Technology overview

1. System overview
The Coal Cartridge System (CCS) collectively imports andmanufacture/supply and combustion bases, in an attempt toblends imported coal on behalf of medium-/small-lot consumers

As a result, the firstdifficult to directly import. Through CCS, the imported coal isJapanese CCS center, with a capacity to produce 200 thousand

eliminates the problem of the dispersion of coal dust, but alsoenables smoother operation through easier control of powder flows
and, therefore, fluctuations in boiler loads. CCS provides several

since the coal can now be stored in a silo. It also reduces capital
investments because of the compact equipment configuration, thus
leading to labor savings, as well as a better environment. CCS is, asmentioned above, a pulverized coal utilization system featuring
improved coal handling and a sealed-carriage system.
