Winter is officially here! When cold weather settles in, it is important to make sure that your boiler is well-maintained. Like any other mechanical system, boilers will tend to wear down over time. Boilers can be dangerous if not properly inspected and not working properly. Full boiler efficiency will help avoid boiler downtime and unnecessary expenses. Here are 14 steps to follow to help you get on track with your winter maintenance:
1. Inspect the fuel source.
The fuel used needs to have the proper viscosity for atomization. Test and gauge the fuel viscosity to ensure full efficiency.
2. Inspect the fireside.
Inspect the fireside and look for any indication of corrosion. If no corrosion is found, continue to clean the fireside and the furnace area as necessary.
3. Check the refractory.
Due to the cooler weather, be aware of thermal expansion. Boiler refractors are designed to expand and contract with temperature changes. But all boilers will incur some cracking due to those constant changes. If excessive cracks are found, repair as needed.
4. Inspect the waterside.
Inspect the waterside of the boiler for scale and remove as necessary. Scale prevents heat transfer inside the boiler and can significantly lower efficiency. All water-level controls need to be properly inspected, opened, and cleaned.
