A. 固體生物質燃料檢驗方法的標准
固體生物質顆粒燃料(BiomassMouldingFuel,簡稱"BMF"),是將秸稈、稻草、 稻殼 、 花生殼 、 玉米芯 、油茶殼、 棉籽殼 等「三剩物」作為原材料,經過粉碎、混合、擠壓、烘乾等工藝,製成各種成型(如塊狀、顆粒狀等)的,可直接燃燒的一種新型清潔燃料。其與煤性質相同,是可供各種燃燒機、生物質鍋爐、熔解爐、生物質發電等的高效、可再生、環保生物質燃料,此種燃料在國際認證為零污染燃料。生物質顆粒的直徑一般為6~10毫米,干基含水量小於10%~15%。
目前市場上生物質顆粒燃料種類很多,但大體上可分為三種:第一:農作物廢棄物:主要由秸稈、花生殼、稻草桿;第二:經濟作物廢棄物:主要由牲畜糞便;第三:林業廢棄物廢木、樹皮、裁剪掉的樹枝等。
對於生物質燃料而言,水分含量對其本身的熱值及燃燒所能獲得的能量有重要的影響。水分含量越高,相對的熱值就越低,同時,水分蒸發是一個吸熱過程,水分含量越高,蒸發所需要的能量就越高,燃料燃燒釋放出來的能量相對越低。
MS-590在線生物質顆粒燃料水分測定儀,是一款德國進口非接觸式多頻譜微波水分、密度測量儀,採用當今全球最新的多頻譜硬體技術和獨特模糊數據分析的專利演算法結合數據模型結構,可實現含水率與密度完全獨立測量,互不影響,適用於為固體生物質顆粒燃料中水分含量的實時在線測定,既可以皮帶上測定,也可以整包測定。
據德國默斯技術人員介紹,MS-590在線生物質顆粒燃料水分測定儀,可以在皮帶上測量全部生物質原料的水分,完全穿透測量。可以測量所有物料的實時水分和平均水分,不同於抽樣測量和離線測量。這是一款不受皮帶上的物料高度、密度、溫度、顏色影響的在線生物質水分測定儀,可以同時測量水分和密度兩個參數。該水分測定儀,不僅高可靠性:無任何可動部件和易損件,最高可達10年使用壽命,而且高精度:最高精度0.2%;寬量程比:水分測量范圍寬至0%-100%。同時,該水分測定儀適用范圍廣:一款儀器可測量幾乎所有類型的原料;內置校準曲線,一次校準成功後,無需經常校準。安裝簡易:可安裝在皮帶上、料倉內、斗內、管道上等各種位置。
B. 怎樣識別木炭質量優劣
木炭質量有很多理化指標,比如含水率 ,揮發分率,灰分率,含碳量 ,發熱量等等,不過一般家庭使用時,僅從外觀上鑒別就可以了。好的木炭質地緊密,有金屬光澤,重量較重,兩塊木炭互相敲擊時能發出清脆的聲音,符合這幾個條件,就是比較好的木炭了。
C. 木炭怎麼樣測含水量。俗稱黑炭。土窯燒出來的那種,,怎麼樣能測量出含水量
最簡單的方式,你可以先稱重,之後採用烘箱103±5℃烘乾,每隔2小時測量一下一下重量,直到兩次重量之差小於0.5g,即為絕干。含水率=(原重-乾重)/原重*100%。
除此之外,還可以用含水率測定儀測量,但會有誤差。上面的方法比較准確。

7. Checking regulation
7.1 Batch and Group Regulation and Sample Method
7.1.1 Batch and Group Regulation
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. 根據gb/t50123-1999的規定 採用什麼方法測定含水率時直接測定其含水率
國標法是用乾燥箱測試,速度慢,沒有5個小時出不來准確結果,你說的這一種是快速方法,如SFY-20B鹵素快速水分測定儀,採用國標乾燥失重法原理,結果准確,2-3分鍾出結果
F. 木炭檢測方法
你好,一樣檢測的!
都是檢測灰分,水分,熱量等。
G. 活性炭吸附水份多少計算公式
計算需要稱量多次,不如冠亞SFY-20T活性炭水分快速測定儀檢測方便,
這個可以快速檢測,活性炭吸水前後的含水率,只要3~5分鍾,快速方便、直接乾燥法,直接檢測就可以了
H. 煤炭的水分含量需要化驗嗎
化驗全水分
采過來的煤第一步需要做水分,也就是煤的全水。
所需器皿:大稱量瓶 電子天平 乾燥箱化驗方法和公式如下:
先將乾燥箱打開,將溫度升到145度,在天平上將稱量瓶稱出,記下皮重。再稱出10-12克煤記下煤重。在乾燥箱里烘30分鍾,取出後蓋上蓋子晾涼,在天平上稱出重量。公式如下:
皮重+煤重-烘過後重量
