Reference Answer
An increasing daily consumption of auxiliary boiler feed water, without a corresponding increase in steam demand, is a clear indication of a progressive loss or malfunction within the boiler, steam, or condensate systems. A systematic and logical diagnostic approach is required to identify the root cause. The potential causes can be categorized into internal losses, external losses, operational faults, and control system malfunctions.
### Potential Causes for Increased Feed Water Consumption
#### 1. Boiler Internal Leakage
This refers to the loss of water from the water/steam side into the combustion/gas side of the boiler.
