Title:
BOILER EMPLOYING ROTATIONAL FORCE
Document Type and Number:
WIPO Patent Application WO/2011/031007
Kind Code:
A3
Abstract:
The invention relates to a boiler employing rotational force, comprising: a rotating body (10) connected to a driver generating rotational force for rotating same; and a housing (20) rotatably housing and supporting the rotating body, including a water inlet (24) and outlet (25), and defining a passage (28) through which water that enters the inlet contacts a peripheral surface of the rotating body and flows in an axial direction toward the outlet. A plurality of recessed holes (13) are drilled in the peripheral surface of the rotating body at angles that are skewed relative to a normal or tangential direction. A plurality of recessed grooves (29) are formed in the inner periphery of the housing at regular circumferential intervals, so as to be straight, skewed, or spiraled relative to the axial direction. In the boiler, water flows in the axial direction along the passage and contacts the peripheral surface of the rotating body to significantly increase the sliding distance thereof, and the friction effect is maximized by the plurality of recessed holes. Also, the plurality of recessed grooves not only facilitate the flow of water within the housing, but also improve the intake and discharge of water by means of the inherent suctioning force thereof, as well as the circulation of the water to an external circulation system.
