【 摘 要 】

Gas Technological Development Center (CDT de GAS) has developed a new gas-heated self-contained steam jacketed kettle as a solution for temperature-controlled cooking of pulp fruit in the Colombian traditional candy-making industry. This initiative seeks to contribute to the promotion of natural gas as a cleaner and more efficient alternative to traditional fuels such as wood and coal in the Andean countries. Prototype follows the operational and safety rules provided by international and local standards: ASTM-F1602, ASME (section VIII, division 1), and NTC-4082. This paper presents the methodology, experimental setup and results obtained during the performance tests for heating efficiency evaluation of the kettle, according to the ASTM-F1785 standard, and the estimation of measurement uncertainty according to GUM method. The heating efficiency rate for this new prototype is higher to the convectional and commercial models of gas heated self-contained steam jacketed kettle. The results showed a heating efficiency of 63.83% ± 1.66% (k=2), whereas the emission of CO and NOXin stack gases was under the regulate limits for natural gas equipment.
