of producing 240 tpd DBM. It burns 248kg of coal per tonne of DBM produced, a reduction of 20% on conventional DBM kilns, and 99% of its solid waste is recyclable, according to [Robert Xie].

    Because the kilns are sealed, smoke and dust is almost entirely contained within the plant. The density of dust emitted from Fenghua Industries' kilns is less than 50mg/m3, while sulphur dioxide (SO2) and nitrogen oxide discharge densities are both less than 200mg/m3.

    Fenghua Industries' other new project to produce activated CCM via flash calcination, where fine magnesite particles are fed through a vertical kiln at high temperatures, yields three times more activated CCM than a traditional calcination kiln, according to the company.
