Title: Method and apparatus for optimizing the combustion air system in a recovery boiler
Inventor: ULOTH VICTOR
IPC: F23L3/00
Filed: 2000-07-11
Abstract: A method and an apparatus for optimizing the combustion air system in a power boiler or chemical recovery boiler by improving fluid flow and gas mixing are disclosed, whereby one can increase boiler capacity and combustion uniformity and reduce particulate and gaseous emissions. The method involves interlacing of the secondary and, where applicable, the tertiary air supply through opposing air ports on all four walls of the boiler, and is implemented by alternately opening wide or partially closing a port damper on one side, while partially closing or opening wide a port damper on the opposite side, such that a 70-100% open damper on one side opposes a partially closed (10-40% open) damper on the other and vice versa in an alternating fashion, along opposing walls. In a preferred embodiment, the optimization is further enhanced by balancing primary air flow, achieved by adjusting port dampers and windbox pressures so that the primary air flow is evenly distributed between opposite walls, between all four walls of the boiler and between individual airports on each wall. Windbox pressure and other key measurements of boiler operation ensure proper balancing and an adequate interlacing of air flows at the primary, secondary and tertiary elevations, respectively.

Patent CA-2322224-A1 (CA)
Inventor: GUNNARSSON FREDRIK
IPC: H04B7/005
Filed: 1999-02-23
Abstract: A method and system for quality-based transmission power control in a cellular communications system are disclosed, whereby a network operator can specify the transmission quality requirements using a measurement that better reflects the actual quality perceived by the users.  All transmitter power levels in the network can be controlled by identical power regulators, each of which can adapt to individual traffic situations in order to achieve the specified quality. For example, in a GSM   frequency--hopping network, the FER together with the parameters estimated from the current traffic situation, are mapped onto a target C/I, which in turn, the power control algorithm strives to achieve. Consequently, the power regulators can adapt to the traffic situation experienced by each receiver.

IPC: H04B10/556
Filed: 2000-12-05
Abstract: In the system for communicating a management message between nodes in a wavelength division multiplexing network 1, each of the nodes has a switching unit 101 for switching a transmission path of an optical channel signal carried by the network. The optical channel signal has a frame in compliance with the SDH/SONET standard that stipulates the Data Communication Channel Bytes D4-D12 in the Line Overhead Byte to be allocated for a management message.    Each of the nodes includes a termination and generation means for terminating the bytes D4-D12 and extracts a management message from the bytes when each of the nodes receives the optical channel signal. The node judges an optical channel to carry said management message and incorporates new bytes of the same byte structure as bytes D4-D12 into the optical channel signal in place for the terminated bytes D4-D12. The new bytes are entered with a management message to be carried by the same channel as that of the optical channel signal of interest. The switching unit 101 switches the transmission path to route the optical channel signal together with the new bytes to the destination node.
