“…To slow the gas speeds, a cooking chamber is placed above the stove that redirects the combusted gases radially outward toward a chimney to direct the expelled gasses and the energy they hold in the form of heat away from the cooking chamber. The distributed form is an alternative to specific multipot stove designs where only two temperature options are available [14].…”

“…One of the biggest issues with the cookstove, though, is the inability to safely and effectively add fuel to the system once the stove begins firing and having multiple regions to cook at different temperatures [14]. The right image of Figure 1 shows a TLUD example where no fuel port is available to continue feeding the combustion process nor an option to move to lower temperature locations.…”

Biomass cookstoves are used as a common source of heating and cooking in developing countries with most improved cookstove design focusing on developing efficiency in thermal conversion of fuels and safer operation than open flame fires. A top-lit-up-draft (TLUD) cookstove utilizes a gasification process similar to pyrolysis where the solid biomass fuels are heated within a oxygen-limited environment and the syngas are burned which reduces carbon content and particulate matter being introduced into the air. The new continuous-operation design is described to have features for: (1) safe addition of solid fuels during combustion of syngas, (2) removal of biochar at the primary air inlet to manage gasification location, and (3) temperature control of the cooksurface through adjustable exhaust paths. The designed cookstove is found to have a diameter to height ratio 0.42-0.47 in order to offer the cleanest burning of the biofuel. The cooking surface is experimentally studied and the thermal gradient is found for compressed wood pellets. Tracking of the coal-bed is studied as a function of time in order to better understand when additional fuel should be added to ensure constant cooking temperature and operation. Numerous exhaust paths explore the cookstove user’s ability to control the temperature contour of the cooksurface.

“…Several researchers have experimented with improving the efficiency of cookstoves and reported that it is possible to get the masses to accept it (Food and Agriculture Organization, 2010; Jeuland & Pattanayak, 2012; Pattanayak et al, 2019; Thakur et al, 2019). In India, improved cook stoves (ICS), which improve the efficiency of cooking, are an often-used idea to reduce firewood consumption, lower the smoke released from the kitchen and thereby help women improve their health and conserve native trees of the area (Pande et al, 2018). It has been a common perception that households below the poverty line would prefer using ICS if they are made available at low costs, to reduce indoor air pollution, but the progress in adopting ICS on large scale has been exceptionally slow (Bailis et al, 2009; Jeuland & Pattanayak, 2012).…”

“…In India, after independence, the effort to introduce efficient cook stoves became a part of development projects initiated by various government and non-governmental organisations. Today, in the rural parts of India, the inability to create effective designs has made it difficult for people to cook certain culturally important types of foods and has resulted in a reluctance to use ICS (Adler, 2010; Bhojvaid et al, 2014; Khandelwal et al, 2016; Pande et al, 2018).…”

According to the 2001 Census of India, around 82% of the rural population of India depends entirely on biomass and uses primitive cookstoves for cooking. The smoke released due to incomplete combustion causes several chronic respiratory disorders among women responsible for cooking. Despite these adverse effects, people continue to use traditional cookstoves due to their simplicity. Firewood consumption is also responsible for the degradation of forests and the emission of CO2, which is a major greenhouse gas. A project was implemented by Wildlife Research and Conservation Society in 12 villages in Melghat Tiger Reserve to introduce improved cook stoves in 1,098 households for reducing firewood consumption and smoke emission. This study estimated that the improved cookstoves (ICS) had reduced the average per capita firewood consumption by 0.61 kg/day (25%) and resulted in the conservation of 1,171 tons of firewood annually. A decrease of 1,953 tons of CO2 emissions due to the installation of ICS has been estimated. Installation of ICS reduced the time taken to cook a meal by an average of 40 minutes and reduced smoke production, thereby contributing to the health of the users.

“…They noticed desired performance for stove manufacturing with modified height. Pande et al (2019) [13] studied the flaws in the traditional existing stoves in rural locations of Maharastra. Their modified stove model increased the thermal efficiency which was compared with traditionally used cook stoves through experimental analysis.…”

In India, Silk industry plays an important part in textile industry. Muga silk, the golden yellow silk is quite unique to Assam, North-east India where its production is regarded as an important tool for economic development. But, outdated manufacturing technology is followed during the silk production in Assam. The existing cooking process of silk cocoons consists of boiling of silk cocoons in a stainless steel vessel along with water and soda in an open fireplace which is highly energy inefficient. Therefore, two modified systems have been designed; one having cylindrical boiling chamber (vessel) and the other having spherical boiling chamber (vessel). Both the chambers are having a cocoon heating chamber associated with them for cooking and drying of silk cocoons simultaneously. These designs are further classified into two types of designs based on channel and nozzle type combustion chambers. Therefore, the main objective of this paper is to improve the existing designs to maximize the utilization of heat carried by the combustion gases. These modified systems are analysed by using Computational Fluid Dynamics (CFD) selecting standard k–є model. From the analysis, it is seen that these new systems having nozzle type combustion chambers are more efficient than the systems having cylindrical combustion chambers and if these systems are used in silk production, it will be very beneficial for the silk industry as well as for our society.
