The Design Requirements of EWB Smokeless Stove - Coursework Example

Author’s name Instructors’ name Course Date The Design Requirements of EWB Smokeless Stove According to Pope et al, (2013), the design of smokeless stove involves keeping the fire in the middle of a conical structure where it is fed through a covered opening in the front section. The front opening should be approximately 3.5" high and also 6" across. Further, the pan or pot is then placed on the top section of the opening which measures 6.43" in diameter. The exit of smoke up several feet an out the house is done through the pipe which is 4"-diameter. In addition, the top parts of the conical structure piece of material, as well as the bottom parts, are held apart using four or five rectangular slabs around 1"-thick. These slabs are also spaced equally around the same diameter. They should also have removable pieces which measures 3.5" x 9". This piece should be designed in a way that it wills the opening in front. A steel material is used to make to the 4"-pipe. This also applies to the upper funnel as wells as the conical base. However, there should be innovative techniques which should be applied in the designing of the top, the 9"-conical piece, the bottom as well as the 3"-conical pieces. The hot air and smoke which leads to conventional currents as well as the small gradient of pressure which is created by transiting wind currents at the top of 4"-pipe helps in putting away the steady wind by using the gap placed at the bottom and also out the top of the 4"-pipe. Further, besides removing the smoke, the oxygen which is added makes the fuel to burn in a more clean and efficient manner. Pope et al, (2013) suggest that this means the use of this scarce fuel is extended more than the current designs of the smokeless stove ,which are said to be fuel efficient. In addition, it is not possible for the smoke to diffuse back down since it must first stay in the inner side of the conical piece and also it cannot travel drown far in order to escape. Finally, the oxygen which is inside this chamber also helps in the diffusion of oxygen. Literature Review (EVALUATION SUPPORTING DOCUMENTS) According to Heymann et al, (2014), it is evident that most Nepal people use open fires in their houses for various purposes. These include heating, lighting or simply cooking purposes. It therefore means that one does not need to ask why the rise of respiratory related complications are such high in this country. Sattaur (1999), states that this is mostly evident in both children and women. Pine wood usage in the regions of Humla which high ion altitude. The pine wood produces a lot of black smoke and has a great amount of resin in it. According to statistics, an average household in this region uses 20-40 kilograms of firewood in lighting, cooking and heating. . In actual sense, specifically Cooking uses large amounts of this fire wood ion preparing traditional meals. Sattaur (1999) observes that smokeless metal stove was developed to protect people's health. This is the process of combustion is efficient enough. The exit of all smoke is through the chimney. Furthermore, according to Sattaur (1999), the indoor air is usually clean and the consumption of firewood is reduced by 50% . Heymann et al, (2014), contend that it makes people able to cook the traditional meals since the stove consists of three burners. The top heating plate has a split which ensures that women can bake their locally made bread without opening the main fire door. At the same time, a water tank of stainless steel with a volume of 9 liters is fixed to this stove. Sattaur (1999) agrees to the act that it provides hot clean water for washing as well as for drinking. Smokeless Stoves is a solution to heath problems According to Sattaur (1999), it was in 1998 that the project director and the co-founder of RIDS-Nepal developed smokeless metal stove for the first time. After 9 months, which involved thorough improvement and testing, the stove finally functioned satisfactorily. It was thus ready to be produced. This stove was manufactured specifically for Humla region to improve their living condition, taking ion mind their cultural and eating. Sattaur (1999) observes that the SMS consumption is estimated to be about 50% less than firewood. It cooks faster and its efficiency is always high with higher efficiency. According to statistics, since the start of 1999 about 4500 homes have benefited from these initiatives. They are offered this stove with a financial subsidy of 50%. This is on condition that they are wiling to be engaged in the holistic initiative involving the entire community which is run in partnership with the villagers. According to Osteria (2004), in the mountain Humla regions, with high altitude, community members make use of these fires in cooking and heating in the middles of their homes. This is usually the case in winter which runs for five months starting from November to march. This has been associated with widespread cases of diseases. According to the Workshop on Rural Energy Planning in the Developing Countries of Asia, & Bajracharya (2002), it is evident from surveys that the population suffers so much from these terrible conditions of indoor air pollution. According to studies, the daily average the levels of specific matters exposure is higher compared to the internationally allowed standards. Therefore, some of the health conditions include infections in the eyes, lungs, chest among other complications. Further, some other devastating effects as a result of these fires include children burns as they craw! According Osteria (2004), the continued fire usage is one of the main causes of deforestation in Himalayan region. This has been said to reach an alarming stage. Osteria (2004) contends that local people of Nepal are taught how to use, maintain as well as clean properly the SMS. This is important in order the residents can expect a long life expectancy of SMS, which is more than 30'000 hours or roughly for 15 years! The financial subsidy of 50% provided to locals who partner in the project mostly comes from donors and other project partners. The stove makes use of the double bottom which is insulated using the locally available mud. This ensures the stove have good mass and thermal stability. Further, Osteria (2004) observes that the combustion chamber which acts as fire box has been designed in a way that ensures that the flames can be adjusted easily through the dynamic air flow valve. These flames hit the three burners in the middle. The usage of the fire wood is drastically reduced since the heating of cooking pot is efficient enough. Further, the chimney consists of the exhaust air draught which is regulated using adjustable damper valve. This valve is placed in the three slots which are found in the pipe. Therefore, as the fire burns efficiently the precious fire wood is saved. The 10 year experience of smokeless metal stove consumption has indicted that the health of the residents situation in such regions have improved drastically. The majority of the people can now breathe without any difficulty and homes are now cleaner without experiencing the black smoke in the air. Smoke generated through indoor fires from cooking or heating as well as heating, is the ‘killer in the kitchen. Sattaur (1999), states that the exposure to smoke from biomass resources impairs the body’s self-defense especially the lungs at various multiple levels. It also contributes to the increase of risk of both tuberculosis disease and its infections. The concern on environmental and health matters have spurred more research into how clean cooking can be developed. Benefits of Smokeless Metal Stove There are a lot of advantages associated with SMS, as indicated above. This includes the fact that the stove is durable compared to other forms of heating. If there is good maintenance and training, the consumption can be over fifteen years. However, this depends on how one is using his stove especially cleaning it regularly. According to Osteria (2004), the cost is also not high. This is because the stove only uses locally available materials. Besides this, one can use the stove through different ways simultaneously, due to the presence of three burners. However, this depends on the design which has been used. As mentioned, pollution is drastically reduced and therefore people are not at risk of having respiratory related complications and thus the environment is safe with the consumption of this stove. Conclusions There is need to do more in the improvement of designing of this SMS. The future can even be more enjoyable for those people using SMS if portability aspect can be integrated in all of the existing current designing processes. This is because there is a growing concern that many of the rural people need even more portable solutions. Designers of SMS can see how they can come up with a lighter version say, 10lbs. Many developers are coming up with collapsible steel versions of stoves that are insulated using locally produced and fired clay. These kinds of solutions would significantly reduce the weight and also increase the portability. It will definitely solve most of the problems encountered by the poor people in most areas of not only Nepal but in the whole world. The above benefits are a clear indication that the use of SMS goes a long way in helping many poor communities worldwide. References Heymann, J., & Barrera, M. (2014).
