During normal operation of boiler, in order to ensure its safe and economic operation , "Four Kinds of Frequently-Doing" and "Four kinds of Stability" (namely frequentyl observing, frequently contacting, frequently analyzing and frequently adjusting; stable steam pressure, stable steam temperature, stable  water level and stable combustion ), and make the following adjustments. 

1. Ensure the boiler capacity in rated range, so that the boiler evaporation capacity can meet the needs of the unit load and the user. 

2. Keep the normal steam pressure and stable steam temperature. 

3. Keep the water level within the normal range for evenly water supply. 

4. Keep qualified steam quality. 

5. Keep the combustion and operation stable in order to strive to improve the combustion efficiency and thermal efficiency and to guarantee the economic operation of boiler. 

6. Closely watch the operation of the equipment, timely find and eliminate the equipment error in order to ensure the safe operation of the boiler.
