Examples

    Steam, Its Generation and Use

  • To repeat, it must be emphatically borne in mind that the question of smokelessness is largely one of degree, and dependent to an extent much greater than is ordinarily appreciated upon the handling of the fuel and the furnaces by the operators, be these furnaces hand fired or automatically fired.

    Steam, Its Generation and Use

  • It is safe to say, however, that no plant will operate smokelessly under any and all conditions of service, nor is there a plant in which the degree of smokelessness does not depend largely upon the intelligence of the operating force.

    Steam, Its Generation and Use

    Steam, Its Generation and Use

  • The principle upon which these stokers base their claims for efficiency and smokelessness is that the green fuel is fed under the coked and burning coal, the volatile gases from this fresh fuel being heated and ignited in their passage through the hottest portion of the fire on the top.

    Steam, Its Generation and Use

  • Smoke -- The question of smoke and smokelessness in burning fuels has recently become a very important factor of the problem of combustion.

    Steam, Its Generation and Use

    Steam, Its Generation and Use

  • This smokelessness can be understood from the fact that the products of combustion are nearly all non-condensible gases, and contain no solid products of combustion which would cause smoke.
