ABSTRACT
In this article the authors report that there is no efficiency advantage for operating a test boiler at a high (10-1) turndown ratio in comparison to a low (4-1) turndown ratio. However they also opine that the total energy capacity of a boiler, whether achieved by increased steam or water storage, is sufficient to allow the shorter cycle time associated with a lower turndown ratio. Ways to reduce Nitrogen Oxide (NOx) emission in gas combustion, are discussed.

    Using low price heavy fuel oil (HFO) in high-speed diesel engines is a practical way to reduce running costs. However, most high-speed diesel engines' fuel systems and combustion systems cannot adapt to HFO. This causes the problem of deterioration of combustion performance. In order to solve...
