The utility model relates to a vertical three-pass fuel, gas and biomass-fired boiler, and belongs to the field of boilers. A combustor is vertical to the axis of a casing, and a refractory reflecting wall is opposite to an outlet of the combustor and is fixedly arranged at the inner wall of a boiler container; a second-pass thread smoke pipe is connected between a pipe plate of the boiler container and a lower pipe plate of the casing or between the pipe plate of the boiler container and an upper pipe plate of the casing, a third-pass thread smoke pipe is connected between the upper pipe plate and the lower pipe plate of the casing, and a smoke tube is communicated with an upper smoke chamber or a lower smoke chamber. The vertical three-pass fuel, gas and biomass-fired boiler has the advantages that the structure is novel, the cost is low, and the occupied area is small; the combustion and heat transfer are more sufficient, and the smoke exhaust is more environment-friendly; the heat efficiency is high, the energy consumption is low, the reliability and stability are high, and the environment-friendly property is good; the application range is wide, and the practicality is high.
