Abstract:Aiming at the waste steam venting loss caused by load fluctuations in papermaking production, this paper takes the steam-electric dual-drive air compressor system of a paper mill as the research object and carries out multi-condition characteristic analysis based on field measured DCS data. The results show that the steam intake flow of 10 t/h of the condensing steam turbine in the system serves as the mode switching threshold, with a maximum stable power generation of 3300 kW under high-load conditions. The system can stabilize the main steam pressure at 8.5±0.5 MPa. Compared with the full-electric drive mode, the steam-driven mode reduces the auxiliary power consumption rate of the power plant by 8.93 percentage points and can equivalently replace 721.7 kW of installed capacity of compressed air equipment. The research can provide engineering references for waste steam recovery and energy-saving renovation in paper mills.
