“…Because the increase in the secondary air was accompanied by a decrease in the primary air and therefore, increasing the bed temperature. This finding was is in agreement with the results reported in [38] who studied the co-combustion of municipal solid waste and Thai lignite in a laboratory scale bubbling fluidized bed combustor. In the secondary air injection area the temperature dropped slightly in the upper region owing the secondary air consumed energy to reach the combustion temperature and this result also supported by Madhiyanon et al [27].…”

Abstract.A laboratory scale bubbling fluidized bed combustor was designed and fabricated to study the combustion of dewatered poultry sludge at different operational parameters. This paper present a study on the influence of equivalent ratio, secondary to primary air ratio and the fuel feed rate on the temperature distribution along the combustor. The equivalent ratio has been changed between 0.8 to 1.4% under poultry sludge feed rate of 10 kg/h and from 0.8 to 1 under poultry sludge feed rate of 15 kg/h. The secondary to primary air ratio was varied from 0.1 to 0.5 at 0.65 m injection height and 1.25 equivalent ratio. The results showed that these factors had a significant influence on the combustion characteristics of poultry sludge. The temperature distribution along the combustor was found to be strongly dependent on the fuel feed rate and the equivalent ratio and it increased when these two factors increased. However, the secondary air ratio increased the temperature in the lower region of the combustor while no significant effect was observed at the upper region of the combustor. The results suggested that the poultry sludge can be used as a fuel with high thermal combustor efficiency.

“…However, when ϕ exceeded 1.9, η decreased with ϕ increasing. This was because that the temperature in the tube furnace would be inevitably decreased to some extent with the increase of ϕ due to more cool air to be heated up [11]. The decrease in furnace temperature thus led to the drop of η.…”

This work aims at demonstrating the feasibility of replacing Indonesian coal (INC) with hydrothermally treated municipal solid waste (MSWH) in cocombustion with high ash Indian coal (IC). The combustion efficiencies and emissions (CO, NO) of MSWH, INC and their blends with IC for a series of tests performed under a range of temperatures and air conditions were tested in a droptube reactor (DTR). The results showed the following. The combustion efficiency of IC was increased by blending both MSWH and INC and CO emission was reduced with increasing temperature. For NO emission, the blending of MSWH led to the increase of NO concentration whereas the effects of INC depended on the temperature. The combustion behaviors of IC-MSWH blend were comparable to those of the IC-INC blend indicating it is possible for MSWH to become a good substitute for INC supporting IC combustion. Moreover, the CO emission fell while the NO emission rose with increasing excess air for IC-MSWH blend at 900• C and the highest combustion efficiency was obtained at the excess air of 1.9. The existence of moisture in the cocombustion system of IC-MSWH blend could slightly improve the combustion efficiency, reduce CO, and increase NO.

“…The waste burning conventionally in the open atmosphere cause environmental pollution due to the incomplete combustion process. It will produce harmful gasses such as CO, SO2, NO, NOx, N2O, HCl, HF, dioxins and volatile organic compounds (VOCs) especially polyaromatic hydrocarbons (PAH), polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxine/-furans (PCDD/Fs) and leachable toxic heavy metals [7][8][9]. Additionally, energy in the form of heat generated from the combustion process is wasted to the environment.…”
