Fuel

Abstract

The invention relates to a fuel having an additive for increasing the calorific value, wherein the additive hardens and the handling of the fuel is thereby improved.

1 . A fuel comprising a starting material with a first additive, characterised in that the additive comprises 50 to 60% palmitic acid, 40 to 50% stearic acid, maximum 1% lauric acid, maximum 3% myristic acid and traces of oleic acid. 
   
   
       2 . The fuel according to  claim 1  further comprising a second additive comprised of paraffin. 
   
   
       3 . The fuel according to  claim 2 , the first and second additives each defining a fraction, the maximum fraction of the second additive being as large as the fraction of the first additive. 
   
   
       4 . The fuel according to  claim 1 , the starting material being in shaped pieces. 
   
   
       5 . The fuel according to  claim 1 , the starting material being selected from the group of coal, biomass or a mixture thereof. 
   
   
       6 . A method for producing a fuel comprising the following steps:
 a) producing a starting material,   b) adding an additive comprised of 50 to 60% palmitic acid, 40 to 50% stearic acid, maximum 1% lauric acid, maximum 3% myristic acid and traces of oleic acid, and   c) pressing the fuel into a particular shape.   
   
   
       7 . The method according to  claim 6 , wherein the additive is heated to at least its specific melting point. 
   
   
       8 . The method according to  claim 6  further comprising adding another additive comprised of paraffin. 
   
   
       9 . The method according to  claim 6 , wherein the fuel is pressed before adding the additive. 
   
   
       10 . The method according to  claim 6 , wherein the fuel is pressed after adding the additive. 
   
   
       11 . A method for producing a fuel comprising the following steps:
 a) producing a starting material,   b) adding an additive comprised of parrafin, and   c) pressing the fuel into a particular shape.   
   
   
       12 . The method according to  claim 11 , wherein the additive is heated to at least its specific melting point. 
   
   
       13 . The method according to  claim 11 , wherein the fuel is pressed before adding the additive. 
   
   
       14 . The method according to  claim 11 , wherein the fuel is pressed after adding the additive. 
   
   
       15 . The fuel according to  claim 2 , the starting material being in shaped pieces. 
   
   
       16 . The fuel according to  claim 15 , the starting material being selected from the group of coal, biomass or a mixture thereof. 
   
   
       17 . The fuel according to  claim 2 , the starting material being selected from the group of coal, biomass or a mixture thereof. 
   
   
       18 . The fuel according to  claim 4 , the starting material being selected from the group of coal, biomass or a mixture thereof.
