Title: Solar pond
Inventor: TAKAYANAGI MIKIO
IPC: F24J2/00
Filed: 1987-02-03
Abstract: PURPOSE:To make it possible to increase the heat accumulating capacity in a heat accumulating layer not only when the electric power source is out in the plant but also at any time desired by raising the installation level so as to bring the water level of a steam pond higher than the water level of a solar pond and supplying low temperature salt water of a high salt concentration through a valve to the heat accumulating layer of the solar pond. CONSTITUTION:In the normal operation the heat extraction is carried out by using a hot water circulation pump 5, heat exchanger 6 installed outside, and hot water circulating piping 7 with a valve 15 closed in order to meet a thermal load 8. Fresh water which is supplied from a fresh water supply device 13 is poured from above on to the pond surface. The fresh water after the pouring contains salt that is diffused from the bottom of the pond and is transferred to an evaporation pond 9 as needed by a salt-water transfer pump 10. when the electric power source in the plant for a solar pond is out due to an accident or when the hot water circulation pump 5 is out of order or when the demanded heat quantity is zero and the extracted heat becomes zero, there is a tendency that abnormal. overheating occurs in a heat accumulating layer 3. This operation can be made only by the valve opening and closing so that the transfer of the salt water can be made even if the electric power source in the plant is out, because the difference in the static water heads of both ponds is utilized.

Filed: 1989-02-02
Abstract: PURPOSE:To obviate the occurrence of knocking by judging a combustion state in comparing a changed state of heat generating rate stored in a memory means with that found by an operational means. CONSTITUTION:An electronic control unit 9 inputs each signal out of a cylinder internal pressure sensor 4 and a crank angle sensor 6, calculates a heat generating rate with an operational means 13, and finds rise time ¦theta100-theta0¦ with an operational means 14 from the changed state. Next, the calculated rise time ¦theta100-theta0¦ is compared with the absolute set value being prestored and whether it is abnormal combustion or not is discriminated at a discriminating means 15. When it is smaller than the absolute set value and it causes knocking or is in a state of being liable to cause it, a knocking avoiding signal is outputted to various combustion control means. Thus the occurrence of knocking is obviatable.
