As a result, the petroleum coke which is left in refining process of crude oil, Efforts are being sought to use.

Petroleum coke has a high calorific value and is cheaper than coal, but it is environmentally unfavorable to use as fuel because of its high sulfur content.

In addition, in the case of petroleum coke, the combustion furnace is required for the additional heat storage above the ignition temperature, since the combustion is not performed without the external heat source, and the combustion furnace structure capable of storing heat of 1,000 ° C or more is required.

At present, petroleum coke used in petroleum coke pulverized coal boiler used in Korea has an ash content of less than 1%, and when the ash content is high, it interferes with long-term operation and causes clinker .

Particularly, since a combustion furnace for pulverized coal petroleum coke produced in Korea has a structure in which ashes and unburned matters generated during combustion are not easily discharged, ash and unburned materials after the combustion reaction are deposited on the bottom of the combustion furnace, So that the combustion efficiency is lowered.

In the case of the conventional pulverized coal petroleum coke combustion furnace, there is a problem that the upper and the side of the bottom of the combustion furnace are treated with water pipes and refractories only, and the bottom portion is composed of only refractory materials, have.
