STOKER-TYPE GARBAGE INCINERATOR PROVIDED WITH WASTE HEAT RECOVERY BOILER
Document Type and Number:
WIPO Patent Application WO/2017/170661
Kind Code:
A1
Abstract:
A stoker-type garbage incinerator provided with a waste heat recovery boiler. The stoker-type garbage incinerator is formed with a combustion chamber, a first flue, a top turn-back part (31), and a second flue (22), and the incinerator is provided with a partition wall (44) and a ceiling wall (45, 46). The waste heat recovery boiler has a final-stage superheater (57) comprising a plurality of double pipes (82). The plurality of double pipes (82) pass through a portion (46) of the ceiling wall (45, 46) positioned above the second flue (22), and are suspended in the vertical direction. Each double pipe (82) has an inner pipe (83) for transmitting steam, and an outer pipe (84) surrounding the outside of the inner pipe (83) and transmitting steam in the opposite direction from the inner pipe (83). The outer pipe (84) has a curved bottom part at the bottom end to send back the steam transmitted to the bottom end thereof. The partition wall (44) blocks direct radial heat from the combustion chamber so that the radial heat does not reach the final-stage superheater (57).
