Abstract

PURPOSE:To prevent a heat medium from being contaminated by preventing the oxidation of the internal surface of a heat collecting pipe by a method wherein when the heat collecting pipe is heated during the step of deairing the titled solar heat collecting cylinder, the inside of the heat collecting pipe is kept in a non-oxidizing gas atmosphere. CONSTITUTION:The gas in the body 2 of the solar heat collecting cylinder 1 is discharged by the operation of a vacuum pump 12. In the course of the above gas discharge process, a gas furnace 10 is ignited to heat from outside the solar heat collecting cylinder 1 to a high temperature and at the same time, a nitrogen gas of about 10l/min is supplied into the heat collecting pipe 3 from a gas supply source 15 via a gas supply pipe 14 and the air in the heat collecting pipe 3 is substituted by the nitrogen gas so that the inside of the heat collecting pipe 3 is kept in a nitrogen gas atmosphere. Consequently, the oxidation of the internal surface of the high temperature heat collecting pipe 3 due to the deairing process is prevented and the contamination of the heat medium within the pipe 3 due to oxidized compounds is prevented.
