Abstract

The traditional biscuit firing process typically uses LPG, firewood, or electricity as a heat source. This research explores the application of a cross-draft biomass gasifier to generate and combust synthesis gas from rubberwood scraps as a heat source for small ceramic kilns. The firing program consists of two stages. In the first stage, rubberwood scraps are burned with primary air in the gasifier, causing the equivalence ratio (ER) to decrease from 2.07 to 1.36. During this stage, the kiln's internal temperature rises from room temperature to 400 °C. In the second stage, synthesis gas from the gasifier is burned at the burner with secondary air, reducing the ER from 1.68 to 1.18 and increasing the kiln temperature from 400 °C to 800 °C. Gas emission analysis showed that carbon monoxide (CO) remained below 690 ppm, while nitrogen oxides (NOx) peaked at 225 ppm at kiln temperatures above 400 °C. The final biscuit product exhibited a shrinkage of 2.69 %, a density of 1.71 g/mL, and a water absorption rate of 18.51 %.

交叉通风生物质气化炉和合成气燃烧器作为小型陶瓷窑热源的性能分析

传统的饼干烧制过程通常使用液化石油气、柴火或电作为热源。本研究探索了交叉通风生物质气化炉的应用，将橡胶木废料作为小型陶瓷窑的热源产生和燃烧合成气。发射程序包括两个阶段。在第一阶段，橡胶木屑与一次空气在气化炉中燃烧，使等效比（ER）从2.07下降到1.36。在这一阶段，窑内温度从室温上升到400℃。在第二阶段，由气化炉产生的合成气与二次风在燃烧器上燃烧，将ER从1.68降低到1.18，将窑温从400℃提高到800℃。气体排放分析表明，一氧化碳（CO）保持在690 ppm以下，而氮氧化物（NOx）在窑温高于400℃时达到峰值225 ppm。最终产品收缩率为2.69%，密度为1.71 g/mL，吸水率为18.51%。

期刊介绍： Case Studies in Thermal Engineering provides a forum for the rapid publication of short, structured Case Studies in Thermal Engineering and related Short Communications. It provides an essential compendium of case studies for researchers and practitioners in the field of thermal engineering and others who are interested in aspects of thermal engineering cases that could affect other engineering processes. The journal not only publishes new and novel case studies, but also provides a forum for the publication of high quality descriptions of classic thermal engineering problems. The scope of the journal includes case studies of thermal engineering problems in components, devices and systems using existing experimental and numerical techniques in the areas of mechanical, aerospace, chemical, medical, thermal management for electronics, heat exchangers, regeneration, solar thermal energy, thermal storage, building energy conservation, and power generation. Case studies of thermal problems in other areas will also be considered.
