Carry out the moulded coal raw material of low-order coal process for upgrading.
Background technique
Coal is the main energy sources in China, and 70% is accounted for about in primary energy structure.During very long geological changes,
The formation of coal is caused categories of coal various by the effect of many factors.According to the difference of structure and composition, coal is divided into brown
3 major class of coal, bituminous coal and anthracite, metabituminous coal is divided into lower-grade metamorphic bituminous and mesometamorphism bituminous coal again, lower-grade metamorphic bituminous to be called time cigarette
Coal is referred to as " low-order coal " together with lignite.Low-order coal is the product at incoalation initial stage, with phosphorus content is low, moisture is high, easy
The characteristics of dusting, easy spontaneous combustion, fugitive constituent height, immersion intensity difference, anti-dropping intensity difference, these characteristics are limited to the direct of low-order coal
Development and utilization, but according to statistics, China's low order coal reserves account for the whole nation and have verified 55% of coal reserves or more, up to 561,200,000,000 tons, this nothing
It doubts and causes a kind of waste of resource.And with domestic energy demand increasingly increase and high-quality coal stock number falls sharply,
The conversion comprehensive utilization of low-order coal becomes people's increasingly focus of attention.
