Effect of 600 MW Supercritical Steam Turbine Prolonging Running Time of Mixing Valve on Unit Vibration

发电技术, 2019
The bearing vibration of No.2, No.3, No.4, No.5, No.6 of a 600 MW supercritical steam turbine in a power plant is relatively large. In order to solve this problem, the intake mode of the steam turbine was changed by prolonging the operation time of the ...

Configuration Optimisation of Integrated Wind–PV–CSP Power Generation to Enhance Grid Support in High‐Renewable Power Systems

IET Smart Energy Systems, EarlyView.
An 8760‐hour optimisation model is developed for integrated wind–PV–CSP systems. Full‐factorial configuration and sensitivity analyses identify a clear optimal structure under grid and turbine constraints, enabling balanced trade‐offs among economic performance, peak‐period supply capability and energy utilisation and providing practical references for

Mergers and Acquisitions as Navigators of Climate Policy Shocks: Evidence from the NOx Budget Trading Program

Financial Management, EarlyView.
ABSTRACT We examine how mergers and acquisitions (M&As) enable firms to adapt to climate policy shocks. Exploiting the adoption of the Nitrogen Oxides (NOx) Budget Trading Program (NBP) across US states as an exogenous shock, we find that firms with NOx‐emitting plants subject to the NBP are more likely to engage in M&As, particularly through vertical ...

Organizing Buyer‐Side Scope 3 Governance: Sensemaking in Supply Network Decarbonization

Journal of Supply Chain Management, EarlyView.
ABSTRACT For many large manufacturers and consumer brands, most greenhouse gas emissions arise outside their own operations and within supplier networks they do not fully control. However, regulators and investors increasingly expect firms to show credible progress on reducing these emissions.

Seismic Tremor as a Precursor to Hydrothermal Explosions Near Mutnovsky Volcano (Kamchatka)

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Mutnovsky Volcano, ∼70 km SW of Petropavlovsk‐Kamchatsky, exhibits persistent degassing, hosts active hydrothermal springs and the Mutnovsky Geothermal Power Plant (MGPP) on its slopes. Using the network covariance matrix approach, we analyzed seismic data recorded in 2023–2024 by 15 seismic stations operating around Mutnovsky Volcano.

Environmental Thermoeconomic Performance Analysis of Gas Steam Combined Cycle With Different Inlet Air Cooling Technologies

Energy Science &Engineering, Volume 14, Issue 8, Page 3638-3655, August 2026.
This study establishes an environmental thermoeconomic cost model to investigate the impact of two IAC technologies on the performance of a GSCC from three aspects of energy, economy, and environment. Under arid climate conditions, the SEC technology demonstrates superior performance in terms of cost‐effectiveness and environmental impact.
