All cremators of the above said crematoria is provided and installed by IFZW, a German company which specializes in construction, distribution and assembly of environmental incinerators since early 1930s.
Diagram below shows the cremation and the cleaning of waste gas process
The basic component of cremation system includes the Insertion Equipment, the Main Combustion Chamber, the Secondary Combustion Chamber, the Mineralization Chamber, the Rotary Valve System, and the Ashes Removal.
Cooling Chamber Rotary Plate
Flat Bag Filter
Flue Gas Exhaust Duct
Main Chamber Rotary Plate
Chemical Waste Barrel
Mineralization Chamber Rotary Plate
Flue Gas Duct
All cremators are "Free-fall" type.
The coffin  is placed in front of the cremator on the coffin conveyor , while the average temperatures of the main chamber  and the secondary chamber  attained 650°C and 850°C respectively 10 minutes before the coffin insertion, controller will open the furnace door  and the cremation process will then be started. The coffin will stay in the main chamber for not less than 55 minutes; controller will then open the furnace door again to inspect whether the primary cremation is satisfactory. According to controller judgment, ashes will then be rotated to the mineralization chamber  through the main chamber rotary plate  (so-called: #1 rotary plate). After next 30 minimum minutes of mineralization, ashes will then be rotated to the cooling chamber  for cooling down through the mineralization chamber rotary plate  (so-called: #2 rotary plate). Ashes after cooling will then be rotated to the ashes container  for collection and pulverization through the cooling chamber rotary plate  (so-called: #3 rotary plate).
