MORE POWER FOR GAS ENGINES

Users of' gas engines on a large scale , ,aro commencing -to realise that the heat ’ carried away by the exhaust from gas engines amounts to about one-third of the ’total heat generated, and’ that the exhaust gases, being ata temperature of about 1000 deg. F., are capable of raising a large, amount of steam, provided .that a boiler suitable for the. purpose is .installed.' According to ; the Railway and Fnginoeijing Review* such boilers are now., being pyioed as near to *the'engine cylin.der as * possible, and they consequently form a por.feet silence*. ; When the. gases have passed through the boiler they escape into the atmo&phero bya pipe which js free from the usual nuisapioe of heat .and noise. Inasmuch as gas power has not so fay been favorably considered in many plants because of the -need of the oxnaust steam from steam-engines for special purposes there is now a chance for the adoption of the exhaust gas boiler to raise steam fer heat or other purposes, while the motive power is gas, and thus a double measure of economy, and usefulness is attained. Tn one factory in England these boilers are generating steam from the-heat of the gns engine, exhaust £oses equivalent to. the steam generated by 70 toisi of coal per week; •
