When the NGV’s engine is started, natural gas flows from the gas bottle into the fuel hose. Near the engine, the natural gas enters a pressure regulator to reduce the pressure. The natural gas then enters a multi-point gas fuel injection system that directs it into the cylinders. Sensors and computers adjust the fuel and air mixture so that when the spark plug ignites the natural gas, combustion is more efficient.

Classification of Diesel Generator Sets

In addition, according to the purpose and use of diesel generator sets, they can be divided into standby generator sets, common generator sets, war-ready generator sets and emergency generator sets.

Generator Sets

1. Standby Generator Sets

Under normal circumstances, the power required by users is supplied by the city power. When the city power limit is disconnected or other reasons interrupt the power supply, the generator set is set up to ensure the basic production and life of users. This type of generator set is located in important power users such as industrial and mining enterprises, hospitals, hotels, banks, airports and radio stations where the city power supply is tight.

2. Common Generator Sets

This type of generator set operates all year round and is generally located in areas far away from the power grid (or city power) or near industrial and mining enterprises to meet the construction, production and living electricity needs of these places. At present, in areas with relatively rapid emergency development, common diesel generator sets with short construction periods are needed to meet the needs of users. This type of generator set generally has a large capacity.

3. War-ready generator sets

This type of generator set is used to supply power to civil air defense and national defense facilities. It has the nature of a standby generator set in normal times, and has the nature of a common generator set after the city power is destroyed in wartime. This type of generator set is generally installed underground and has a certain degree of protection.

4. Emergency generator set

For electrical equipment that will cause major losses or personal accidents if the city power is suddenly interrupted, emergency generator sets are often set up to provide emergency power to these equipment, such as fire protection systems, evacuation lighting, elevators, control systems of automated production lines, and important communication systems in high-rise buildings. This type of generator set needs to be installed with a self-starting diesel generator set, and the degree of automation is required to be high.

The above are some basic classifications of diesel generator sets. Users can choose suitable diesel generator sets according to their needs and suitable environments. For the use of diesel generator sets, in addition to the correct selection of matching models, regular maintenance is also required in later use.

The first! This generator set was successfully developed

On August 22, the Institute of Electrical Engineering of the Chinese Academy of Sciences learned that after five years of technical research and engineering construction, the first supercritical carbon dioxide solar thermal power generation unit was successfully developed. The third-party test results show that the power generation power, heat-to-work conversion efficiency and other indicators of the generator unit fully meet the requirements of the project task book.

It is reported that the generator unit was developed with the support of the “Research on Key Basic Issues of Supercritical Carbon Dioxide Solar Thermal Power Generation” project. The project recently passed the project performance evaluation organized by the National Natural Science Foundation of China. After five hours of defense and expert questioning, the expert group gave a high evaluation of the project and recommended its promotion and implementation.

In recent years, my country’s solar thermal power generation industry has shown a booming development trend, but the cost of solar thermal power generation has not fallen as expected. Supercritical carbon dioxide solar thermal power generation technology, as the most potential low-cost, high-efficiency and high-flexibility technology, has attracted widespread attention from global research institutions and industries.

“However, the core equipment used in supercritical carbon dioxide solar thermal power generation technology, such as high-temperature particle absorbers and supercritical carbon dioxide generators, are in the research and exploration stage worldwide.” said Wang Zhifeng, project leader and researcher at the Institute of Electrical Engineering of the Chinese Academy of Sciences.

Over the past five years, the project team has focused on engineering design, organically integrated basic theoretical research, technical equipment development and system integration, and actively promoted scientific research and empirical engineering construction.

“We have overcome the difficulties in designing and manufacturing core equipment such as solar high-temperature particle heat absorption, fluidized bed particle/carbon dioxide heat exchange, and 200-kilowatt supercritical carbon dioxide generator sets. We are the first in the world to realize the operation of supercritical carbon dioxide solar thermal power generation systems including high-coke ratio focusing fields, particle heat absorbers, particle/supercritical carbon dioxide heat exchangers, supercritical carbon dioxide compressor turbine units and high-speed motors.” Wang Zhifeng said that the project will effectively promote the development of my country’s “low-cost-high-efficiency-high-flexibility” solar thermal technology and provide technical support for the construction of my country’s new energy bases.
