Abstract
This invention is directed to a method and an apparatus to heat certain particles. These certain particles are heated to make them more desirable. In the heating of these particles, it is often desirable to expand the particles to make a light-weight aggregate. The light-weight aggregate may be used in making a building material or the like. In carrying out the process of heating these particles, there is used air for combustion of the combustible fuel and only a mimimum of air for carrying of the particles or expansion of the particles.
Claims32
A furnace for heating a first subject to form a heated first subject, said furnace comprising:
- a. a first heating material having a first heating surface;
- b. a second heating material having a second heating surface;
- c. said first heating material and said second heating material being in an opposed relation and spaced apart to allow said first subject to be positioned between them;
- d. the distance between said first heating material and said second heating material may be as small as one-quarter of an inch;
- e. a bed of loose particles on said first heating surface;
- f. a first means to heat said first heating material being a means to introduce fuel to said furnace to restrict combustion of said fuel to occur above said first heating surface and below said second heating surface and in close proximity to said first heating surface to have a burning hearth;
- g. a second means to position said first subject on said bed of loose particles to be heated to form said heated first subject;
- and,
- h. a third means for removing said heated first subject from said bed of loose particles.
A furnace for heating a first subject to form a heated first subject, said furnace comprising:
- a. a first heating material having a first heating surface;
- b. a second heating material such as an intermediate plate having a second heating surface;
- c. a third heating material having a third heating surface;
- d. said third heating material and said second heating material being in an opposed relation and spaced apart to allow said first subject to be positioned between them;
- e. a first means to heat said first heating material being a means to introduce fuel to said furnace to restrict combustion of said fuel to occur above said first heating surface and below said second heating surface and in close proximity to said first heating surface to have a burning hearth;
- and,
- f. a second means to position said first subject on said second heating material to be heated to form said heated first subject.
A method for heating a first subject, said method comprising:
- a. positioning a first heating material in a substantially horizontal position;
- b. positioning a bed of loose particles on said first heating material;
- c. positioning said first subject on said bed of loose particles;
- d. positioning a fuel on said first heating material to have said fuel burn in close proximity to said first heating material to have said first heating material a hearth and in effect have a burning hearth.
A method for heating a first subject, said method comprising:
- a. positioning a first heating material in a substantially, horizontal position;
- b. positioning a second heating material on said first heating material;
- c. positioning a bed of loose particles on said second heating material;
- d. positioning said first subject on said bed of loose particles;
- and,
- e. positioning a fuel on said second heating material to have said fuel burn in close proximity to said second heating material to have said second heating material a hearth and in effect a burning hearth.
A method for heating a first subject, said method comprising:
- a. positioning a first heating material in a substantially horizontal position;
- b. positioning a second heating material in a substantially horixontal position;
- c. said second heating material being above said first heating material and spaced apart from said first heating material;
- d. positioning a fuel on said first heating material to have said fuel burn in close proximity to said first heating material to have said first heating material a hearth and in effect having a burning hearth;
- and,
- e. positioning said first subject on said second heating material.
