To provide a use device of a liquefied combustible gas capable of easily and inexpensively gasifying a liquefied combustible gas especially in a cement production facility.SOLUTION: There is provided a use device of a liquefied combustible gas comprising a combustible gas pipeline which communicates: a tank which is attached to a cement production facility comprising a calcination furnace, a cement kiln, and a clinker cooler coupled to a part in front of a furnace of the cement kiln, and stores the liquefied combustible gas in a liquid state; and a blowing part which is set on at least one position belonging to a group formed of a part in front of the furnace of the cement kiln, a tail part of the furnace of the cement kiln, and the calcination furnace, through one or both of the clinker cooler, and inside of a gas extraction pipeline in which the extraction gas extracted from the clinker cooler circulates. The combustible gas pipeline gasifies the liquefied combustible gas in the liquid state during circulation in the combustible gas pipeline, and then, supplies the combustible gas obtained by gasifying the liquefied combustible gas to the blowing part.SELECTED DRAWING: Figure 3 【課題】特にセメント製造工場において液化可燃性ガスを簡易且つ安価な方法で気化させることを可能にする、液化可燃性ガスの利用装置を提供する。【解決手段】液化可燃性ガスの利用装置は、仮焼炉、セメントキルン、及びセメントキルンの窯前部に連絡されたクリンカクーラを有するセメント製造設備に付設可能に構成され、液化可燃性ガスが液体状態で貯留されたタンクと、セメントキルンの窯前部、セメントキルンの窯尻部、及び仮焼炉からなる群に属する１箇所以上に設定された吹込み箇所とを、クリンカクーラ、及びクリンカクーラから抽気された抽気ガスが通流する抽気配管内の一方又は双方を経由して連絡する可燃性ガス用配管を備え、可燃性ガス用配管は、液体状態の液化可燃性ガスを当該可燃性ガス用配管を通流中に気化させた後、液化可燃性ガスが気化されて得られる可燃性ガスを吹込み箇所に供給する。【選択図】図３
