Abstract

The invention relates to an arrangement structure of a nuclear power station oil and gas boiler room. The arrangement structure of the nuclear power station oil and gas boiler room comprises an auxiliary boiler room, a boiler oil pump room and an oil tank area, wherein the auxiliary boiler room is divided into two layers on the ground according to the scale height; the boiler oil pump room and theoil tank area are divided into one layer on the ground; three oil and gas boilers and auxiliary equipment and matching pipelines thereof are arranged in the auxiliary boiler room; a boiler room and an equipment control room are isolated physically; heavy oil tanks and light oil tanks are arranged in the oil tank area; heavy oil and light oil are conveyed to a stokehole valve bank of each oil andgas boiler through an oil conveying pump in the boiler oil pump room; and a natural gas pipeline is connected to the stokehole gas valve bank of each oil and gas boiler. According to the arrangement structure of the nuclear power station oil and gas boiler room provided by the invention, through the design, the space is reasonably utilized, the working environment is improved, the occupational safety is improved, and the steam use requirement of nuclear power station auxiliary steam can be met.

Description

technical field [0001] The invention belongs to the nuclear power plant building design technology, and in particular relates to an arrangement structure of a nuclear power plant fuel gas boiler room. Background technique [0002] The layout of the boiler room is the most critical work in the design of the boiler room. Whether the layout is reasonable or not has an important relationship with the infrastructure investment, floor area, energy consumption, and operation safety and economy of the entire boiler room. Therefore, in the design, all aspects should be considered as comprehensively as possible, and reasonable and economical solutions should be proposed. [0003] The main function of the auxiliary boiler is to provide auxiliary steam to the auxiliary steam distribution system to meet the steam demand of each steam user before the nuclear island unit is put into normal operation. The steam users mainly include the main deaerator of the conventional island, the steam tu...
