In the firing process of ceramic products, the sintering conditions vary from firing phase to firing phase. In different firing phases, flame texture changes obviously, so it can be used as a important parameter of burning zone identification for ceramic roller kiln. In this paper, both flame image recognition of simulating artificial-look-fire and multi-point temperature detection technology are used to detect burning zone working conditions of ceramic roller kiln so as to greatly improve detection accuracy. The key data fusion algorithm of PTCR-based point detection temperature and flame image recognition–based detection method of burning zone working condition for ceramic roller kiln are proposed. The temperature measurement experiment system scheme of ceramic roller kiln burning zone is also given. The system can fuse the key process data with flame image characteristics so as to get the comprehensive database used to judge burning zone working conditions and temperatures. In the end, The testing experiment was carried out. The experimental results show that the method proposed above is feasible and effective.

Consequent Effect

A combined experimental and numerical investigation into the thermal behaviour and its consequent effect on the performance of a three-lobe profile bore bearing is presented. Symmetric and tilted geometries are studied and the results show that loading direction has a significant effect on the thermal behaviour, but has little impact on the lubricant requirements and torque reactions in the bearing. The comparison between the numerical model and experiment shows very good correlation which supports the application of the numerical approach in the design role.

For the presence of high energy consumption and high emission in ceramic production, combining with the energy-saving and emission reduction targets of the National Twelfth Five-Year Plan, the advantages of oxygen-enriched combustion relative to normal combustion are analyzed. Concerning the new scheme of the internal burner distribution and new requirements made by combustion control method, the application of oxygen-enriched combustion technology in ceramic roller kiln is studied. The architecture and internal burner distribution scheme of ceramic roller kiln are improved in this study, and a novel combustion control method for oxygen-enriched combustion is used in the combustion experiment. Experimental results show that, with oxygen-enriched combustion, it can achieve complete combustion of the fuel, the flame characteristics conform the firing process requirements, and reduction of NOx emissions with proper O2 concentration.

The Relationship

The relationship between ceramic roller kiln simulation model building parameters and temperature field uniformity is extremely difficult work. In this paper, DEPSO-CFD, a system integrated of an algorithm of hybrid particle swarm (PSO) with Differential Evolution (DE) operator, termed DEPSO, and computational fluid dynamics (CFD), is proposed to meet the demand. And with the help of the efficient parallel calculation, the ceramic roller kiln temperature field uniformity is mainly researched by using Fluent and DEPSO algorithm. It proves that the system is of high speed and of excellent parameter exploration capability, and the final computational example is got; thus parallel-DEPSO-CFD is of great academic value and significant applicable value.
