Steam Control System

Abstract

A steam control system. An illustrative embodiment of the steam control system includes a boiler, a steam outlet conduit communicating with the boiler, a steam control valve provided in the steam outlet conduit, a controller connected to the steam control valve and an outdoor temperature sensor connected to the controller.

1 . A steam control system, comprising:
 a boiler;   a steam outlet conduit communicating with said boiler;   a steam control valve provided in said steam outlet conduit;   a controller connected to said steam control valve; and   an outdoor temperature sensor connected to said controller.   
   
   
       2 . The steam control system of  claim 1  further comprising at least one room temperature sensor connected to said controller. 
   
   
       3 . The steam control system of  claim 1  further comprising a steam temperature sensor communicating with said steam outlet conduit and connected to said controller. 
   
   
       4 . The steam control system of  claim 1  further comprising a vacuum sensor communicating with said steam outlet conduit and connected to said controller. 
   
   
       5 . The steam control system of  claim 4  further comprising a vacuum sensor line connecting said vacuum sensor to said controller and a condensation return line connecting said vacuum sensor line to said boiler. 
   
   
       6 . The steam control system of  claim 5  further comprising a condensation return vacuum pump provided in said condensation return line and a vacuum pressure sensor provided in said condensation return line between said vacuum sensor line and said condensation return vacuum pump and connected to said controller. 
   
   
       7 . The steam control system of  claim 1  further comprising a variable frequency drive connected to said controller. 
   
   
       8 . A steam control system, comprising:
 a boiler;   a steam outlet conduit communicating with said boiler;   a steam control valve provided in said steam outlet conduit;   a controller connected to said steam control valve;   an outdoor temperature sensor connected to said controller;   at least one room temperature sensor connected to said controller;   a steam temperature sensor communicating with said steam outlet conduit and connected to said controller; and   a vacuum sensor communicating with said steam outlet conduit and connected to said controller.   
   
   
       9 . The steam control system of  claim 8  further comprising a vacuum sensor line connecting said vacuum sensor to said controller and a condensation return line connecting said vacuum sensor line to said boiler. 
   
   
       10 . The steam control system of  claim 9  further comprising a condensation return vacuum pump provided in said condensation return line and a vacuum pressure sensor provided in said condensation return line between said vacuum sensor line and said condensation return vacuum pump and connected to said controller. 
   
   
       11 . The steam control system of  claim 8  further comprising a variable frequency drive connected to said controller.
