Synthesis of green nanomaterial and discussion on its suppression performance and mechanism to aluminum dust explosion

Chemical Engineering Research and Design, 2021
Abstract In order to develop a green and efficient nano suppressant for aluminum (Al) dust explosion, MCN with layered structure was synthesized with low-cost urea as precursor via simple calcination technology. The suppression performance of MCN on the flame propagation of 30 μm and 5 μm Al dust with the concentration of 1000 g/m3 was experimentally

A Mechanism for the Suppression of a Steam Explosion in Real Core Melt and Water Interactions

Journal of Nuclear Science and Technology, 2010
TROI experiments1) have been performed to reveal unsolved issues of a steam explosion by using real core material at the Korea Atomic Energy Research Institute (KAERI). One of the findings from the TROI experiments is that the results of a fuel coolant interaction (FCI) are strongly dependent on the composition of corium, which is composed of UO2, ZrO2,

Mechanism and experimental investigation on the suppression of thermobaric explosive explosions by water mist in confined spaces

Physics of Fluids
Addressing the urgent need for mitigating the hazards of Thermobaric Explosives (TBX) in confined spaces, this study develops a multi-stage explosion pressure model incorporating detonation, combustion, and pressure oscillations to support accurate prediction of blast threats. An energy redistribution-based suppression model for water mist is proposed,

Suppression of hydrogen-methane explosion flames by metal wire mesh: Heat loss effect and explosion suppression mechanism

Hydrogen-blended natural gas transportation is an important pathway for carbon reduction. However, hydrogen addition significantly enhances the deflagration intensity of methane, imposing more stringent requirements on the reliability of metal wire mesh flame arresters, which are key pipeline safety components.

Study on the Characteristics and Mechanisms of KHCO₃ Powder in Suppressing Methane Explosions in the Pipeline Network

Langmuir
Methane is a widely used form of clean energy in daily production and life. To prevent the potential threat of explosions caused by methane leakage during transportation, potassium bicarbonate (KHCO3) powder was selected for methane explosion suppression experiments based on an independently designed and constructed explosion pipeline network ...
