一、引言 作者基于蒙特卡罗法设计出的计算程序已用于国际火焰。研究基金会的两台试验炉(分别燃烧石油和天燃气)炉膛传热的计算,并获得十分满意的结果。本文改进了原模型以适用于工业规模的燃煤炉膛并对新南威尔士州Bayswater电站1~#炉进行模拟计算,并着重分析了模型结果对煤种输入变化的灵敏性。 二、数值模型 1.计算区域的划分和煤粒燃烧模型 半宽度9(m)、高32(m)的燃烧室如图1所示被分成11个体区和10个面区。其中面区6为燃烧器所在区域,体
I. INTRODUCTION The calculation procedures designed by the author based on Monte Carlo method have been used in the international flame. The calculation of the heat transfer from the furnaces of two foundations of the Foundation (burning oil and natural gas respectively) was conducted with very satisfactory results. In this paper, the original model is improved to fit the industrial scale coal-fired furnace and the simulation of No.1 ~ # furnaces at Bayswater Power Station in New South Wales is carried out. The sensitivity of the model results to coal input changes is emphasized. Second, the numerical model 1. Calculation of the regional division and coal combustion model Half width 9 (m), high 32 (m) of the combustion chamber as shown in Figure 1 is divided into 11 body regions and 10 noodles. Area 6 is the burner area, body
