Impact of Temperature Increases on Formation of Carbon Monoxide during Lignite Storage

Popis výsledku v původním jazyce

This article presents our research on the formation of carbon monoxide (CO) through low temperature oxidation of lignite coal during its long-term storage in the coal bunkers of fluidised bed boilers. Our work shows that CO concentration in the vicinity of coal storage facilities poses real danger to the operating staff, especially in cases when the temperature of coal or the facility may suddenly rise. The experiments with lignite samples revealed CO can be released at temperatures higher than ambient (ca 50-180 degrees C) in concentrations of up to 2,500 ppm. The cause is the oxidation of stored coal matter by air. We showed that any step increase in the temperature of the coal always leads to immediate short-term peak increase in CO formation. In all cases, these peak CO concentrations reached levels higher than both the maximum permissible exposure limit and the maximum permissible concentration in the working environment air.
