Question 1 of 27070

The short length of the can-annular combustion chamber provides for which of the following conditions?

🔍 Key Concepts

• Gas turbine combustor design and how flow path length affects pressure drop • Difference between pressure in the gas path and temperature rise from combustion • What a can-annular combustion chamber is compared with a simple can combustor

💭 Think About

• If gases travel a shorter distance between the compressor outlet and the flame area, what usually happens to friction and losses? • Does simply shortening the physical length of the combustor, with the same fuel/air ratio, automatically raise or lower the flame temperature? • In a well-designed turbine combustor, is the goal usually to waste pressure or to preserve as much of it as possible for the turbine?

✅ Before You Answer

• Be clear whether the question is asking about pressure behavior, not temperature behavior • Think about how flow length influences pressure drop in any duct or pipe • Ask: Is the design intent of a short can-annular combustor to achieve more loss or less loss between compressor and turbine?

Question 1 of 27070

The short length of the can-annular combustion chamber provides for which of the following conditions?

Increased combustor temperature.

Maximum pressure drop of the gases between the compressor outlet and the flame area.

Decreased combustor temperature.
