HIGH TEMPERATURE TURBINE TECHNOLOGY PROGRAM Phase I. Program and System Definition Topical Report—Low BTU Gas Combustor Preliminary Designs For Three Concepts

摘要

Preliminary design analysis was performed for three selected Low-Btu gas combus¬tion systems which utilized distillate oil for start-up and acceleration to idle. These three systems are 1) a can-annular design, 2) a dual-fuel, can-annular design with the additional capability to operate on distillate oil at full load when the gasifier is down and 3) an annular design.nConsiderable attention was given to wall-cooling configurations that would conserve air due to the large combustion air requirements at the 2600°F and 3000°F temperature levels. The use of Lamilloy material gave the lowest wall air cooling requirements.
