Steam Generating System (Patent No: 344964)

Inventor: Feguenne, Pierre

Location: Edmonton

Comments: N/A

Description: What we claim is.-

1. A steam generating system including a steam header, tubes leading therefrom, a water reservoir adjacent said tubes, means for connecting the bottom of said reservoir to the said tubes, means connecting the top of said reservoir to said header. supply means communicating with the bottom of said reservoir for supplying water to said reservoir at a pressure greater than the normal pressure within the lower portion of said reservoir, a counterweight, a valve for closing said supply means and normally held in closed position by the counterweight, and means within said reservoir operable to positively move said valve to open, position against such pressure within the supply means when the water level in the reservoir falls below a predetermined point.

2. A steam generating system including a steam header, tubes leading therefrom, a water reservoir adjacent said tubes, means connecting the bottom of said reservoir to said tubes, means connecting the top of said reservoir to said header, water supply means extending downwardly from the bottom of said reservoir for supplying water to said reservoir at a pressure greater than t he normal pressure within the lower portion of said reservoir, said supply means being formed with a valve seat therein below said reservoir; a valve normally adapted to be forced against said seat by the pressure of the water in said supply means to close said supply means and prevent entry of water into the reservoir, and means controlled by the level of the water in the reservoir and having a part extending downwardly into said supply means for positively forcing said valve from its seat against the water pressure in the supply means when the water in the reservoir falls below a predetermined level.

3. A high pressure steam generating system including a steam header, tubes leading therefrom, a water reservoir adjacent said tubes, means connecting the bottom of said reservoir to said tubes, means connecting the top of said reservoir to said header, water supply means extending downwardly from the bottom of said reservoir for supplying water to said reservoir at a pressure greater than the normal pressure within the lower portion of said reservoir, said supply means being formed with a valve seat therein below said reservoir, a counterweight, a valve normally adapted to be forced against said valve seat by counterweight, means and prevent entry of water into the reservoir, a receptacle within said reservoir having an opening therein at the top thereof, said receptacle having a part projecting into said opening to contact said valve, and means for counterbalancing said receptacle to such an extent that it will float when filled with water, whereby said receptacle will normally float in said reservoir when the receptacle is filled with water and the reservoir is filled to a predetermined level, but whereby when the water level in the reservoir falls below such predetermined level the weight of the receptacle plus the weight of the water therein will be great enough to open said valve against the pressure of the water in the supply means.

4. A low pressure steam generating system including a steam header, tubes leading therefrom, a water reservoir adjacent said tubes, means connecting the bottom of said reservoir to said tubes, means connecting the top of said reservoir to said header, water supply means extending downwardly from the bottom of said reservoir for supplying water to said reservoir at a pressure greater than the normal pressure within the lower portion of said reservoir, said supply means being formed with a valve seat therein below said reservoir, a valve normally adapted to be forced against said valve seat by the pressure of the water in said supply means to close said supply means and prevent entry of water into the reservoir, and a float within said reservoir; said float having a part extending into said supply means to contact said valve and said float being of sufficient weight to open said valve against the pressure; of the water in the supply means when the water level in the reservoir falls below a predetermined point.
