Title:
METHOD FOR PREVENTING IGNITION AND DEVICE FOR PREVENTING IGNITION IN PULVERIZER
Document Type and Number:
WIPO Patent Application WO/2011/142368
Kind Code:
A1
Abstract:
The disclosed device includes: an air supplying means (12) that supplies air; a gas supplying means (13) that supplies a gas in which the partial pressure of oxygen is lower than the partial pressure of oxygen in air; a gas-supply-amount adjustment means (15) that adjusts the amount of the gas supplied; a carbon-monoxide-concentration measurement means (7) and an oxygen-concentration measurement means (6) that respectively measure the concentration of carbon monoxide and the concentration of oxygen at the exit of a pulverizer (5). In the pulverizer (5), which is for pulverizing solid fuel and to which the air and the gas are supplied as a mixed gas, the gas-supply-amount adjustment means (15) is controlled by a control means (11) on the basis of the measurement results of the carbon-monoxide-concentration measurement means (7) and the oxygen-concentration measurement means (6) in a manner so as to change the partial pressure of oxygen in the mixed gas supplied to the pulverizer (5). With this constitution, ignition within the pulverizer (5) can be prevented.
