PlantWeb™ digital architecture with Ovation™ control system to provide flexible and accurate control of critical combustion process
PITTSBURG (August 2, 2011) -- Foster Wheeler has chosen Emerson Process Management's PlantWeb™ digital plant architecture with the Ovation™ expert control system and AMS Suite predictive maintenance software to control a new biomass boiler at the Polaniec Power Station in Poland. When operational in 2012, this will be the world's largest 100% biomass-fired boiler.
Foster Wheeler is building the 190 MWe biomass-fired circulating fluidized-bed (CFB) boiler island for plant owner GDF Suez, one of the world's leading energy providers. Poland has been investing in biomass power generation to achieve a target of producing 15 percent of its total energy consumption from renewable sources by 2020.
"The Foster Wheeler circulating fluidized-bed technology provides solutions for effective CO2 reduction in power generation through large-scale 100% biomass utilization," said Jarosław Mlonka, President & CEO of Foster Wheeler Energia Polska. "Emerson's proven automation technology will help overcome the difficulties of burning agricultural biomass efficiently by providing reliable, accurate and efficient boiler control."
Emerson's Ovation system features embedded advanced algorithms and proven control routines that continually adjust the combustion process to account for the varying characteristics of biomass fuels.
Emerson's scope of supply is based on an Ovation system to handle 6000 I/O. This includes Ovation SIS (Safety Instrumented System) for boiler protection and burner management. Project documentation will be generated using the Ovation Documentation Builder smart tool. Emerson will also supply automation services including complete project management, engineering and installation.
Also included is Emerson's AMS Suite, which will speed configuration and commissioning of boiler instrumentation. When the plant is operational, AMS Suite will enable maintenance and operations personnel to predict equipment issues to better maintain and protect the machinery.
The boiler island and biomass handling plant will be built next to the existing units at GDF Suez's 1,800-MW coal-fired power station, which already uses an Ovation control system. Following further modernization of the station's existing turbine, its output capacity will increase from 190 to 205 MW.
Designed for high reliability and easy maintenance, the boiler will burn wood chips in combination with 20 percent of agricultural derived fuel such as straw pellets or crushed briquettes, sunflower pellets, fruit husk pellets, and crushed palm kernel shells.
The annual biomass requirement of the new unit will be approximately one million metric tons, and it is expected to generate 1.2 terawatt hours (TWh) of clean energy annually. The plant is designed to ensure that emissions will be well below those required by the EU Large Combustion Plants Directive.
"Biomass utilization will play a significant role in Europe's energy future," said Bob Sharp, European president, Emerson Process Management. "Emerson's automation technology is perfectly placed to support power generation developments by providing advanced automation and control functions to maximise both boiler and plant efficiency."
The Federal's pistol slid into its holster and his sabre flashed out. He threw its curved point up in a splendid salute. Ferry saluted with his straight blade. Then both swords rang back into their scabbards, and Jewett whirled away toward his column. For a moment we lingered, then faced to the left, trotted, galloped. Over the fence and into the road went he--went I. Down it, as we crossed, the blue column was just moving again. Then the woods on the south swallowed us up. "All right, sir." that before. Meanwhile the parallelism between Thought and Extension was not exhausted by the identification just analysed. Extension was not only a series of movements; it still remained an expression for co-existence and adjacency.412 Spinoza, therefore, felt himself obliged to supply Thought with a correspondingly continuous quality. It is here that his chief originality lies, here that he has been most closely followed by the philosophy of our own time. Mind, he declares, is an attribute everywhere accompanying matter, co-extensive and co-infinite with space. Our own animation is the sum or the resultant of an animation clinging to every particle that enters into the composition of our bodies. When our thoughts are affected by an external impulse, to suppose that this impulse proceeds from anything material is a delusion; it is produced by the mind belonging to the body which acts on our body; although in what sense this process is to be understood remains a mystery. Spinoza has clearly explained the doctrine of animal automatism, and shown it to be perfectly conceivable;569 but he has entirely omitted to explain how the parallel influence of one thought (or feeling) on another is to be understood; for although this too is spoken of as a causal relation, it seems to be quite different from the logical concatenation described as the infinite intellect of God; and to suppose that idea follows from idea like movement from movement would amount to a complete materialisation of mind; while our philosopher would certainly have repudiated Mr. Shadworth Hodgson’s theory, that states of consciousness are only connected through their extended substratum, as the segments of a mosaic picture are held together by the underlying surface of masonry. Nor can we admit that Spinoza entertained the theory, now so popular, according to which extension and consciousness are merely different aspects of a single reality. For this would imply that the substance which they manifest had an existence of its own apart from its attributes; whereas Spinoza makes it consist of the attributes, that is to say, identifies it with their totality. We are forced, then, to conclude that the proposition declaring thought and extension to be the same thing570 has no413 other meaning than that they are connected by the double analogy which we have endeavoured to explain. “Oh, he’s welcome to it,” Sandy cried. “I’ve turned over a new leaf!” “But—are they?” He pulled a wire out a trifle from the sheath. The sergeant spent more time upon the oaths with which he embellished the counter-question as to how he should know anything about it, than would have been consumed in a civil explanation. "Doctor, he can't die. He mustn't die," said Shorty in agony. "The regiment can't spare him. He's the best soldier in it, and he's my pardner." AND ENTERS UPON HIS PARENTAL RELATIONS TO LITTLE PETE SKIDMORE. "Holy smoke, look there," gasped Monty Scruggs, as a company of rebel cavalry came tearing over the hill in front, to the assistance of their comrades. "That's about it," answered Shorty disdainfully. "That's the way with all cavalry, dad-burn 'em. They're like a passel o' fice pups. They're all yelp and bark, and howl and showin' o' teeth. They're jest goin' to tear you to pieces. But when you pick up a stone or a club, or git ready to give 'em a good kick they're gone, the devil knows where. They're only an aggravation. You never kin do nothin' with 'em, and they kin do nothin' with you. I never kin understand why God Almighty wasted his time in makin' cavalry of any kind, Yank or rebel. All our own cavalry's good for is to steal whisky and chickens from honest soldiers of the infantry. The infantry's the only thing. It's like the big dog that comes up without any special remarks, and sets his teeth in the other dog. The thing only ends when one dog or the other is badly whipped and somethin's bin accomplished." "Mmm." Reuben started out of the half-waking state into which he had fallen. It was late in the afternoon, the sunlight had gone, and a wintry twilight crept up the wall. Maude the dairy-woman was looking in at the door. It was about a month subsequent to this, that one morning, as Turner was making the anvil ring with the ponderous strokes of his hammer, two retainers from the castle entered the shed, and delivered an order from De Boteler for his immediate attendance. Wat laid the hammer on the anvil, and, passing the back of his right hand across his forehead, to clear away the large drops that stood there, looked with a kind of smile at the men as he said, HoME泷泽萝拉四部和集下载
