Patent JP-H02272205-A (JP)
Title: Boiler device
Inventor: ISHII KYUMA
IPC: F22D1/12
Filed: 1989-12-19
Abstract: PURPOSE:To prevent the low temperature corrosion of economizer without using feed water heater, heating deaerator, etc., by simply adding a feed water bypass line and a recirculation line to the main feed water pipe. CONSTITUTION:A feed water recirculation line 10 having a manual regulator valve therein is disposed between the point 10b in the economizer outgoing line 3b and the point 10a in the line which is connected to a feed water temperature regulating valve 12 and a recirculation pump 11 so as to recirculate while in operation a nearly constant quantity of feed water leaving from the economizer 7. Although the outgoing feed water temperature from the economizer 7 changes according to the boiler load, the fuel economizer incoming feed water temperature maintains a predetermined temperature at which the low temperature corrosion can be prevented on account of the operation of the feed water temperature regulating valve 12 which is controlled by the command from the feed water temperature regulator 17. In order to control the incoming feed water temperature to the economizer 7, the feed water supplied from the feed water regulating valve 12 passes through the economizer 7 and performs confluence at the point 8b in the line 3b with feed water from a line 8 which bypasses the economizer 7, said feed water is supplied to the upper body shell 1a of the boiler.

Title: Traveling speed regulator of automatic traveling machine in pipe line
Inventor: TAKATSUKA KIYOSHI
IPC: B61B13/10
Filed: 1994-12-14
Abstract: PURPOSE: To provide an automatic traveling machine in a pipe line with efficient traveling speed for enabling the shortening of a traveling time by regulating in sequence the expansible and contractible action of an automatic traveling machine in a pipe line to set the action interval time on the basis of the traveling distance information from a measuring instrument in a time setting circuit. CONSTITUTION: A traveling sequence 15 for regulating an interval time between respective actions in one cycle of the expansible and contractible action of an automatic traveling machine in a pipe line is built in a controller in the same way as the conventional one. Further, the action interval time is set by a time setting circuit 16 on the basis of the traveling distance information from a measuring instrument 13. The respective action interval times a, b, c, and d of the respective actions are set to V1 , V2 , V3 modes for example. The V1 mode for a near distance region shortens the expansible action interval time b1 and contractible action interval time d1 of an air cylinder device, the V2 mode elongates somewhat respective action interval times b2 , d2 similarly and the mode V3 provides the longest action interval times b3 , d3 .  As a result, a traveling time for reaching a destination is substantially shortened.
