[0001] The utility model relates to the technical field of raw coal production, in particular to an unattended device for a raw coal stacker and reclaimer. Background Art

[0002] Raw coal refers to the product produced by coal mines without washing, screening and processing, but only after manual sorting of gangue and debris. It includes natural coke and low-quality coal, but does not include low calorific value coal (such as stone coal, peat, oil shale, etc.); raw coal can be divided into three categories according to its origin, namely, humic coal, saprophytic coal and humic saprophytic coal.

[0003] Patent announcement number CN219934699U discloses a condensate recovery device for an air separation water bath vaporizer, which solves the problem of condensate waste caused by the discharge of steam condensate from the backup nitrogen system.
