[Post=100] 华电国际邹县发电厂四期工程建设初期，首先 确立了“设计一流、可靠先进、节水环保、节能降耗、实用高效、全国示范”的设计原则及“立足四期、面向全厂，降低造价，确保竞争，提高效益”的设计思想。<chsdate isrocdate="False" islunardate="False" day="20" month="10" year="2004" wst="on"></chsdate><chsdate></chsdate>2004年10月20日<chsdate></chsdate><chsdate></chsdate>，国家发改委以发改能源[2003]1529号文件，批准四期工程正式立项。<chsdate isrocdate="False" islunardate="False" day="15" month="1" year="2005" wst="on"></chsdate><chsdate></chsdate>2005年1月15日<chsdate></chsdate><chsdate></chsdate>，主厂房浇灌第一方混凝土，标志着四期工程正式全面开工建设。 <chsdate isrocdate="False" islunardate="False" day="4" month="12" year="2006" wst="on"></chsdate><chsdate></chsdate>2006年12月4日<chsdate></chsdate><chsdate></chsdate>11时18分，我厂7号机组圆满完成168小时满负荷试运行，比计划工期提前9.4个月，整个建设工期22.6个月。该机组的顺利投产，创造了大容量机组建设速度最快、工程造价最低、调试时间最短、整体质量最优的全国记录。机组满负荷试运期间，各项性能指标全部达到优良标准，机组运行平稳，自动、保护、仪表投入率100%，发电煤耗<chmetcnv wst="on" tcsc="0" numbertype="1" negative="False" hasspace="False" sourcevalue="270" unitname="克"></chmetcnv><chmetcnv></chmetcnv>270克<chmetcnv></chmetcnv><chmetcnv></chmetcnv>/千瓦时，机组热效率超过45%，平均负荷率100.06%，同步建设的烟气脱硫装置效率95%以上，除尘效率高达99.9%。机组采用了超超临界、

92等新技术、新材料,完全符合国家建设资源节约型、环境友好型、自主创新型企业的政策。<p class="

TEXT-INDENT: 23.7pt; LINE-HEIGHT: 16.5pt; mso-char-indent-count: 2.25; mso-line-height-rule: exactly; punctuation-trim: leading; punctuation-wrap: simple;">锅炉的循环系统由启动分离器、储水罐、启动再循环泵、下降管、下水连接管、水冷壁上升管及汽水连接管等组成。在负荷D≥25%B-MCR后，直流运行，一次上升，启动分离器入口具有一定的过热度。炉膛水冷壁分上下两部分，下部水冷壁采用全焊接的螺旋上升膜式管屏，螺旋水冷壁管采用了内螺纹管，上部水冷壁采用全焊接的垂直上升膜式管屏。螺旋围绕水冷壁与上部垂直水冷壁的过渡方式采用中间混合集箱形式。<p class="MsoBodyText2" style="TEXT-JUSTIFY: inter-ideograph; MARGIN: 0cm 0cm 0pt; TEXT-INDENT: 23.7pt; LINE-HEIGHT: 16.5pt; TEXT-ALIGN: justify; mso-char-indent-count: 2.25; mso-line-height-rule: exactly;">螺旋管圈水冷壁部分，刚性梁由垂直刚性梁和水平刚性梁构成网格结构，刚性梁体系及炉墙等的自重荷载完全由垂直搭接板支吊，采用了可膨胀的带张力板的垂直刚性梁支承系统，下部炉膛和冷灰斗的荷载能传递给上部垂直水冷壁。刚性梁和水冷壁之间相互不直接焊接，可以相对滑动，以防止附加热应力的产生，保证炉膛安全可靠运行。炉膛水冷壁采用悬挂结构，整个水冷壁和承压件向下膨胀，由于水冷壁的四周壁温比较均匀，因此水冷壁与垂直搭接板之间相对胀差较小，刚性梁与水冷壁相对滑动。过热器及再热器受热面的布置采用了辐射-对流型，这种布置方式可确保锅炉在负荷变化范围内达到额定的蒸汽参数，并获得良好的汽温特性。过热器受热面由四部分组成，第一部分为顶棚及后竖井烟道四壁及后竖井分隔墙；第二部分是布置在尾部竖井后烟道内的水平对流过热器；第三部分是位于炉膛上部的屏式过热器；第四部分是位于折焰角上方的末级过热器。过热汽温调节采用水煤比和二级喷水减温，过热蒸汽管道在屏式过热器与高温过热器之间进行一次左右交叉，以减小两侧汽温偏差。再热器由位于尾部前烟道的水平对流低温再热器及位于高温过热器后的高温再热器组成。再热汽温通过尾部双烟道平行烟气挡板调节。省煤器布置在尾部后竖井水平低温过热器的下方。后竖井省煤器、水平低温过热器均通过省煤器吊挂管悬吊到大板梁上。燃烧器采用前后墙对冲分级燃烧技术。在炉膛前后墙各分三层布置低NOx旋流式HT-NR3煤粉燃烧器，每层布置8只，全炉共设有48只燃烧器。在最上层燃烧器的上部布置了燃尽风喷口（AAP）。每只燃烧器均配有机械雾化油枪，用于启动和维持低负荷燃烧。1．2锅炉设计参数                                  <p class="MsoNormal" style="MARGIN: 0cm 0cm 0pt;
