Bubbling Fluidized-Bed Technology Serves Combustion

The reduced emission is due to a significantly lower primary combustion zone stoichiometry. Table 1 shows emission predictions of a typical southern U.S. wood waste-fired BFB boiler. If the boiler is regulated to a lower NOx emission level than is possible through staging combustion, then a post-combustion NOx reduction process must be added.
