Solid Fuel Internal Combustion Engine

Click For Summary
SUMMARY

The discussion centers on the feasibility of building an internal combustion engine that operates on solid fuel, specifically referencing historical examples such as a British train from the 1930s that utilized coal dust. Participants highlight the necessity of heating solid fuel to produce vapor for combustion, akin to coal gas production. The conversation also notes the potential for high emissions due to the combustion of heavy compounds found in solid fuels like coal and flour. This innovative concept draws on past engineering efforts and raises questions about modern applications and environmental impacts.

PREREQUISITES
  • Understanding of internal combustion engine mechanics
  • Knowledge of thermodynamics related to heat transfer and combustion
  • Familiarity with solid fuel properties and emissions
  • Experience with historical engineering practices in fuel technology
NEXT STEPS
  • Research the design and operation of solid fuel internal combustion engines
  • Explore modern alternatives to solid fuel combustion, such as biomass gasification
  • Investigate emissions control technologies for heavy compound combustion
  • Study the historical context and engineering principles of the 1930s British coal dust train
USEFUL FOR

Engineers, automotive designers, environmental scientists, and anyone interested in alternative fuel technologies and historical engineering innovations.

Has anyone ever built an internal combustion engine which runs on solid fuel? A system would have to use waste heat or a mechanical friction device or whatever to heat the fuel and produce vapor which would be burnt in the cylinder (similar to the way coal gas was produced). Of course the vapor would be extremely dirty when burned because of all the heavy compounds involved. In the 1930's, a train was developed in Britain which ran on coal dust.

My father told me that when he was at UMIST there was an engine that ran on any flammable dust coal, flour etc.
