Heat pipe type steam generator

Abstract

The invention relates to a steam generation device, in particular to a heat pipe type steam generator. The heat pipe type steam generator comprises a boiler, a generator body and a combustor. The combustion end of the combustor stretches into a hearth of the boiler. The boiler is connected with the generator body. A heat pipe is arranged in the generator body. A primary side channel is formed outside the heat pipe. A secondary side channel is formed in the heat pipe. Media in the primary side channel exchange heat with media in the secondary side channel. The boiler is connected with the primary side channel of the generator body so that a primary side cycle loop can be formed, and the primary side cycle loop is vacuum and is closed. The height of the lowest liquid level of the primary side channel is larger than the height of the highest liquid level of the boiler. By utilization of the height difference between the liquid level in the primary side channel and the liquid level of theboiler, it is guaranteed that in the primary side cycle loop, the water solution in the generator body can still return into the boiler under the situation that no water pump supplies power, accordingly, outside oxidized gas is prevented from being sucked into the primary side water cycle loop, and the service life of the boiler is prolonged.

Description

technical field [0001] The invention relates to a steam generating device, in particular to a heat pipe type steam generator. Background technique [0002] Steam generators on the market generally have problems such as high failure rate and short service life. The main reasons for these two problems are that the water capacity of the steam generator is small, the water level is difficult to control and stabilize, and frequent false signal interference causes electrical false alarms; Traditional steam generators have high requirements on water quality, and it is easy to cause irreparable failures of steam generators due to scale problems. [0003] For example, the Chinese patent with publication number CN 202149475U discloses a heat pipe type steam generator, which includes a steam generating chamber and a combustion chamber, wherein a heat pipe is arranged in the steam generating chamber, and the heated end of the heat pipe extends into the combustion chamber. The applicati...
