Title: Water level controller for boiler
IPC: F22D5/24
Filed: 1992-03-11
Abstract: PURPOSE:To realize positive water level control even with a single water level detecting electrode rod, by a method wherein a water supply pump is operated for a predetermined period of time to supply water, when the electrode rod detects absence of water. CONSTITUTION:One or a plurality of water level detecting electrode rods Z are provided inside a water level detecting cylinder 1. An operation time T2 of a water supply pump 8 can be determined based on a time T1 to be elapsed after one of the electrode bar 2 of the electrode rods Z detects no-water to start water supply before presence of water is detected again. In addition, based on the time T1 and a time T3 to be elapsed after stoppage of water supply pump 8 before detection of no-water by the electrode bar 2, a decision can be made whether T1 is increased because capacity of the water supply pump 8 is too low or because steam load is too high. Thus, the operation time of the water supply pump 8 can be controlled depending on the capacity of the water supply pump 8 or the steam load.

IPC: F25B37/00
Filed: 1995-04-14
Abstract: PURPOSE: To enable a continuous operation of an absorbing type freezer to be performed irrespective of a pressure reduced boiling action of absorbing liquid in an absorbing device. CONSTITUTION: Absorbing liquid Ld flowed from a dispersion device is collected by a liquid guiding member 15 and guided to a liquid feeding part 12 of a storing part 9, and in turn, a liquid flow passage 13 released toward a liquid surface side of the absorbing liquid Ld and extending from the liquid feeding par 12 toward a liquid taking-out part 11 while being bypassed in either a vertical direction or a horizontal direction is formed within the storing part 9. With such an arrangement as above, even if an inner pressure of the absorbing device 1 is decreased and air bubbles F caused by pressure reduced boiling of the absorbing liquid Ld in the storing part 9 are produced, the air bubbles F are dispersed to an upper part of the absorbing device 1 while they are flowed in a liquid flow passage 13 and so the air bubbles are not sucked into a pump 5. Accordingly, non-operative operation of the pump 5 caused by suction of the air bubbles F can be avoided, a non-operative operation of the absorbing type freezer can be positively avoided and further a reliability in operation of the device can be improved.
