Novel bunker bay structure of main power house of thermal power plant
The invention discloses a novel thermal power plant main power house bunker bay structure which is characterized in that a coal mill is arranged in a main power house, the main power house comprises five rows of shaft columns used for separating space, a bunker bay is located between a third row of shaft columns and a fourth row of shaft columns, and the coal mill is located between the third row of shaft columns and a fifth row of shaft columns. By additionally arranging the fifth column of shaft columns, the distance between the third column of shaft columns and the fourth column of shaft columns is reduced within the same occupied area, the span of the coal bucket girder of the bunker bay can be effectively reduced, the deflection of the coal bucket girder is reduced, the section thickness of the coal bucket girder is reduced, and the stress of the bunker bay is optimized. The span between coal bunkers is reduced, the bending strength of the coal bucket girder is improved, and the construction difficulty of the coal bucket girder is reduced. The span of the bunker bay is reduced, the building size of the bunker bay can be reduced, the strength requirement for bearing the coal bucket can be met through the coal bucket girder with the smaller cross section size, and therefore materials can be saved to a certain degree.
本发明公开了一种新型火力发电厂主厂房煤仓间结构，所述主厂房内设有磨煤机，所述主厂房包括五列用于分隔空间的轴柱，所述煤仓间位于第三列轴柱和第四列轴柱间，磨煤机位于第三列轴柱和第五列轴柱之间。本发明通过增设第五列轴柱，在同等占地面积内减小第三列轴柱和第四列轴柱的间距，可有效降低煤仓间煤斗大梁的跨度，减小煤斗大梁的挠度，进而降低煤斗大梁的截面厚度，优化煤仓间的受力。本发明缩小了煤仓间的跨度，提高了煤斗大梁的抗弯强度，降低了煤斗大梁的施工难度。本发明缩小了煤仓间的跨度，不但可降低煤仓间建筑体积，而且以更小截面尺寸的煤斗大梁也能满足承载煤斗的强度要求，因此可一定程度地节约材料。
