Análisis teórico y experimental de la potencia y eficiencia térmica de cocinas industriales que usan gas licuado de petróleo

Abstract

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.
