Study on Continuous Measurement of Material Level Based on Dusty Environment such as Ash Storage

Article Preview

Abstract:

The ash storage is indispensable equipment in the coal-fired power plant, it used to store coal ash. The accurate measurement of coal ash level in the storage can ensure the boiler ash discharge smoothly. But the ash level measurement problems with dust, low dielectric constant, negative / positive pressure and long measuring distance (up to 70 m) etc., resulting in material level measurement becomes a major difficulty in level measurement technology. This paper puts forward a kind of mechanical measurement methodHeavy hammer-level meter detection based on investigation and research around the Hubei power plant. Practice has proved that this measurement method has the advantage of high measuring accuracy, little maintenance, great economic value and it can reduce the maintenance cost of power plant. At the same time this paper also provides some basis for the other studies on continuous measurement of material level.
