The method described herein can create a fire from burning solid biomass that reduces the amount of smoke and harmful gas emissions (e.g., carbon monoxide), increases output power, and improves the combustion of the briquettes used as a solid fuel in a cooking apparatus (e.g., a cooking stove). ## Claims ### Claim 1 A method for burning biomass briquettes, comprising: a) providing two or more biomass briquettes, wherein each biomass briquette has two main faces and one or more side faces; b) arranging the two or more biomass briquettes in one or more rows to increase heat exchange between adjacent biomass briquettes in each row, wherein each biomass briquette is placed on a side face so that a main face of one biomass briquette faces a main face of an adjacent biomass briquette in each row, wherein a space exists between the main faces of adjacent biomass briquettes in each row, and wherein the space between the main faces of adjacent biomass briquettes in each row is between 1 mm and 50 mm; c) igniting at least one biomass briquette; and d) creating a fire from burning of the two or more biomass briquettes. ### Claim 2 (depends on 1) The method of claim 1, wherein the two or more biomass briquettes are cylindrical briquettes, wherein the cylindrical briquettes have two main faces and one side face. ### Claim 3 (depends on 1) The method of claim 1, wherein the two or more biomass briquettes are rectangular briquettes, wherein the rectangular briquettes have two main faces and four side faces. ### Claim 4 (depends on 1) The method of claim 1, wherein each biomass briquette independently has a density of less than 0.6 g/cm3. ### Claim 5 (depends on 4) The method of claim 4, wherein each biomass briquette independently has a density between 0.1 g/cm3 and 0.5 g/cm3. ### Claim 6 (depends on 5) The method of claim 5, wherein each biomass briquette has a density of about 0.3 g/cm3. ### Claim 7 (depends on 1) The method of claim 1, wherein the space between adjacent biomass briquettes is between 5 mm and 30 mm. ### Claim 8 (depends on 1) The method of claim 1, wherein each biomass briquette independently comprises urban waste, agricultural waste, or a combination thereof. ### Claim 9 (depends on 8) The method of claim 8, wherein the urban waste comprises paper, cardboard, sawdust, or a combination thereof. ### Claim 10 (depends on 8) The method of claim 8, wherein the agricultural waste comprises animal processing waste, cellulosic materials, or a combination thereof. ### Claim 11 (depends on 1) The method of claim 1, wherein the fire has a temperature of at least 500° C. ### Claim 12 A cooking apparatus, comprising: a combustion chamber; an air inlet, wherein the air inlet controls the flow of air into the combustion chamber; a briquette platform, wherein the briquette platform is located inside the combustion chamber configured to receive two or more biomass briquettes, wherein the two or more biomass briquettes are arranged on the briquette platform in one or more rows to increase heat exchange between adjacent biomass briquettes in each row, wherein each biomass briquette has two main faces and one or more side faces, wherein each biomass briquette is placed on a side face so that a main face of one biomass briquette faces a main face of an adjacent biomass briquette in each row, wherein a space exists between the main faces of adjacent biomass briquettes in each row, and wherein the space between the main faces of adjacent biomass briquettes in each row is between 1 mm and 50 mm; and a cooking housing, wherein the cooking housing sits above the combustion chamber. ### Claim 13 (depends on 12) The apparatus of claim 12, wherein the briquette platform comprises one or more holes to control airflow. ### Claim 14 (depends on 12) The apparatus of claim 12, wherein the space between adjacent biomass briquettes on the briquette platform is between 5 mm and 30 mm. ### Claim 15 (depends on 12) The apparatus of claim 12, further comprising a briquette tray, wherein the briquette tray is placed on top of the briquette platform inside the combustion chamber, and wherein the two or more biomass briquettes are arranged on the briquette tray. ### Claim 16 (depends on 12) The apparatus of claim 12, wherein the cooking housing is configured to receive a cooking utensil selected from the group consisting of a cooking plate, a grill, a pot, a wok, and a Dutch oven. ### Claim 17 (depends on 12) The apparatus of claim 12, wherein the temperature inside the combustion chamber is at least 500° C. ### Claim 18 (depends on 12) The apparatus of claim 12, wherein the two or more biomass briquettes comprise urban waste, agricultural waste, or a combination thereof. ### Claim 19 (depends on 18) The apparatus of claim 18, wherein the urban waste comprises paper, cardboard, sawdust, or a combination thereof. ### Claim 20 (depends on 18) The apparatus of claim 18, wherein the agricultural waste comprises animal processing waste, cellulosic materials, or a combination thereof.
