The present invention provides a system using low-temperature waste heat of gas of a generator unit to generate power, comprising: a first steam power generation system, a condensate water pipe, and a low-pressure heater and a condenser that are provided on the condensate water pipe. The first steam power generation system comprises a low-pressure cylinder, the low-pressure heater being connected to the low-pressure cylinder; and further comprises a device for recycling waste heat of gas and a second steam power generation system. The device for recycling waste heat of gas comprises a heat absorption section and a heat dissipation section, the heat absorption section is provided inside a boiler flue, and the heat dissipation section is arranged on a condensate water tributary that is in parallel with and is a branch of the condensate water pipe. The second steam power generation system comprises a second steam turbine and a second power generator that are connected, the second steam turbine is connected to the low-pressure cylinder by an extraction steam pipe, and the low-pressure cylinder and the second steam turbine are both connected to the condenser by an exhaust steam pipe. The present invention can further securely recycle the low-temperature waste heat of the gas, and use the recycled waste heat in a gradient manner to generate power once again, thereby solving the problem that accurate metering cannot be performed in the traditional power generation by recycling the waste heat, and further solving the problem that the low-temperature waste heat in a large power plant cannot be used efficiently, so that the power plant achieves the objective of energy conservation and environment protection. |
