Municipal waste disposal, pollution optimization and
generation of green energy like electricity are the serious
issue of the developed and developing cities throughout the
world. With the growing population and digitalized lifestyle,
the municipal waste is also increasing. Municipal waste now
a day's includes paper, plastics, wrapping boxes etc. These
contain high calorific value which is almost half of the high
grade coal. Proper thermal treatment of these municipal
wastes can be utilized to energy generation along with
industrial and hospital steam supply. In this work we are
proposing a thermo-geometric analysis to design a riserdowncomer circuit under a stipulated steam generation rate
for a typical municipal waste fired boiler (MWFB). The
boiler is running on the thermosyphon principle and powered
by the municipal waste firing. A numerical model is
developed focusing on the two phase thermosyphon which
will solve the thermo-geometric design issue associated with
the municipal waste fired boiler (MWFB). Appropriate heat
transfer and pressure drop correlations have been employed
in the model. The critical heat flux condition and tube
burnout issue, complex two phase flow are considered and
handled by homogeneous averaging concept in this work.
