LEA Coal Meters


Thread Starter


I want to measure/weigh coal entering a coal fired grate boiler. The boiler used a LEA COAL METER which has been obsolete for years. What similar method can i use to measure the coal?

Does anyone know the principle of operation of the LEA COAL METER? I am stuck.
Surface mining and deep underground mining are the two basic methods of mining. The choice of mining method depends primarily on depth, density, overburden, and thickness of the coal seam; seams relatively close to the surface, at depths less than approximately 55 m (180 ft), are usually surface mined.
