FIELD OF THE INVENTION [0001] The invention pertains to superheated vapor generators and systems for delivering highly superheated vapor flows as well as methods of fabrication and use of such superheated vapor generators and systems for providing desired flows of highly superheated vapor including substantially continuous flows. DESCRIPTION OF THE PRIOR ART [0002] Prior patents include U.S. Pat No. 6,006,009 (the '009 Patent), U.S. Pat. No. 5,471,556 (the '556 Patent) and U.S. Pat. No. 4,414,037 (the '037 Patent) owned by the inventor and applicant herein, co-pending U.S. patent application Ser. No. 08/484,019 owned by the applicant and inventor herein for Superheated Vapor Generator and Control System and Method, all incorporated by reference herein, references cited in connection with aforesaid U.S. Pat. No. 4,414,037 including U.S. Pat. Nos. 2,505,656; 2,753,212; 2,861,838; 2,983,450; 3,039,454; 3,218,741; 3,718,805 and 3,721,802 and patents cited in connection with said U.S. Pat. No. 5,471,556 including U.S. Pat. Nos. 377,228; 2,652,645; 3,436,852; 3,119,004; 3,869,815; 4,255,646; 3,508,354; 3,823,497; and 2,576,976. [0003] The aforesaid references in the main refer to apparatus and methods for generating steam from liquid drawn from a reservoir. [0004] The '037 Patent discloses apparatus for generating superheated steam or other vapor from liquid drawn from a self-contained reservoir and includes means in the form of a nozzle for directing superheated steam or other vapor to desired locations. The '556 Patent discloses improvements relative to the '037 Patent. Said co-pending application discloses further improvements. [0005] Equipment disclosed in the aforesaid patents and co-pending application is employable for effecting, among other things, cleaning and/or sterilization. This apparatus has proved highly useful for such purposes. In operation, such equipment provides flows of superheated vapor upon activation of a control member. [0006] The vapor stream issues, in particular applications, from either a port mounted on the generator or from a wand/extender whereby distance of the transported vapor may be extended to one hundred feet or more. Of course, there is an unavoidable loss of pressure and exit temperature in such apparatus employing extenders for transporting the superheated vapor over appreciable distances. [0007] Advantages of transporting superheated high pressure vapor with high heat are particularly apparent in applications such as sterilizing narrow or relatively inaccessible sites such as air conditioning and heating ducts, destroying and removing mold from surfaces which may be small or relatively inaccessible, among many others. [0008] Further advantages of such extended transportation of superheated vapor at high pressure are in the capability to sterilize or clean areas which require use of explosion proof equipment in their vicinity, whereby the controls and electrical aspects of the system are substantially removed from the sensitive regions. [0009] In addition, regardless of the distance of transport of superheated vapor, there are numerous benefits and advantages in connection with even further increasing temperatures of the superheated vapor from those provided by existing systems. Some of these advantages include the final product, i.e., superheated vapor, even further removal of moisture content and correspondingly greater proportion of vapor as opposed to liquid. This provides a greater capability of delivering extreme heat and temperature to selected targets as for example regions for soldering or welding, with relative security against explosion. [0010] Accordingly, there has been a felt but unfulfilled need for systems and methods for increasing the temperature and pressure of superheated vapor issuing from superheated vapor generators for the purpose of increasing efficiency and delivery of such vapor at varying distances from the source of the vapor. SUMMARY OF THE INVENTION [0011] A system and method for further heating superheated vapor comprises means connectable to superheated vapor generator apparatus for receiving and disseminating superheated vapor and for further heating said superheated vapor prior to dissemination and comprises the steps of producing superheated vapor, circulating said superheated vapor for dissemination and further heating prior to issuance of said superheated vapor.
