1.3 Incinerator: operation
The Incinerator is designed with a primary combustion chamber for burning sludge oil or solid waste, and a secondary combustion chamber for burning out uncombusted exhaust gases. The primary combustion chamber is equipped with a primary burner. Fuel is supplied to this burner for initial ignition. After this, sludge oil is supplied to the main burner until it ignites.
· The primary burner is switched off either automatically or manually. Atomised air is provided to the sludge burner for efficient combustion.
· A pressure regulating valve is provided on the sludge return line to adjust the quantity of sludge entering the conversion space.
· The heat from the primary burner will dry out and start burning the solid waste and ignite the sludge oil.
· The very large transmission area in the primary combustion chamber optimises the drying and burning of the solid waste.
· In the secondary combustion chamber, the gases from the primary combustion chamber will burn out.
·
A wall made of ceramic
heavy duty refractory lining separates the primary and the secondary combustion
chamber.
· In the case of solid garbage or waste, the waste is fed into the incinerator through the feeding door.
Note that the primary burner cannot be ignited. If this door is open, the rest of the combustion process is the same.
