木炭含水率国标检测方法

A. 固体生物质燃料检验方法的标准

固体生物质颗粒燃料（BiomassMouldingFuel，简称"BMF"），是将秸秆、稻草、 稻壳 、 花生壳 、 玉米芯 、油茶壳、 棉籽壳 等“三剩物”作为原材料，经过粉碎、混合、挤压、烘干等工艺，制成各种成型（如块状、颗粒状等）的，可直接燃烧的一种新型清洁燃料。其与煤性质相同，是可供各种燃烧机、生物质锅炉、熔解炉、生物质发电等的高效、可再生、环保生物质燃料，此种燃料在国际认证为零污染燃料。生物质颗粒的直径一般为6~10毫米，干基含水量小于10%~15%。

目前市场上生物质颗粒燃料种类很多，但大体上可分为三种：第一：农作物废弃物：主要由秸秆、花生壳、稻草杆；第二：经济作物废弃物：主要由牲畜粪便；第三：林业废弃物废木、树皮、裁剪掉的树枝等。

对于生物质燃料而言，水分含量对其本身的热值及燃烧所能获得的能量有重要的影响。水分含量越高，相对的热值就越低，同时，水分蒸发是一个吸热过程，水分含量越高，蒸发所需要的能量就越高，燃料燃烧释放出来的能量相对越低。

MS-590在线生物质颗粒燃料水分测定仪，是一款德国进口非接触式多频谱微波水分、密度测量仪，采用当今全球最新的多频谱硬件技术和独特模糊数据分析的专利算法结合数据模型结构，可实现含水率与密度完全独立测量，互不影响，适用于为固体生物质颗粒燃料中水分含量的实时在线测定，既可以皮带上测定，也可以整包测定。

据德国默斯技术人员介绍，MS-590在线生物质颗粒燃料水分测定仪，可以在皮带上测量全部生物质原料的水分，完全穿透测量。可以测量所有物料的实时水分和平均水分，不同于抽样测量和离线测量。这是一款不受皮带上的物料高度、密度、温度、颜色影响的在线生物质水分测定仪，可以同时测量水分和密度两个参数。该水分测定仪，不仅高可靠性：无任何可动部件和易损件，最高可达10年使用寿命，而且高精度：最高精度0.2%；宽量程比：水分测量范围宽至0%-100%。同时，该水分测定仪适用范围广：一款仪器可测量几乎所有类型的原料；内置校准曲线，一次校准成功后，无需经常校准。安装简易：可安装在皮带上、料仓内、斗内、管道上等各种位置。

B. 怎样识别木炭质量优劣

木炭质量有很多理化指标，比如含水率 ，挥发分率，灰分率，含碳量 ，发热量等等，不过一般家庭使用时，仅从外观上鉴别就可以了。好的木炭质地紧密，有金属光泽，重量较重，两块木炭互相敲击时能发出清脆的声音，符合这几个条件，就是比较好的木炭了。

C. 木炭怎么样测含水量。俗称黑炭。土窑烧出来的那种，，怎么样能测量出含水量

最简单的方式，你可以先称重，之后采用烘箱103±5℃烘干，每隔2小时测量一下一下重量，直到两次重量之差小于0.5g，即为绝干。含水率=(原重-干重)/原重*100%。

除此之外，还可以用含水率测定仪测量，但会有误差。上面的方法比较准确。

The proct proced in one day or one shift is counted as a batch if the raw material and procere are basically consistent. Sampling must do in batch order.
7.1.2 Sampling Method
Take samples complying with total packages of each batch for packing procts. Sample randomly 3 from first 100 packages and subsequently take one from 100 (including less then 100). If being in bulk, 3% of proct amount should be sampled. More than 200 grams must be sampled for each batch at least. After mixing all samples, they then are separated into 4. Each is enclosed into a clean ground bottle and labeled. The contents of the label include the following: name, serial number, procer, type, batch number, grade, sampling date, and the person who sampled.
Four samples are used for inspecting appearance and dimensions, moisture, physical and chemical properties, and store for sparing respectively.
7.2 Inspection
It includes leaving mill and format inspection.
7.2.1 Leaving mill inspection
Each batch of proct must implement leaving mill inspection. This can either be executed by the quality control branch of a mill or by an authoritative inspection agency consigned by the mill. The inspection items should include appearance, moisture, dimension, net weight variation, and pH value at least because they are able to present major quality indexes correctly. The proct checked out will get a certificate and subsequently move into storehouse or leave mill.
7.2.2 Format Inspection
Format inspection must be implemented if the following situations occur (format inspection covers all items of this standard):
a) Resume proction after stopping for a long time.
b) Change raw material or major process, which might affect proct quality.
c) National quality and inspection organization put forward format inspection demand.
d) The situation of leaving mill inspection shows distinct variation comparing with last format inspection.
e) In normal proction, annual format inspection must be done at least
7.3 Determination Regulation
If one item in the inspection result does not meet the requirement of this standard, a double sample amount should be taken and re-inspected. If unqualified still, this batch of procts is estimated as a reject.
8. Symbol, Label, and Packing
8.1 Symbol and Label
The symbol or label of a proct must cover the following items: name and brand, type and specs, net weight, standard complied with, proction date, grade, name of company, procing area, company address, etc.
8.2 Packing
Proct packing should be firm, clean, moistureproof and the proct should be arranged tidily in the packing case. The packing material, specifications, net weight etc. of a batch of procts should be consistent. Packing can abide by the term of the agreement that has been made.

E. 根据gb/t50123-1999的规定 采用什么方法测定含水率时直接测定其含水率

国标法是用干燥箱测试，速度慢，没有5个小时出不来准确结果，你说的这一种是快速方法，如SFY-20B卤素快速水分测定仪，采用国标干燥失重法原理，结果准确，2-3分钟出结果

F. 木炭检测方法

你好，一样检测的！
都是检测灰分，水分，热量等。

G. 活性炭吸附水份多少计算公式

计算需要称量多次，不如冠亚SFY-20T活性炭水分快速测定仪检测方便，
这个可以快速检测，活性炭吸水前后的含水率，只要3~5分钟，快速方便、直接干燥法，直接检测就可以了

H. 煤炭的水分含量需要化验吗

化验全水分

采过来的煤第一步需要做水分，也就是煤的全水。

所需器皿：大称量瓶 电子天平 干燥箱化验方法和公式如下：

先将干燥箱打开，将温度升到145度，在天平上将称量瓶称出，记下皮重。再称出10-12克煤记下煤重。在干燥箱里烘30分钟，取出后盖上盖子晾凉，在天平上称出重量。公式如下：
皮重+煤重-烘过后重量
