The objective of this study is to investigate how the location of fire source impacts the species generation. From the standpoint of fire safety, toxicity need to be estimated from the product gases evolved under different conditions of pool fire inside the compartment. However, industries like chemical, nuclear and thermal power plants also possess fuel positions significantly above the floor level inside an enclosure. Also, marine diesel fuel storage position in the ship cabin is just above the base, which implies an elevated pool fire conditions. In the present investigation, the severity of product gases with different pan diameters (ranges from 0.2 to 0.8 m) along with diesel fuel pan elevations in terms of toxicity were analysed. In order to study the behaviour of various fuel position, a large pool diameter 0.8 m was burned in centre, corner and rear wall centre along with six different fire source elevation. Results were analysed in terms of heat release rate (HRR), ratio of CO₂/CO, upper hot gas temperature, residence time of upper hot gas, CO yield, CO₂ yield and fractional effective dose (FED). The maximum HRR was obtained in the range of 10 kW to 1100 kW. For large pool diameter, results of CO₂/CO ratio shows exponential decay trend along with fuel pan elevation, the maximum concentration of CO increased with increase in ceiling temperature showed parabolic trend. Moreover, lower CO₂/CO ratio addresses incomplete combustion and thereby leads to higher toxicity inside the compartment.

这项研究的目的是调查火源的位置如何影响物种的产生。从防火安全的角度出发，需要根据舱室内不同火池条件下放出的产物气体来估算毒性。但是，化学，核能和火力发电厂等行业的燃料位置也明显高于机柜内部的地面高度。另外，船舱中船用柴油的存储位置正好位于底座的上方，这意味着水池着火情况加剧。在本研究中，分析了具有不同锅径（范围从0.2到0.8 m）的产品气体的严重性以及柴油锅的毒性。为了研究各种燃料位置的行为，在中心燃烧了一个直径为0.8 m的大水池，墙角和后墙中心以及六个不同的火源高度。根据放热率（HRR），CO比率对结果进行了分析₂ / CO，上部热气温度，上部热气停留时间，CO产率，CO ₂ 产率和有效分数分数（FED）。获得的最大HRR在10 kW至1100 kW的范围内。对于较大的水池直径，CO ₂ / CO比的结果显示出随着燃料锅高度的增加而呈指数衰减的趋势，随着顶棚温度的升高，CO的最大浓度呈抛物线趋势。此外，较低的CO ₂ / CO比可解决不完全燃烧的问题，从而导致车厢内的毒性更高。
