“…[ 8 ] Arghode and Gupta indicated the difference between the premixed and the non‐premixed burners, and it was shown that the flame formed on a non‐premixed burner had a more distinctive colour. [ 9 ] Darwish et al [ 10 ] examined butanol blended diesel fuel combustion in a temperature‐controlled burner. The temperature of the incoming air was changed with proportional integral derivative (PID) control so that the equivalence ratio was between 0.86 and 0.76.…”

“…It was also concluded that OH radicals increased only in diesel fuel, but when butane was added into the fuel, the OH intermediate density decreased. [ 10 ] Ilbas and Karyeyen [ 11 ] conducted experimental studies on hydrogen‐containing fuels combustion in a premixed burner under conventional conditions. The results showed that coke oven gas showed better combustion performance than that of city gas.…”

Fuels consisting of high hydrogen concentration can be consumed under colourless distributed combustion (CDC) to suppress flashback tendency in premixed conditions. Higher NOX challenges can also be overcome through CDC. For those purposes, coke oven gas was consumed under CDC within the scope of this study. To achieve CDC, or diluents were introduced into the oxidizer so that oxygen concentration in the oxidizer would be decreased from 21% O2 to its lean blow‐off limits. Excess air ratios were determined as λ = 1.2 and λ = 1.5 along with a thermal power of 10 kW under premixed conditions. A commercial computational fluid dynamics code was used to predict temperature distribution and , CO, and emissions. 162‐step reactions created with GRI‐Mech 3.0 chemical kinetics was integrated to the eddy dissipation concept combustion model. The temperature and profiles predicted were compared with the experimental results. Consistency was achieved at ~95% for temperature profiles, and almost 100% for profiles between the measured and the predicted ones. According to the results, it is concluded that a more homogeneous temperature distribution with the ~21% decrease in the maximum temperature was observed, and there was about 96% decrease in level. It was also demonstrated that using as a diluent is more effective in terms of temperature distribution over the combustor and reduction, while dilution with is more effective in terms about 70% in decrease on CO.

“…At present, ABF is widely used in engine fuels, industrial power generation, and heating 20 , 21 . In particular, alcohol-based fuels can be mixed with diesel and biodiesel fuel into excellent industry and transportation mixed fuels, among which butanol can significantly improve the combustion state of the mixed fuel formed with diesel, and has good effects in improving temperature control ability and reducing CO and NOx emissions 22 . Kilic et al 23 showed that when low (up to 30%) butanol is formed into fuel with diesel in flame tube boilers, combustion efficiency can be improved, which has a positive prospect for reducing emissions and improving combustion efficiency.…”

So far, coal, petroleum, and natural gas are still the most widely used fuels, and the emissions of SO2, NOX and particulate matter produced from their combustion have a serious influence on the air. Therefore, it is necessary to develop a clean fuel. In this study, the bulk curing barns were equipped with different fuel equipment, Barn A used traditional coal heating equipment; Barn B used biomass briquettes fuel (BBF) integrated heating equipment; Barn C equipped with alcohol-based fuel (ABF) heating equipment. The temperature of the outer surface of the heating equipment, the exhaust gas of the chimney, and the curing heat efficiency and energy consumption were analyzed. Compared with the barn BBF and barn coal, the barn ABF can meet the flue-cured tobacco curing highest temperature requirements of 68 °C, the accuracy of the target dry bulb temperature (DBT) curve during the curing of flue-cured tobacco was 93.4%. At the same time, during ABF combustion, the emissions of CO2 and CO were 40.82% and 0.19%, respectively. However, no emissions of NOX, SO2, and H2S were detected in the chimney exhaust. Compared with the barn BBF and barn coal, the thermal efficiency of barn ABF heating equipment in the barn was increased by 44.78% and 86.28%, respectively. Additionally, the coast per kilogram of dry tobacco was reduced by 19.44% and 45.28%, respectively. Therefore, compared to barn coal and barn BBF, the barn ABF can control temperature changes more accurately, and shows an obvious advantage in environmental protection and heat utilization efficiency.
