Design and Study State Thermal Analysis of Super Heater Coils

The document analyzes the thermal stresses on super heater coils in high pressure boilers. It studies the internal pressures and temperatures experienced by the coils' steel alloy materials during real operating conditions. Specifically, it models and compares STEEL ALLOY-213 TUBE-22 and STEEL ALLOY-213 TUBE-23 materials to determine which withstands continuous high temperatures better through reduced creep and is less prone to strain cracks or deformation. The analysis was conducted using ANSYS software on a model created in CATIA.

Design and study state thermal analysis of super heater

coils

Abstract:

The super heater can be treated as the heart of any boiler system,
super heater coil type panel is employed to convert saturated steam to super
heated steam. And therefore improves the thermodynamic efficiency of the
system this reduces plant operating costs and also helps to avoid thermal
shocks to the boiler metal And Sources that can lead to deterioration of steam
super heater coils of a high pressure boiler were studied by a stress analysis,
focused on internal pressure and temperature experienced by the material at real
operating conditions. Generally these coils are made by formation of thick wall
low alloy steel like STEEL ALLOY- 213 TUBE-22 material. The power
generating capacity of power boiler is 500 MW. This STEEL ALLOY- 213
TUBE-22 material has low creep strength and it cannot withstand continuous
high temperature to rectify the above problem, the usage of an alternate material
called STEEL ALLOY-213 TUBE-23 was attempted, STEEL ALLOY-213
TUBE-23 material is having better creep strength while compared with STEEL
ALLOY-213 TUBE- 22 material. In this paper structural thermal analysis and
which can be subjected to strain cracks, total deformation, heat flux, and
Thermo structural stresses of super heater coils. This analysis done with the
help of anasys software. Dimensional inspection, modelling is using the catia
software.

Keywords: super heater coils, STEEL ALLOY-213 TUBE-23, high
