Petroleum-coke was fired only in CFB because of its content of high S and low volatile matter. It will bring environmental and flame stability problems if petroleum-coke is fired in a pulverized coal-fired furnace. Low rank anthracite is fired in many pulverized coal-fired furnaces without flame stability problems. Here the authors blend high ash anthracite with petroleum-coke as the fuel for a pulverized coal-fired furnace to decrease the ash content in the fuel. Experimental results had shown that in mixing with petroleum-coke, the combustion behavior of the blended fuel was 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 the environment and furnace. But S content in blended fuel must be controlled under the regulation of S content in coal and the volatile content should not decrease too low for the coal-fired furnace design to avoid the environmental and flame stability problems.
