“…Table 3 suggests that the temperature of the first peak is between 277 and 319°C, whereas the temperature of the second peak is in the range of 428-471°C. The first major peaks developed are due to the combustion of volatile matter [14,28,29], which originates from the thermal decomposition of holocellulose and partial decomposition of lignin [28]. The second major peaks triggered are owing to the combustion of remaining lignin and char or fixed carbon [13,17,28,30].…”

“…This demand has been met by fossil fuels particularly from coal until now. Coal gangue is composed of various minerals and accretes with coal stratum [3][4][5][6].Its dominant minerals are quartz and silicate layered clay minerals. Currently, it is one of the largest emissions of industrial solid waste.…”

Abstract. In this paper, the co-combustion behaviour of lignite coal with coal gangue and coal are investigated by a thermogravimetric analysis (TGA) in the temperature range from ambient temperature to 1000 ℃. The thermal characteristics and kinetics of lignite coal, coal gangue and their blends are evaluated under combustion conditions using a non-isothermal thermogravimetric method (TGA). Lignite coal is blended with coal gangue in the range of 25-75 wt. % to evaluate their cocombustion behaviour. Such attempts of Combustion characteristics index under different proportions of analysis may help to identify appropriate blend proportion for a given coal gangue and to derive some specific advantages with respect to particular combustion practice.

The combustion of two kinds of biomass and sewage sludge was studied. The biomass fuels were wood biomass (pellets) and agriculture biomass (oat). The sewage sludge came from waste water treatment plant. The biomass and sludge percentage in blends with coal were 10 %. The studied materials were characterised in terms of their proximate and ultimate analysis and calorific value. The composition of the ash of the studied fuels was also carried out. The behaviour of studied fuels was investigated by thermogravimetric analysis (TG, DTG and DTA). The samples were heated from an ambient temperature up to 1,000°C at a constant three rates: 10, 40 and 100°C min -1 in 40 mL min -1 air flow. TG, DTG and DTA analysis showed differences between coal, biomass fuels and sewage sludge. 10 % addition of studied fuels to the mixture with coal changed its combustion profile in the case of sewage sludge addition. The combustion characteristics of fuel mixtures showed, respectively, qualitative summarise behaviour based on single fuels. Evolved gaseous products from the decomposition of studied samples were identified. This study showed that thermogravimetric analysis connected with mass spectrometry is useful techniques to investigate the combustion and co-combustion of biomass fuels, and sewage sludge, together with coal. Nonisothermal kinetic analysis was used to evaluate the Arrhenius activation energy and the pre-exponential factor. The kinetic parameters were calculated using KissingerAkahira-Sunose model.
