Catalytic Combustor

An electric utility grid connected test facility has been established at Silicon Valley Power (SVP) in Santa Clara, California to validate the reliability, availability, maintainability, and durability (RAMD) of a commercial-ready catalytic combustor system (XONON). Installed in the Silicon Valley Test Facility (SVTF) is a 1.5MW Kawasaki MIA-13A gas turbine fitted with a catalytic combustor. The gas turbine package is controlled by a Woodward MicroNet control system. The combustor utilizes a two stage lean premix preburner system to obtain the required catalyst inlet temperatures and low NOx over the operating load range. The fuel-air mixer incorporates counter rotating swirlers to mix the catalyst fuel and air to achieve the desired uniformity. The patented catalyst design is composed of specially coated metal foils. Overall engine performance was measured and the emissions were continuously monitored. As of Dec. 1999, emissions of NOx<2.5 ppmv and CO and UHC<6 ppmv have been maintained at 100 percent load for over 3700 hours of operation on the utility grid. The turbine continues to operated 24 hours a day, 7 days per week with commercial levels of unit availability.

The goal of the Advanced Turbine Systems (ATS) program is to develop a high thermal efficiency industrial gas turbine with ultra-low emissions (<10 ppmv NOx, CO and UHC @ 15% O2) over the 50 to 100% load range. Catalytic combustion was chosen as an approach likely to meet ATS emissions goals. A subscale catalytic combustor development program was designed to develop a technical knowledge base for catalyst design (catalyst construction, length), performance (ignition, activity and emissions) and operating limitations (fuel-air turndown and sensitivity to combustor operating variables). A novel catalyst design with preferential catalyst coating to limit substrate temperatures was used in the tests. The catalytic combustor consists of a fuel-air premixer, catalytic reactor and a post-catalyst zone for completion of homogeneous gas phase reactions. In situ measurements of mean fuel concentrations at the exit of the premixer were completed to characterize fuel-air premixing levels. Performance of the catalyst was monitored through global emissions measurements at the exit of the post-catalyst combustor under simulated engine conditions, and measurement of catalyst substrate temperatures. Ultra-low emissions were achieved for relatively uniform fuel-air premixing (<10% peak to peak variation in fuel concentration) with higher inhomogeneities (>10% peak to peak variation) leading to either locally high or low substrate temperatures. Regions with low substrate temperatures led to high CO and UHC emissions. Modeling of post-catalyst homogeneous reactions using a standard stationary, one-dimensional, laminar premixed flame formulation showed good agreement with measurements. In short term tests, the catalysts showed the desired chemical activity and ability for multiple light-off. The subscale combustor development work provided the necessary technical information for full scale catalytic combustion system development for the ATS gas turbine.

Dynamometer Test

Combustor hardware employing catalytic combustion technology has been developed for a 1.5 MW gas turbine. This system, combined with state of the art catalyst technology, was used to demonstrate ultra-low emissions on the engine. The demonstrator combustor utilizes a two stage lean premix preburner system to obtain the required catalyst inlet temperatures and low NOx over the operating load range. The performance of the preburner system was characterized during engine tests by measuring temperature rise and emissions just downstream of the preburner. A fuel schedule for the primary and secondary stages was selected to give NOx emissions below 2 ppmv at the engine exhaust. Overall engine performance was measured over the full load range. Emissions of NOx < 3 ppmv and CO and UHC < 5 ppmv were obtained at 72% to 100% load. Combustor dynamics were shown to be less than 0.3 psi(rms). This combustor operated for 1000 hours on a dynamometer test facility and showed low emissions performance over this period.

ALSTOM’s new gas turbine, the GT10C, is a 30 MW industrial gas turbine for mechanical drive and power generation, which has been upgraded from the 25 MW GT10B. The thermal efficiency of the new gas turbine is 37.3% at ISO inlet conditions with no losses. The GT10C features a dual-fuel dry low emission gas turbine, with emissions values of 15 ppm NOx on gaseous fuel and 42 ppm NOX on liquid fuel (also dry). The GT10C was first started and operated on load in November 2001 and the test program is ongoing until the fall of 2002. The program covers a complete package test, including gas turbine, auxiliaries and control system, to ensure package availability. For the tests, a new test rig has been built in Finspong, Sweden, for testing on both natural gas and liquid fuels. The tests have been very successful, achieving the product targets, for example below 15 ppm NOx, without combustor pulsations. This paper discusses operation experience from the test rig, where the engine has been tested on both natural gas and liquid fuel over the whole load range. The engine has been equipped with over 1200 measuring points, covering the complete gas turbine. All critical parameters have been carefully verified in the test, such as turbine blade temperature and stresses, combustor temperatures and dynamics and engine performance. Results from the tests and measurements will be discussed in this paper. Performance and emissions will also be evaluated.

The first part of this paper describes the test facility to characterize the catalytic combustor. The combustion chamber is a LPP combustor (Lean Premixed Prevaporised), made of preheater, premix duct, catalytic part and after burner. Each component will be validated separately for the required conditions (steady state and transient conditions). All the measurements and data acquisition are described. The second part deals with the test facility for the hot spin test of the ceramic wheel. The base of the test bench is a modified turbocharger (maximum rotating speed: 125000 r.p.m.). With this configuration it will be possible to test the ceramic radial wheel within the AGATA specifications; in this case the compressor is used like a brake. The last part is devoted to two ceramic heat exchanger test rigs: the first rig is to evaluate the themomechanical stresses on the samples; the second rig to assess the performance compared to the AGATA specifications and to duplicate the transient and thermal shock conditions. In this program the heat exchanger is fixed.

Catalytic Combustor

Laboratory tests of catalytic combustors with distillate fuel have achieved ultra low NOx formation at catalytic reactor exit temperatures and combustion efficiencies consistent with state-of-the-art gas turbine requirements. Concomitant with these features, however, are design limitations such as narrow turn down range and unique reactor mounting requirements. This paper presents fully analyzed conceptual design solutions to these problems within the constraints of fixed geometry, full catalytic combustion over 80% of the turbine load range, and retrofit to an existing gas turbine. The combustor design incorporates (a) a gutter stabilized pilot burner downstream of the reactor for operation from ignition to full speed no load, (b) a segmented fuel-air preparation system for fuel staging of the reactor, (c) a reactor mounting system which accommodates thermal growth and start-up and shutdown transients, and (d) a graded cell reactor. These features were achieved while maintaining low reactor face velocities and system pressure drops.
