Unit Operation InstructionDDOP Probe3.2 GENERAL INFORMATION DDOP PROBEThe Double-Dry-nOn-cOoled-Probe (DDOP) is made of stainless steel, enabling it towithstand temperatures of up to 400°C.The DDOP probe is special designed for use after the pre-heater in cement plants. Theprobe is normally installed in the down comer pipe coming from the top of the pre-heater.The probe is a double probe thus it can be used for continuous measuring.A stainless steel filter is mounted in the probe, inside the process, the purpose of the filteris to avoid dust particles to be transported into the sample lines.Drawing no: 53895-DDOP-450-20 Page 7 of 14
Unit Operation InstructionDDOP Probe4 INSTALLATION OF PROBESee layout drawing “System View”4.1 BEFORE INSTALLATION4.1.1 TRANSPORTAll transport must be carried out according to local regulations. Transport may be doneeither with equipment in transport box or unpacked. When equipment is still in a box, itmay be moved by standard fork lift.When unpacked, the Probe is easily handled manually.It is highly recommended to unpack equipment as close as possible to installation point toprotect against damage during storage and transport.4.1.2 UNPACKINGBefore installation equipment must be unpacked, the wood box must be opened with acrowbar, or e.g. a circular saw (buzz saw) may be used to open the seaworthy box. The sawmust be carefully adjusted to a cutting dept of max. 2 mm though wood panels to avoiddamage of equipment.4.2 INSTALLING THE PROBEThe probe is bolted to the supplied flange, se layout drawings “DDOP: Probe”, “DDOP:System view”1. The measuring point must be located in a place where the gas is homogenous andrepresentative for the process.2. As rule of thumb there must not be any obstacles 5 x channel diameter before and 2 xchannel diameter after probe location.3. The probe must be positioned thus the filters are “protected” against the gas flow. Thisis to avoid directly downstroke of dust on the filter.4.3 FLANGE CONNECTION TO PROCESSThe flange is welded to the process4.4 CONNECTION OF HOSESAll hoses must be protected against environment and damage. Hoses must be secured toe.g cable ladders.4.4.1 CLEANING AIR HOSESThe probe is connected to the Probe Cleaning Panel using the hoses supplied. Position thehoses thus bends are avoided. Take care to leave space to withdraw the probe from theprocess without disconnecting any hose.Connect the cleaning air hoses according to the following tableFrom ProbeTo PCP10 mm Swagelok fitting on Line 1 10 mm bulkhead labelled “BB1”10 mm Swagelok fitting on Line 2 10 mm bulkhead labelled “BB2”4.4.2 HEATED SAMPLE LINESThe probe is connected to the GMU using the supplied heated sample lines E1 and E2. Inorder to avoid pressure drops and condensate traps the hose must be installed thus bendsDrawing no: 53895-DDOP-450-20 Page 8 of 14
