Abstract
A low NO.sub.x, integrated boiler-burner cogeneration apparatus includes a horizontally fired, factory assembled package boiler having an inlet plenum and a furnace space. A gas turbine-generator having an outlet for providing turbine exhaust gas to the furnace space is connected to the boiler. A multi-nozzle burner (MNB) array including a plurality of vertically and horizontally spaced burner nozzles is located at an entrance to the furnace space for supplying fuel for combustion into the furnace space while distributing the heat of the combustion exhaust gases across the furnace space to minimize NO.sub.x formation. One or more chill tube assemblies are located within the furnace space immediately downstream of the MNB array for rapidly reducing the temperature of the combustion exhaust gases. Laterally perforated internal duct assemblies can also be provided within the furnace space, alone or in combination with the chill tube assemblies in various arrangements to provide staging gases for completing combustion in the furnace space. A forced draft fan supplies combustion air alone or in combination with the turbine exhaust gases through the MNB array to mix with the fuel provided by the burner nozzles and produce the combustion flame.
