Abstract
Under present circumstances on the urgent relation of demand and supply of petroleum, it is significant that other form of the use offuel for the combustion installations such as furnaces and boilersis disscused for the purpose of energy saving, countermeasures of air pollution and so on
We have noticed the mixing firingsystem with heavy fuel oil “C grade” and liquefied butane whic is expected to improve atmization characteristics and to decrease th power for transportation of fuel.
The viscosity of mixed fuel ha been investigated to take the basic data with respect to the mixing firing burner.
The followings have been obtained.
(1) Suitable heating for heavy fuel oil “C grade” and intense agitation are effective for the mixing process.
(2) At the mixing ratio of 3, (the ratio of the weight of heavy fuel oil “C grade” to the weight of liquefied butane) dynamic viscosity of about 20 [cst] which is required for good atmization have been obtained under room temperature.
(3) By the measurement using capillary tube, following experimental equation of f he relation between dynamic viscosity and temperature has been obtained within the accuracy of ±30%.
