Each pyrite box is provided with 2 knife gate valves, at inlet and outlet flanges, to disconnect the mill (at positive pressure) from the downstream equipment (at atmospheric pressure). The rejects are intermittently extracted from the pyrite boxes by short MRS ® conveyors and dosed to the main MRS® conveyor, which receives the rejects produced by all 6 coal mills.

A novel suspension-floating-circulating fluidized …

 · A novel suspension-floating-circulating fluidized combustion technology is proposed for burning coal slurry fuel in traditional circulating fluidized bed boilers (CFBB). This technology can solve some existing problems in large-capacity CFBB burning coal slurry. The principles of the suspension-floating-circulating fluidized combustion technology were introduced in detail in this paper. A 130 ...
