| description | Using low-pressure cylinder zero output technology can effectively improve the heating capacity and peak regulation capacity of the generation unit. In this paper, taking a 320 MW heating unit for example, firstly, Ebsilon software is used to calculate and analyze the heating performance of low-pressure cylinder zero output. The results show that the application of low-pressure cylinder zero output technology increased the maximum heating extraction steam flow of the unit by 97%, and reduced the net coal consumption by 61 g/(kW·h) at 250 MW heating load. Then, the test study on the heating capacity of low-pressure cylinder zero output mode of the unit was carried out. Field measurements show that the maximum heating load of the unit can reach as much as 476 MW, while the minimum electric load can be reduced to 79.5 MW. At last, based on the operation data of the heating season of previous year, the economic performance of low-pressure cylinder zero output mode is analyzed. The results show that using this heating mode can save 5581 t of standard coal equivalent. |
