Abstract

A steam generator comprises a container 1 having a water inlet pipe and a steam outlet pipe 11. A number of heat sources 4, 5, 6 are located in the top and bottom of the container. The container has a number of self sealing spring loaded moving walls 2, 3. Water 19 inside the container is heated by the heat sources, increasing water pressure and forcing the walls to compress against end stops 12, 13. This increase the volume of the container which fills with steam 20 evaporated from the water. Heat source 4 continues to heat the water, and heat sources 5, 6 now supply heat to the steam to provide superheated steam. Opening steam valve 21 reduces the pressure inside the container causing the remainder of the water to evaporate to steam, which is turned into superheated steam by heat sources 5, 6. A plurality of steam generators may be connected together, steam from one being used to activate an automatic water filling cylinder of another.

Description

DESCRIPTION:

Advanced Steam Injector This invention relates to a method for creating and deploying superheated steam.

When heating water inside an open container the water creates steam. However, heating water does not create steam when the container is sealed closed and as a direct result no superheated steam can be created either.

To overcome this problem the present invention uses a container capable of expanding its volume allowing steam to be created inside the expanded volume. This way the steam inside the expanded volume can be heated further inside the sealed container creating superheated steam.

The invention will now be described solely by way of example giving reference to accompanying drawings: The invention can be seen as shown in the figures 1, 2,3.

Figure 1. Shows side view inside the main container body before heat is applied Figure 2. Shows side view inside the main container body after heat has been applied for a length of time Figure 3. Shows top view of the automatic water injector attached to the main container Figure 4. Shows a number of advanced steam injectors and how the automatic water injector pilot pipes are connected together Figure 1. Shows a container 1 with two movable walls 2, 3 which seal the container. The two walls 2,3 are spring loaded using springs 7, 8 shown in their maximum extension against end stop 9, 10. Inside the container are a number of heat sources 4,5, 6 and a superheated steam output 11.

Figure 2. Shows the same container 1 with two movable walls 2, 3 which seal the container. The two walls 2,3 are spring loaded shown in their maximum compression against end stop 12, 13.

Figure 3. Shows container 1 with an automatic water input cylinder attached 14 and a pilot pipe 18 attached. Attached to the water input cylinder is water input pipe 15 and pilot pipes 16, 17.

Figure 4. Shows a number of containers and how the pilot pipes are connected from container 100 to container 1 and from container ito container 200.

The following applies to figures 1, 2.

The system works by supplying water 19 to the container 1, once water 19 has filled inside container 1 heat source 4, 5,6 supply heat to water 19. Once water 19 is heated over time, pressure begins to increase inside container 1 forcing the two walls 2,3 to compress over time against end stops 12, 13.

The two walls 2,3 in full compression causes container ito increase its volume, this increase in volume allows steam 20 to build up inside container 1. Heat source 4 continues to supply heat to water 19 at the same time heat source 5, 6 are now supplying heat to steam 20. Over time the supplied heat source 4,5 will cause steam 20 to turn into superheated steam and the pressure will increase further.

Once the desired pressure is achieved superheated steam 20 is let out of container 1 through valve 21.

Whilst the superheated steam is leaving container 1 via valve 21 the pressure in container 1 will fall; as the pressure falls water 19 instantly turns to steam, at the same time extra power to heat source 4 is applied to heat water 19 in order to turn water 19 into steam 20 faster, at the same time more power to heat source 5, 5 is applied turning the extra steam into superheated steam faster before leaving container 1 via valve 21. This gives a continuous flow of superheated steam out of the container 1 for a longer time period until all of water 19 has completely vaporised into steam 20.

The following applies to figures 3,4.

The automatic water injector works by using a pilot piping the steam from container 100 which is the same as that in figure 1.

Cylinder 14 is spring loaded to full extension, in doing so the cylinder fills with water 19 via pipe 15. Pilot 16 is supplied with steam via container 100 which is in its heating process, when container 100 heats the water to temperature it will supply steam through pipe 16 to cylinder 14 via valve 24. Valve 25 closes and the steam from pipe 16 will force piston 23 to compress spring 22 and in doing so forces water 19 into container 1. At this stage piston 23 and spring 22 are in full compression. Valve 26 closes, valve 25 opens and spring 22 forces piston 23 to full extension at the same time valve 24 changes from pilot 16 to pilot 17 pushing the steam from cylinder 14 to the steam exhaust which is at low pressure. Pilot 18 supplies steam to cylinder 214 on container 200 the same as pilot 16 in figure 3.
