Abstract

Abstract An arc producing apparatus, such as a plasma-jet, for generating superheated steam; comprising, an arc chamber axially aligned with a steam chamber so that water flowing through a water jacket thereof absorbs heat from the arc and is changed into steam. The steam is conducted from the water jacket of the arc producing apparatus into the steam chamber where the steam is superheated as it flows from the interior of the steam chamber, back up into the arc chamber, and then back into and out of the steam chamber, with the steam assuming a countercurrent spiral flow path.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 235 words
Steam generation apparatus comprising a longitudinally extending metal arc chamber having opposed ends, a closure means in the form of an electrode holder at one end thereof; an electrode supportingly received by said electrode holder and having a marginal end portion thereof extending into the space enclosed by said arc chamber; means electrically insulating said electrode from said arc chamber; an annular water jacket concentrically formed about said arc chamber, a water inlet and a steam outlet spaced from one another and connected in fluid flow relationship to said water jacket; electric circuit means including an electric source of energy for causing an arc to occur between said electrode and the interior wall surface of said arc chamber, to thereby generate heat which is removed by water which may be circulating through the water jacket; a steam chamber having opposed ends spaced from one another, a closure means at one end of said steam chamber, the remaining end of said steam chamber being sealed to and in open communication with the remaining end of said arc chamber; said steam chamber having a steam inlet port and a steam outlet port, conduit means flow connecting said steam inlet port to said steam outlet; so that water flows into said water inlet, changes into steam and flows through said inlet port into said steam chamber where the steam is superheated and flows through said steam outlet port.
Claim 2
Dependent Claim 235 words
Steam generation apparatus comprising a longitudinally extending metal arc chamber having opposed ends, a closure means in the form of an electrode holder at one end thereof; an electrode supportingly received by said electrode holder and having a marginal end portion thereof extending into the space enclosed by said arc chamber; means electrically insulating said electrode from said arc chamber; an annular water jacket concentrically formed about said arc chamber, a water inlet and a steam outlet spaced from one another and connected in fluid flow relationship to said water jacket; electric circuit means including an electric source of energy for causing an arc to occur between said electrode and the interior wall surface of said arc chamber, to thereby generate heat which is removed by water which may be circulating through the water jacket; a steam chamber having opposed ends spaced from one another, a closure means at one end of said steam chamber, the remaining end of said steam chamber being sealed to and in open communication with the remaining end of said arc chamber; said steam chamber having a steam inlet port and a steam outlet port, conduit means flow connecting said steam inlet port to said steam outlet; so that water flows into said water inlet, changes into steam and flows through said inlet port into said steam chamber where the steam is superheated and flows through said steam outlet port.
Claim 3
Dependent Claim 36 words
The apparatus of claim 1 wherein said inlet port is arranged tangentially respective to the interior of the steam chamber to thereby impart a spiral flow path into the steam which flows into the steam chamber.
Claim 4
Dependent Claim 38 words
The apparatus of claim 1 wherein said arc chamber and said steam chamber are axially aligned and connected together by a throat of reduced diameter respective to the inside diameter of said arc chamber and said steam chamber.
Claim 5
Dependent Claim 39 words
The apparatus of claim 1 wherein said water jacket is made into a spiraled annulus circumferentially disposed about said arc chamber to thereby enhance the heat transfer between the arc chamber and any water flowing through said water jacket.
Claim 6
Dependent Claim 108 words
The apparatus of claim 1 and further including a throat interconnecting said arc chamber and said steam chamber, said throat having a reduced cross-sectional area relative to the cross-sectional area of the arc chamber and the steam chamber, the inlet port of said steam chamber being arRanged tangentially with respect to the inside surface thereof; the steam outlet being arranged perpendicular with respect to the longitudinal central axis of the steam and arc chamber, and; said water jacket being made into a spiraled annulus circumferentially disposed about said arc chamber to thereby enhance the heat transfer between the arc chamber and any water flowing through the water jacket.
