Document Type and Number:
Japanese Patent JP6918641
Kind Code:
B2
Abstract:
The purpose of the present invention is to spray a fire extinguishant to suppress fast burn when fast burn occurs in a housing at least in any operating state with differing pressure within the housing. A pulverizer (5) that pulverizes solid fuel to finely powdered solid fuel is provided with: a housing (41) constituting an outer shell for the pulverizer (5); pressure sensors (61A, 61B) for detecting pressure inside the housing (41); a first extinguishant spray unit (60A) for spraying extinguishant when the pressure detected by the pressure sensor (61A) is equal to or greater than a prescribed first threshold value in a normal operating state for the pulverizer (5); and a second extinguishant spray unit (60B) for spraying extinguishant when the pressure detected by the pressure sensor (61B) is equal to or greater than a second threshold value, which is a different threshold value from the first threshold value, in a stopped operating state for the pulverizer (5).
