摘　　要：以江西大唐国际抚州发电有限责任公司新建工程(装机容量为2×1 000 MW)为依托,在机组采用侧煤仓方案的前提条件下,根据该电厂的具体条件和特点,提出了炉前除氧间布置方案(投标方案)。将此方案与传统的内除氧间方案进行比较(包括主厂房布置、土建结构、管道和电缆布置以及投资等)后表明,炉前除氧间布置方案缩短了汽机房和锅炉房之间的距离,节省了空间和"四大管道"用量;取消常规内除氧间后,大的辅机布置于炉侧,汽机房跨度和纵向尺寸可进一步压缩,减少了占地面积,从而降低了初投资。Taking the new project of Jiangxi Fuzhou Datang International Power Generation Co. , Ltd. as background （ installed capacity 2× 1 000 MW ）, the layout scheme of deaerator bay in front of boiler furnace （ bidding scheme ） was proposed, according to the condition of side bunker, the specific conditions and characteristics of the power plant. The proposed scheme was compared with traditional internal deaerator bay scheme, including the layout of main building, the civil engineering structures, the layout and investment of pipes and cables. The results show that the distance between boiler house and turbine house can be shortened, and the space and the dosage of four critical pipelines can be saved in the proposed scheme. In addition, the main auxiliary can be arranged on side of furnace without internal deaerator bay, which can further compress the span and longitudinal dimension of turbine house, as well as reduce the floor space and the initial investment.
