    Abstract: A cylindrical furnace having a vertical axis advantageously controls the combustion. Solid fuel, particulates, and gases are present inside the furnace and rotate around the axis of the cylinder to induce the solid particles and gases to stratify radially due to centrifugal force. Fuel and particulates at the perimeter slip in and out of suspension as they drag on the wall of the cylinder. This increases the residence time of the particles in the furnace. The solid particles are composed of combustible fuel particles, non-combustible ash, and non-combustible contaminants that enter with the fuel. It is necessary to control the temperature of the non-combustible particles and the wall surface to prevent non-combustible particles from adhering to and building up on the furnace wall. It is also advantageous to control the gas temperature leaving the furnace to minimize temperature driven corrosion of downstream heat exchanging surfaces. Method and apparatuses are described to control the gas, non-combustible particle, and wall temperatures within the cylindrical furnace. The furnace can be integrated into a stand-alone boiler or as a combustor in which a portion of the pyrolysis gas from the combusting fuel is burned in a separate vessel.

    Abstract: A ground supported power boiler is described combining a refractory lined and insulated conical floor; an insulated cylindrical combustion chamber; a cylindrical furnace with water tube wall; a rectangular convective section; a single vertical steam drum; tangential injection of the fuel and combustion air; means for fluidizing the fuel bed; means for selectively stripping particulates from the flue gases; multi-stage particulate stripping and filtering from flue gases, means for using the walls of steam drum as steam/water droplet separator, means for recirculating and capturing heat from the flue gases; means for pressurizing the interior of the boiler above atmospheric pressure; means for heating and drying fuel prior to feeding the fuel to the boiler; means for creating hydrogen shift reaction; means for eliminating any need for sootblowing; and designed to not require the use of an induced draft fan.

    Abstract: 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.

    Abstract: 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.
