Title: Microwave power absorbing device
Inventor: YASUTAKE HIROTO
IPC: H01J23/00
Filed: 1992-11-09
Abstract: PURPOSE:To eliminate the reflection of a microwave toward a incident part by forming a conical diverter whose radius is gradually increased with a microwave absorbing body and providing a coolant to the rear side of the diverter so as to absorb the microwave at high efficiency. CONSTITUTION:When a microwave whose power is distributed in Gaussian distribution is made incident, the wave is reflected by a mirror section 33 and the inner wall mirror section 24 of a waveguide 23 as shown in the arrow in full lines in an operating state. Thus, the power density is decreased and reflected waves 30, 31 are made to enter an inner cylinder 34, in which the waves are absorbed. In this case, so long as the reflectance of the inner cylinder 34 is not zero, a part of the incident microwave is reflected, but the reflected waves 30, 31 repeat reflection between a diverter 32 and the inner cylinder 34 and then the waves are attenuated and absorbed. Furthermore, even when the wave propagated around the bottom of the diverter 32 changes its propagation direction toward the input side, the wave repeats reflection between the diverter 32 and the inner cylinder 34 and then is attenuated and absorbed. Moreover, the incident microwave is efficiently absorbed by a cooling water at the rear side of the diverter 32 and the reflection is eliminated.

Filed: 1996-11-11
Abstract: PROBLEM TO BE SOLVED: To improve heat efficiency and save cooling water by interposing a heat exchanger on a boiler water supply system and hence exchange heat between blowdown water and condensate. SOLUTION: Impurities such as circulation water are concentrated in a vapor drum 2 in a boiler 1 so that blowdown is performed to keep quality of boiler water at a predetermined reference or lower. Blowdown water is subject to steam-water separation in a blow flash tank 5, and saturated vapor is introduced into a deaerator, etc., for heat recovery.
