ALBERT FONC OF BUDAPEST, AUSTRIA-HUNGARY.
APPARATUS FOR BLOWING OFF BOILER-MUD.
Specification of Letters Patent.
Application filed February 10, 1911.
Patented Sept. 26, 1911. Serial No. 607,774.
To all whom it may concern:
Be it known that I, ALBERT FoN, a subject of the King of Hungary, residing at 17 Bathorz-utcza, Budapest in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Apparatus for Blowing Off Boiler-Mud, of which the following is a specification.
The blowing-oft of boiler mud or slime at full working pressure is ordinarily a cause of harmful shocks to the boiler.
The present invention has for its object an apparatus which permits of blowing-01f the boiler slime at full working pressure without causing such shocks. In order to produce this result, a chamber is inserted in the blow-off pipe in which chamber a somewhat lower pressure than boiler pressure is maintained and which is connected with the boiler itself by means of a flexible conduit which does not transmit the shocks as will hereinafter appear.
' An embodiment of the invention is illustrated diagrammatically in the accompanying drawing.
The blow-off pipe a proceeds from the boiler b and can be shut off by a cock 0. A yielding pipe d which does not transmit shocks is fitted to the pipe a or directly to the boiler and connects the boiler with a chamber 6. In this chamber a pressure somewhat lower than the boiler pressure (say one-tenth of an atmosphere lower) is maintained for example by a throttle valve g be ing inserted in a pipe f proceeding from the steam chamber of the boiler, this valve throttling to the desired extent the steam introduced into the chamber e. The blow-01f pipe is continued by the pipe h. In the chamber 6 the water level is maintained constant in order to avoid the direct discharge of live steam; thereby keeping the diflerence of pressure between the boiler b and the chamber 6 constant. The fall of pressure between the boiler 72 and the chamber e is so small that it cannot cause any shock to the boiler. The chamber 6 experiences the shocks.
What I claim and desire to secure by Letters Patent of the United States is Apparatus for blowing-ofi' boiler mud or slime at full working pressure characterized by the fact that a chamber 6 is inserted in the blow-off pipe in which chamber a pressure somewhat lower than the boiler pressure is maintained and which is connected with the boiler by means of a yielding pipe 03.
In testimony whereof I aflix my signature in presence of two witnesses.
ALBERT FONO. Witnesses:
