3 Thermal Technologies, Environmentally Friendly Clean Energy CFB Combustion Circulating Fluidized Bed (CFB) meets high acceptance and is base technology, applied in power plants and other industries for steam generation by combustion of low/high quality coal, biomass, sludges, RDF and other residual fuels. Enhanced downstream flue gas treatment is available for waste combustion and is designed in accordance with the latest environmental standards. In addition to CFB, ENVIROTHERM s portfolio includes the stationary (FB) fluidized bed technology. Both CFB and FB offer proven and reliable technologies with excellent emission values. Numerous CFB/FB plants have been built. ENVIROTHERM s activities are highlighted by Stadtwerke Flensburg, Germany, combined heat and power plant: Engineering for a re-fuelling project to co-fire up to 25 % (energy) of biomass and RdF (high CV and high Cl content) in three 150 t/h hard coal fired boilers Cottbus, Germany, combined heat and power plant: Redesign / supply of 12 cyclones and reengineering of in-bed bundles in a pressurized lignite fired fluidized bed boiler (82 MW el ) Vojany, Slovak Republic Turkey, three CFB boilers up to 460 t/h steam, in collaboration with SES / Slovak Republic. 3

4 Clean Energy Thermal Technologies, Environmentally Friendly CFB Gasification Circulating Fluidized Bed (CFB) gasification is applied in the power, steel and other gas consuming industries for the gasification of various feedstocks ranging from low/high quality coal and waste materials to CO 2 neutral biomass. The unit capacity range corresponds to 5-50 MW el. CFB is operated at temperatures below ash softening point (i. e C), with an even temperature profile in the reactor and excellent heat and mass transport. Thus the CFB gasification technology is well suited for temperature sensitive (alkaline containing) fuels like various types of coal and biomass (woodchips, straw etc.). Numerous CFB plants have been built. ENVIROTHERM s CFB gasification activities are represented by the following references: CFB gasification of RdF in the cement industry Ruedersdorf, Germany CFB gasification of demolition wood Geertruidenberg, The Netherlands CFB gasification of high ash Indian coal and lignite Barbil, India, two units permit engineering for a 5 MW el straw gasification plant, Germany Barbil, India The commercially operated gasification units generate 50,000 Nm³/h syngas each. 4

5 Thermal Technologies, Environmentally Friendly Clean Energy BGL Gasification Schwarze Pumpe, Germany The BGL offers compelling competitive advantages like high cold gas efficiency (82 % - 93 %) high specific fuel throughput low oxygen consumption low steam consumption low aqueous liquor production high fuel flexibility: nearly all coal qualities and other types of fuels (e.g. waste) can be processed excellent load following capabilities The BGL (British Gas Lurgi) fixed bed slagging gasifier operates at pressures up to 40 bar. Fields of application are power, chemicals and fertilizer industries as well as producers of liquid fuels or synthetic natural gas. slag as by-product is non-leachable and can be re-utilized enables CO 2 capture and storage ( CCS ) modular design with a nominal capacity of approx. 1,000 tons of coal per day, equivalent to approx. 150 MW el (depending on feedstock) proven and robust design 14 BGL gasifiers are currently under engineering or construction, thereof 12 in China and 2 in India. Application is for ammonia, urea and fuel gas generation. Commissioning is planned from 2012 onwards. 5

6 Clean Energy Thermal Technologies, Environmentally Friendly Hazardous Waste Incineration Izmit, Turkey 6

7 ENVIROTHERM supplies plants for the incineration of various types of solid and liquid hazardous waste in a rotary kiln. Long residence time in the rotary kiln in connection with a downstream high temperature post combustion chamber is meant to ensure an excellent burn-out and complete destruction of hazardous substances. Heat from the hot flue gases is recovered by a waste heat boiler and converted into electric power in a steam turbine. The cooled flue gas is cleaned in a modern flue gas treatment plant to highest emission standards. The flue gas treatment plant is tailor made and may be effluent free depending on local conditions and requirements. ENVIROTHERM can draw on a number of 25 hazardous waste incineration plants built worldwide. One of them is located in Izmit / Turkey, has a waste incineration capacity of 35,000 t/a and provides for the generation of steam at a rate of 27 t/h to be converted into 5.2 MW el. 7

8 Clean Air Air Pollution Control Technologies Flue Gas Cleaning ENVIROTHERM s flue gas cleaning technologies are best suited for power plants, sludge, municipal solid waste or hazardous waste incineration plants. All plants are tailor made acc. to capacity and expected contaminants. They provide for the elimination of toxic substances to meet most stringent environmental standards. The cleaning units consist of proven and reliable components. Effluent free units are available for coping with challenging local conditions and requirements. ENVIROTHERM s flue gas cleaning plants are part of numerous sewage sludge and hazardous waste incineration plants. 8

9 Air Pollution Control Technologies Clean Air SCR Catalyst For more than 50 years ENVIROTHERM s catalysts have been developed and continuously improved for the application in catalytic reduction processes, e. g. for the reduction of nitrogen oxides in the flue gas of power plants (SCR technology, ZERONOX ). In addition to the reduction of nitrogen oxides the ZERONOX D catalysts stand for reducing dioxins. ENVIROTHERM catalysts production, Chengdu, Sichuan, China Depending on local conditions Envirotherm s monolithic TiO 2 based honeycomb catalysts are installed either on the high dust or on the low dust side of the flue gas path. Catalytically active components can be customised for specific applications in accordance with process related requirements. They have a square cross-section of 150 x 150 mm and can be supplied up to lengths of 1,300 mm. Compared to non-catalytic processes the consumption of ammonia containing reducing agents is significantly less. The production of the catalysts has been moved into a Joint Venture in China in Over 40,000 m³ of the ZERONOX and ZERONOX D catalysts have been supplied. This is equivalent to a nitrogen oxides reduction capacity of approximately 40,000 MW of electrical power station capacity. 9
