    摘要: A solid fuel boiler with one or more fuel chutes configured to pre-dry wet solid fuel prior to loading into a combustion chamber of the boiler, enabling higher thermal efficiencies and burning less fuel to produce the same steam quantity. The pre-drying fuel chutes pass through the boiler where hot combustion gases radiantly and convectively—heat the chute walls to dry the wet solid fuel by radiant, convective, and/or conductive heating. Agitator mechanisms or structures within the chute mix the fuel for uniform heating, break up clumps of wet fuel, regulate the speed of falling fuel, prevent sticking, dry the fuel by means of steam and/or hot air, transport and deliver a cooling medium while a chute is offline in an operating boiler, and suppress fire using steam injection. Fuel from the chute can flow into a fuel storage bin or directly into the combustion zone of the furnace.

    摘要: A combustion air system for a recovery boiler is described in which multiple levels of secondary and tertiary combustion air ports each have an even number of ports, with the ports on opposing walls interlaced. The air system lends itself equally well to front/rear wall or sidewall applications and is especially beneficial for rectangular boilers. The air system features large and small-scale horizontal circulation zones superimposed on each other and the ability to adjust the angle of the air jets. Additional features include port dampers for the starting burners and system control based on kinetic energy.

    摘要: An air port damper system for a recovery boiler employs plural louvers for altering the exit angle of air through an air port. Dampers are provided to enable adjustment of the flow through the device. Suitably, the device may be retracted away from the air port, to enable manual or automatic cleaning of the port. Further the damper system can be removed for maintenance/service purposes, without requiring shut-down of the boiler.
