“…However, a preburner is typically needed to raise the gas inlet temperature to a level required for catalytic ignition. Owing to material stability limitations and the steady increase in the gas turbine combustion temperature ($1400 C in modern machines), original concepts with complete combustion in the catalytic module [32] were soon abandoned in favor of the CST alternative of Figure 8.1a.…”

“…These experiences lead to consider that a leanpremixed combustion and a catalytic combustion are the most promising technology for burning natural gas. However, the catalytic combustion will not be able to be commercialized in the near term because of the short life of the catalyst (Kajita, et al, 1990). Consequently the combustor used in the development program was designed based on the concept of lean-premixed combustion.…”

To meet strict NOx regulations, Kawasaki Heavy Industries, Ltd. has been conducting a development program of dry, low-NOx combustion system since 1989. In a first step of the development program, a multi-burner type, can combustor has been developed. The test engine, with an output of 1.5 MW, demonstrated NOx emissions below 42 ppm at 15% O2. Following the engine performance tests, a 500 cycle endurance test and a 300 hour test at full load have been conducted to assess the reliability of the combustion system developed. During these tests, no mechanical durability issues arose.

“…Several groups have tested catalytic combustion systems on gas turbine engines. Kajita and coworkers reported the development and engine demonstration of a catalytic combustor for a 170 kW Kawasaki S IA-02 gas turbine (ICajita, 1990;Kitajima, 1989;Hoshino, 1987). This combustor was operated on a gas turbine for 200 hours at full load.…”

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.
