To meet the demand for super-large coal storage facilities in new

expanded

and renovated thermal power plants

this article focuses on the structural design study of a 50 000 m3 coal storage silo for a thermal power plant.By researching and analyzing its process and structural layout schemes

a finite element analysis model was built

and three silos with different diameters were structurally selected

calculated for stress

and economically analyzed.This helped determine the stress patterns of the silo as a whole and its components under various load conditions such as self-weight

stored material

wind

earthquake

and temperature

as well as carry out structural reinforcement and component design.The results show that the 50 000 m3 coal silo with a diameter of 40 m has reasonable stress

the lowest engineering cost

optimal overall benefits

and engineering feasibility.
