Abstract:
A method of introducing oxygen into a boiler system for combustion with a prepared fuel in a furnace combustion chamber comprises providing a plurality of swirl-inducing elements to the air stream delivery lines, and a plurality of oxygen delivery jets adjacent the intake region and substantially surrounding the air stream delivery lines; igniting the fuel gas to create a flame; and delivering a stream of oxygen through the jets tangentially to the flame envelope to substantially shape and stabilize a swirling flow field for the flame, the oxygen concentration in the flame envelope gradually increasing towards an outer periphery of the flame envelope. A boiler system for using the method can be a new system or a retrofit to an existing system. The method and system provide advantages in reduced environmental impact and increased efficiency while addressing the safety factors involved in introducing oxygen to boiler systems.
Abstract:
A system for providing wind-assisted air supply to coal-fired power plants through the use of a wind funnel communicating with an air handler system of a coal-fired boiler is disclosed. The shape, size and orientation of the wind funnel may be controlled in order to optimize the collection of wind and generation of increased air pressure for delivery to the coal-fired boiler system. Increased operating efficiency of coal-fired power plants may be achieved with the wind funnel system.
Abstract:
A cooling system comprises serpentine cooling fluid passages cast into a work piece with carefully controlled turning radii and profiles. Individual interdigitated baffles are contoured in the plane of coolant flow to have walls that thicken and then round off at their distal ends. The outside radii at these turns is similarly rounded and controlled such that the coolant flow will not be swirled into eddies.
Abstract:
An air port damper system (10) for a recovery boiler employs plural louvers (22) for altering the exit angle of air through an air port. Dampers (60, 62, 64, 66) 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 shutdown of the boiler.
Abstract:
A blower for use to provide combustion air to a fire (e.g., to assist in the lighting of a fire). The blower may include a cylindrical housing having an inlet opening and an outlet opening with a bore extending between the inlet and the outlet. A fan and power source may be provided to induce air flow from the inlet opening and through the bore such that air is expelled from the outlet opening. The outlet air exiting the outlet opening may travel in a direction substantially parallel with a central axis of the cylindrical housing. The blower may be supported by an infinitely adjustable flexible member that may be manipulated to position the blower with respect to the fire to provide outlet air to the fire. The flexible member may be engaged with a clip to attach the blower to a structure adjacent to the fire.
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.

Abstract:
The subject of the invention is a device from the field of regulation and automatic regulation of flue gas flow to ensure the optimal conditions of combustion and from the field of regulation and/or control of combustion. A device to regulate and optimize combustion in solid-fuel heating devices characterized by including a control unit with a preprogrammed algorithm that, on the basis of the received commands triggered by the power being switched on with a switch, remote control, smartphone or smart tablet, received data from the flue gases sensor, the sensor for residual oxygen in the flue gases and a negative pressure sensor, opens or closes a system of three regulation flaps; including a negative pressure sensor with the purpose of regulating the air flaps and performing the safety functions; the control unit, when it detects a negative pressure, enables the control of the air flaps during the various phases of combustion to achieve the desired air flow and performs the safety function of preventing the escape of flue gases into the room.
