Pyongyang, July 13 (KCNA) — Scientists of Kim Chaek University of Technology in the Democratic People’s Republic of Korea have succeeded in developing a new kind of material for electricity production at thermal power plants.
The cheap material is used for the rotating cylinders pulverizing fossil fuel to increase combustion rates in large boilers instead of expensive alloy steel.
With this material, each power plant can save tens of tons of alloy steel and a lot of bolts every year.
In particular, its application nearly doubles the serviceable span of the cylinder inner walls and remarkably raises the fineness of the pulverized fossil fuel.
