炼焦用煤炼焦用煤coal for coke makinglianjiao yong mei炼焦用煤(eoa一for eoke making)在焦炉炼焦条件下,用于生产一定质量焦炭的原料煤。为保证焦炭质量,选择炼焦用煤的最基本要求是考察它的挥发分、粘结性(见煤的拈结性)和结焦性(见煤的结燕性),保证尽可能低的灰分、硫分和磷含量。因此,绝大部分炼焦用煤必须经过洗选。在选择炼焦用煤时,还必须考虑煤在炼焦过程中的膨胀压力。低挥发分的煤,因其胶质体粘度大,炼焦时容易产生高的膨胀压力,对焦炉砌体造成损害,这需要从配煤方面加以解决。此外,在焦化厂的生产成本中,炼焦用煤占很大比重,因此在选择炼焦用煤时,还必须考虑煤的价格和运输距离等经济因素。世界煤炭资源尚丰富,但炼焦用煤资源有限,故必须注意节约使用和扩大其范围。煤按其在炼焦过程中的性状,可分为炼焦煤和非炼焦煤。炼焦煤是指用单种煤炼焦时,可以生成具有一定块度和机械强度的焦炭的煤。这类煤具有粘结性,主要供炼焦用。烟煤中的气煤、肥煤、气肥煤、1/3演煤、焦煤和瘦煤都属于炼焦煤。炼焦煤中的焦煤可以单独炼焦,生产出符合要求的高炉焦。但是焦煤的资源从世界范围来说,都是匾乏的。因此,通常把两种或两种以上煤牌号的炼焦煤,以适当比例进行配煤,然后炼焦,以满足对焦炭质量的各种要求。非炼焦煤在单独炼焦时不软化、不熔融、不能生成块状焦炭。这类煤没有或仅有极弱的粘结性,一般不作为炼焦用煤。但当配煤中粘结组分过剩或需要生产特殊焦炭(如铸造焦)时,可以配入少量非炼焦煤,作为瘦化剂用。非炼焦煤也可以作为生产型煤或型焦的原料。(见型焦用料)揭煤、无烟煤以及烟煤中的长焰煤、不拈煤和贫煤,都属于非炼焦煤。为了扩大炼焦用煤资源,在中国煤炭分类国家标准中,还划分了一些过渡性煤种如贫瘦煤、1/2中拈煤和弱拈煤等。根据各地资源特点以及配煤和炼焦技术的发展水平,有的焦化厂可在配合煤中配入部分过渡煤。如在有一定量强肥煤的情况下,配用一些低灰低硫的弱粘煤,以降低焦炭的灰分和硫分。根据中国冶金系统主要焦化厂1990年的统计,炼焦用煤的煤种比例(%)为:瘦煤9.8,焦煤31.2,肥煤16.9,气煤25.9,1/3焦煤12.8,气肥煤1.7,其他煤1.7。研究和选择炼焦用煤的理论基础是煤化学和煤若学。它们研究煤的生成、煤的化学组成(见煤的分析、煤中矿物质)、煤的老相组成、煤的性质、煤炭分类、煤的化学结构和煤的成焦机理,揭示各种煤的本质和它们在炼焦中的作用,从而为合理选择炼焦用煤,保证焦炭质量提供依据。
