Hot state experiment device used for combustion organization optimization

The utility model relates to a hot state experiment device used for combustion organization optimization. In our country, a traditional hot state experiment device used for boiler combustion organization optimization research is small in capacity, and requirements for full-scale test research for boiler combustion cannot be met. The hot state experiment device comprises a W flame device (1), and is characterized in that one end of the W flame device (1) is connected with a water sealed slag hopper (2), and the other end of the W flame device (1) is connected with a four-corner-tangential cutting device (3), the four-corner-tangential cutting device (3) is connected with an full-combustion device (4), the full-combustion device (4) is connected with a horizontal flue (5), the horizontal flue (5) is connected with a secondary blast preheater (6), the secondary blast preheater (6) is connected with a primary blast preheater (7), the primary blast preheater (7) is connected with a coal economizer (8), and the coal economizer (8) is connected with an outlet flue (9). The hot state experiment device is used for hot state experiments of the combustion organization optimization.
