Zusammenfassung:PROBLEM TO BE SOLVED: To provide an emulsion fuel supply device using no additive agent.SOLUTION: An emulsion fuel supply device 101 is installed between a fuel storage tank S and a combustion part B of an existing warm-air blower WS, and at a start stage of combustion, supplies only the fuel stored in the fuel storage tank S to the combustion part B to cause the combustion part B to burn only with the fuel. With this, stable combustion is easily achieved at an early stage of combustion. Further, at a combustion stage, a fuel pipeline control valve 131, a water pipeline control valve 133 and an emulsion fuel pipeline control valve 135 are controlled so that all of the respective valves are in the open state to cause the combustion part B to stably burn with the emulsion fuel. When the combustion is terminated, paths comprising a fuel supply passage R1 which leads from the fuel storage tank S to the combustion part B, a mixture supply passage R4 and an emulsion fuel supply passage R5 are filled with the fuel stored in the fuel storge tank S. Accordingly, the emulsion fuel does not stagnate in the respective pipelines, and deterioration of the facilities is prevented. 【課題】 添加剤を使用しないエマルジョン燃料供給装置の提供【解決手段】 エマルジョン燃料供給装置101は、既設の温風送風機WSの燃料貯蔵タンクSと燃焼部Bとの間に設置され、燃焼開始段階においては、燃焼部Bに、燃料貯蔵タンクSが貯蔵する燃料のみを供給し、その燃料のみによって燃焼部Bを燃焼する。これにより、容易に燃焼初期における安定した燃焼を実現する。また、燃焼段階では、燃料管路制御バルブ131、水管路制御バルブ133、エマルジョン燃料管路制御バルブ135、いずれも開状態となるように各バルブを制御し、エマルジョン燃料によって燃焼部Bを安定的に燃焼させ、燃焼が終了したとき、燃料貯蔵タンクSから燃焼部Bに通じる燃料供給路R1、混合供給路R4、エマルジョン燃料供給路R5からなる経路を燃料貯蔵タンクSが貯蔵する燃料で満たす。よって、エマルジョン燃料が各管路内に滞留することがなく、設備の劣化を防止する。【選択図】 図1
