Title: Engineering development of coal-fired high performance power systems phase 2 and 3

Abstract

The goals of the program are to develop a coal-fired high performance power generation system (HIPPS) that is capable of: thermal efficiency (HHV) {ge} 47%; NOx, SOx, and particulates {le}10% NSPS (New Source Performance Standard); coal providing {ge} 65% of heat input; all solid wastes benign; and cost of electricity {le} 90% of present plants. Phase 1, which began in 1992, focused on the analysis of various configurations of indirectly fired cycles and on technical assessments of alternative plant subsystems and components, including performance requirements, developmental status, design options, complexity and reliability, and capital and operating costs. Phase 1 also included preliminary R and D and the preparation of designs for HIPPS commercial plants approximately 300 MWe in size. This phase, Phase 2, involves the development and testing of plant subsystems, refinement and updating of the HIPPS commercial plant design, and the site selection and engineering design of a HIPPS prototype plant. Work reported herein is from: Task 2.2 HITAF Air Heaters; and Task 2.4 Duct Heater and Gas Turbine Integration.

  • The goals of the program are to develop a coal-fired high performance power generation system (HIPPS) by the year 2000 that is capable of: >47% thermal efficiency (HHV); NO{sub x}, SO{sub x} and particulates {ge} 10% NSPS; coal {ge} 65% of heat input; all solid wastes benign; and cost of electricity 90% of present plant. The HIPPS generating plant integrates a combustion gas turbine/HRSG combined cycle arrangement with an advanced coal-fired boiler. The unique feature of the HIPPS plant is the partial heating of gas turbine (GT) compressor outlet air using energy released by firing coal in the high temperaturemore » advanced furnace (HITAF). The compressed air is additionally heated prior to entering the GT expander section by burning natural gas. Energy available, in the gas turbine exhaust and in the HITAF flue gas are used in a steam cycle to maximize energy production. The HIPPS plant arrangement is thus a combination of existing technologies (gas turbine, heat recovery boilers, conventional steam cycle) and new technologies (the HITAF design especially the heater located in the radiant section). Work reported herein is from Task 1.3, HIPPS Commercial Design and Task 2.2, HITAF Air Heaters.« less

  • Most of the available computational models for Selective Non- Catalytic Reduction (SNCR) systems are capable of identifying injection parameters such as spray droplet size, injection angles and velocity. These results allow identification of the appropriate injection locations based on the temperature window and mixing for effective dispersion of the reagent. However, in order to quantify No{sub x} reduction and estimate the potential for ammonia slip, a kinetic model must be coupled with the mixing predictions. Typically, reaction mechanisms for SNCR consist of over 100 elementary steps occurring between approximately 30 different species. Trying to model a mechanism of this sizemore » is not practical. This ABB project incorporated development of SNCR systems including NO{sub x} reduction and ammonia slip. The model was validated using data collected from a large-scale experimental test facility. The model developed under this project can be utilized for the SNCR system design applicable to HIPPS. The HITAF design in the HIPPS project includes low NO{sub x} firing system in the coal combustor and both selective non-catalytic reduction (SNCR) downstream of the radiant heating section and selective catalytic reduction in a lower temperature zone. The performance of the SNCR will dictate the capacity and capital cost requirements of the SCR.« less

The criteria associated with a commercial HIPPS plantmore » design as well as possible environmental control options are presented. The design of the HITAF air heaters, both radiative and convective, is the most critical task in the program. In this report, a summary of the effort associated with the radiative air heater designs that have been considered is provided. The primary testing of the air heater design will be carried out in the UND/EERC pilot-scale furnace; progress to date on the design and construction of the furnace is a major part of this report. The results of laboratory and bench scale activities associated with defining slag properties are presented. Correct material selection is critical for the success of the concept; the materials, both ceramic and metallic, being considered for radiant air heater are presented.
