Claim 1:

Functional features in a horizontal furnace to produce hot air or gas from simultaneously cooling the hot atomized slag or any other hot solid material introduced into the furnace; exchange the produced hot air or gas to produce energy and to simultaneously cool the produced hot air or gas; mainly comprising: a) a floor (003) with plurality passages;

b) the floor (003) is disposed over a plenum (006) and the floor (003) move along the horizontal axis towards the cooled atomized slag exit (007e) and the cooled air or gas exit (007m); c) a means (007a) to introduce ambient cooled atomized slag (008) into the furnace chamber space (002) and spread a layer on the moving floor (003);

d) the introduced ambient cooled atomized slag (008) is a portion of its corresponding hot atomized slag that was post-cooled in the furnace (001), but which is further cooled to ambient temperature, cleaned and processed outside the furnace (001);

e) any introduced ambient cooled hot solid material other than the ambient cooled atomized slag (008) is a portion of its corresponding hot solid material that was post-cooled in the furnace (001), but which is further cooled to ambient temperature, cleaned and processed outside the furnace (001);

f) the means (007e) to introduce ambient cooled atomized slag (008) is disposed behind the falling hot atomized slag (017b) that fall above the moving surface of the ambient cooled atomized slag layer (008) and spread a layer above the moving surface of the ambient cooled atomized slag layer (008);

g) the ambient air or gas that is injected into the plenum (006) via means (016) flow through the plurality passages in the moving floor (003), then through the layer of the ambient cooled atomized slag (008), and then through the layer of the cooling atomized slag (017b) to further cool the layer of the cooling atomized slag (017b) and produce hot air or gas updraft flow into the furnace chamber space (002) above the moving surface of the cooling atomized slag layer (017b);

h) the heated updraft air or gas is made to flow along the horizontal axis in the moving direction of the floor (003) above the moving surface of the cooling atomized slag layer (017b) in the furnace chamber space (002);

i) the hot air or gas updraft interface with the hot air or gas that is made to flow along the horizontal axis and their mixture flow above the moving surface of the cooling atomized slag layer (017b) along the horizontal axis in the furnace chamber space (002) until such cooling atomized slag layer (017b) falls from the floor (003) to exit the furnace (001) from (007e); j) heat is recovered from the produced hot air or gas to produce energy and the air or gas is simultaneously cooled during its flow along the horizontal axis in the furnace chamber (002) and during its flow beyond the point in the furnace chamber space (002) where the floor (003) ends above the cooled atomized slag exit (007e) and before the cooled air or gas exit the furnace (001) from (007m).

Claim 2:

Functional features in the horizontal furnace (001) in accordance to claim 1 to produce hot air or gas from simultaneously cooling the hot atomized slag or any other hot solid materials introduced into the furnace; exchange the produced hot air or gas to produce energy and to simultaneously cool the produced hot air or gas; further comprising:

1 a) a means (007b) to introduce solid carbonaceous material (009) into the furnace chamber space (002) and spread a layer above the moving surface of the ambient cooled atomized slag layer (008) but before the hot automized slag fall (017b);

b) ambient air or gas is blown by a means (010) across the falling hot automized slag (017b) to cool the falling hot atomized slag (017b) and to heat such blown ambient air or gas;

c) the heated air or gas is made to flow along the horizontal axis in the moving direction of the floor (003) in the furnace chamber space (002);

d) plurality gas or plasma torches (020) communicate additional heat and gas along the horizontal axis into the furnace chamber (002) after the hot atomized slag fall (017b);

e) the plurality gas or plasma torches (020) are disposed above the moving surface of the cooling atomized slag layer (017b);

f) a means (007f) to introduce additional carbonaceous materials into the furnace chamber space (002) along the horizontal axis after the hot atomized slag fall (017b);

g) the means (007f) to introduce additional carbonaceous materials into the furnace chamber space (002) is disposed before the plurality gas or plasma torches (020) and above the moving surface of the cooling atomized slag layer (017b);

h) a means (007g) to introduce catalyst or carbonaceous materials into the furnace chamber space (002) and make it move counter current to the flow of the cooling air or gas and a means (007h) to remove such catalyst or carbonaceous materials from the furnace (001).

Claim 3:

Functional features in the horizontal furnace (001) in accordance to claim 1 and claim 2 to produce hot air or gas from simultaneously cooling the hot atomized slag or any other hot solid materials which is introduced into the furnace chamber space (002) in the form of molten liquid (012) and is atomized inside the furnace chamber space (002); exchange the produced hot air or gas to produce energy and to simultaneously cool the produced hot air or gas; further comprising: a) a molten liquid (012) reservoir (019) with a molten liquid (012) outlet (018) which

communicates the molten liquid (012) into the furnace chamber space (002) via a means (007d);

b) a means (013) to atomize the received molten liquid slag (012) and make it fall inside the furnace chamber space (002).
