Abstract

The utility model discloses a heat recovery boiler for cooling biomass synthesis gas to generate electricity. The heat recovery boiler is composed of a boiler cylinder, a vertical membrane water wall, a bent flue and a tail vertical flue. The vertical membrane water wall, the bent flue and the tail vertical flue are integrally connected to form an n-shaped structure. A heated surface comprises an economizer, the membrane water wall, an evaporator, a low-temperature superheater and a high-temperature superheater. The economizer is communicated with the boiler cylinder through an outlet pipe to provide hot water for the boiler cylinder. A lower header of the membrane water wall is communicated with the bottom of the boiler cylinder through a down pipe, a lower header of the evaporator is communicated with the bottom of the boiler cylinder through a down pipe, an upper header of the membrane water wall is communicated with the boiler cylinder through a steam water outlet pipe, and an upper header of the evaporator is also communicated with the boiler cylinder through another steam water outlet pipe.
