Definitions

  • Standard central heating systems operate by providing heated water to radiators via a circulating pump to keep the water in a user system under continous circulation.
  • Many different sources of heat can be employed to heat the circulating water, and one approach is to generate steam and heat the circulating water via a thermal converter.
  • the present invention is directed towards providing a component for use in a heating system which improves such efficiency.
  • a component for attachment, in use, to a heating system comprising:
  • the component may further comprise a second outlet connected to the diffusion region and arranged to act as a by-pass conduit in use.
  • the component may further comprise a second jet formed from an outwardly tapered frusto-conical region and a second mixing region for receiving heated water from the second jet and from a water compensation inlet, the second jet and second mixing region, together with the second water compensation inlet, being positioned between the second and third components of the mixing region.
  • a second jet formed from an outwardly tapered frusto-conical region and a second mixing region for receiving heated water from the second jet and from a water compensation inlet, the second jet and second mixing region, together with the second water compensation inlet, being positioned between the second and third components of the mixing region.
  • Each of the inlets and/or each of the outlets may be formed with a flange for ease of connection to a heating system.
  • a component according to the present invention has a first inlet 1 for receiving heated gas (preferably steam) in use, and the second inlet 2 for receiving cooled heating liquid (preferably water) in use.
  • the component also has a heated heating liquid outlet 3.
  • Each of the inlets 1, 2 and outlet 3 has a flange associated therewith for attachment, in use, to pipe work associated with the heating system to which the component is connected.
  • the component has a main body 4 which connects the two inlets 1, 2 to the outlet 3.
  • a frusto-conical inlet nozzle 5 Positioned for receiving gas from the inlet 1 is a frusto-conical inlet nozzle 5 which tapers initially from inlet 1 inward, and then has a flared jet nozzle 6 at the end furthest from the receiving entrance of the inlet 1.
  • This nozzle 6 projects, in use, gas into a mixing chamber 7, which again has a tapering frusto-conical region, followed by a circular chamber mixing region 8 and a diffusion region nine which is also frusto-conical in configuration and tapers outwardly toward the outlet 3.
  • the component receives cooled liquid which has passed through the heating system (not shown) from the inlet 2, and this surrounds the inlet nozzle configuration 5, 6, mixing with it to produce a heated liquid output at the outlet 3.
  • the component operates by compressing input gas in the nozzle 5, 6, such that it exits the tip 6 at high (possibly supersonic) speed. After exiting the nozzle 5, 6, the pressure in the steam is reduced generating a negative pressure differential and allowing rapid and reliable exchange of heat and momentum between the heated gas and the cooled liquid.
  • the configuration of the mixing chamber 7 and mixing region 8 is such that exchange of heat and momentum from the gas to the cooled liquid occurs in a generally uniform manner and the dimensions of these regions can be controlled to ensure appropriate mixing at pressure and temperatures suitable for the system to which the component is to be connected.
  • the diffusion region 9 allows the flow of the combined gas and liquid (which is now a heated liquid) to reduce gradually whilst the pressure increases and is configured as such that heated liquid with a known pressure and temperature can be obtained at the outlet 3.
  • the present invention makes use of both heat and kinetic energy in the gas, not only to produce appropriate heating, but also to enable a degree of self-circulation such that in some circumstances additional pumping apparatus will not be required in the system, or at the very least the pumping requirements will be reduced considerably, again improving energy efficiency of the system as a whole.
  • FIG. 2 shows a second example of the present invention, in which an additional outlet 10 is provided with a connection 11 to the diffusion region 9.
  • the component operates in a manner very similar to that shown in figure 1, and corresponding components are numbered identically.
  • This additional outlet 10 is provided to enable an override of the system should operating pressures be exceeded, both as a safety restriction and to control the overall operation of the system in which the component is employed in use. By attachment of outlet 10 to a relief valve heated liquid can be removed from the system if necessary.
  • FIG. 3 shows a further example, again in which components which operate in a similar manner to those in figures 1 and 2 are numbered identically.
  • a second jet 13 is provided following the mixing chamber 7.
  • the second jet 13 exits into a region 14 into which additional water can be provided via a third inlet 12 connected between the second jet 13 and second mixing chamber prior to having the necessary flow and pressure compensation performed thereon by regions 8, 9, prior to exiting of heated liquid via the outlet 3.
  • This enables the addition of further liquid into the system to compensate for liquid losses in the system, and also to regulate the overall temperature of the liquid output via the inlet 12.
