In today’s coal fired power plants, it is important to keep coal dust and coal spillage in the load zone area to a minimum. Many plants struggle to keep these areas clean, due to not having enough time or man power to properly adjust skirt rubber or fix holes in the chutes. Around many load zone areas you will usually find coal piles in between troughing idlers and on the floor. This coal spillage is expensive to remove and if not properly fixed the coal piles will reoccur again and again.
This midwest coal fired power plant had this problem. The skirt rubber wasn’t getting adjusted or changed when needed; piles of coal all around the load zone area floor caused a safety hazard. The existing load zone was missing hoods, dust curtains and was rusting in some areas. All these problems together were causing coal to spill and coal dust to fill the air around the conveyor. More
