Experimental study on velocity characteristic of engine fueled with petroleum coke slurry

Abstract

The new petroleum coke slurry fuel supply system was adopted in a R180 diesel engine, which was modified into the engine fueled with petroleum coke slurry. An investigation was carried out in the modified engine fueled with petroleum coke slurry. The engine fueled with 30 wt.% petroleum coke slurry could run steadily. The comparison test to velocity characteristic between engine fueled with 30 wt.% petroleum coke slurry and engine fueled with No. 0 diesel fuel was performed at full load running condition and at partial load running condition(75% load and 50% load). The test result showed that when burning petroleum coke slurry the specific fuel consumption was increased compared with that when burning diesel fuel. The brake torque and the brake power of the engine fueled with petroleum coke slurry were decreased compared with the engine fueled with diesel fuel, and the exhaust temperature of the engine fueled with petroleum coke slurry was similar to that of the engine fueled with diesel fuel.
