The generation and distribution of diesel emissions from generator sets are closely related
Effects of nitrogen oxides, smoldering HC, and carbon (soot) on premixed combustion and smoke diffusion or mixing to control combustion phase formation. Nitrogen oxides are generated in the high-temperature gas region, but due to the uneven temperature and combustion space distribution in the combustion area.
The yield of nitrogen oxides should be near the stoichiometric value. The carbon particles are generated near the thick mixture of gas layers and the core of the oil bundles, and then oxidize to a yellow flame when they encounter air.
At present, PAHs or carbon black are carcinogenic factors, and some controversies still exist. Due to the large amount of air burning in supercharged diesel engines, the main harmful emissions are nitrogen oxides and PM, and the others are small.
In the power generation industry throughout China, we have been working hard, pursuing the concept of quality and service, and at the moment of thinking for customers. Full power generators choose China, your professional housekeeper of generators. After the exhaust gas of the generator set is discharged, the generator set should be cleaned in time to avoid unnecessary losses caused by the accumulation of emissions.
- Blue smoke, fire reason: It means that the engine is burning oil. There are three types of reasons: first, the piston ring goes opposite, and the oil comes in the cylinder; the second is the oil level of the oil pan of the atmosphere filter, which leads the ring. The height of the groove; Third, the gap between the duct and the valve stem is too poor. Expulsion idea: Adjust the piston ring so that the opening teeth of the ring are staggered 120 degrees or 180 degrees, and the opening teeth of the ring should avoid the piston pin hole and the side pressure is poor. Adjust the height of the oil level of the oil filter of the atmosphere filter below the height of the annular groove; if the clearance between the duct and the valve stem is too poor, replace the component and reduce the clearance. The normal mutual assistance clearance between the two is 0.0
- In the power generation industry in China, we have been working hard, pursuing the concept of quality and service, and for the sake of customers, the full power generator chooses China and your generator is a professional housekeeper. At present, the diesel generator set maintenance market refers to damage inspection and routine maintenance. Two aspects: after maintenance refers to the failure of the diesel generator, there are problems with various accessories, such as replacing the generator or
- Before starting, you should check whether the fuel volume of the fuel tank is rich, and there is no oil leakage in each oil pipe and the discussion area; whether the cooling system water is rich, clean and leak-free, and whether the fan belt is tight or not. The internal combustion engine and generator drive parts should be connected and trusted. The wires of the input line are well-insulated, complete and effective in all aspects. After starting, it should run at low speed for 3 to 5 minutes. After the temperature and oil pressure wheel are normal, the initial work can be done. The generator should be no different in the speed increase. Ring, the slip ring and commutator are well brushed, no jumping and sparking phenomenon. After the operation is stable and the frequency and voltage reach the rated value, power can be supplied to the outside.
- The diesel engine is working normally, but the generator fails to generate electricity or the voltage is very low. This may be due to the components associated with the generator, such as: the exciter is damaged, and the excitation voltage cannot be supplied. The excitation current is taken in. The rotor's dead center residual magnetism is weakened or declining. It will make the generator unable to generate electricity or the transmission voltage is extremely low. The right to respond is usually: use an appropriate DC voltage and directly connect to the excitation winding according to the polarity Magnetization. Carefully inspect the exciter and the cyclotron rectifier, find abnormal components or windings, and replace them for restoration. The generator's transmission voltage is unstable, and
