泥炭又称泥煤、草炭,是在成煤初始阶段,未完全分解的植物残体在沼泽中形成的产物。被复盖了的泥炭由于地壳运动,经受成岩作用,失水、压紧而成为褐煤。风化煤是煤在矿床中或堆放时,受空气中、地下水中氧的作用,物理化学和工艺性质发生了变化,产生了可溶于碱的腐植酸类物质。根据现有资料,我国泥炭储量有270亿吨,褐煤841亿吨,烟煤无烟煤6000亿吨,其中风化煤仅山西省有70亿吨,由于水分,灰分一般都比较高,质量变化大,又称低热值燃料,或叫地区性燃料。自从1974年试验推广腐植酸类肥料以来,这些资源已逐渐引起人们的注意,并且积累了一些经验,也有不少教训,现结
Peat, also known as peat, peat is the initial stage of coal formation, incomplete decomposition of plant residues formed in the marsh product. The peat was covered by the crust movement, through diagenesis, water loss, compression and become lignite. Weathered coal is coal in the deposit or deposit, by the air, groundwater in the role of oxygen, physical and chemical properties have changed, resulting in alkali-soluble humic substances. According to the available information, there are 27 billion tons of peat reserves in our country, 84.1 billion tons of lignite and 600 billion tons of bituminous coal anthracite, of which weathered coal only has 7 billion tons in Shanxi Province. Due to the relatively high moisture and ash content, Low-calorie fuel, or regional fuel. Since the introduction of humic acid fertilizer in 1974, these resources have gradually attracted people’s attention and have accumulated some experience and many lessons.
