Boiler optimization results in maximizing thermal transfer to the water wall and convection boiler tubes while minimizing NOx and CO production. Many factors come into play, including burner location, the use of swirl, balancing local air to fuel ratios (enthalpy balance), minimizing operating O2, and the use and placement of overfire air systems, which controls the stoichiometry distribution in the furnace.
Chemistry, Physics, field experience, simulation analysis tools, and the use of NO, CO, and O2 diagnostic measurements at the economizer outlet will be covered.
