The Author discusses the design of Incymar incinerators for the disposal of shipboard waste, since dumping overboard is no longer permitted in many areas. It is considered that proper design can save as much as 60% of the fuel cost involved i.e. 20 to 40% of the initial cost per annum. The best type of combustion chamber consists of a thin refractory wall to take a relatively low temperature of 950 to 1,000 degree C, and a continuous cyclic operation at constant temperature must be maintained for as long as possible. The incinerator must be small but compatible with the amount of waste expected from the ship. The chamber, however, is relatively large owing to the thin refractory walls. As the burner will be arranged tangentially, the solid particles contained in the combustion gases cannot pass the central exhaust throat of the burnt gases situated at the centre of the chamber ceiling until their specific gravity equals that of the carrying gases, i.e. when they are completely burnt. This arrangement ensures complete combustion of solid particles in the incinerator chamber, without an extra cyclone chamber. The necessary safety characteristics for an incinerator are listed in detail and it is concluded that the Incymar incinerator fulfils all requirements. By modulating fuel supply and using a low calorific inertia, approximately 8 to 10 kg/h of fuel can be saved over the total period of operation. If heavy fuel oil is used the saving is even greater and could be in the region of 10,000 English Pound p.a. Order from BSRA as No. 52,745.
