Title:
EXHAUST GAS RESIDUAL HEAT RECOVERY DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/162117
Kind Code:
A1
Abstract:
In a duct leading to a chimney (10) which discharges exhaust gas to the atmosphere, an exhaust gas residual heat recovery device (1) is provided with a dry economizer (2) which uses the sensible heat of exhaust gas to heat water-to-be-heated; and a condensation economizer (4) which is provided on the downstream side of the dry economizer (2), and uses the condensation latent heat of exhaust gas to heat the water-to-be-heated. The duct comprises a first stage duct (6) wherein the dry economizer (2) is provided, and a latter stage duct (8) which is connected to the first stage duct (6), and changes exhaust gas flow into rising flow. The condensation economizer (4) is installed in the latter stage duct (8). The configuration of the duct is such that the exhaust gas reaches the condensation temperature in the vicinity of an upper section (5) of the condensation economizer (4).
