Research ArticleOpen accessEvery word in the titleThe Utilization of Peat, Lignite and Industrial Wastes in the Production of Mineral-Organic FertilizersKrystyna Hoffmann, Józef HoffmannThe results of chemical analyses of the composition of peat, lignite, turkey droppings and the potato industry effluent are presented. The results indicate that the substances can be used in mineral-organic fertilizer recipes. Although lignite and peat do not contain assimilable nutrients, from the ecology and pedology point of view they are valuable components of mineral-organic fertilizers. In order to … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,481 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleInvestigation of Lignite and Firewood Co-combustion in a Furnace for Tobacco Curing ApplicationNakorn Tippayawong, Chutchawan Tantakitti, Satis ThavornunCo-combustion of lignite and firewood was investigated for an application in tobacco curing industry in Northern Thailand. Extensive experiments have been carried out in a newly developed furnace suitable for small curing unit, in place of locally made furnace. The aim of this investigation is to evaluate the performance of the combustion chamber in the required thermal output range for … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 31 Mar 2006 · 6,901 accessesView PDF Cite

Research NotesOpen accessIn the keywordsThermal Drying Methods on Coal Liquefaction ConversionMehran HeydariThe sample coal used in this work was lignite containing 25% of moisture and 19% of ash from Canada. Drying of lignite coal had considerable influence on the coal liquefaction conversion. Vacuum dried and nitrogen dried samples provided higher conversion than air dried samples. The air drying showed nearly lower conversion, which probably as a result of oxidation. Air Drying … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 12 Mar 2019 · 7,868 accessesView PDF Cite

Research ArticleOpen accessIn the abstractElectron Spin Resonance Study of Tertiary Sediments in Mae Moh Basin, Lampang ProvinceTidarut Vichaidid, Supanee Limsuwan, Pichet LimsuwanElectron Spin Resonance (ESR) studies have been carried out on Tertiary sediment collected from Mae Moh basin, well known for its lignite mining in Lampang province of the northern Thailand, a stratigraphic bedding plane in the sediment that formed in geological time of about 13 million years ago. Each individual sedimentary bed has its own unique assemblage and occurs in … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 14 Jul 2012 · 7,172 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvaluation of Hydroponic Production of Vegetables and Ornamental Pot-Plants in a Heated Greenhouse in Western Macedonia, GreeceIoannis I. Papadopoulos, Fotis Chatzitheodoridis, Christos Papadopoulos et al.In this research an evaluation-in terms of investments-of hydroponics greenhouses is carried out, as well as the possibility of the development of greenhouse crops cultivations, such as vegetables and flowers, in them is explored in Western Macedonia. The survey was realized between the years 2002-2006, in a model greenhouse, which was installed by the Public Power Corporation S.A., in soils … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 8,183 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAssessment of Pulverised Fly Ash (PFA) as an Ameliorant of Lead Contaminated SoilsEdmond Gatima, Mwinyikione Mwinyihija, Ken KillhamFly Ash (FA) is obtained by electrostatic or mechanical precipitation of dust-like particles from the flue gases of furnace fired with coal or lignite at 1100 to 1400°C. About 95-99% of Fly Ash consists of oxides of Si, Al, Fe and Ca, about 0.5 to 3.5% consists of Na, P, K and S and the remainder is composed of trace … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,014 accessesView PDF Cite
