“…Three individual PRBs of diameter 70 mm are clustered to form a CPRB. The detailed description of the set-up can be found in [6]. The individual PRBs of the CPRB are reported to function similarly and thus the temperature plots of only one individual burner is considered to be sufficient to depict the variations of temperature with ϕ and power input.…”

“…The individual burners of the CPRB are supplied with required quantities of air and fuel mixture as per the power input and ϕ. The ϕ is calculated as per the following formula [6] φ =15.45×A/F (1) where, A and F are the actual mass flow rates of air and fuel, respectively. The fuel and air enter the mixer separately through different streams and are mixed as they flow towards the burner outlet.…”

“…In recent studies [5,6], the authors research team has demonstrated that the use of a Clustered Porous Radiant Burner (CPRB) is advantageous in increasing the thermal efficiency and reducing emissions compared to a single-PRB. These investigations were carried out for burner operation on submerged combustion mode.…”

“…A PRB is an excess enthalpy burner that predominantly works on the principle of radiation [2]. A PRB is made up of two layers of which one acts as a preheating layer and the other acts as a combustion layer [3]. It has a mixing zone and a mixing tube through which the air-fuel mixture is given as input [4].…”

“…The same dimensions are best suited for lean-burn for cylindrical PRB too. The research was also done on cluster PRB used in commercial cooking applications to test its stability in a submerged state [6]. The experiment showed that the cluster PRB could combust in a stable state for an 8-20 kW input range.…”

The present study is to conduct a Techno-economic Assessment of a 5-7 kW Porous Radiant Burner (PRB) – based LPG cook-stove operating in eateries and restaurants. Process flow study has been performed primarily to understand the technological process involved in the PRB and also to estimate the cost of manufacturing. The cost estimation has been done considering direct costs such as material costs and labor costs, and indirect costs such as factory costs, works costs and administration costs. Sensitivity analysis has been performed considering the production capacity of 50, 250 and 500 cook-stoves each day. An economic feasibility study of PRB cook-stoves has been done by estimating the Pay Back Period, Net Present Value and Internal Rate of Return. For a manufacturing capacity of 250 cook-stoves per day, PRB yields a 51.4% return on the investment with a payback period of 0.68 years. Adopting PRB-based cook-stoves in small, medium and large-scale eateries results in an annual saving of Rs. 77500, Rs. 235000 and Rs. 1170000, indicating that PRB-based cook-stoves are undoubtedly economically viable.

The present study analyses the emission mitigation ability of a Porous Media Combustion (PMC) technology based cookstove (𝐶𝑆 𝑃𝑀𝐶 ) compared to a Free Flame Combustion (FFC) technology based cookstove (𝐶𝑆 𝐹𝐹𝐶 ).Emission of pollutants i.e., PM2.5, PM10 and CO caused due to burning of fuels namely methanol, ethanol, kerosene and LPG in the kitchen environment are measured. The study incorporated exhaustive real-time indoor air quality (IAQ) measurements and presented the temporal variation of measured pollutant concentrations for 2 h (morning meal duration). In addition, 24 h average concentration of the measured pollutants is also compared with the limits prescribed in WHO guidelines for domestic settings. The results emphasised that the utilisation of 𝐶𝑆 𝑃𝑀𝐶 would help in improving the IAQ of the kitchen area by decreasing the concentrations of PM2.5, PM10 and CO.For 2 h duration measurements, the methanol cookstove based on PMC reduced the concentrations of PM2.5, PM10 and CO by 7.7%, 8.1% and 17.2% respectively, compared to FFC cookstove. Similarly, in the case of PMC based LPG cookstove ( 𝐶𝑆 𝑃𝑀𝐶 𝐿𝑃𝐺 ) and kerosene cookstove (𝐶𝑆 𝑃𝑀𝐶 𝐾𝑒𝑟𝑜𝑠𝑒𝑛𝑒 ), the respective values were 11.7%, 20.4% and 41.6% and 55.3%, 62.6% and 66.6%. Among all the tested cookstoves, 𝐶𝑆 𝑃𝑀𝐶 𝐿𝑃𝐺 achieved the lowest emission values (PM2.5: 20.6 𝜇𝑔/𝑚 3 ; PM10: 31.3 𝜇𝑔/𝑚 3 and CO: 1 ppm) which are lower than the prescribed WHO values (PM2.5: 25 𝜇𝑔/𝑚 3 ; PM10: 50 𝜇𝑔/𝑚 3 and CO: 6 ppm).
