摘要： The present invention concerns a CLC method and plant for a hydrocarbon feedstock, comprising combustion of said hydrocarbon feedstock (8) on contact with an oxygen carrier in form of particles in a reduction zone (R0), and oxidation of the oxygen carrier from reduction zone (R0) on contact with an oxidizing gas, preferably air, in an oxidation zone. According to the invention, gaseous oxygen is released by the oxygen carrier in a sealing device (S1) operating in a dual fluidized bed and positioned in the path of said carrier from the oxidation zone to the combustion zone, and it is mixed with part of the combustion fumes intended to be recycled to the reduction zone. The gaseous oxygen then enables combustion of the residual unburned species that may be contained in the combustion fumes and/or it participates in the combustion of the hydrocarbon feedstock in the reduction zone.

摘要： A method for the combustion of ammonia, wherein a first combustion chamber (2) receives ammonia (4) and hydrogen (5) in controlled proportions, and an oxygen-containing gas. Combustion of the ammonia and hydrogen produces NH2− ions among other combustion products (22). A second combustion chamber (3) receives the combustion products (22) from the first combustion chamber and receives further ammonia (4) and further hydrogen (5) in controlled proportions, wherein combustion produces nitrogen oxides among other combustion products (24). A third combustion chamber (14) receives the nitrogen oxides along with further ammonia and further hydrogen in further controlled proportions along with further oxygen-containing gas, such that the nitrogen oxides are combusted into nitrogen and water.

摘要： An improved burner assembly and process for operating same using a burner design that produces very low levels of undesirable nitrogen oxides is provided. The burner assembly premixes primary fuel and air in a venturi system and recirculates combustion gases back to the burner through a plurality of recirculation conduits where it is mixed with the premix of fuel and air and secondary air prior to combustion in a primary combustion zone. Rapid premixing of the primary fuel and air in the venturi system and the dispersion of the recirculated furnace gases is believed to result in lower peak flame temperatures and therefore minimizing the formation of the pollutants, such as nitrogen oxides.
