fuel grade
2.Citing official records, Mr Langewiesche says that criminal markets have never produced sufficient weapons-grade fuel to make a bomb.
3.Abstract: This paper poited out that in the market compete conditions,the operation cost must be decreased, firstly , the sintering raw material and fuel constructions must be optimized, and then, the technical content must be increased, saving energy consumption, and producing high grade and high basicity sinter.
4.During a period from August 23 to September 22,1993 a monthly average productivity ratio of 2.96t/(m3·d) and a fuel ratio of 157kg/tHM were reached on No2 BF at Lules,Sweden,These good successes have been achieved owing to beneficiated burden material,high grade ( 67%) pellet,low ash (8.1 %) coke,advanced detection intsrument and blast furnace operation computer control.
