What is Combustion chamber: Definition and 20 Discussions

A combustion chamber is part of an internal combustion engine in which the fuel/air mix is burned. For steam engines, the term has also been used for an extension of the firebox which is used to allow a more complete combustion process.

    Opening a door between a vacuum and atmosphere

    I work as part of the engineering team running an incinerator. When the ash is removed from our furnace, it creates an open system between the furnace (which is close to being a vacuum) and the atmosphere. For many reasons, this is not ideal. We are looking to add a second door to this ash...

    Questions about energy generation from coal

    Hello : i was watching the news , and it was all about how Europe will start the coal factories again for energy generation had a question related to reduction of coal consumption for energy generation 1 ) could we use coal fine particles instead of chunks of coal that will burn more...

    Increasing the Range of Howitzers

    I think that the range of a howitzer be increased simply by adding more explosive propellant. Why is this not used? I would think that this would be a straightforward way to increase the gun's effective range. Any ideas?

    HVAC Accessible metal product for a combustion chamber

    So I'm still playing with my waste oil heating system, and as I figured the oil spraying out of the burner doesn't burn 100% clean without a combustion chamber. I set it up outside with the burner pointing into a 12" section of 6" steel stove pipe with an elbow on the end, and it works perfect...

    Maximum pressure for a combustion chamber

    Greetings All! I am not sure if this is the correct place to post this, but I think that since rocket fuel is considered a chemical reaction, this sections seems appropriate. Right, to the topic. Me and my team from the spaceflight society are looking forward to building a hybrid rocket fuelled...

    Is the Combustion Chamber Volume for a Lamborghini Aventador Really That Small?

    I was analyzing the Lamborghini Aventador's tech. specs. and it is given Bore x Stroke 95mm x 76.4mm and compression ratio 11.8:1. Then I calculated the volume of displacement and it's 541.5 cm^3 for each cylinder. Then I know the compression ratio as $$\frac{V_1 + V_2}{V_2} = C.R$$ $$...

    Launching a rocket from high altitude

    I have a project where I will be launching a rocket from a high altitude weather balloon. I am planning on launching the rocket at around 70Km or even higher. My main concern is the igniter not being able to ignite the engine because of the low amount of oxygen. Is there any way around this...

    Calculating Temp. in a Heated Vessel: A Problem for Dave

    Hi there, I have a problem that I cannot find a solution too. In this problem I have a fuel (approximately natural gas) supply which is combusted when mixed with air inside a burner. The flame that is then generated is used to heat up a sealed cylindrical vessel (the flame is on the outside of...

    Is this an error in the text? (Gas Turbine Combustion Chamber)

    Hello I am teaching physical science at an online school, and came across this issue in the textbook - I'm looking to double check with more knowledgeable people before I bring it up and potentially make a fool of myself. In one chapter of the physical science text it discusses various...

    Gas Burner and Combustion Chamber Design

    Hi guys, I want to design a gas burner and combustion chamber. I use natural gas as fuel. I want to control air to fuel ration, so air flow has to control. I have an air compressor as air flow source. Clearly, it's needed a mixture tube before the combustion chamber. Now I have some...

    What is the purpose of ignition in a rocket combustion chamber?

    Hi Everyone. I am trying to simulate a rocket combustion chamber. The question I have is this. Is the ignition (by any means) in the rocket combustion chamber only used for increasing the temperature of the cryogenic propellant to a state where it can ignite and burn? If you are using an...

    Would this be possible in a Rocket Engine combustion chamber

    Lets say if i have a bell nozzle rocket engine such as this one : http://www.braeunig.us/space/pics/fig1-04.gif and inside the combustion chamber i have an average pressure of around 300 psi. If i wanted to feed in liquid fuel into it while the fuel pump is only able to supply 100 psi of fuel...

    Designing a combustion chamber (solid mechanics problem)

    Here's my problem: I want to design a cylindrical combustion chamber for a hybrid propelent rocket. Basically, I will burn paraffin and use oxygen as oxidant. As I will be using stainless steel, I thought I could approximate the maximum stress that must be resisted by the material through a...

    Harmonic Dampening inside of a combustion chamber

    Could anyone recommend any literature on harmonic dampening inside of a combustion chamber (augmented injector plates and chamber geometry to reduce vibration)? It seems resources are rather scarce on the subject so if anyone knows of any websites, books, papers, etc. that might be helpful, I...

    Devices that can inject air-fuel mixture into the combustion chamber

    hey, I need all the help i can get on this one... can u guys tell me if there is any device that can be used instead of an ordinary fuel injector since i want it to be able to inject an air-fuel mixture. since the normal injector can't inject air i desperately need another device...

    Heat transfer inside engine combustion chamber

    Hi, I'm not sure if I've got this in the right section, but I'm hoping someone can point me in the right direction. I'm trying to create a model of what's actually happening during the combustion cycle in an engine and where the energy is going. As the intake valve closes and the piston...

    Designing an inline flare gas combustion chamber

    I have built a nice biomass gasifier that produces about 700,000 btu's of heat per hour by burning or flaring the gas that comes out of it. What I want to do is, to flare the gas in an enclosed chamber so I would be able to capture all the exhaust and run it through some heat exchangers for...

    View Windows on a Combustion Chamber

    Does anyone have view windows which they installed on their combustion chamber? My team and I are going to install quartz windows on 304 stainless steel, and so far the coefficients of thermal expansion look really different. We are also debating on the shape of the windows. Any hints would...

    Rocket Engine Combustion Chamber Equations

    Good evening all, I was wondering if anyone would be able to point me in the right direction to equations in regards to designing a proper combustion chamber for a rocket engine, as well as for the throat/De Laval nozzle as well. I've looked around and I can't seem to find anything that...
