Design and experimental analysis of an improved burner with natural gas

This research aimed to improve the thermal performance of industrial cookstoves using natural gas in Metropolitan Lima 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 standards of fuel gases; the appropriate instrumentation was used to record the variables such as temperature, pressure, mass flow, and relative air humidity. The burner was installed in the prototype cookstove and test bench to perform the experimental part. After that, the powers and performances of several industrial cookstoves in the Peruvian market were determined for comparison with the design of the prototype cookstove following the experimental methodology of 02 international standards, one Latin American and one Asian. The burner designed and manufactured in previous research gave a wide range of natural gas power according to the working pressure used and high efficiency of approximately 57% compared to the cookstoves that are sold nationwide, which on average is 53%. The advantage of this prototype cookstove is that it uses operating pressures between 23 and 34 mbar compared to stoves in the Peruvian market that do not have a standard of the maximum gas pressure.
