The utility model discloses a gas-fired boiler flue gas waste heat device for a greenhouse, which comprises a boiler assembly and the greenhouse, the output end of the boiler is communicated with a first flue gas conveying pipeline, the output end of the first flue gas conveying pipeline is communicated with a first chimney, and the surface of the boiler is communicated with a second flue gas conveying pipeline. By arranging the boiler, the first smoke conveying pipeline, the first chimney, the first smoke control valve, the third smoke conveying pipeline, the second chimney, the greenhouse, the second smoke conveying pipeline, the heat conveying pipe and the second smoke control valve, the problems that an existing gas-fired boiler does not have the function of recycling exhaust smoke heat, the exhaust smoke temperature of the gas-fired boiler is usually high, the exhaust smoke temperature is 90-130 DEG C, and the energy consumption of the gas-fired boiler is low are solved. The problems that the high exhaus
