Fundamental study on incineration of woody waste including seawater using the two-stage combustion method

Autor: Fumiaki ABE, Masaya NAKAHARA, Kenichi TOKUNAGA

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 83, Iss 846, Pp 16-00351-16-00351 (2017)

The objective of this study is to establish a method of direct combustion that allows safe and effective incineration of difficult-to-process woody waste as well as its utilization as fuel. A tremendous amount of debris including woody waste was wash

Experimental Study on Local Flame Properties of Hydrogen Added Hydrocarbon Premixed Turbulent Flames

Autor: Masaya NAKAHARA, Takamori SHIRASUNA, Jun HASHIMOTO

Publikováno v: Journal of Thermal Science and Technology, Vol 4, Iss 1, Pp 190-201 (2009)

This experimental study is performed to investigate directly the local flame properties of turbulent propagating flames at the same weak turbulence condition (u'/SL0=1.4), in order to clarify basically the influence of the addition of hydrogen to lea
