Considering the definition of combustion chamber used for internal combustion engines, the equivalent part of a steam engine would be the firebox, since this is where the fuel is burned. [citation needed] However, in the context of a steam engine, the term "combustion chamber" has also been used for a specific area between the firebox and the ...
Its combustion chamber was lined with a thin copper sheet supported by the corrugated steel wall of the chamber. Fuel flowed through the corrugations and absorbed heat very efficiently. This permitted more energetic fuels and higher chamber pressures, and is the basic plan used in all Russian engines since.
A countercurrent heat exchanger with forced cooling air does the job. The cylinder-walls should not heat up the air before compression, but also not cool down the gas at the combustion. A compromise is a wall temperature of 90 °C. The viscosity of the oil is optimized for just this temperature.
Uniform exit temperature profile. If there are hot spots in the exit flow, the turbine may be subjected to thermal stress or other types of damage. Similarly, the temperature profile within the combustor should avoid hot spots, as those can damage or destroy a combustor from the inside. Small physical size and weight.
Some fireboxes were equipped with a so-called combustion chamber, this is a distinct component from the firebox and tubes - a large single extension of the firebox space, into the boiler barrel, and above the brick arch and separated from the grate and the fire bed, this placed additional space between the fire and the rear fire tube/flue sheet.
The furnace remains a single large-diameter tube with the many small tubes arranged above it. They are connected together through a combustion chamber – an enclosed volume contained entirely within the boiler shell – so that the flow of flue gas through the firetubes is from back to front.
Internal combustion engines can contain any number of combustion chambers (cylinders), with numbers between one and twelve being common, though as many as 36 (Lycoming R-7755) have been used. Having more cylinders in an engine yields two potential benefits: first, the engine can have a larger displacement with smaller individual reciprocating ...
The highest temperature in the engine (about 3,700 °F (2,040 °C) [9]) occurs in the combustion chamber, where fuel is burned (at an approximate rate of 8,520 lb/h (3,860 kg/h)) in a relatively small proportion of the air entering the engine.
