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:
A pneumatic fuel distributor for solid fuel boilers is described incorporating in various embodiments one or more of the following features: a converging nozzle section, a converging adjustable orifice section and an integral trajectory plate. The nozzle, orifice and trajectory plate are preferably all interconnected and rotate together about a common axis. The orifice damper is, in one embodiment, a rotating convergent section and independently adjustable. The unit preferably incorporates a viewing glass and access port and the rotating components are preferably removable for maintenance. The unit is preferably reversible for left or right hand installation and the trajectory plate is easily replaceable.
Abstract:
A method and system for generating a signature for determining whether a web page is in a first state or a second state, comprising the steps of selecting a plurality of web pages for processing, requesting the web pages in the first state, dividing the first state pages into a first set of text blocks, requesting the web pages in the second state, dividing the second state pages into a second set of text blocks, eliminating from the first and second sets the text blocks that are common between the first and second set, generating a signature comprising the text blocks of the first set as a component indicative of the first state and the text blocks of the second set as a component indicative of the second state.
Abstract:
Methods for treatment of pulmonary hypertension include administration of a first amount of treprostinil and administration of a second amount of a Rho kinase inhibitor such that the first amount and the second amount form together an amount effective for pulmonary hypertension treatment. Kits for treatment pulmonary hypertension are also disclosed.
Abstract:
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.
Abstract:
Ion blocking layers are interposed between the outer electrodes and the active layers in a five-layer electrochromic device. The ion-blocking layers are optically transparent and electronically conductive to provide for electron transport while blocking the transport of ions between the active layers and the outer electrode layers.
