ResumenEl objetivo del trabajo que se presenta es mejorar el rendimiento térmico de cocinas industriales que utilizan gas licuado de petróleo (GLP) a fin de promover el buen uso del recurso en la ciudad de Lima. Los experimentos fueron realizados en un banco de ensayos, donde se registraron variables físicas que utiliza el modelo del prototipo. Luego se determinó la potencia y rendimiento de varias cocinas industriales del mercado peruano para comparar con el diseño de la cocina prototipo considerando dos normas internacionales. El quemador dio un amplio rango de potencia según la presión de trabajo utilizado y un alto rendimiento de 59% comparado con las cocinas que se comercializan a nivel nacional que en promedio están en 45%. La ventaja de esta cocina prototipo es que usa presiones de operación entre 28 a 60 mbar comparada con las cocinas del mercado peruano que usan presiones entre 3 a 6 bar, disminuyendo de esta manera los riesgos asociados a incendio y explosión.Palabras clave: cocinas industriales, eficiencia térmica, gas licuado de petróleo. AbstractThe objective of the work presented in this paper is to improve the thermal performance of industrial stoves that use liquefied petroleum gas (LPG) in order to promote good use of the resource in the city of Lima. The tests were carried out in a test bench, where physical variables were registered to be used in the prototype model. Then, the power and performance of several industrial stoves in the Peruvian market were determined to compare with the design of the prototype device considering two international standards. The burner gave a wide range of power according to the working pressure used and a high efficiency of 59% compared to the stoves that are nationwide sold, which are on average 45%. The advantage of this prototype device is that it uses operating pressures between 28 to 60 mbar compared to kitchens in the Peruvian market that use pressures between 3 to 6 bar, thus reducing the risks associated with fire and explosion.

This research aimed to improve the thermal performance of industrial kitchens using liquefied petroleum gas in Metropolitan Lima in order to promote good use of energy and reduce the impacts of climate change. The methodology was to use an appropriate test bench under the international technical norms of combustible gases, the appropriate instrumentation was used to record the variables such as temperature, pressure, mass flow, relative humidity, the burner and the prototype kitchen were designed using models mathematicians using computational tools such as Mathcad and matlab, then the burner was built and installed in the prototype kitchen and test bench to perform the experimental part. Then, the powers and performances of several industrial kitchens in the Peruvian market were determined to compare with the design of the prototype kitchen following the experimental methodology of 02 international standards, one Latin American and one Asian. The burner designed and manufactured gave a wide range of power according to the working pressure used and a high efficiency of 59% compared to the kitchens that are sold nationwide, which on average are 45%. The advantage of this prototype kitchen is that it uses operating pressures between 28 to 60 mbar compared to kitchens in the Peruvian market that use pressures between 3 to 6 bar, thus reducing the risks associated with fire and explosion.
