Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust
Feature: Coal Pulverization System: Explosion Prevention and Process Control 2. Explosion prevention and protection Principle of dust explosion prevention and protection has been introduced by Eckhoff . The main methods used in this system include atmospheric inert-ing, powder inerting (during stop and restart) and venting. Process control is also a part of explosion prevention. 2.1
Dec 09, 2011· Prevention of coal mine explosions requires a suite of control strategies, including sustaining a properly designed ventilation system, adequate sealing of abandoned areas, aggressive and frequent monitoring of methane, reduction of coal dust accumulations, and control of potential ignition sources through electrical safety and the use of permissible equipment.
For pulverization of coal the most commonly used are the medium speed coal mills. Challenges Faced in a Coal Mill. Coal that has accumulated or settled in any of the coal mill components during the pulverising process tends to catch fire. Coal explosion can occur inside the coal mill, while grinding coal, due to various reasons like
