Pulse Detonation Engine for Advanced Oxy-combustion of Coal-Based Fuels Oregon State University (Corvallis, OR) will develop and evaluate a pulse detonation combustion system for magnetohydrodynamics (MHD) – an innovative way to convert a high-velocity coal flame into electricity using a magnetic field – to increase the efficiency of power generation plants.
In order to reduce the cost of running blast furnaces (BFs), injected pulverized coal is used rather than coke to fire BFs. As a result of this, unburned fine materials are blown with the gas into the bosh and dead man areas with possible detrimental effects on gas flow and permeability of the coke column.
But the coal burner saves vast combustion cost, compared to oil burners. The more advanced type, the longer time it works, the more obvious the advantage is. The more advanced type, the longer time it works, the more obvious the advantage is.
