The main components of the gas clean-up plant are as follows:
- Heat exchanger with dry cooler
- Spark arrestor
- Bag filter
- ID fan
- Mercury & Dioxin Filter
The heat exchanger is a double pass water jacket boiler designed to cool the exhaust gasses from the cremator to 150°C. The closed loop design includes a dry cooler within the system. The heat exchanger supplied with an automatic cleaning system which lowers the maintenance interval to only twice a year.
The spark arrestor removes large particulate matter generally > 1 micron the flue gasses to protect the bag filter.
The flue gasses, already cooled to 140°C, enter the bad unit, which consists of a number of cartridge filters to remove substantially all of the remaining particulate matter. It should be noted that this particulate matter collected in the filter unit is produced entirely from the cremation process and completely free of additives of any kind and such it does not require special treatment for disposal.
