“…Application of the quartz pipe and the sight-glass in the metal shield (9) allowed to observe directly, to film and to photograph the combustion process of the suspension. The compressed air or the nitrogen was transported to the quartz tube (2) through the electro-valves (10), control valves (11,12), and rotameters (13,14). Time transmeters (15) with a switch (16) regulating operation of electrovalves allowed to change automatically the flux time of the gas.…”

“…Improvement of the process required to urgently undertake the research explaining this type of combustion technology. In the specialist literature we can find some texts concerning coal-water suspensions as well as in-depth papers dealing with the combustion processes of various fuels, including fuel wastes [2][3][4][5][6][7][8][9][10][11]. The current research is directed into two main problems: 1) to present a study on the combustion technology of low-concentration coal-water suspension which will decrease NO x emission.…”

Analysis of cyclic combustion of the coal-water suspension Combustion technology of the coal-water suspension creates a number of new possibilities to organize the combustion process fulfilling contemporary requirements, e.g. in the environment protection. Therefore the in-depth analysis is necessary to examine the technical application of coal as a fuel in the form of suspension. The research undertakes the complex investigations of the continuous coal-water suspension as well as cyclic combustion. The cyclic nature of fuel combustion results from the movement of the loose material in the flow contour of the circulating fluidized bed (CFB): combustion chamber, cyclone and downcomer. The experimental results proved that the cyclic change of oxygen concentration around fuel, led to the vital change of both combustion mechanisms and combustion kinetics. The mathematical model of the process of fuel combustion has been presented. Its original concept is based on the allowance for cyclic changes of concentrations of oxygen around the fuel. It enables the prognosis for change of the surface and the centre temperatures as well as mass loss of the fuel during combustion in air, in the fluidized bed and during the cyclic combustion.

Straipsnyje analizuojama kietojo biokuro, naudojamo Lietuvoje, būklė, plėtros galimy bės ir poveikis aplinkai bei indėlis į klimato kaitą. Nustatyta, kad kietojo biokuro poten cia las 2011 m. buvo 1 442 ktne ir jo panaudojimas šilumos sektoriuje siekė 50,8 %. Iki 2020 m. potencialas turėtų padidėti 14,6 % ir pasiekti 1 648 ktne, o kietojo biokuro potencialo panaudojimas šilumos sektoriuje turėtų išaugti iki 67 %. Įgyvendinus Lie tuvos strateginiuose dokumentuose numatytą kietojo biokuro naudojimo šilumos gamybai plėtrą, būtų sudaryta galimybė iki 2020 m. šalyje šiltnamio efektą sukeliančių dujų emisiją sumažinti 6 %. Pagrindinių orą teršiančių medžiagų emisija pakistų skirtingai. SO 2 , NO x ir KD emisijos sumažėtų atitinkamai 13,1, 3,2 ir 28,4 %, tačiau LOJ ir CO emisijos padidėtų atitinkamai 1,3 ir 8,2 %.
