Book Description
The use of stationary gas turbines for power generation has been growing rapidly with continuing trends predicted well into the future. Factors that are contributing to this growth include advances in turbine technology, operating and siting flexibility and low capital cost. Restructuring of the electric utility industry will provide new opportunities for on-site generation. In a competitive market, it maybe more cost effective to install small distributed generation units (like gas turbines) within the grid rather than constructing large power plants in remote locations with extensive transmission and distribution systems. For the customer, on-site generation will provide added reliability and leverage over the cost of purchased power One of the key issues that is addressed in virtually every gas turbine application is emissions, particularly NO(subscript x) emissions. Decades of research and development have significantly reduced the NO(subscript x) levels emitted from gas turbines from uncontrolled levels. Emission control technologies are continuing to evolve with older technologies being gradually phased-out while new technologies are being developed and commercialized. The objective of this study is to determine and compare the cost of NO(subscript x) control technologies for three size ranges of stationary gas turbines: 5 MW, 25 MW and 150 MW. The purpose of the comparison is to evaluate the cost effectiveness and impact of each control technology as a function of turbine size. The NO(subscript x) control technologies evaluated in this study include: Lean premix combustion, also known as dry low NO(subscript x) (DLN) combustion; Catalytic combustion; Water/steam injection; Selective catalytic reduction (SCR)--low temperature, conventional, high temperature; and SCONO(subscript x){trademark}.

Book Description
Available Information on control of NOx emissions from stationary combustion sources has been compiled to assist new source permitting activities by regulatory agencies. The sources covered are combustion turbines, Internal combustion engines, non-utility boilers and heaters, and waste Incinerators. The report discusses the background of NO, formation in the combustion process, major NO sources, and processes for NOx control. The current status of NO control technology Is discussed and applications to meet permitting requirements Is detailed. Permitted NOx emission levels are summarized by combustion source, fuel type and control technology. Documentation includes references and contacts for further Information.

Book Description
Carbon Capture Technologies for Gas-Turbine-Based Power Plants explores current progress in one of the most capable technologies for carbon capture in gas-turbine-based power plants. It identifies the primary benefits and shortcomings of oxy-fuel combustion CO2 capture technology compared to other capture technologies such as pre-combustion and post-combustion capture. This book examines over 20 different oxy-combustion turbine (oxyturbine) power cycles by providing their main operational parameters, thermodynamics and process modelling, energy and exergy analysis and performance evaluation. The conventional natural gas combined cycle (NGCC) power plant with post-combustion capture used as the base-case scenario. The design procedure and operational characteristics of a radial NOx-less oxy-fuel gas turbine combustor are presented with CFD simulation and performance analysis of the heat exchanger network and turbomachinery. Overview of oxygen production and air separation units (ASU) and CO2 compression and purification units (CPU) are also presented and discussed. The most advanced stages of development for the leading oxyturbine power cycles are assessed using techno-economic analysis, sensitivity, risk assessments and levelized cost of energy (LCOE) and analysing technology readiness level (TRL) and development stages. The book concludes with a road map for the development of future gas turbine-based power plants with full carbon capture capabilities using the experiences of the recently demonstrated cycles. Analyzes more than 20 models of oxyturbine power cycles, identifying the main parameters regarding their operation, process and performance simulations and energy and exergy analysis Provides techno-economic analysis, TRL, sensitivity and risk analysis, LCOE and stages of development for oxy-combustion turbine power plants Presents the design procedure and CFD simulation of a radial NOx-less oxy-fuel gas turbine combustor exploring its influence on heat exchanger network and turbomachinery Supports practitioners, policymakers and energy industry managers seeking pathways to convert coal-fired power plants to gas-fired plants with zero CO2 emission

Book Description
The EPA has proposed a 9.2 g/kWh NOx limit for maritime diesel engines. Gas turbines, which are always cleaner burning, have escaped maritime NOx mandates at this time. However, in Europe, increasingly stricter exhaust emission limits for shipboard turbines near high-pollution ports undergo periodic review. Anticipating these proposed mandates, the Navy has been directed by OPNAVINST 5090 1A to comply therewith. EPA studies show that two-cycle marine diesel configurations combining exhaust-gas recirculation, retardation of the timing of injection, intercooling, and an oxidation catalyst for combustion of particulates lower NOx-emission levels to 8.5 g/kWh. Water injection appears ineffective below water-fuel ratios of 0.4, and is not cost effective for achieving the required NOx emission objective, at least in two-cycle engines. The proposed diesel configuration eliminates any negative ship impact on the engine-room spaces from water-management systems and water logistics. Contrastingly, water injection into the combustor of gas turbines is a state-of-the-art development, which may be a low-risk, low-cost option for reduction of gas-turbine emissions. It is anticipated that the required pure water would be obtained from water purification plants and stored supplies.
