Abstract

The invention discloses a coal water slurry gasifying furnace with five nozzles. The furnace comprises a furnace body, wherein the top of the furnace body is provided with a top nozzle; the side wall of the furnace body is provided with four side nozzles; the material inlet nozzles of the side nozzles are lower than material outlet nozzles; an included angle formed by the axis of the side nozzles and a horizontal plane is large than 0 degree and less than 90 degrees; and the four side nozzles are arranged on the lower middle part of the furnace body at the same height. In the technical scheme of the invention, the material feeding mode that a single nozzle at the furnace top and multiple nozzles on the furnace side spray material simultaneously is adopted; and compared with the prior art, the furnace disclosed in the invention has a simple structure and can be used for industrial production.

Description

technical field [0001] The invention relates to a device capable of gasifying coal-water slurry. Background technique [0002] Coal water slurry gasification technology is a new technology involving the four major industries of coal, chemical industry, electric power and building materials. Western developed countries have been engaged in the research and development of clean coal technology since the 1970s. The US Department of Energy has started the Clean Coal Technology Program since the 1980s. In the 1980s, the world's first integrated gasification combined cycle (IGCC) - Cool Water (Cool Water) power station came out, using coal-water slurry gasification to produce gas as gas turbine fuel, and was internationally known as "the world's cleanest (coal) power station." . [0003] Coal-water slurry gasification is the second-generation coal gasification technology developed on the basis of heavy oil gasification. It belongs to the gasification process of pressurized entr...
