Available in PDF, EPUB and Kindle. Book excerpt: Based on fundamental research concerning swirling flows, including the vortex breakdown phenomenon, as well as on stability considerations of premixed flames, a second generation of low-emission burners has been developed. The lean premixing technique provides NOx emissions below 25 ppmv for natural gas. For liquid fuels the oxides of nitrogen are limited to 42 ppmv (oil No. 2). The novel burner technology will be applied to the well-known ABB silo combustor. As a first step the Conical Premix Burner will be used to retrofit the ABB type 11N. For the ABB gas turbine type 8 the design of a novel fully annular combustor is in progress. Most of the conceptual work concerning burner aerodynamics and burner-burner interaction has been carried out on scaled-down burner and combustor models. For a second step a sector of the combustor in 1:1 scale has been tested at atmospheric pressure. Additional high-pressure tests provide information about the combustor performance at engine conditions. The present paper summarizes the results of the first two steps beginning with the early ideas in the conceptual phase up to the 1:1 tests, which prove the low-NOx capability for both gaseous and liquid fuels under atmospheric pressure conditions.

Available in PDF, EPUB and Kindle. Book excerpt: In spite of the increasing presence of renewable energy sources, fossil fuels will remain the primary supply of the world's energy needs for the upcoming future. Modern gas-turbine based systems represent one of the most efficient large-scale power generation technology currently available. Alongside this, gas-turbine power plants operate with very low emissions, have flexible operational characteristics and are able to utilize a broad range of fuels. It is expected that gas-turbine based plants will play an important role as an effective means of converting combustion energy in the future as well, because of the vast potential energy savings. The numerical approach to the design of complex systems such as gas-turbines has gained a continuous growth of interest in the last few decades. This because simulations are foreseen to provide a tremendous increase in the combustor efficiency, fuel-flexibility and quality over the next future. In this dissertation, an advanced turbulent combustion technique is implemented and progressively developed for the simulation of all the features that are typically observed in stationary gas-turbine combustion, including hydrogen as a fuel. The developed turbulent combustion model retains most of the accuracy of a detailed simulation while drastically reducing its computational time. As a result of this work, the advancement of power generation plants can be accelerated, paving the way for future developments of alternative fuel usage in a cleaner and more efficient combustion.

Book excerpt: Controls for emissions of oxides of nitrogen were first required for gas turbines by the Los Angeles County Air Pollution Control District (LAAPCD) and the San Diego Air Pollution Control District (SDAPCD) in the early 1970's. To achieve the necessary control, water was injected into the combustor flame zone to reduce flame temperature. The consequent reduction in NOx amounted to about forty percent when half as much water as fuel was injected into the reaction zone. The emissions level achieved was approximately 75 ppmvd (parts per million by volume dry) on oil fuel as required by SDAPCD Rule 68, and with the airflow of these MS5000 machines at about 950,000 lbm/hr, this corresponded to 140 lbm/hr of NO2 when expressed at 15% O2 as required by LAAPCD Rule 67. Hilt and Waslo, (Ref. 1) and Hilt, et al (Ref. 2, 3) provide summary discussions of this work.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The successful development of the coal-based integrated gasification combined cycle (IGCC) with carbon capture and storage (CCS) requires gas turbines capable of achieving dry low nitrogen oxide (NOx) combustion of hydrogen-rich syngas fuels for low emissions and high plant efficiency. This chapter describes the development of a "multi-cluster combustor" as a state-of-the-art dry low NOx combustor for hydrogen-rich syngas fuels. The combustor consists of multiple clusters of pairs of one fuel nozzle and one air hole that are installed coaxially. The essence of the design concept is the integration of two key technologies: rapid mixing of fuel and air for low NOx and flame lifting for flashback-resistant combustion. The combustor has been developed in three steps: burner development, combustor development, and feasibility demonstration for practical plants. The combustor was tested with a practical syngas fuel in a multi-can combustor configuration in an IGCC pilot plant in the final step. The combustor achieved the dry low NOx combustion of the syngas fuel in the pilot plant and the test results demonstrated the feasibility for achieving dry low NOx combustion of the syngas fuel in practical plants.

Book excerpt: Master's Thesis from the year 2014 in the subject Engineering - Power Engineering, grade: 1.0, Brandenburg Technical University Cottbus, language: English, comment: Simulation eines Prufstands einer Gasturbinenbrennkammer mit einem Reaktor Netzwerk und detaillierter Chemie, abstract: Use of gas turbines as one of the most effective power generation technologies has ecological concerns caused by polluting combustion products. To reduce emissions different fuel compositions are being constantly investigated and gas turbines are developed by means of experiments or less expensive numerical simulations. Combustion processes can be modeled in computational fluid dynamics (CFD) with a good accuracy but it is time consuming and rather complicated in case of detailed chemistry. To overcome this issue a processing of CFD solution can be applied for a further building of equivalent chemical reactor networks (CRN) that allow to reduce calculation times and take minor species into account. The aim of this work is to choose a proper technique of CRN set-up and apply it for engineering tasks with the software tool 'LOGEsoft ReactorNetwork'. The first part of the thesis is devoted to investigation of existing CRN approaches, CFD processing instruments and testing and improvement of the 'LOGEsoft ReactorNetwork'. That software is successfully examined on the Sandia Flame D and a parameter study of the reactor network is carried out. The second part involves mechanism validation for methane/hydrogen mixtures and development of an equivalent reactor network for the Siemens atmospheric combustion test rig that serves as an experimental facility for enhancement of the 3rd generation dry low emission burner. The obtained CRN is validated against experimental data of NOx measurements and it showed reasonable results with deviations. A parameter study and mechanism sensitivity of the model is also conducted and some ways for the future improvement are suggested.

This book was released on 1990 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents the results obtained from a 1/8 th scale rich-quench-lean (RQL) combustor designed for ultra-low NOx operation running at Allison 501-K engine simulated full and part load conditions. The goal of the test program was to demonstrate the capability of the combustor to limit oxides of nitrogen (NOx) emissions to less than 10 ppmv and provide simultaneous control of carbon monoxide (CO) emissions to below 50 ppmv, both corrected to 15% oxygen. The tests were conducted on a refractory-lined bench scale combustor developed originally to support the advanced coal fired gas turbine program which is sponsored in part by the Department of Energy (DoE) Morgantown Energy Technology Center (METC). Measurements were made of NOx and CO emissions from natural gas (NG) and distillate fuel number 2 (DF#2) with water injection at simulated full and part power operation over a range of rich, quench and lean zone temperatures. The results show that the NOx goals of the test program were met and that CO emissions could be further controlled to less than 10 PPMVD on both fuels. The thermodynamic constraints of the system, the airflow splits and water injection rate requirements are discussed together with the combustor general design parameters. Estimates are also made for the required steam injection rate to produce the same NOx and CO emission levels.
