1. A venturi air ammonia mixer enabled for a double adiabatic oxidation burners system, comprising:
a venturi body comprising a convergent section (204a), a cylindrical section (204b), and a divergent section (204c), the cylindrical section (204b) being connected to the convergent section (204a) and the divergent section (204c);
wherein the convergent section (204a) comprises an air inlet feed (208) adapted to supply dry air to the cylindrical section (204b);
wherein the cylindrical section (204b) is enclosed within an annular region (212) connected to an ammonia inlet feed (206), wherein the ammonia inlet feed (206) is adapted to fill the annular region (212) with dry ammonia gas, wherein the cylindrical section (204b) further comprises an inner hollow member (202) having one end connected to the annular region (212) and positioned opposite to the ammonia inlet feed (206), wherein the cylindrical section 204(b) and the inner hollow member (202) is provisioned with a first perforated region (402a) and a second perforated region (402b), respectively, on the lateral circumference thereof in a manner such that the dry ammonia gas filled within the annular region (212) is adapted to enter the cylindrical section (204b) through the first perforated region (402a) and the second perforated region (402b) in order to facilitate uniform mixing of the dry ammonia gas with air to form air-ammonia mixture; and
wherein the divergent section (204c) comprises an outlet (210) configured to transmit the air-ammonia mixture to the double adiabatic oxidation burners (124A and 124B).
