A GAS STOVE HEAD ACCORDING TO THE PRESENT INVENTION COMPRISES A STOVE CASING HAVING A DISH-LIKE UPPER BODY WITH A HOLLOW CENTRAL REGION, WHEREIN THE UPPER BODY IS TILTED UPWARD FROM THE INNER EDGE PERIPHERALLY HAVING HOLES IN A POSITION BETWEEN EACH OF CONTAINER SUPPORTING STANDS. THE UPPER BODY OF THE STOVE CASING HAS CONTAINER SUPPORTING STANDS EQUALLY SPACED APART FROM EACH OTHER USED FOR PLACING A FOOD-COOKING CONTAINER. THE TOP PORTION OF LOWER BODY OF THE STOVE CASING IS A HEAT RETAINING RING HAVING A HOLLOW CYLINDER-LIKE FLAT OVERALL BODY OF WHICH A PERIPHERALLY CENTRAL REGION HAS AIR HOLES, WHEREIN. A TOP EDGE OF THE HEAT RETAINING RING HAS RIDGES PERIPHERALLY AND EQUALLY SPACED APART FROM EACH OTHER IN A POSITION BETWEEN EACH OF CONTAINER SUPPORTING STANDS TO ALLOW THE OUTSIDE AIR FLOWING THROUGH A GAP BETWEEN EACH OF RIDGES TO ACHIEVE A MORE COMPLETE BURNING PROCESS. AFTER GAS IS RELEASED FROM A GAS INJECTOR, GAS AIRFLOW IS MORE ORDERLY ARRANGED BY PROVIDING A TOP CURVED RIDGE AND A BOTTOM CURVED RIDGE LOCATED IN THE REGION INSIDE THE EXTENSION PORTION OF THE GAS SUPPLYING CHAMBER. BY DOING SO, GAS AIRFLOW WHILE PASSING THROUGH THE UPPER AND LOWER CURVED RIDGES INSIDE THE EXTENSION PORTION OF THE GAS SUPPLYING CHAMBER IS DEFINITELY SEPARATED INTO TWO DIRECTIONS AND THERE IS NO GAS FLOW LOSS SINCE GAS CAN FLOW BACK IN A CIRCLE SHAPE BY WHICH THE GAS AIRFLOW END IS DIRECTED UPWARD AND THUS GENERATING USABLE THERMAL ENERGY FOR BURNING PROCESS TWICE AS MUCH AS OF THE CONVENTIONAL GAS STOVE HEAD.
