【摘要】：基于正交設(shè)計(jì)理論和灰色關(guān)聯(lián)理論對(duì)新型板式省煤器的結(jié)構(gòu)參數(shù)進(jìn)行了優(yōu)化研究.選取3種優(yōu)化變量(長(zhǎng)軸長(zhǎng)度、短軸長(zhǎng)度和板間距),采用正交設(shè)計(jì)方法確定9組計(jì)算模型.綜合模擬結(jié)果與仿真驗(yàn)證分析得到新型板式省煤器的優(yōu)化結(jié)果,當(dāng)煙氣走板間波紋通道、水走板內(nèi)循環(huán)通道時(shí),在新型板式省煤器長(zhǎng)軸長(zhǎng)度、短軸長(zhǎng)度和板間距3種優(yōu)化變量中,對(duì)優(yōu)化指標(biāo)影響最大的因素是板間距,其次是長(zhǎng)軸長(zhǎng)度,影響最小的是短軸長(zhǎng)度.當(dāng)板長(zhǎng)為400mm時(shí),新型板式省煤器的最優(yōu)結(jié)構(gòu)參數(shù)組合為,長(zhǎng)軸長(zhǎng)度為32mm、短軸長(zhǎng)度為12mm、板間距為25mm.并搭建試驗(yàn)臺(tái),對(duì)此最優(yōu)結(jié)構(gòu)進(jìn)行試驗(yàn)驗(yàn)證。研究結(jié)果為板式省煤器的設(shè)計(jì)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.
