The utility model discloses an energy-saving burner for a gas-fired boiler, which comprises a
gas mixing component, and the
gas mixing component comprises a mixing pipeline, a fan, a
shunting branch pipe, a gas jet orifice, an annular gas
pipe, a gas inlet
branch pipe, a gas inlet main pipe, a spiral mixing pipe, a
burning head and a gas flow regulating valve. According to the utility model, the gas flow regulating valve and the air flow regulating valve are used for accurately controlling the gas inlet amount and the air inlet amount, and the proportion of the gas inlet amount and the air inlet amount can be regulated in real time according to boiler load, so that
energy consumption requirements under different working conditions are met, sufficient
combustion is ensured, the energy
utilization rate is improved, and energy waste is reduced; the gas injection opening is obliquely formed and is consistent with the air flowing direction, gas and air are preliminarily mixed in the flowing process, the gas and the air are mixed more evenly through the spiral mixing channel of the spiral mixing pipe, the contact area is increased, the
retention time is prolonged, conditions are created for efficient
combustion, and compared with a traditional
combustor, the
combustion efficiency is greatly improved, and the combustion efficiency is greatly improved. And the emission of pollutants is reduced.
