It would still only be a fraction of the size, however, of the Cullinan diamond discovered in 1905, which was 3,106 carats when recovered and yielded a teardrop shaped diamond of 530 carats and is known as the Great Star of Africa.

然而,它的大小可能还只占一九O五年发现的库利南钻石的一小部分,当时发现的原石有三千一百零六克拉,后来切割琢磨出一颗五百三十克拉的泪滴型钻石,被称为「非洲之星」。

Consequently the diathermancy was strengthened, the effect of heat transfer was improved and the flow and combustion process in the boiler has become much better. First, in this thesis the burn characteristic of the rubbish and the process of combustion in the chain boiler has been studied. A series of mathematic model has been given. This thesis carefully introduced the principle and formula of the turbulent flow model、two-equation model、radiation model、dispersed phase model and standard wall function method. The software FLUENT has been applied to simulate the temperature、pressure、velocity and mass fraction of species in the boiler furnace and stokehole. The analysis and the comparison have been done. The calculation results indicate agreement with the fact and the studies both here and abroad.

首先,本文针对SZL10-1.25-MJ造纸垃圾焚烧锅炉,结合其燃料的特性,对垃圾的燃烧特性以及层燃炉中垃圾的焚烧过程进行分析;给出一套完整的垃圾锅炉炉内传热数学模型,并分别详细阐述了湍流流动模型、双方程模型、辐射传热模型、离散相模型及标准壁面函数的原理及计算公式;借助于Fluent软件平台对炉膛内的温度场、速度场、组分浓度场及炉膛出口的温度分布、速度分布、组分浓度分布等进行数值模拟,分别从定性和定量的角度与实际情况进行了比较,得到了较满意的结果;模拟结果与国内外的很多研究能较好符合。
