It is not productive to transform them to the boilers with solid fuel oily by mounting grills inside of such kinds of boilers; yet solid fuel oil may be burnt by mounting mechanically loaded coal stokers or front oven instead of boilers.
  • Cylindrical reverse pressed (reverse flowing) radiation boilers are the boilers with small capacity which are completely designed for the purposes of burning liquid and gaseous fuel oil and mostly used in apartment typed home heating. Since radiation-weighted heat transfer is provided with reverse flowing in small combustor in such kinds of boilers, the possibility to mount grills and burn solid fuel oil is limited.
