Gas-fired boiler - Elettro Termica Sud S.p.A.

The detector 27 detects the pressure difference between these two positions to cut off the supply when such difference is zero --i.e. when there is zero flow through the exchanger 9. The gas supply of the burner 6 is by way of a gas supply path 28 communicating by way of a valve 29 with the mains supply by way of a combustion control box 31.

The approach is the difference between the economizer water outlet temperature and the Saturation temperature of the steam. A good approach point is between 15°F 30°F. This temperature will guarantee that no steaming will occur in the economizer section. It is not always possible to achieve an approach point in this zone.

But if the fuel is not in cascade the boiler master output tracks the fuel flow SP. If the boiler master is in manual or tracking its bias tracks the difference between it and the plant master output. If there is only one boiler the output of the plant master is the boiler master and no bias is needed.

Natural Gas Fired Boilers

Airflow and flue gas flow is slightly lower or about the same. Natural gas boilers operate at lower excess air (O2) and a different airflow requirement for stoichiometric combustion. Coal fired boilers normally operate with 3-3.5% O2 (about 20% excess air). Whereas natural gas boilers normally operate at 1-1.5% O2 (about 7% excess air).

Options for Improving the Efficiency of Heat Recovery ...

In a conventional boiler it is a well known fact that increasing the excess air decreases the boiler efficiency. In a HRSGthe excess air is decreased by addition of fuel which increases the efficiency. Also we have a lower exit gas temperature which also contributes to the efficiency improvement.
