Development and testing of a high efficiency advanced coal combustor: Industrial boiler retrofit

PDF Version Also Available for Download.

Description

Under U.S. Department of Energy, Pittsburgh Energy Technology Center (PETC) support, the development of a High Efficiency Advanced Coal Combustor (HEACC) has been in progress since 1987 at the ABB Power Plant Laboratories. As summarized in previous publications on the subject, the initial work produced an advanced coal firing system that was capable of firing both water-based and dry pulverized coal in an industrial boiler environment. With continued DOE-PETC support, carried out in cooperation with the Energy and Fuels Research Center of The Pennsylvania State University (Penn State), the HEACC burner concept has been used as a major component in ... continued below

Description

Under U.S. Department of Energy, Pittsburgh Energy Technology Center (PETC) support, the development of a High Efficiency Advanced Coal Combustor (HEACC) has been in progress since 1987 at the ABB Power Plant Laboratories. As summarized in previous publications on the subject, the initial work produced an advanced coal firing system that was capable of firing both water-based and dry pulverized coal in an industrial boiler environment. With continued DOE-PETC support, carried out in cooperation with the Energy and Fuels Research Center of The Pennsylvania State University (Penn State), the HEACC burner concept has been used as a major component in a system design intended for industrial-scale, coal fired retrofit applications. The overall objective of the current work is to demonstrate the technical and economic feasibility of retro a gas/oil-designed industrial boiler to burn micronized coal. In this respect, the major technical goals for the combustion system design have included: a compact, easy to retrofit burner design; low NOx generation, while maintaining high combustion efficiency; commercially acceptable combustion air pressure drop and burner turndown ratio; and integration of coal preparation system controls into boiler control system The design of the HEACC burner is based on the well established principle of internal air staging for NOx control.
