CAN COMBUSTION CHAMBER [13 fiches]

Fiche 1 2017-09-15

Anglais

Subject field(s)
  • Engines (Motor Vehicles)
  • Anti-pollution Measures
CONT

Downsizing is a simple concept; replace a larger engine with a smaller version, with a lower displacement. The downsized engines of tomorrow will have fewer, smaller cylinders, so the volume swept by pistons as they pump up and down inside is reduced. This will reduce friction, thermal losses and the mass moved, boosting fuel economy and cutting carbon dioxide emissions.... Despite having a lower displacement, the performance of a downsized engine can be maintained by injecting more air into its combustion chamber to burn additional fuel. This is made possible by turbocharging...

Anglais

Subject field(s)
  • Anti-pollution Measures
  • Climate Change
CONT

Oxyfuel combustion. An alternative is to burn the fossil fuel in pure or enriched oxygen. In such a fashion the flue gas will contain mostly CO2 and H2O. A part of the flue gas needs to be recycled into the combustion chamber in order to control the flame temperature. From the non-recycled flue gas, water vapor can be readily condensed, and the CO2 can be compressed and piped directly to the storage site.

DEF

Procédé de combustion pour la production d'énergie, dans lequel on utilise comme comburant, à la place de l'air, de l'oxygène pur.

CONT

Le principe de l'oxycombustion [...] utilise de l'oxygène pur comme comburant - Cette technologie n'est pas à proprement parler une capture du CO2. Il s'agit de produire une fumée concentrée à 90 % de CO2 en réalisant une combustion à l'oxygène pur. Avec un recyclage d'une partie du CO2 en substitution de l'azote de l'air, l'oxycombustion est adaptée à une remise à niveau des installations existantes.

OBS

L'oxycombustion permet d'obtenir un flux de dioxyde de carbone (CO2) exempt d'azote, plus facile à récupérer et à conditionner pour le transport et le stockage. Elle fait partie des procédés dits du «charbon propre».

  • Thermoelectricity and Thermoelectronics
CONT

We are deeply involved in cogeneration plants including biomass and gas turbines. ... Co-Generation Power Island. .... "Power Islands," "Merchant Plants," "Across the Fence Cogeneration," "Third Party Steam Plants," and "Client CHP" are some of the names used to refer to unconventional commercial arrangements for the production and procurement of steam and electrical power to pulp and paper mills. Although the term "Power Island" is often used to describe third party cogeneration facilities, the concept is completely different from an island. The power house that provides the steam and power to the mill has a direct and immediate effect on the pulp mill’s operational stability and uptime as well as the operating costs.

CONT

The IGCC [Integrated Gasification with Combined Cycle] demonstration plant in Puertollano features many advantages compared to conventional coal fired power stations with flue gas desulphurization(FGD) and DeNOx systems :... The plant consists of the following three main units : Power island, gasification island, and oxygen production plant(Air Separation).... The power island. The combined cycle in the Puertollano plant... can be operated both with natural gas and synthesis gas. The main features are : A 200 MWe(ISO) Siemens model V94. 3 gas turbine. A three-pressure level and IP steam reheating heat recovery steam generator designed by Babcock able to additionally superheat the steam generated through raw gas cooling in the gasification. A two casing reheat steam turbine designed by Siemens that delivers roughly 135 MWe. The clean coal gas is burned by the coal gas burners in the combustion chamber of the gas turbine. The sensible heat of extracted air is used for clean gas saturation, low pressure steam production and preheating of impure nitrogen. [Text accompanied by a schematic diagram. ]

CONT

The liberalization of the energy market is demanding more-efficient power plants using cheaper fuels. ... The first option ... is to convert old oil- or existing gas-fired power plants to new combined-cycle power plants. The second option is to convert old oil- or existing gas-fired units to efficient and environmentally friendly power plants that burn cheaper fuels, using the best available technology for the power island and the flue gas treatment equipment.

PHR

Power island turbine generator.

Fiche 4 2007-08-03

Anglais

Subject field(s)
  • Burners and Steamfitting
CONT

A floating flame is an indication that there is a lack of secondary air to the flame. In severe cases, the flame will leave the burner and have the appearance of a floating cloud. Again, the intermediate products of combustion are apt to escape from place to place wherever sufficient air for combustion may be found. This flame is sometimes hard to detect because, as the door to the equipment is opened sufficient air will be admitted to allow the flame to rest on the burner properly. However, the obnoxious odor of aldehydes may still be detected. Another possible cause of this flame is an improperly operating vent system. If the products of combustion cannot escape, fresh air cannot reach the flame

CONT

When a flame raises off the burner it is important to determine if it is a "lifting flame" or a "floating flame" :"Lifting Flames" rise from the ports to burn some distance above the ports. In some cases these flames will drop back to the port and lift again intermittently. They are caused by too much primary air. Decreasing the shutter opening will stop lifting flames. "Floating Flames" are long and lazy looking, poorly defined, quiet flames which roll around the combustion chamber sometimes completely off the ports. Floating flames result from too little secondary or "make up" air. Lack of secondary air can be caused by incorrect venting, clogged flueways, blocked secondary air inlet openings, or lack of natural room makeup air to the oven.

OBS

Direct injection(DI) refers to fuel injected directly into the combustion chamber above the piston. Direct injection has long been used on large diesel engines. Smaller diesels are increasingly adopting direct injection(vs. indirect injection into a pre-chamber). Direct injection also can be used in spark ignition(generally gasoline) engines instead of port fuel injection-for cleaner emissions, increased full throttle power and potentially for lean-burn operation.

Subject field(s)
  • Spacecraft
CONT

A rocket engine is a device in which propellants are burned in a combustion chamber and the resulting high pressure gases are expanded through a specially shaped nozzle to produce thrust. The function of the nozzle is to convert the chemical-thermal energy generated in the combustion chamber into kinetic energy. The nozzle converts the slow moving, high pressure, high temperature gas in the combustion chamber into high velocity gas of lower pressure and temperature. Gas velocities from 2 to 4. 5 kilometers per second can be obtained in rocket nozzles. The nozzles which perform this feat are called DeLaval nozzles(after the inventor) and consist of a convergent and divergent section. The minimum flow area between the convergent and divergent section is called the nozzle throat. The flow area at the end of the divergent section is called the nozzle exit area.

CAN COMBUSTION CHAMBER. The can combustion chamber is used mainly on older centrifugal compressor engines. Airflow is ducted to individual combustion cans that are arranged around the circumference of the burner section. Each can contains its own fuel nozzle, burner liner, and casing. Advantages include its strength and durability, combined with the ease of maintenance. Disadvantages include poor use of space in the chamber, greater pressure loss, and uneven heat distribution to the turbine section.

CONT

Most modern space heaters are controlled combustion or airtight designed. The flow of air into the combustion chamber is regulated almost exclusively by controls such as screw-in draft caps or thermostatic control units. These devices allow greater control over the rate of combustion and, therefore, the heat output... Airtight space heater can be fabricated from continuously welded heavy gauge steel..., from thin sheet metal with cast iron or firebrick liners.

Burner Efficiency Tests and Adjustments... A smoke spot tester is used to measure the soot content of flues gases. The serviceman will adjust the air intake band on the burner until a visually smokeless flame is produced in the combustion chamber. The probe of the smoke testing apparatus is inserted through the hole in the flue pipe and a flue gas sample is drawn through a piece of filter paper. The resulting soot mark on the paper is compared in intensity to a standard chart. The chart shows measurements labelled 0 to 9 and most residential oil furnaces can burn cleanly enough for a 0 to 1 rating... a number 2 smoke is ideal.
