Product Specifications

Technical details and manufacturing context for Combustion Chamber (for gas turbines)

Definition
The combustion chamber is a critical component within gas turbine engines (prime movers) where the combustion process occurs. It receives high-pressure air from the compressor, mixes it with injected fuel (typically natural gas, diesel, or aviation fuel), and facilitates controlled ignition and combustion. The resulting high-temperature, high-pressure gases expand through the turbine section to generate mechanical power. Modern designs focus on achieving stable combustion, high efficiency, low emissions (NOx, CO), and durability under extreme thermal and mechanical stresses. The chamber operates under demanding conditions, with inlet temperatures ranging from 300–600°C and exhaust temperatures reaching 800–1200°C. Operating pressure is typically 1.0–1.6 MPa, and the air-fuel ratio is maintained between 40–60 to balance efficiency and emissions. Combustion efficiency is high, at 99.0–99.9%, while pressure drop is kept low at 2–5% to preserve cycle efficiency. Fuel flow rates vary from 0.5–5.0 kg/s depending on turbine power rating. Materials commonly used include nickel-based superalloys, cobalt-based superalloys, ceramic matrix composites (CMCs), and heat-resistant steels. A typical material grade is Inconel 718, conforming to ASTM B637. Wall thickness ranges from 2–5 mm, and the component weight is between 50–200 kg. Service life is influenced by thermal cycling and maintenance, typically 20,000–50,000 hours. For procurement, verify model-specific values and standards with the legal manufacturer or supplier.
Working Principle
Compressed air enters the combustion chamber through swirlers or dilution holes to create a recirculation zone for flame stabilization. Fuel is injected via nozzles, atomized, and mixed with air. Ignition (initially by spark plugs, then self-sustaining) raises the gas temperature to 1500–2000°C. The combustion gases accelerate toward the turbine inlet while maintaining pressure. Cooling techniques (film cooling, impingement cooling) protect chamber walls from thermal damage.
