Petroleum-coke was fired only in CFB because of its content of high S and low volatile. It will bring environment and flame stability problem if petroleum-coke fired in pulverized coal-fired furnace. As the research of coal fire theory has been developed in last decade, low rank anthracite is fired in many pulverized coals fired furnaces without flame stability problem. Here we blend high ash anthracite with petroleum-coke as the fuel for pulverized coal-fired furnace to decrease the ash content in fuel. Experiment result had shown that mixing with petroleum-coke the combustion behavior of blending fuel were improved and ash deposition characteristic would not change compared with high ash anthracite. Using coal/petroleum-coke as the fuel for furnace can bring great benefits for environment and furnace. But S content in blend fuel must be controlled under the regulation of S content in coal and the volatile content should not decrease too low to coal fired the furnace design to avoid the environment and flame stability problems occur.
