- Formation of layer of scales on the furnace wall at the water side can cause overheating and bulging defect on the furnace shell.
- Bulging in water tube is due to calcium scale deposition on tube walls which cause improper heat transfer.
- In smoke tube due to carbon deposits bulging is caused.
- Low water level in boiler.
- Misalignment of burner can cause overheating which will further cause bulging.
