Filed: 1990-02-28
Abstract: PURPOSE:To maintain a stability of reactor core part and to enable maintaining a low power operation by reducing a rotation of a recirculation pump to the lowest allowable flow rate at an occasion of a generator load to be cut off, and by tripping the pump at an occasion of failed run-back operation. CONSTITUTION:In case that a generator load is cut off 1 when a nuclear reactor output is higher than a specific value, the reactor output is made to decrease 7 by reducing rotation of a recirculation pump to a rotation speed giving the lowest allowable flow rate of the pump by inserting 5 selective control rods and by running-back 40 of the circulation pump. Moreover, when the running- back of the recirculation pump is failed 41 or turbine by-pass valves do not work 8, the nuclear reactor is made to scram 10 and the recirculation pump is made to trip 6, as well. With these procedures, an operation under a natural convection condition which is less stable for a reactor core part, can be avoided, during sudden closing 3 of a turbine control valve and sudden opening 4 of a turbine by-pass valve, and therefore a low output operation can be maintained.

IPC: F23Q25/00
Filed: 1979-04-18
Abstract: PURPOSE: To protect combustion state from deteriorating due to accumulation of soot when the power supply stops by a method by a method wherein the air passage of the combustion chamber through the air supply and suction part is shielded when a burner fan stops.  
     CONSTITUTION: An air suction and supply part 2 is inotalled at the rear side of the case body 1 of a hot air heater and the air sucked from the air suction and supply part 2 by a burner fan 3 is sent to the combustion part 13 through an air chamber 6.

This shield plate 4 interrupts the passage by its own weight when the pressure of the air sent from the burner fan 3 does not reach a prescribed value. Therefore, since the combustion part 13 is shielded from the air and flame as soon as the power supply stops, combustion is not kept long under the state of absence of the air and since any soot does not appar and accumulate, the succeeding combustion state can be kept from deterioration.
