• Erosion mechanism of non-uniform particles was quantitatively investigated.
• A new indicator of uneven factor was proposed.
• A preceding rotating sheet structure (PRSS) was innovatively designed.
• PRSS structure shows excellent corrosion resistance based on the simulation.
The elbow erosion seriously jeopardizes the safe and stable operation of water–slag discharge pipeline of the coal gasification system. This work simulated water–slag elbow characteristics with various slag injection positions by simulating five simplified and representative erosion categories, including A-type horizontal-vertical elbow with an upstream flow, B-type horizontal-vertical elbow with a downstream flow, C-type vertical-horizontal elbow with an upstream flow, D-type vertical-horizontal elbow with a downstream flow and E-type horizontal-horizontal elbow. Compared with the C/D-type elbow, where particles were injected uniformly, the A-type elbow and E-type elbow were found to increase erosion rate, while the B-type elbow decreases erosion rate. An interesting discovery is that the elbow erosion rate is relatively low for small particles when particles are injected from the middle and bottom positions of the inlet section of the elbow. Based on the observation, a novel preceding rotating sheet structure was developed to regulate the particle injection position. It shows an excellent anti-erosion performance by reducing the maximum erosion rate of particles with diameters of 50, 100, and 200 μm by 23%, 35%, and 43%, respectively.
