Operating Result

Gas pressure plays an important role in the economic efficiency and stability of the operation of gas-fired boiler. However, because of the inherent characteristic of gas booster which is introduced to regulate the pressure of gas, there is surge happened in gas booster, resulting in deviation of gas pressure from set value, even damage to device. To settle the problem of surge, an anti-surge control is designed based on the characteristic curves of gas booster. And the control strategy is applied in a thermal power plant with gas-fired boiler. The practical operating result shows the effect of the proposed method.
