APPARATUS FOR GENERATING REHEAT STEAM

摘要

The present invention relates to an apparatus for supplying and generating steam and mist in the form of reheat steam. According to the present invention, there is provided an apparatus for generating reheat steam including: a combustion chamber; a steam chamber; a plurality of steam-heating pipes; an exhaust chamber; and a heating chamber. According to the present invention, since it is possible to produce a reheat steam by primarily and secondarily heating the steam and mist supplied from the outside by the installation structure of a plurality of steam heating pipes, it is possible to improve the generation efficiency of the reheated steam.

主权项

1. An apparatus for generating reheat steam comprising:
a combustion chamber that is formed with a space portion having a specific volume and has a burner installed at a center of an upper end of the inside; a steam chamber which is provided with a space portion having a specific volume around an outer circumference of the combustion chamber, and preliminarily heats the steam or atomized mist of a specific temperature supplied from the outside using the heat transferred from the combustion chamber; a plurality of steam-heating pipes which are wound inside the combustion chamber in the form of a coil to secondarily heat the steam or the mist supplied after being preliminarily heated in the steam chamber into reheat steam at a specific temperature by means of flames generated from the burner; an exhaust chamber which is formed at a specific volume around the outer circumference of the steam chamber and communicates with the combustion chamber to discharge the exhaust gas combusted in the combustion chamber through the gas exhaust pipe; and a heating chamber which is formed at a specific volume around the outer circumference of the exhaust chamber to heat the steam or air supplied from the outside using heat transferred from the exhaust chamber, wherein in the steam heating pipe, a first steam heating pipe and a second steam heating pipe with an inlet communicating with the steam chamber and an outlet connected to the steam discharge pipe are installed in proximate with an inner wall surface of the combustion chamber, and the first steam heating pipe and the second the steam heating pipe are alternately formed in a coil shape, while the second steam heating pipe is located on the top of the first steam heating pipe at a fixed distance, and a third steam heating pipe and a fourth steam heating pipe with an inlet communicating with the steam chamber and an outlet connected to the steam discharge pipe are installed in proximate with the first steam heating pipe and the second steam heating pipe, and the third steam heating pipe and the fourth the steam heating pipe are alternately formed in a coil shape, while the fourth steam heating pipe is located on the top of the third steam heating pipe at a fixed distance.
