    摘要: The present invention provides a fire extinguishing apparatus being inexpensive in manufacturing cost, easy to handle, and it enables a storage tank to be refilled with fire extinguishing sand during a fire extinguishing. A fire extinguishing apparatus of the present invention includes a sand container having fire extinguishing sand a nitrogen gas cylinder, and an ejector provided nitrogen gas taken out via a decompression valve from the nitrogen gas cylinder. The ejector is connected to a suction tube sucking the fire extinguishing sand from the sand container using negative pressure generated by a nitrogen gas stream and a delivery tube delivering the sucked fire extinguishing sand and the nitrogen gas. The sand container has a lid plate provided with a sand inlet enabling opening and closing, which enables the sand container to be refilled with the fire extinguishing sand during a fire extinguishing.
