摘要: 由于工艺、设备、投料等变化,焚烧灰存在不完全燃烧现象,因而不满足后续处理要求,存在安全隐患。通过使用微波灰化炉对不完全燃烧焚烧灰以及较完全燃烧焚烧灰进行加热,对加热前后焚烧灰进行减重量、减重率及组分等一系列测试,研究微波加热对焚烧灰处理的可行性以及作用原理,并初步探索微波处理的工艺条件。结果表明,微波加热处理焚烧灰具有可行性,可达到与传统马弗炉同样的效果。微波处理焚烧灰的性能与加热功率、加热时间和处理量有关。加热功率和加热时间决定了微波处理焚烧灰的效率,而处理量决定了微波处理焚烧灰的能力。

Abstract: Due to changes in process, equipment and feeding, there exists incomplete combustion phenomenon in the incineration ash, which does not meet the requirements of subsequent treatment and brings trouble in safety. By using microwave ashing furnace to heat the incomplete combustion ash and relatively completed combustion ash, a series of tests and characterizations of weight loss, weight loss rate and composition of incineration ash were carried out before and after heating. The feasibility and principle of microwave heating for incineration ash were studied, and the process conditions of microwave treatment were preliminarily explored. The results show that it was feasible for incineration ash by microwave heating, which could achieve the same effect as the traditional muffle furnace. The performance of microwave treatment of incineration ash was related to heating power, heating time and treatment capacity. The heating power and heating time determined the efficiency of microwave treatment of incineration ash, and the processing capacity determined the ability of microwave treatment of incineration ash. The treatment efficiency was preliminarily explored. For incineration ash with particle size under 1 mm, the treatment efficiency was roughly the same when the power was enough.

Key words: incineration ash, incomplete combustion, microwave heating, treatment efficiency
