【摘要】：基于正交設計理論和灰色關聯(lián)理論對新型板式省煤器的結構參數進行了優(yōu)化研究.選取3種優(yōu)化變量(長軸長度、短軸長度和板間距),采用正交設計方法確定9組計算模型.綜合模擬結果與仿真驗證分析得到新型板式省煤器的優(yōu)化結果,當煙氣走板間波紋通道、水走板內循環(huán)通道時,在新型板式省煤器長軸長度、短軸長度和板間距3種優(yōu)化變量中,對優(yōu)化指標影響最大的因素是板間距,其次是長軸長度,影響最小的是短軸長度.當板長為400mm時,新型板式省煤器的最優(yōu)結構參數組合為,長軸長度為32mm、短軸長度為12mm、板間距為25mm.并搭建試驗臺,對此最優(yōu)結構進行試驗驗證。研究結果為板式省煤器的設計提供一種思路.
[Abstract]:Based on orthogonal design theory and grey correlation theory, the structural parameters of a new type of plate economizer are studied. Three kinds of optimization variables (long axis length, short axis length and plate spacing) were selected, and 9 groups of calculation models were determined by orthogonal design method. The optimization results of the new type plate economizer are obtained by synthesizing the simulation results and the simulation verification analysis. When the flue gas goes through the corrugated channel between the plates and the water goes through the inner circulation channel of the plate, the length of the long axis of the new type plate economizer is obtained. Among the three optimization variables of short axis length and plate spacing, the most important factor is the plate spacing, the second is the long axis length, and the least is the short axis length. When the length of the plate is 400mm, the optimum structural parameters of the new type economizer are as follows: the length of the long axis is 32mm, the length of the short axis is 12mm, the distance of the plate is 25mm. The test bench is built and the optimal structure is tested and verified. The results provide a way for the design of plate economizer.
