SYNOPSIS: -Recently, various solid fuels combustion experiment have been carried out on the commercial scale experimental combustion equipment which was developed by auth-or's company for porpose of useful application of low grade fuels in our country.
Hokusyo coal and another few fuels was choosed for sample fuels of new developed fluidized combustion method.
In chemical industrial process, fluidization is very widely developed technics, and author explored the developement of new combustion mechanisms by aerodynamical and thermod-ynamical principles of fluidized reactions.
First commercial prototype large steam generator with fluidized combustion chamber is under successful operations and we hope this mechanism will serve as a tool to useful application of low grade coal in future.
