Description

Technical Field

[0001] The utility model relates to the field of high- and low-pressure heating pipelines, in particular to a steam source connection optimization system for high- and low-pressure heating pipelines. Background Art

[0002] Due to the influence of the power grid, the units are frequently deeply peaked, and the low-load operation of the units during peak load adjustment causes the four-stage steam extraction to be unable to supply heat (low-pressure industrial heating). At present, low-pressure industrial heating adopts the operation mode of supplying steam from the high-pressure heating header to the low-pressure heating header. However, due to the connection pipeline, the high-pressure side interface is φ377×22, the low-pressure side interface is φ426×25, and the maximum design flow is 100t / h. The actual heat supply has exceeded the design value, resulting in the low-pressure industrial heating system being unable to meet the needs of various users under the condition of deep peak load adjustment of the units.
