【発明の詳細な説明】
本発明は、安定性と流動性が優れた微粉炭一油混合物を
製造するための、微粉炭一油混合物用添加剤に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an additive for a pulverized coal/oil mixture for producing a pulverized coal/oil mixture with excellent stability and fluidity.
従来、微粉炭は発熱量当たりの価格が安いにもかかわら
ず、輸送の困難性、燃暁に関しての制御の困難性、発熱
量の低さ、貯蔵に要する場所がかさむといった欠点を有
しており、燃料としては問題があった。Conventionally, although pulverized coal has a low price per calorific value, it has disadvantages such as difficulty in transportation, difficulty in controlling combustion, low calorific value, and large storage space. However, there was a problem with fuel.
微粉炭と油の混合物は上記欠点がなく、油単独の場合に
比べて発熱量当たりの価格が低いため実用価値が高い。A mixture of pulverized coal and oil does not have the above-mentioned drawbacks and has high practical value because it has a lower price per calorific value than oil alone.
しかし、微粉炭と油とを単に混合しただけでは、比重差
のため、微粉炭粒子は沈降分離し、凝結して流動性を失
うため満足な微粉炭一油混合物は得られない。However, simply mixing pulverized coal and oil does not result in a satisfactory pulverized coal-oil mixture because the pulverized coal particles settle and separate due to the difference in specific gravity, coagulate, and lose fluidity.
したがって、安定性と流動性とを向上する添加剤を見い
出すことが重要で、すでに、本発明者等は上記問題点を
克服し、有効な添加剤を見い出すことに成功し、微粉炭
一油混合物の実用化を可能にした。Therefore, it is important to find additives that improve stability and fluidity, and the present inventors have already succeeded in overcoming the above problems and finding effective additives. This made it possible to put it into practical use.
(特開昭53−78207)本発明者らは、更に長期間
安定性と流動性を保持し、かつ、より経済的な微粉炭一
油混合物を得るべく鋭意研究を続けた結果、後記する微
粉炭一泊混合物用添加剤を見い出す事に成功し、非常に
優れた微粉炭一油混合物の製造に成功した。(Japanese Patent Application Laid-Open No. 53-78207) As a result of our intensive research to obtain a more economical pulverized coal-oil mixture that maintains stability and fluidity for a longer period of time, we found that the pulverized coal and oil mixture described below We succeeded in discovering an additive for charcoal/oil mixtures and succeeded in producing a very superior pulverized coal/oil mixture.
本発明により、従来よりも著しく、安定性と流動性が向
上した微粉炭一油混合物が得られ、常温はもとより高温
において長期間保存しても、微粉炭の沈降は殆ど生ぜず
、たとえ若干生じても、本薬剤の優れた働きにより、沈
降した微粉炭の凝集がほとんど起こらないため、ご《簡
単な攪拌のみで再流動化することができる。According to the present invention, a pulverized coal-oil mixture with significantly improved stability and fluidity than before can be obtained, and even when stored for a long period of time at not only room temperature but also high temperature, pulverized coal will hardly settle, and even if it does occur slightly. However, due to the excellent action of this agent, there is almost no agglomeration of settled pulverized coal, so it can be re-fluidized with only simple stirring.
もちろん、短期間(15日程度)の場合は攪拌の必要も
ない。Of course, stirring is not necessary for a short period of time (about 15 days).
これにより、安心して微粉炭一泊混合物を長期間かけタ
ンカー輸送することや、タンクで貯蔵することや、パイ
プラインや配管を流送することも可能となった。This has made it possible to safely transport the pulverized coal overnight mixture in tankers over long periods of time, store it in tanks, and transport it through pipelines and piping.
また、本薬剤は、従来よりも使用量が少なくてすみ、経
済性の面からも微粉炭一油混合物の実用化を更に促進で
きた。In addition, the amount of this drug to be used is smaller than that of the conventional method, and from an economical point of view, it has further promoted the practical application of pulverized coal and oil mixtures.
微粉炭一油混合物に用いる石炭とは、例えば無煙炭、瀝
青炭、亜瀝青炭、褐炭等の各種石炭で、種類や産地にか
かわりなく、また化学組成や水分含有量にもかかわりな
《、いかなるものも利用できる。The coal used in the pulverized coal-oil mixture includes various types of coal, such as anthracite, bituminous coal, sub-bituminous coal, and lignite, regardless of its type, production area, chemical composition, or moisture content. can.
かかる石炭をそのままか、あるいは粗砕して油中に入れ
、各種湿式粉砕機により、油中で直接微粉炭とするか、
または通常の乾式粉砕機により微粉炭としてもよい。The coal is either left as it is, or coarsely crushed and placed in oil, and made into pulverized coal directly in oil using various wet crushers;
Alternatively, it may be made into pulverized coal using a conventional dry pulverizer.
ただし、湿式粉砕法の方が、微粉炭一油混合物の安定性
が向上し、かつ、粉砕時の自然発火や、粉じんが防止で
きるため更に良い。However, the wet pulverization method is better because it improves the stability of the pulverized coal-oil mixture and prevents spontaneous combustion and dust during pulverization.
石炭中の水分は、乾式粉砕時に除いても、あるいは湿式
粉砕中や粉砕後に除いてもよく、含有水分の少ないもの
は、除かなくても支障がない。Moisture in the coal may be removed during dry pulverization, or during or after wet pulverization, and if the coal contains a small amount of moisture, there is no problem even if it is not removed.
微粉炭の粒度は燃焼性より判断して、通常平均粒子径2
00μ以下のものが好ましく、更に粒度の小さい100
μ以下が好適であるが、微粉炭一泊混合物の安定性等の
物性に関するかぎり、更に粒度の大きいものでも問題は
ない。The particle size of pulverized coal is determined from combustibility, and is usually an average particle size of 2.
00μ or less is preferable, and even smaller particle size is 100μ.
It is preferable that the particle size is less than μ, but as far as the physical properties such as the stability of the overnight mixture of pulverized coal are concerned, there is no problem even if the particle size is larger.
この微粉炭の含有量は最終混合物に対して20〜70重
量%であり、70重量%以上の微粉炭を含有した場合は
、粘度が著しく高くなり、流動性を失うため好ましくな
く、20重量%以下の場合は微粉炭含有に伴う経済面の
利点が減少するため好まし《なる。The content of this pulverized coal is 20 to 70% by weight based on the final mixture. If the pulverized coal is contained in an amount of 70% by weight or more, the viscosity will become extremely high and fluidity will be lost, which is undesirable. The following cases are preferred because the economic advantages associated with the inclusion of pulverized coal are reduced.
したがって、20〜70重量%含有できるが30〜60
重量%が更に好ましい。Therefore, it can contain 20 to 70% by weight, but 30 to 60% by weight.
% by weight is more preferred.

む。In addition, the oil used in the pulverized coal-oil mixture includes petroleum crude oil, various fractions obtained from crude oil, such as kerosene, light oil, A heavy oil,
Oils and waste oils commonly used as fuel such as B heavy oil, C heavy oil, ethylene decomposition residual oil, creonate oil, anthracene oil, various blended oils, etc., such as gas station waste oil (automobile lubricating oil, cleaning oil) ironwork waste oil (machine oil) , cutting oil, cleaning oil, and mixtures thereof), waste oil from oil tankers and other ships, waste oil from general chemical factories, etc., and also includes mixtures of these oils.
中でも、石油原油、B重油およびC重油の利用が好まし
い。Among them, it is preferable to use petroleum crude oil, B heavy oil, and C heavy oil.
単独油のみ、または予め配合した油を用いて微粉炭一油
混合物を作っても、単独油(好ましくは石油原油、重油
)で、微粉炭一油混合物を作った後、他の油を混合した
り、混焼してもよい。Even if you make a pulverized coal-oil mixture using only a single oil or a pre-blended oil, you can make a pulverized coal-oil mixture using a single oil (preferably petroleum crude oil or heavy oil), and then mix other oils. or mixed firing.

が高《なり、更に燃料時蒸発熱をうぽい、熱損失が大き
くなるため好ましくなく、少ない方がよい。Water may be mixed into the pulverized coal overnight mixture, or added by the manufacturer or user. This is not preferable because it increases the heat of vaporization of the fuel and increases heat loss, so the lower the better.
一方水は、微粉炭一油混合物の安定性を良好にする性質
と、燃焼時排ガス中のNOx とバイジンを少なくする
効果を有するため少量の混入は許される。On the other hand, water is allowed to be mixed in a small amount because it has the property of improving the stability of the pulverized coal and oil mixture and has the effect of reducing NOx and byzine in the exhaust gas during combustion.
したがって、全水分量は9重量%以下、好ましくは6重
量%以下がよく、まったく含有しなくてもよい。Therefore, the total water content is preferably 9% by weight or less, preferably 6% by weight or less, and may not be contained at all.
ただし、0.5%〜3%程度の水を薬剤と共に後添加し
た場合、著しく安定性が向上する場合が多い。However, when about 0.5% to 3% of water is added later together with the drug, stability is often significantly improved.
