The present disclosure describes about a free flowing sodium nitrite and a method (200) of obtaining the free flowing for sodium nitrite. The method (200) may comprise various steps such as optimizing (202) the concentration of SNI, heating (206) of sodium nitrite slurry at 50 to 600 rpm, gradually cooling (208) the heated mass below 45° C., filtering (210) the wet mass, drying a filtered mass (212), and sieving (214) the dried mass to obtain the free flowing sodium nitrite comprising a spherical or oval shape granules. The spherical or oval shaped granules of SNI obtained has a moisture content of less than 0.15%, mesh size of more than 60 BSS in an amount 60-80% of the total content the particle size of at least 0.25 mm in an amount 60-80% of the total content, angle of repose between 25° to 37° and Hausner ratio of 1.03 to 1.17.

Disclosed is a venturi air-ammonia mixer 200 enabled for a two-burner system. The venturi air-ammonia mixer 200 comprises a venturi body 204 and an annular region 212. Further the venturi body 204 comprises a convergent section 204(a) comprising an air inlet feed 208 a cylindrical section 204(b) comprising an inner hollow member 202, and a divergent section 204(c) comprising an air-ammonia gas outlet 210. Further the cylindrical section 204(b) and the inner hollow member 202 comprises a first perforated region and a second perforated region. Further the cylindrical section 204(b) is enclosed in the annular region 212 and connected to an ammonia inlet feed 206. Further the ammonia inlet feed 206 fills the annular region 212 with dry ammonia gas which further flows into the venturi air-ammonia mixer 200 through the perforated regions thereby enabling uniform mixing of the ammonia gas with air from the air inlet feed 208.
