第三十节煤气车间
煤气厂的高架厂房下，浇铸好的钢筋水泥基座上矗立着十多座圆筒形的煤气发生炉，煤气发生炉使用水套密封，输煤气管道在高架厂房的铁支架上已经安装就位，输气管道是铸铁的，接口处用水玻璃混合瓷器碎末密封――这是目前他们最好的防腐蚀密封材料。龙腾小说ltxs520.com临高对瓷器粉的巨大的需求使得广东、福建两地兴起了新得行业：收购碎瓷片。窑厂在烧造过程中破碎、伤损的瓷器，过去是直接丢弃，现在有商人专门去收购之后打包运到临高来。工业部门再把碎瓷片用球磨机碾碎成细粉备用。
阀门和流量仪表是临高自产的，质量不是很有保证，因而整个厂房四周是全敞开式，以便最大程度的做好通风，避免发生泄露造成伤亡事故。
“什么问题？”姜野跳下车，先看了一眼挂在车间门口的鸟笼――他们没有可以向煤气内添加的特殊化学品来作为警告气味，所以只能在所有有煤气的地方用最简单的鸟类测试法。里面的小鸟看上去很活泼，没有什么特殊后的状态。
“4号炉的出口温度升得太快了！”带班的工长惊慌不安的说着递上了工作记录本。他从前是个烧窑工，有一手绝活，炉子里是多少温度他一看火的颜色就知道。不过自从到了临高之后，他的这手技术就被工业温度计取代了。尽管他的秘法不值钱了，但是他的工作经验还算有用，因而就培训他当了工长。他
姜野看了一眼工作记录本，透过观察窗看了下炉内的情况――其实他对煤气发生炉也不算了解，只不过突击学了不少这方面的技术。
“应该是偏运行了。”姜野说。所谓偏运行就是炉内灰层一边高，一边低，火层也同时偏斜，高的一边冒火呈热运行，低的一边发暗呈冷运行，“测试下发生气质量！”
炉内产生的煤气被引流一部分到支管的测试专用燃烧口上――他们没有测定气体含量的仪器，只好用最简单的燃烧目测的方式来粗粗检验气体中的几种主要成分。
“报告！一氧化碳含量下降了！二氧化碳含量增加！”一个在工地实习的学生大声报告着。
“拿炉杆来。上炉顶去捅灰！”姜野招呼一声，马上有人把专用的炉杆拿了过来，“你们几个，用钩子从灰盘拨灰，把灰渣弄出来！”
姜野先把累积起来的高灰层捅开，弄低。再配合下面的拨灰，灰渣被清理出来许多，即使用目光检视也可以看出灰中的碳含量偏高，这说明他的对故障的判断基本上是正确的。拨完了灰，他又关照工人用铁钎在料层燃烧猛烈的地方捣实紧密，又适当加入了一些料，使得料层保持均匀状态。
又过了一会，出气口的温度和出气质量都恢复到正常范围。故障算是排除了。姜野知道这算是煤气发生炉里最简单的故障了，不过也最常见。穿越集团使用煤气发生炉有相当的规模，但是有经验的人手紧缺这个难题始终没有解决。即使是钢铁厂这样的重要项目也得不到足够的熟练人手。
他看了看这群人，除了工长之外，没有一个人是有过操作煤气发生炉经验的，――培训工作还是任重道远。一遇到问题，工长自己也抓瞎了。
姜野先简单的分析了故障的原因，处置的方法和为什么要这么处置。这都是很简单的东西，只要有一个老师傅带着，很快就能带出一批熟练工来，但是现在的“老师傅”自己也不怎么靠谱。
解决故障是一方面，还得找出故障的原因。姜野从煤气发生炉的技术手册里知道发生偏运行的因素不多，除了炉内结焦之外就是炉料有问题。从刚才处置的状况看，炉内的结焦都被及时的处理了。
姜野捏了一把装在筐子里的煤颗粒――气化炉的燃料多种多样，这里用得是洗煤厂的洗煤之后的槽煤，也就是洗煤废水中沉淀下来的煤粉煤屑。经过收集晾干和碾磨处理。
煤末在手里的感觉似乎有些湿乎乎的，含水量过大。姜野在心里先给出了第一个原因。
