What Is a Gas Generator?
A gas generator is a device that converts gas into electrical energy, typically functioning as an internal combustion engine. Their advantages include lower fuel costs, a stable fuel supply, high efficiency in electricity generation, and lower CO2 emissions compared to heavy oil or gasoline generators. They can also use biogas for even more eco-friendly operations. However, challenges include higher initial costs and the need for a fuel supply infrastructure. Adequate exhaust and noise control measures are necessary due to combustion by-products.
Uses of Gas Generators
Gas generators are used in various applications and fields, serving in both regular and emergency capacities:
- Regular Use: In factories and power plants for continuous power generation and as a dual source of electricity and heat.
- Emergency Use: In office buildings and shopping malls as backup power sources to ensure uninterrupted operations during power outages.
Gas Generator Principle
Gas generators operate by intaking combustible gases such as propane gas, mixing them with air, and igniting the mixture to produce high-pressure, high-temperature gas. This gas powers rotating equipment connected to a generator, transforming rotational energy into electrical power. Exhaust gas treatment systems are often implemented to minimize environmental impact.
Types of Gas Generators
- Gas Engine Generator: Uses gas expansion to turn an engine, generating electricity efficiently even in smaller sizes. Requires frequent maintenance due to wear.
- Gas Turbine Generator: Employs continuous gas combustion to turn a turbine, known for low running costs and high heat recovery rates, making it suitable for facilities with high heat usage. However, it has lower power generation efficiency compared to engine methods.
