Improvement of coal fired power plant's performance by use of wear resistant components

Importance of coal fired power plants in global production of electric energy is continuously increasing. In power plants that burn pulverized coal, coal pulverizers (coal mills) grind larger coal particle. Short working period, high costs and frequent breakdowns of elements used in pulverizing process in coal fired power plants represent problems that every plant's maintenance department is aware of. This paper deals with rotary mill's beater bars for pulverising of coal. New type of beater bars, more resistant to abrasion, erosion and impact wear is developed and tested. Aim of tested beater bars is to reduce maintenance stops and costs, increase production of electrical energy and reduce total cost of ownership.
