“…Dependences of the ignition delay time of the studied hydrocarbon droplets on the heating medium temperature in range from 450 to 700 °C are presented in Figure 4. For all samples the ignition delay time τi was found to exponentially decrease with the increasing of heating medium temperature which was in good correspondence with earlier published articles [29][30][31]. The average ignition delay time of the studied samples was reduced by 19.2 times with increase in the temperature from 450 °C to 700 °C.…”

The technical characteristics of liquid hydrocarbons obtained by steam gasification of the recycled automobile tires were studied as well as the features of their combustion process. Steam gasification of grinded tires was carried out in a tubular reactor using superheated steam with 500°C temperature and 5 kg/h mass flow rate. The obtained characteristics were compared with a traditional liquid fuel oil. The technical characteristics were determined via the standard analytical methods. An ignition and a combustion of liquid hydrocarbon samples were carried out in the combustion chamber at different temperatures of heating medium Tg = 450–700°C. Gas-phase combustion products were analyzed using a flow-through gas analyzer. It was found that liquid hydrocarbons were characterized by a low pour point (-43°C – (-52) °C) and comparable to calorific value of traditional fuel oil (40.56–43.3 MJ/kg). In addition, the studied samples of liquid hydrocarbons were characterized by a lower ignition delay time (by 56 %, on average) and flame burning time (by 30 %, on average). Combustion process of the studied samples (including traditional fuel oil) was accompanied by the formation of micro-explosions.

The experimental study was carried out to investigate the gasification of urotropine (hexamethylenetetramine) in a low-temperature solid fuel gas generator under varying inlet gas flows. Nitrogen was applied as the filter gas. The filter gas flow was varied from 0.6 to 1.4 L/s with a step of 0.2 L/s. The inlet gas's initial temperature was equal to 910 K. It was shown that with an increase in the nitrogen flow, the fuel gasification time decreased. Increasing the flux of inlet nitrogen from 0.6 to 1.4 L/s results in an increase in the average urotropine gasification mass rate from 0.63 to 1.61 g/s. When the initial nitrogen flow is raised, the rate of fuel gasification increases almost linearly. Studies have demonstrated that the proportion of mass flows between urotropine gasification products and nitrogen remains constant regardless of the incoming gas flow. The mass flow ratio remains steady at approximately 0.9 g/g when the incoming gas flow is altered. It has been shown that the gaseous products of urotropine gasification consist of nitrogen with a small amount of hydrogen and hydrocarbons. The content of simple gaseous products does not exceed 4% vol.

“…It has been experimentally established that the efficiency of processing a number of hardly combustible materials with a low ash content, for example, viscous hydrocarbon liquids, can be significantly increased by mixing the initial fuel with a solid noncombustible material [14,15]. The energy parameters of gasification obtained in this case have higher values than when burning fuel with the addition of wood or peat [16,17].…”

The energy efficiency of the gasification of various solid fuels in the filtration combustion mode is evaluated. The modes of gasification of carbon and organic fuels with the moisture content of up to 70% and ash content of up to 90% are considered. The efficiency of air gasification of low-moisture carbon fuels does not exceed 70%; and of organic fuels, 85%. The efficiency of the air gasification of high-moisture fuels can reach 85-90%. The addition of steam to the gaseous oxidizer increases the efficiency of the process. The efficiency of steam-air the gasification of low-moisture low-ash carbon fuels reaches 85%. In the case of organic fuels, the maximum efficiency of steam-air gasification is observed for fuels with an ash content of 20 to 40%. For highly reactive fuels, the maximum efficiency is observed for ashless fuels. If the reactivity of the fuel is low, the highest gasification efficiency will be for high ash fuels.
