The study focuses on the design of the MK3 kiln as an eco-friendly solution to mitigate the pollution of (PM2.5 and PM10) generated by artisanal brick kilns. The MK3 kiln consists of three chambers constructed with construction and demolition waste (CDW), interconnected by lower ducts that aid in the continuous flow of heat and filter pollutants. Each kiln has a 5 cm opening in the dome to accommodate a copper industrial torch with a power of 1080 BTU/h, equivalent to 0.32 kW. Additionally, a 220V axial fan is installed in the chimney to supply the necessary air to the kilns through upper ducts, allowing complete combustion during the brick baking process. As a result, PM2.5 was measured at a quantity of 23 μg/m 3 , and PM10 emissions at 90 μg/m 3 , both of which do not exceed Environmental Quality Standards (ECA). Regarding the brick baking process, heat is recovered from the "combust...

The study of the MK4 kiln reveals notable results, highlighting its efficiency in firing bricks through convection heat exchange, avoiding heat losses in kilns (1) and (2), achieving a final firing temperature of 995.6 °C in 160 min, this system not only accelerates the cooking process, but also contributes significantly to the overall efficiency, benefiting comprehensive operational efficiency not only improves the quality of the final product, but also promotes sustainability and profitability in the manufacture of bricks, indicating a faster and more uniform firing. Likewise, it demonstrates optimal results in its cogeneration system, having an energy efficiency of 60% in 160 min of cooking, generating a heat recovery temperature of 596.5 °C in each oven (3) and (4). In addition, the pollutants PM2.5 and PM10, through the gravitational force, the particles settle during the cooking ...

The study focuses on the energy efficiency of the MK3 kiln through the cogeneration system, as a solution to reduce the use of natural resources that are currently used in the artisanal kiln to generate combustion in the production of artisanal bricks. The results in the brick firing process were obtained in the first 30 minutes, with a temperature of 410.8 °C, marking the beginning of the firing process, at 150 minutes, it reached 771.2 °C, generating efficient thermal insulation. At 240 minutes, the kiln reached 975.4 °C, evidencing the completion of the firing of the brick. The MK3 kiln stands out for its exceptional energy by using an innovative cogeneration system that is equivalent to a temperature of 486.5 °C, obtaining an energy efficiency of 50% in the continuous brick firing system, generating a positive impact on sustainable development., thus reducing fuel consumption in ...
