Mesta Memories #11 – Steam Blowing Engines

plantproductofme00mest_0053The Mesta Machine Company also made steam blowing engines that were less expensive and of generally a lower output than the Mesta gas blowing engines. They were still very formidable devices as you can see from the image above.

I am somewhat puzzled by the designations that Mesta gave to their blowing engines. For example, in the image above, the engines are described as [44″ and 84″ x 60″] engines. The 84″ x 60″ refers to the bore and stroke of the piston, but I don’t know what the 44″ dimension refers to. Even more puzzling is the designation of the engines on page 45 described as [Three 34″ and 66″ and 84″ and 84″ x 48″] engines. Except for the bore and stroke, I have no idea what the other dimensions refer to. If I ever figure it out, I’ll let you know.

Mesta Memories #10 – Gas Blowing Engines

plantproductofme00mest_0044I’ve written about blowing engines before in Big, Complicated Machines #7, but the gas blowing engines produced by Mesta were quite different. The Mesta engines ran on the waste gasses produced by the blast furnaces that the blowing engines serviced, with little or no extra fuel required. I’m sure that there are some caveats to that statement however. The horizontal design of the engines made construction of the blowing houses much simpler and cheaper. In addition, each Mesta blowing engine also had a generator that produced electricity for the steel mill. They were a fairly elegant piece of engineering.
