The biggest limit of energy production of steam engines is the Carnot cycle ƞ=(T maxT min)/T max.. The efficiency even of the most modern coal power plants is ~ 30%.It means that ~70% of the produced energy gets out to the air when burning coal, and that means the same amount of the unnecessary CO 2 emission as well. The efficiency of locomotives is even worse.

a powder is wasteful of grinding mill power. On the other hand, too coarse a powder does not burn completely in the combustion chamber and results in higher unburnt losses. The pulverised coal is blown with part of the combustion air into the boiler plant through a series of burner nozzles. Secondary and tertiary air may also be added.
