To reduce pollutant emissions, users must pay attention to the use and maintenance of diesel generator sets

As we all know, diesel generator sets will emit a certain amount of pollutants during the operation process. For the emission standards of pollutants, the State Environmental Protection Administration of my country has also formulated relevant national emission standards. In addition to strictly complying with emission standards in the production process, users In the process of use, some corresponding measures and correct maintenance of the unit can also be used to reduce the emission of pollutants.

 

       As we all know, diesel generator sets will emit a certain amount of pollutants during the operation process. For the emission standards of pollutants, the State Environmental Protection Administration of my country has also formulated relevant national emission standards. In addition to strictly complying with emission standards in the production process, users In the process of use, some corresponding measures and correct maintenance of the unit can also be used to reduce the emission of pollutants. Let's take a look at the specific ones.

 

       1. Reasonably select the common working conditions of diesel generator sets. The operating conditions (load and speed) of the diesel generator set directly affect the content of harmful components in the exhaust gas. For diesel generator sets used in underground operations, the working condition with lower pollutant discharge and better power and economy should be selected as the common working condition; when there is a conflict between the emission index and the power and economy index, the less sewage should be selected , and the working condition with less dynamic and economic losses is the common working condition. This is one of the measures currently taken to meet emission standards. When selecting operating conditions, a comprehensive understanding of the emission characteristics of diesel generator sets should be obtained. Using the exhaust emission characteristic curve, it can be avoided to use in some heavy pollution conditions to obtain better exhaust gas quality. In addition, the idling time of the diesel generator set should not be too long (generally no more than 15min) to reduce pollution.

 

       2. Reduce power usage. Diesel generator sets reduce the use of calibrated power, which can reduce the fuel injection amount in the calibrated working condition, which can not only reduce the exhaust smoke, but also reduce the emissions of CO, HC and NOx, but the fuel consumption rate will increase. At present, there is a trend of reducing the use of calibrated power on underground diesel generator sets abroad. Therefore, the underground diesel generator set should have sufficient power reserve and torque reserve, and the general power reserve should be more than 15%, that is, under various operating conditions, the diesel generator set should be below the limit of smoke emission and the pollutant emission is relatively high. Work in the low power section, sometimes sacrificing part of the power performance and economic performance to reduce pollutant emissions.

 

       3. Strengthen the maintenance of diesel generator sets. When diesel generator sets are operating in tunnels and underground works, attention should be paid to regular inspection and maintenance of diesel generator sets to keep diesel generator sets in good technical condition and reduce exhaust pollution to the operating environment. Therefore, diesel generator sets should have a strict maintenance system. In addition to the regular inspection of "three leaks" (leakage of fuel oil, lubricating oil and gas), the maintenance of the diesel generator set air intake system, oil supply system, lubrication system, cooling system and exhaust gas purification system should also be strengthened.

 

       Through the above precautions for the use and maintenance of diesel generator sets, the pollutant emissions of diesel generator sets can be effectively reduced. It is worth mentioning that the current diesel generator sets on the market are divided into National II and III, and III diesel power generation. The unit has lower emissions and lower fuel consumption. Tingbo Power hopes that everyone can purchase diesel generator sets in strict accordance with the national emission standards for the health of our living environment.
