Sparks are caused by the combustion of carbon powder. And why is there diesel but toner? Because of carbon deposits. The causes of carbon accumulation are diverse. And how can we avoid carbon accumulation? This is not only related to the state of charge, the quality of the fuel, but also the quality of the unit itself and the quality of the fuel system tuning. For example, long-term light loading can cause carbon buildup. If you idle for a long time, the risk of carbon buildup is high. etc.
How to clean carbon deposits? Of course, it is best to have professionals take it apart, inspect it and maintain it. Sometimes you can increase the load, which is equivalent to stepping on the accelerator, and sometimes you can eliminate some carbon deposits.
Why are the two portable gasoline generators catching fire?
This and other generator tips: This situation is mainly because your generator may be overloaded!
Causes of chimney fires in gasoline generators
Chimney fires in gasoline engines are usually caused by unburned fuel or oily deposits coming out of the chimney with high temperature gas and then burned. in the air, that is, the continuation of the fuel combustion process in the cylinder. Let’s take a look at the detailed explanation from generator accessories manufacturer Sardon.
1. Sparks formed by burning oil mist are difficult to detect during the day, but small, short light pink sparks can be seen coming out of the chimney at night. Most of the sparks go out in the stream of smoke that follows them, without any carbon or black particles falling. This situation often occurs when the enginegasoline engine is overloaded, the fuel atomization in some cylinders is poor or the air supply to the cylinder is insufficient. The fuel injected into the cylinder cannot be completely burned and there is excessive oil mist or fine oil droplets. in the cylinder are evacuated by the high temperature. When gas is fed directly out of the chimney, it burns when it encounters oxygen.
2. Sparks formed by burning residual oil. These sparkles are slightly longer in shape and darker in color than those above. They rush into the sky from the chimney and drift with the wind before dying out. fine carbon particles and soot ribbons. This usually occurs when some injectors in a gasoline engine drip oil or have poor combustion during low load operation. Especially when the temperature and pressure of the soyexhaust system are low for a long time, unburned oil often accumulates in the exhaust pipe, even if. he is carried away. It is also difficult to be ignited by low temperature gas when it comes out of the chimney. Some old gasoline engines use the boiler exhaust gas bypass method to vent the gas directly to avoid contamination of the heating coil in the boiler. On modern ships, most bypass smoke exhaust pipes have been removed. The gas can only be discharged through the exhaust gas boiler, and the exhaust back pressure increases. Therefore, the accumulation of oil in the flue of a two-stroke gasoline engine operating at low load will gradually increase. The accumulated residual oil has undergone a physical and chemical preparation process before ignition. If there is sufficient air, when the tExhaust temperature is higher than 210°C or an open flame is encountered, it will catch fire at the outlet of the chimney inside the exhaust. pipe.
3. Sparks formed by the combustion of soot deposits. Most sparks emitted from the chimney are plate-shaped. Sparks usually occur shortly after travel and 10 to 15 days after travel, and the flame duration varies from half an hour to three hours. During the day it is not noticeable because of the light, but at night it is very shocking. This type of sparkle has a large bright spot, is black and red, and lasts a long time. Ashes and solid particles of different shapes come out of the chimney with the spark. They often fall onto the deck and continue to burn. which can easily cause a fire.A fire has broken out. Generally speaking, in the exhaust system, there is little fire in the channel sectionization going from the compressor outlet to the exhaust gas boiler inlet, and there is not much soot on the superheated steam coil of the exhaust gas boiler. However, dense heating fins are often found on saturated steam coils and numerous solid deposits on the funnel-shaped parts of exhaust gas boilers. These deposits are the main source of sparks.
Here are the reasons for chimney fires from gasoline generators. I hope this information can be useful to you. Below we will focus on preventive measures and solutions:
Gasoline Generator Set Chimney Fire Preventive Measures:
1. Maintain combustion in the cylinder of the gasoline engine in good condition
2. Strengthen monitoring of the combustion process of each cylinder; detect abnormal conditions in time;
3. To strenghtenmanagement of boiler exhaust gases to maintain good combustion effects;
4. Put suitable carbon remover and other chemicals into the tailpipe or exhaust; gas boiler regularly, in order to prevent scale and clean the system, carbon deposits on the pipe wall can be softened, removed and even burned after lowering the ignition point
5 . the tanker, the chimney is equipped with a sprinkler fire extinguishing device.
Emergency treatment for gasoline generator chimney fire
1. If the first type of spark occurs, immediately reduce the load on the gasoline engine or slowly stop it, find the cause and eliminate it. the fault before continuing. Use it, then increase it to the required load once the smoke evacuation is normal.
2 If the second and third types of sparks appear, eThey must be allowed to continue “spraying”. if the environment permits, so that the exhaust gas blows and burns the oily deposits in the system as much as possible, but the maintenance management and fire prevention work of the gasoline engine and gas boiler exhaust must be reinforced;
3. In addition to excessive fire, individual cylinders or local exhaust pipes should be reduced to overheat off-speed, the gasoline engine should operate at high load as much as possible; >4. Do not use fire extinguishing equipment, especially CO2 fire extinguishing equipment, to prevent high temperature metal from exploding due to a sharp drop in temperature.
