Annular Vortex Combustion (AVC) Development for Space/Water Heating Applications
Abstract
This is the final report for Annular Vortex Combustor (AVC) development for commercial applications. The work culminated in the successful demonstration of a 2-MB/H proof-of-concept (POC) model firing coal-water slurry fuel (CWF) and dry pulverized coals. This development was concerned with a new concept in combustion for which there was a general lack of relevant information. The work began with a cold flow modeling study and with the design and test of two subscale models (0. 15 and 0. 3 MB/H) and one full-scale model (3 MB/H) to obtain the needed information. With the experience gained, the 2-MB/H POC model was then designed and demonstrated. Although these models were designed somewhat different from one another, they all performed well and demonstrated the superiority of the concept. In summary, test results have shown that AVC can be fired on several coal fuels (CWF, dry ultrafine coal, utility grind pulverized coal) at high combustion efficiency (>99 percent), high firing intensity (up to 0.44 MB/H-ft3), and at temperatures sufficiently low for dry ash removal and in-situ pollution abatement. The combustion process is completed totally inside the combustor. Conventional combustion enhancement techniques such as preheating (air and/or fuel), precombustion, and post-combustion are not needed.
