Description
Technical Field
The utility model belongs to the technical field of the gas-steam combined cycle exhaust-heat boiler of energy power trade, concretely relates to combined cycle exhaust-heat boiler L shape flue gas channel system.
Background
The gas-steam combined cycle unit mostly participates in peak shaving of a power grid and operates under a partial load working condition, however, as the load of the gas turbine is reduced, the heat consumption rate is increased, and the economy is reduced, so that the improvement of the variable working condition operation efficiency of the gas-steam combined cycle unit becomes an important research. The gas turbine unit with higher parameter level gas turbine exhaust has better variable working condition performance, the pressure, temperature and flow of flue gas entering a main flue of the waste heat boiler have larger adjustable ranges, and the structural arrangement of all parts of the heating surface of the waste heat boiler needs to be adjusted correspondingly.

In addition, the high parameter of the flue gas discharged into the waste heat boiler by the gas turbine of the existing combined cycle unit can reach 630 ℃/1.045MPa, the inlet pressure of the flue gas of the waste heat boiler is 3kPa higher than the atmospheric pressure, the flue gas is in a positive pressure running state, the risk of flue gas leakage exists, a laser or infrared imaging alarm system is required to be used, and the flue structures in horizontal and vertical structures lack a space for arranging optical instruments. Although some units adopt the induced draft fan for reducing the positive pressure of the flue gas, the induced draft fan is arranged at the tail of the chimney, the flue gas induced draft fan needs a large amount of electric energy, and the efficiency effect is extremely low.
On the other hand, from the viewpoint of optimizing the performance of the unit, the IGV air inlet guide vane adjustment is a variable working condition adjustment mode which is widely applied, namely the load of the gas turbine is reduced by gradually closing the IGV angle and reducing the inlet flow of the gas compressor, so that the gas temperature at the inlet of the turbine can be improved to improve the variable working condition efficiency. However, the unit cannot adjust the load by closing the IGV angle all the time, otherwise the gas flow is further reduced, and the final expansion ratio of the gas turbine is reduced, which may cause turbine exhaust over-temperature. Moreover, the gas temperature at the turbine inlet of the gas turbine can not be directly measured at present, which causes certain difficulty in controlling the exhaust temperature range of the gas turbine.
