Title:
HEAT PIPE STEAM GENERATOR
Document Type and Number:
WIPO Patent Application WO/2020/114261
Kind Code:
A1
Abstract:
A heat pipe steam generator, comprising a boiler (1), a generator (2), and a combustor (3). A combustion end of the combustor (3) extends into a hearth (11) of the boiler. The boiler (1) is connected to the generator (2). The generator (2) is provided with a heat pipe (21). A primary side channel is formed outside the heat pipe (21). A secondary side channel is formed in the heat pipe (21). Heat exchange is made between a medium in the primary side channel and a medium in the secondary side channel. The boiler (1) is connected to the primary side channel of the generator (2) to form a primary side circulation loop which is vacuum-tight. The height of the minimum level of the primary side channel is greater than the height of the maximum level of the boiler (1). The height difference between the level of the primary side channel and the level of the boiler (1) ensures that in one primary circulation loop, the aqueous solution in the generator (2) can still be returned to the boiler (1) in the case that no power is provided by a water pump so as to protect the external oxidizing gas from being sucked into a primary side water circulation loop and prolong the service life of the boiler (1).
