【発明の詳細な説明】
本発明は、安定性と流動性がすぐれた微粉炭−油混合物
用添加剤(以下rCOMJという)を製造するための添
加剤に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an additive for producing an additive for pulverized coal-oil mixtures (hereinafter referred to as rCOMJ) having excellent stability and fluidity.
従来、微粉炭は発熱量当りの価格が安いのにもかかわら
ず、輸送の困難性、燃焼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等の欠点を有して
おり、燃料としては問題があった。COMは上記欠点が
なく、油単独の場合に較べて発熱量当りの価格が低いた
め、実用価4trが高い。しかし、微粉炭と油とを中に
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。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 the fuel. COM does not have the above drawbacks and has a lower price per calorific value than oil alone, so its practical value of 4 tr is high. However, if pulverized coal and oil are simply mixed together, the pulverized coal particles will settle and separate due to the difference in specific gravity.
凝結して流動性を失うため満足なCOMは得られない。Satisfactory COM cannot be obtained because it condenses and loses fluidity.
そこで、本発明名らは、長期間安定性と流動性を保持し

とする微粉炭−油混合物用添加剤である。Therefore, the inventors of the present invention have continued intensive research into additives that can maintain long-term stability and fluidity and adjust more economical COM, and as a result, have come to provide the present invention. It is something. That is, the main component is a compound obtained by reacting a portion or all of the terminal hydroxyl groups of a polyether compound with a molecular weight of 1,000 to 100,000, preferably 3,000 to 100,000, with an epoxy group-containing compound. This is an additive for pulverized coal-oil mixtures characterized by:

0〜60重量%がさらに好ましい。Such coal is put into oil as it is or after being crushed,
It may be directly pulverized in oil using various wet pulverizers, or it may be made into pulverized coal using a conventional dry pulverizer. However, wet pulverization υ: is even better because it improves the stability of COH and prevents spontaneous combustion and dust during pulverization. Moisture in the coal may be removed during dry pulverization, or may be removed during or after wet pulverization, and there is no problem even if coal containing only a small amount of moisture is not removed. The particle size of pulverized coal is usually preferably 200 microns or less in average particle size judging from combustibility, and even smaller particle sizes of 100 microns or less are preferred, but as far as physical properties such as COH stability are concerned, it is preferable to There is no problem even if it is large. The content of this fine powder is 20 to 70% by weight based on the final mixture, and if it contains more than 70% of pulverized coal, the viscosity will increase and fluidity will be lost, which is undesirable. The following cases are not preferable because the economic advantages associated with the inclusion of pulverized coal are reduced. Therefore, it can be contained in 20 to 70%, but 3
More preferably 0 to 60% by weight.

Waste oil from oil tankers and other ships, − grade chemical factory waste oil, etc., and also includes mixtures of these. Alternatively, COM may be adjusted using pre-blended oil, or CON may be prepared using a single oil (preferably petroleum crude oil or heavy oil) and then mixed or co-fired with oil.

There are cases where the manufacturer or user adds water, but transportation costs, storage costs, and other general and administrative costs will increase depending on the volume of water.
Furthermore, it is undesirable that the heat of evaporation during combustion is lost and the loss of heat IO becomes large, so the smaller the amount, the better.

Normal pressure, reduced pressure deaeration, etc. may be used, and the stirrer and stirring conditions are as follows:
No commitment is made unless the action of the additive is inhibited, but
In particular, strong stirring at a circumferential speed of 2 m/sec or more is preferred.

必要もない。By using the additive of the present invention, a COW with significantly improved stability and fluidity than before can be obtained, and it can be used not only at room temperature but also at room temperature.
Even when stored at high temperatures for long periods of time, there is almost no pulverized sedimentation, and even if a small amount of sedimentation occurs, due to the excellent action of the additives of the present invention, there is almost no agglomeration of the settled pulverized coal, so it can be easily stirred. It can be reflowed only with water. Of course, stirring is not necessary for a short period of time (about 15 stitches).

るまでの部間を測定し、この吟間を棒貫入時間とした。Next, the present invention will be explained in more detail with reference to Examples. In the examples, "%" is based on the electric resistance welding standard. The rod penetration test shown in the examples was conducted as follows. The test device used is a stainless steel cylinder with an inner diameter of 5.5 mm and a height of 20 cm, which has an outlet with a stopper at the bottom, 6 cm from the bottom, and 12 cm from the bottom. Fill this cylinder with the specified mixed fuel to a height of 18 cm from the bottom, cover the top of the cylinder with a lid with a guide hole in the center, and pass a smooth glass forest with a diameter of 5 cm at the tip (all sides) through the center guide hole. (20 g) was dropped vertically, and the distance from when the tip entered the mixed fuel until it reached the bottom of the cylinder was measured, and this distance was taken as the rod penetration time.
この吟間が短かい程微粉炭の沈降圧密が少なく、流動性

した。After the test, the 12 cm stopper was removed from the bottom, and the mixed fuel above it (i.e., the mixed fuel in the cylinder 12 to 18 cm from the bottom) was taken out and used as an upper layer sample, and its viscosity and coal concentration were measured. . Next, the stopcock at the 6CI11 position was removed from the bottom, and the mixed fuel above it was sampled, and its viscosity and coal concentration were measured as a middle layer sample. Finally, the bottom stopper was removed, the remaining mixed fuel was collected, and its viscosity and coal concentration were measured as a lower layer sample.
