Pulverised Coal Start

Feature: Coal Pulverization System: Explosion Prevention and Process Control The controlling logics are: (1) In start procedure, the down-stream devices run before the up-stream devices, so block-up can’t occur. (2) In stop procedure, the up-stream devices stop before the down-stream devices, so there will be little coal (if there is any)

    everywhere that coal is handled, processed or stored. Safe coal handling practices are designed to ensure that the fuel remains intact throughout its journey from the mine until the point at which it is ignited in the boiler. It takes as little as 1.4 kg (3 lbs) of pulverised coal in 28 m3 (1,000 ft3) of air to form an explosive mixture.

  • Pulverised Coal - an overview | ScienceDirect Topics Pulverised Coal - an overview | ScienceDirect Topics

    When pulverised coal (PC) is injected via the tuyeres, carbon reacts with oxygen of the blast and generates CO 2, which reacts with burning hot coke and transforms to carbon monoxide. A crucial problem is related mainly to PC conversion (particularly at high injection rates) because its residence time within the tuyere and the raceway makes up ...

    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 …
