THE INFLUENCE OF THE COAL DUST COMPOSITION ON THE PROPAGATION SPEED OF THE COMBUSTION FRONT OF THE COAL DUST WITH AN INHOMOGENEOUS PARTICLE DISTRIBUTION IN THE AIR

The problem of the combustion of a gas suspension with an inhomogeneous distribution of particles over space occurs exists for the coal dust suspension combustion in combustion chambers and burners.The inhomogeneous distribution of particles in space can significantly affect the combustion velocity of the aerosolve of coal dust.The purpose of the p

Global warming could increase climatic instability and large wildfire activity in circumboreal regions, potentially impairing both ecosystem functioning and human health.However, links between large wildfire events and climatic and/or gtech brush bar meteorological conditions are still poorly understood, partly because few studies have covered a wi

The current transmission line robot up and down the line relies on manual lifting, and this method is labor-intensive, dangerous, and requires the assistance of many people.To address this problem, the paper proposes a control method based on UAV-assisted transmission line power line operation robot up and down the line.Aiming at the characteristic
