 WIRAJASA Waste Oil Burner is the first of
its kind that applies superheated water or
subcritical steam to boost combustion or
oxidation of heavy oil.
 Key principle of this innovative device is
basically founded on two essential points:
preheating of waste oil and self-generated
subcritical steam.
 One similarity with other waste oil burners
developed in the USA and Europe is
preheating of waste oil.
 Other features that distinguish WIRAJASA
Waste Oil Burner from other devices
include:
Water is needed as the source of
subcritical steam.
Electric power requirement is low (only
8.6 kW).
 Air compression is required only at
the start of operation.

4. PROVEN TECHNOLOGY

7. THE COMBUSTION PROCESS
4/30/2013WIRAJASA Waste Oil Burner
7
Phase 1: Preheating of water to achieve standard temperature of 180 º C.
Water turns into a dry steam or sub-critical water and accumulate pressure
that is stabilized at 3 bars.
Waste oil absorbs heat from the heating water steam and reach a
temperature of between 90 and 100º C.
Phase 2: Injection or spray of heated, pressurized steam and mix it with
heated waste oil mist through an injecting nozzle and shoot the mix into the
combustion chamber.
The mix of steam particles and heated oil mist will cause oxidation that is
also known as combustion or burning and the temperature can reach as
high as 400º C.

8. THE FIRST & SECOND GENERATION
