Design Analysis of a Miniature Steam Boiler for Generation of Steam

Miniature Steam Boiler for Generation of Steam

Abstract

Current research into renewable energy sources, energy efficiency techniques, and cutting-edge technologies is intense among governments, corporations, and the scientific community in an effort to meet the world's energy needs while mitigating the impact of human activities on the environment. A design analysis of a small steam boiler for steam generation was done in this work. Along with the creation of a conceptual design, specifications and design considerations were produced. The permitted expansion stress range, minimum pipe wall thickness, cylindrical steam boiler characteristics, and minimum cylinder wall thickness were all established. The minimum thickness (t) of the cylindrical steam boiler was determined to be 2.0815 mm. Nonetheless, when  a factor of safety of 1.5 and a 0.9 mm allowance for corrosion is incorporated, the actual thickness of the cylindrical vessel employed becomes 4.02 mm. The minimum wall thickness of the pipe was 1.5 mm. In addition, a design temperature of 426 °C and an ambient temperature of 32 °C were chosen. It was calculated that the allowable expansion stress range was 166.1 MPa. When the steam spring relief valve was calibrated, the force at which pressure is released was measured and the result was 312.4 N.
