化されつつある。The benefits of coal as an energy alternative to petroleum are being reconsidered, and its use as a fuel is expanding. Coal heat generation:! 1
In order to compensate for this, fine coal powder and heavy oil are mixed together.
The use of slurry fuel (CiOM) has been studied and is being put into practical use.

、現状ではスラリーの粘度、貯留の際の安定性などの面
で、ｓｏ：ｓｏが実用上の限界とされている。In a slurry of coal and oil, it is desirable to have a large proportion of 5 coal due to the original purpose of replacing petroleum with coal, but currently, so:so is not suitable in terms of slurry viscosity and stability during storage. This is considered to be a practical limit.

う提案は未だなされていない。On the other hand, petroleum coke, which is a product of petroleum refining, is much smaller in quantity than coal, but it can be used for the same purposes as coal, especially bituminous coal, and has a lower ash content and calorific value than coal. It has the advantage that it requires less power when it is made into a fine powder because it has a high percentage characteristic and has good crushability.It has the advantage that it requires less power when it is made into a fine powder.It is possible to mix petroleum coke into a slurry of coal and oil, reduce the ash content of the slurry, and generate heat. Increasing the amount is being considered by some oil users, but no proposal has yet been made to improve the properties of slurry by taking advantage of the characteristics of petroleum coke in terms of friability.

特徴とするものである。In other words, the present invention takes advantage of the fact that petroleum coke is easier to pulverize than coal to produce a finer powder than coal.
Coal with a particle size of about 0 to 80%,
It is characterized by comprising a slurry consisting of petroleum coke and heavy oil.

うに添加丁ればよい。When adding petroleum coke to the slurry fuel for the purpose of reducing the ash content and increasing the calorific value, the coal and petroleum coke are crushed to about 70-80% of the 200 mesh pass, and the petroleum coke is added according to the required properties. However, when adding petroleum coke to improve the fluidity and stability of the coal-heavy oil slurry, the petroleum coke has a particle size smaller than that of the coal, preferably 500 mesh pass 70%. This finely pulverized coal is
It may be added in an amount of 20% by weight, preferably in the range of 2 to 10% by weight.
石油コークスは、石炭にくらべ微粉砕に必要とする動力
が少く、所要の粒径とするための機器も特殊なものを必
要としないという利点がある。Petroleum coke has the advantage that it requires less power to pulverize than coal, and does not require special equipment to obtain the desired particle size.

ークスのみケ所要の粒径とすればよい。If you want to simultaneously improve the fluidity and stability of the slurry, reduce the ash content, and increase the calorific value, the ratio of petroleum coke should be determined based on the latter condition, but the total amount of petroleum coke should be made with a particle size smaller than that of coal. There is no need to do this, and it is sufficient to use only the amount of petroleum coke necessary to improve the fluidity and stability of the slurry, that is, 1 to 20% by weight of coal, and the required particle size.
