Title:
RADIANT HEAT RECOVERY HEATER, AND STIRLING ENGINE AND COMBUSTION FURNACE USING RADIANT HEAT RECOVERY HEATER
Document Type and Number:
WIPO Patent Application WO/2015/194365
Kind Code:
A1
Abstract:
Provided is a radiant heat recovery heater having high heat exchange performance. Also provided are a Stirling engine and a combustion furnace using this heater. In this radiant heat recovery heater (1), the attachment pitch circle of one passage (121) of U-shaped heat transfer tubes (12) is formed with a small diameter at a heater attachment section (11), and the attachment pitch circle of the other passage (122) is formed with a large diameter, and these heat transfer tubes are contained in a container (13) affixed to the attachment section (11), with radiant heat from the container (13) being absorbed by the U-shaped heat transfer tubes (12) when the container (13) is exposed to a high temperature. In the U-shaped heat transfer tubes (12), the one passage (121) and the other passage (122) are arranged at equal intervals on the attachment section with a pitch angle (θ), with the one passage (121) being arranged on the attachment section (11) at a position offset from the pitch angle (θ) of the other passage (122) by a prescribed angle (α), so as not to completely overlap a projection plane (122A) of the other passage (122) from the container (13) toward the center (C) of the container (13).
