Novel 700 DEG C ultra-supercritical pi-type corner tangential combustion boiler structure

Abstract

The invention relates to a novel 700 DEG C ultra-supercritical pi-type corner tangential combustion boiler structure. The structure comprises a furnace arch arranged on a rear wall and an inverted triangular arch arranged on a front wall, the inverted triangular arch is arranged in an over fire air upper area of a boiler, and a hearth outlet is formed above the furnace arch. Compared with the prior art, the furnace arch of the rear wall is used for preventing flames in a furnace from directly entering a horizontal flue, the length of the horizontal flue is increased, and more heating surfaces can be arranged; the inverted triangular arch of the front wall enables flue gas distribution in the height direction of a hearth to tend to be uniform under the condition that the flue gas fullness degree in the hearth is guaranteed, and the inverted triangular arch of the front wall is concavely arranged to have a certain transverse depth, so that rotation residues caused by a tangential combustion mode can be weakened; and meanwhile, longitudinal scouring of flue gas to a platen superheater is reduced, flue gas disturbance on the upper part of the hearth is increased, convective heat exchange of the platen superheater is enhanced, and therefore the flue gas temperature and speed deviation at the outlet position of the hearth are effectively relieved.

AI Technical Summary

Benefits of technology

This patented technology helps improve the efficiency of waste incineration systems used for treating industrial wastes such as coal slag or metal scraps. It involves extending the retention period of the exhaust gases from the system into the furnaces while ensuring proper mixing between them before they are released through an opening called the flange on the roof. By adding this fused arc angles instead of rectangles, there will be longer flames without affecting their effectiveness. Additionally, the design allows for equal distribution of airflow over both vertical and horizontal sections of the kiln, resulting in improved control of pollution emissions during operation. Overall, these technical improvements help optimize waste treatment processes and enhances environmental impacts associated with energy production.

Problems solved by technology

This patented describes an improved method for producing super critical carbon dioxide (CO2) from fossil fuel combustion processes that uses low temperatures or near atmospheric conditions. These techniques have been developed around 1950 when it was discovered that certain types of chemical compounds were able to form stable solid solutions called permaqueroids during decompositioremediation procedures involving burning fossils. However, these methods require very specific material properties such as molar ratio between oxygen atom and nitrogen atoms, surface area, porosity, etc., making them difficult to optimize.
