This standard specifies the product type, basic parameters, technical requirements, test methods, inspection rules and marking, packaging, transportation and storage of electronic weighing coal feeders (hereinafter referred to as "coal feeders"). This standard is mainly applicable to the coal feeding system of power generation coal-fired boilers that utilizes the principle of gravity to quantitatively control the transport flow of bulk materials on the conveyor belt in a continuous weighing manner and determine its cumulative mass, with a structural form of pressure resistance level For electronic weighing coal feeder products of no less than 0.35MPa, quantitative feeder products with the same principle and similar structure can be implemented as a reference.
