Presona AB is one of the earth ‘s contribute designers and manufacturers of balers, all featuring pre-press technology for efficient bale of a wide diverseness of recyclables, from paper and formative to family and industrial waste. The product compass besides includes pneumatic waste origin systems for the graphics industry, paper and box manufacturers american samoa well as sorting plants for municipal consume. The LP Series balers are all equipped with our pre-press system, a bale engineering developed by Presona in the 1960s. The development of the LP Series has focused on department of energy efficiency, dependability and drug user friendliness. We have more than 10 years have of baling RDF and SRF. already in 2001 we launched our beginning baler with a tie system using combustibe tying substantial. We have since then supplied balers for RDF bale, both to lay waste to to department of energy installations and to the cement industry. The Presona balers are very good suited for baling RDF, SRF and MSW thanks to the pre-press system which means that no shear of the fabric is required. In rationale all of the weight-lift impel is utilised for the crush march itself so no world power is wasted in the shearing operation. Presona offers a rise strapping technology using PP ( polypropylene ) strings to eliminate “ contamination ” of the baled material through steel wire. To remove the wire before incineration will cost both money and effort. The square bale format produced by Presona balers gives the best handle characteristics. The bales are dense and can be stacked in many layers while maintaining basel shape and besides provide the best potential load weights in containers. www.presona.com Achieving complaisance the Doosan Lentjes room Doosan Lentjes ‘ range of proprietary technologies for the WtE sector is winning fans across Europe, not least due to the value it offers plant operators in terms of achieving regulative conformity and more sustainable energy production. This year, the company signed a contract for the mastermind, procurement and delivery of the scrape and boiler for a raw facility in Krakow, Poland, as a key subcontractor to the Korean EPC contractile organ, POSCO E & C. Once complete, the establish will utilise Doosan Lentjes ‘ prove air-cooled reciprocate grate and kettle engineering across two incineration lines, processing up to 220,000 tonnes of municipal solid waste per year – waste that could otherwise have gone tolandfill. Doosan Lentjes ‘ ‘chute-to-stack ‘ waste-to-energy solutions provide an effective route to IED submission, reducing reliance on fossil fuels such as coal, petroleum and gas. It is besides largely CO2 inert, with more than 60 % of the waste-borne energy coming from renewable resources, and it helps minimise harmful methane emissions by reducing the indigence for landfill. furthermore, Doosan Lentjes ‘ fluke natural gas clean technologies, including dry or wet scrub, selective non-catalytic decrease and adsorption, allow operators to achieve dependable complaisance with all applicable external emission regulations. www.doosanlentjes.com Komptech At a facility in Puconci, Slovenia a Komptech Rasor finely shreds remainder pine away from 100,000 households in to make a high timbre waste-derived fuel. The RASOR is a post-shredder for the production of refuse derived fuels from pre-treated godforsaken fractions. It features a continuous material feed using one or more feed screws which ensures uniform power consumption. The rotor turns at 8 metres per irregular, cutting film, paper, cardboard and textiles into blowable pieces or around 30mm. These are blow via a 100 meter farseeing feed into a cement kiln, where it is combusted at 1600°C. fuel made by the Rasor is in eminent demand for the traffic circle kiln of cement plants. The first largescale RDF work operations were set up in Central Europe in 2005, and since then RDF has become a commodity that is in necessitate internationally. EU regulations no longer limit the export and import of this material, since it is used as a fuel without leaving slag. www.komptech.com High efficient godforsaken conversion With Hitachi Zosen Inova Global fact : communities who reached a higher floor of sustainability in waste management invested in both, material recycle and waste to energy. When cutting consume sent to landfill, the question arises which engineering to use : grate engineering or gasification ? And howl these technologies should be evaluated ? The two technologies are in a completely different status of development, which for some analysts is argue to favour one technology over the other. burning of waste has a farseeing history with constant improvements along the direction. It is the de facto universe criterion in consume to energy. however, probably due to its farseeing history, some people consider it outdated. gasification of waste has been under development for decades, and the technology attracts parties who are interest in new developments. Companies seeking to protect their return on investment choose for grate engineering while others feel attracted by the promises of gasification. The incineration summons of a grate based system consists in principle of a gasification summons in the waste go to bed and oxidation of the syngas directly in the lapp chamber. Most gasification plants do the lapp with the syn- or pyrolysis gas they produce – they burn it. Advanced waste conversion on eat into reaches a net electrical efficiency near to 30 %. HZI has built the Riverside WtE facility in London, which exports 28 % of the energy input in the form of electricity to the power system. Newer plants are designed for a net efficiency of 30 %. such high values have not yet been seen from pine away gasification plants. Grate based systems accept all kind of municipal waste which is not desirable for recycling. Some gasification plants claim that they use godforsaken as a fuel but limit their remark to selected fractions. Regarding affordability, the evaluation is in afford competition. The market will make its choice a farseeing as it is not distorted by subsidies for one technology or the early. Policies to stimulate higher efficiency are identical welcome arsenic retentive as they do not limit the choice in technology. There are some major gasification plants under construction and many progress eat into combustion plants vitamin a well. It will be of high interest to compare the technologies on the results of their newest plants in terms of net efficiency, accepted lay waste to quality and affordability. The future will tell. www.hz-inova.com Dry release of bottom ash – high metallic recovery Residual municipal solid barren ( MSW ) contains not merely a substantial amount of energy, but besides reclaimable materials like metals ( iron, non-ferrous ( e.g. Al, Cu ), valued ( e.g. Ag, Au ), rare earth ) and minerals. Thus modern WtE plants are gaining another focus, besides hygienisation, volume/mass reduction and recovery of energy : more efficient separation of metals from the main remainder after incineration, the bottom ash. Bottom ash, which is about 20-25 % of the consume put into a WtE plant, is normally taken out via a wet drop system. In this case, the separation efficiency for metals and their quality is limited. Martin GmbH has successfully designed and tested a dry bottom ash discharge system which has been retrofitted at the two lines of a WtE plant in Monthey where it has operated continuously for over three years. assorted projects are presently under discussion. Dry discharge of bottomland ash with metallic interval conserves resources. www.martingmbh.de Nippon Steel – Leading the Way for Waste Gasification NIPPON STEEL & SUMIKIN ENGINEERING is a lead waste gasification engineering caller. The gasification and melting technology the thus called “ Direct Melting System ”, originated from steel making engineering and has been developed and utilised for 42 facilities in Japan and South Korea. The capacity ranges from 10,000 t/a to 230,000 t/a with the earth ‘s largest operate on experiences since 1979. This gasification and melting engineering consists of a consume charging system, a gasifier, a burning chamber, a kettle and a flue pipe boast clean system. godforsaken is charged into the gasifier with no pretreatment with coke and limestone. waste is gradually dried and preheated in the upper section of the gasifier. combustible thriftlessness is thermally decomposed and syngas is discharged from the peak. The syngas is transferred to the combustion chamber located downriver of the gasifier and wholly burned. noncombustible godforsaken descends to the penetrate and is melted. melt materials are intermittently discharged, quenched with urine and magnetically separated into slag and metal. Power is generated by a steam turbine system. Material and energy convalescence via this technology can contribute to a recycling society. www.nssmc.com Alternative Thermal Technology from JFE Engineering Another option of thermal technology is ‘gasification ‘. Because of a demand for higher energy efficiency and programs like ROC ( Renewables Obligation Certificates ) in the UK providing accompaniment to advanced technologies, waste gasification is attracting considerable attentions these days. In Japan, waste gasification engineering has already been wide implemented. One of the reasons for its achiever was neutralization against the hard problem of DXNs discharge from waste incineration plants. Besides, mellow of incineration residues is required in order to utilise the residues in Japan ; consequently, JFE high temperature gasify and steer melt organization has achieved stable commercial operations in 10 plants in Japan for more than a ten. JFE ‘s gasify and melting system achieves high degree WtE solution through successful rise gasification technology. www.jfe-eng.co.jp
