Combustion gas exhaust pipe i.e. coaxial exhaust pipe, for fuel-heated heater, has feed pipe and return pipe running through thermal insulation and connected to solar absorber, where feed pipe and return pipe are screwable or solderable

摘要

The pipe (1) has a feed pipe (3) and a return pipe (4) running through a thermal insulation (2) and connected to a solar absorber, where the feed pipe and the return pipe are screwable or solderable. A connection pipe (5) of a collector sensor runs through the thermal insulation. An exhaust gas passage (6) and an air passage run conical with each other. The connection pipe is inserted into the collector sensor, where a set of sections of the exhaust pipe is connectable with each other.
