The civilization development requires improvement of technologies and satisfaction people’s needs on the one side, but other it is directly connected with increasing production waste. In this paper, authors dealt second these aspects, reviewing recycling plastic waste, which can be processed without changing its chemical structure (mechanical recycling), (chemical recycling, thermal recycling). Mechanical involves shredding waste in order to obtain recyclate or regranulate that meets...
The paper presents a tally of the results thermal analysis TG/DTG/DSC selected fuels (hard coal, agro biomass and forest biomass), waste (coal sludge, fly ash), quartz sand with organic material, recyclate polyamide PA6. materials differ in composition calorific values. aim study was complex comparative tested inthe scope potential use coal fuels, to create polymer composites, as well co-utilization waste, energy recovery from plastic waste. permits illustrate change sample mass obtain...
The main element of the work was economic analysis resulting from use a photovoltaic installation cooperating with heat pump in one single-family houses. It should be emphasized that cooperation photovoltaics and pumps, aimed at ensuring thermal comfort building generating electricity, e.g. for operation pump, it is most economically advantageous technologies. In this work, authors focused only on assessment payback time sample installation, operating Poland. Based investment costs its...
Nowadays oxy-fuel combustion of coal and biomass is the most promising option for reduction CO2 emissions from power plants. In this paper, NOx (NO, NO2, N2O their precursors, such as NH3 HCN), SO2 CO during conventional three kinds (agro, woody energy crop) a reference are presented discussed. Combustion tests were conducted at 850 °C in laboratory-scale circulating fluidized bed (CFB) reactor air O2/CO2 atmospheres. A FTIR spectrometer was used to measure instantaneous concentrations all...
Abstract The objective of this study was to investigate combustion characteristics biomass (willow, Salix viminalis ) burnt in air and O 2 /CO mixtures a circulating fluidized bed (CFB). Air oxy-combustion wooden CFB were supplemented by the thermogravimetric differential thermal analyses (TGA/DTA). results conducted TGA tests show that composition oxidizing atmosphere strongly influences process fuels. Replacing N environment CO caused slight delay (higher ignition temperature lower maximum...
The topic of waste combustion/co-combustion is critical, given the increasingly restrictive legal regulations regarding its environmental aspects. In this paper, authors present test results selected fuels different compositions: hard coal, coal sludge, coke waste, sewage paper biomass and polymer waste. conducted a proximate ultimate analysis materials mercury content in them their ashes. An interesting element was chemical XRF fuels. preliminary combustion research using new bench. provide...
The topic of waste incineration/co-incineration is critical, given the increasingly stringent regulations on environmental aspects. widespread use polymeric materials generates significant waste, posing an ecological problem. Current mandate a reduction in landfilling plastic which should be replaced by recycling, with possi-bility exploiting energy potential due to its high calorific value. electricity generation Poland mainly based coal, so using polymers as alternative fuels important...
In the paper problem of heavily-watered fuel combustion has been undertaken as requirements qualitative coals combusted in power stations have growing. Coal mines that want to fulfill expectations engineers forced extend and modernize coal enrichment plants. This causes growing quantity waste materials arise during process wet containing smaller under-grains. this situation idea transported materials, for example a hydraulic way nearby appears attractive because possible elimination...
Analysis of cyclic combustion the coal-water suspension Combustion technology creates a number new possibilities to organize process fulfilling contemporary requirements, e.g. in environment protection. Therefore in-depth analysis is necessary examine technical application coal as fuel form suspension. The research undertakes complex investigations continuous well combustion. nature results from movement loose material flow contour circulating fluidized bed (CFB): chamber, cyclone and...
