Book Description
A summary of the progress achieved under the above referenced contract during the third quarter is reported here. After instituting a number of modifications, a suitable preheat flame which could provide the desired vaporization surface temperature to within an acceptable heat-up time (approx. 30 secs) was finally attained. Successful switchover to a stable vaporized and pre-mixed blue oil flame was also obtained. Preliminary data with this blue flame are presented along with vaporization surface temperature history. Adaptation of this configuration to the boiler was also initiated during this quarter so that thermal efficiency and other measurements could be conducted to assess the relative merits of oil vaporization over the spray combustion flame. Some peripheral problems identified during this experimental phase still need to be resolved during the adaptation. The details of the above results and some preliminary data obtained in the thermal efficiency set-up with the preheat flame alone are presented in the body of this report.
