针对传统陶瓷浆料复制聚氨酯泡沫工艺中存在的孔隙率难以精确控制和孔结构均匀性不足的问题，本工作引入一种基于规则六面体胞体结构的双斜方体设计方法，用于制备高性能多孔介质燃烧器用多孔陶瓷部件。通过精细调控一系列设计参数，如胞元体边长、孔筋直径以及阵列层数，探讨了这些参数对多孔陶瓷材料强度和燃烧特性的影响机制。结果表明，在低孔隙率（<90%）区域，通过增加孔筋直径降低孔隙率的方法，对多孔陶瓷材料强度和燃烧特性的影响更明显。在高孔隙率（≥90%）区域，通过减小胞元体边长和增加阵列层数降低孔隙率，其对多孔陶瓷材料的燃烧特性影响更为显著，当孔隙率降低3%时，燃烧时最高表面温度均降低50.0 ℃左右；发现孔筋直径降低孔隙率对多孔陶瓷材料的强度影响更为显著，当孔隙率降低约8%时，其耐压强度均可以提升1倍左右，在该区域，通过适当增加多孔陶瓷材料的孔筋直径（从1.4 mm增加到2.0 mm），可以使其耐压强度提升到0.60 MPa，而燃烧时最高表面温度仅降低12.7 ℃，CO排放仅增加11.26 mg/m³从而达到强度和燃烧特性的协同作用。

Introduction

To solve the problems that the porosity is difficult to accurately control and the pore structure uniformity is insufficient in the traditional process of replicating polyurethane foam with ceramic slurry, a biclinic body design method based on regular hexahedron cell structure was introduced to prepare porous ceramic parts for high-performance porous media burner. The influence of parameters (i.e., cell edge length, pore rib diameter and array layer number) on the strength and combustion characteristics of porous ceramic materials was investigated.

Methods

The model was firstly designed by a software named ANSYS Spaceclaim modeling, and then the samples were prepared by 3D printing. The compressive strength of porous ceramic structures was tested by a model TSE104B universal material testing machine at a loading rate of 0.5 mm/min. A circular loading plate with a diameter of 100 mm was used to apply pressure to the samples, and the maximum compressive strength σ_s of each sample was calculated by recording the failure load. Combustion performance testing was conducted in a porous media combustion platform, and the composition and temperature of the flue gas were monitored by a model testo 350 flue gas analyzer. The temperature changes were recorded by an infrared thermal imager.

The stress distribution and internal combustion mechanism of the porous ceramic under uniaxial compression were analyzed by numerical simulation methods. Among them, ANSYS Static Structural module was used for stress distribution analysis, and ANSYS Fluent module was used for finite element analysis of the flow field of porous media, thus evaluating the effect of porosity on gas disturbance, heat transfer behavior, fluid pressure drop, and heat exchange efficiency.

Results and discussion

In a high porosity range (i.e., ε≥90%), extending the residence time of premixed gas and enhancing turbulence effects can effectively promote gas mixing and combustion, thereby improving the overall combustion performance. Moderately reducing porosity (i.e., from 93% to 86%) improves the compressive strength of the material (approximately 100%) although this leads to a decrease in the maximum surface temperature (about 18.4 ℃) and an increase in CO emissions (about 8.75 mg/m³). This indicates that a moderate reduction in porosity sacrifices combustion efficiency at a high porosity can enhance the strength. In contrast, the structure in a low porosity range (ε<90%) restricts the free flow of gas flow, resulting in uneven velocity distribution and reduced turbulence, hindering effective gas mixing and combustion, thereby reducing combustion efficiency. This indicates that it is difficult to simultaneously improve combustion efficiency and strength at a low porosity. It is thus possible to balance combustion efficiency and strength via finely adjusting the porosity in the high porosity range (i.e., ε≥90%), achieving a synergistic effect.

Conclusions

The strength of SiC porous ceramic structures could be effectively improved via reducing the cell edge length a, increasing the number of layers n, and pore reinforcement diameter d. The pore reinforcement diameter d had a more significant impact on the strength of SiC porous ceramic structures. There was a certain enhancement effect on the maximum surface temperature of SiC porous ceramic structure via increasing a and decreasing n and d. At a high porosity, a and n had a more significant impact on the maximum surface temperature of SiC porous ceramic structure. At a low porosity, d had a more significant impact on CO emissions from SiC porous ceramic structures.
