What are the causes and solutions for white smoke from diesel heaters?
2 Answers
Diesel heaters emit white smoke due to poor ventilation and insufficient density of compressed fuel. A larger volume of fuel is required to release a certain amount of heat, and when the internal space of the diesel heater accommodates fuel beyond its rated capacity, the ventilation or oxygen supply becomes severely inadequate. Under conditions of insufficient oxygen supply, the compressed diesel fuel cannot burn fully or cannot burn completely in a short time, leading to the situation where smoke is produced without ignition. The solutions for white smoke from diesel heaters are: 1. Reduce the amount of fuel placed at one time; 2. Improve the ventilation system by appropriately increasing the size of the vents; 3. Adjust the fuel injection timing.
White smoke from diesel heaters is a common issue, usually caused by condensation vapor during diesel combustion. Imagine this: in winter when temperatures are low, the heater just starts up, and if the fuel isn't fully burned, white smoke is emitted. When I repair these, I've found the key is to check the fuel system: unclean fuel, clogged filters, or water mixed into the diesel can all easily cause white smoke. The solution? Start with the basics—ensure you use clean diesel when refueling and avoid old fuel. Preheat for more than 5 minutes before starting to let the system warm up thoroughly before heating, which can reduce smoke. If white smoke persists, replacing the filter or cleaning the exhaust pipe can greatly improve the situation. Regular maintenance is also crucial; check it every season to prevent small issues from becoming big ones. By the way, don't rush to replace the equipment—most problems can be handled yourself, saving both money and hassle.
