同一ボイラによる各種ストーカ・バーナの性能比較

抄録

Two coal-stokers and three oil-burners (simple pressure-atomization type) have been tested in the same No.1 test boiler of our laboratory, and the detailed performance curves of those stokers and burners were obtained, concluding with the following considerations : (1) at the point of the best efficiency, the oil-burners were better than coat-stokers. (2) The working ranges of oil-burner were narrower than those of coal-stoker. (3) The excess air ratio of oil-burner at the best efficiency was smaller that of coal-stoker. (4) In the case of oil burning there were certain best density of smoke that gives best efficiency. The facts thus found are those commonly known already, but these results of our laboratory test give the exact and detailed deta and consideration for the comparison of the performance of oil-burner and coal-stoker, since the test was conducted with the same boiler under the same conditions.
