本文报导船用低速柴油机燃用流化催化裂化渣油和减粘裂化渣油的燃烧和磨损。文中所列数据是关于;柴油机的性能;燃烧室的燃烧特性;气缸套和活塞环的平均磨损率,燃烧室沉积灰中催化金属粒子的重量和大小。根据这些试验结果,我们认为,燃用流化催化裂化渣油时,由于残留在燃气中的硅粒子混入气缸套和活塞环的滑动表面之间,使磨损(磨料磨损)率增大。
This paper reports the combustion and wear of a marine low speed diesel engine using fluidized catalytic cracked residue and visbroken residue. The data presented are for diesel engine performance, combustion characteristics of the combustion chamber, average wear rates for the cylinder liner and piston rings, and the weight and size of catalytic metal particles in the deposition ash of the combustion chamber. Based on these test results, we believe that the rate of wear (abrasive wear) increases when fluidized catalytic cracking residuum is burned because the silicon particles remaining in the gas mix in between the sliding surfaces of the cylinder liner and the piston ring.
