This is a device that is used to produce very large volumes of very cool gas. This is similar to the solid rocket or liquid rocket. When the temperature is lowered this will allow the gas to be used more easily in many applications, this is most used to run turbines.
This is used in the turbopumps of the rocket motors; this will help to deploy airbags in this pressurized gas is undesirable, but large volumes of gas is needed.
Gas Generator Cycle
This is usually referred to the design the turbopump-fed liquid engine. In this, the propellant is burnt to drive the turbopump. The exhaust is thrown overboard and this is done through a nozzle. In other generators this is fed into the combustion chamber and the propellants are burnt within a fuel rich mix, this is done to keep the temperatures low.
Open Cycle
This is the power cycle of any bipropellant rocket engine. A part of the propellant is burnt in the gas generator which emits hot gas and this is used to power the engine’s pumps. The gas that is emitted is then exhausted.
This being the case the hence the engine is referred to as the open cycle.
Uses
- There are many automobile companies that buy gas generators as they can be used in the automobile air bags. A very small pyrotechnic charge is used to open the value which will result in the gas generation process.
- This is also used in the chemical oxygen generator.
- Another very important use of the gas generator is the power torpedoes. In other cases hydrogen peroxide is used.
- This is also used in the powering of the auxiliary power units and also in the emergency power units.
Disadvantages
Though with all the advantages one of the main disadvantages of the gas generator is that it will lose its efficiency when the propellant is discarded. These cycles have a lower specific impulse than any of the staged combustion cycles.
Advantages
When compared to the staged combustion cycle, the gas generator cycle will not have any problem with the pressure of injecting the exhaust into the combustion chamber. This will make the engine less expensive and the also the weight of the engine will be very low. The plumbing and turbine design are simplified with this generator. The fuel in this cycle is used to cool the nozzle and the combustion chamber.
Buy gas generators for very specific applications like coal seam methane like well gasification, head drives, land fill applications and digester. This is used to convert the heavy duty diesel engine into spark ignited. These generators are built to run 24/7 at the base load application. This is more commonly used with the natural gas application, which is used for the green star building; this will utilize the co-generation and tri-generation. These are the reasons to buy gas generators. The renewable sector has also the ability to use these gas generators in many of the applications.
There are companies that have expertise which is used to manufacture and install the packages according to the applications. When determining the company to buy these gas generators, a person will need to ensure that the machine is cost effective and well-engineered. This is an environmental solution and will reduce carbon footprint when one decides to buy gas generator.
