Gas-fired boilers, if they strictly carry out various operations in accordance with the operation requirements and regularly check and maintain, will greatly reduce the problems in the operation process, the service life can reach 15-20 years, and the cost-effective ratio will be higher.
Corrosion is an important factor affecting the service life of boilers. If the boiler is corroded due to operator's errors or failure to maintain on time, it will make the thickness of the boiler body thinner, reduce the thermal efficiency and shorten the service life.
There are two main reasons for corrosion of gas-fired boilers: flue gas corrosion and scale corrosion. This kind of corrosion is accumulated over time. If we don't pay attention to it, it will cause damage to the equipment, and serious accidents will occur. Today, Shandong Gas Boiler Factory will elaborate on the causes of corrosion of gas boilers, so that we can start from the causes and stop the occurrence of corrosion.
1. Flue gas corrosion
The primary cause of boiler corrosion is flue gas. Boilers need fuel to burn, and the combustion process will inevitably produce flue gas. When high-temperature flue gas passes through the boiler wall, condensation water will seriously corrode the metal surface.
2. Scale corrosion
Another main cause of boiler corrosion is scale corrosion. For example, if we use a kettle for daily boiling water for a long time, there will be scales inside the kettle. First, it will affect the quality of drinking water, and secondly, it will take longer to boil a kettle. Boiler is a huge thing hundreds of times larger than kettle. If there is corrosion, it will be very harmful.
Therefore, it is suggested that enterprises using gas-fired boilers should choose standard and reliable manufacturers when choosing and purchasing gas-fired boilers, and the water used by boilers must also be softened, so as to ensure the safe production of boilers and make them more durable.
