The invention discloses a boiler and particularly discloses a gas-and-solid-fired environment-friendly industrial boiler comprising a vertical boiler body. The boiler body is in a membrane wall structure. The inside of the boiler body is n-shaped. The boiler body is provided with a gas burner and a solid burner. The gas burner is located above the solid burner. A hearth forms an uptake flue which is communicated with a horizontal flue at the top of the boiler body. A convection tube bundle is disposed in the horizontal flue. A down-take flue is arranged at the rear of the boiler body and is communicated with the horizontal flue. An economizer and an air preheater are sequentially disposed on the down-take flue. The boiler body is provided with the gas burner and the solid burner both communicated with the hearth, so that boiler pollutant emission under low concentration is achieved by burning solid fuels such as coal and biomass and gases such as natural gas and liquefied gas, and the situations of severe pollution emission and difficulty in control are changed for the traditional industrial boiler.
