FUEL SUPPLYHYDRAULIC CIRCUITVarious hydraulic circuit are available, depending on fuel outputasset according to local norms of steam generators.The burners are fitted with two valves (a safety valve andan operation valve) and an oil filter along the oil line fromthe pump to the nozzle.A pressure regulator on the return circuit from the nozzleallows to vary the quantity of fuel burnt.A double safety valve on the return circuit avoids oil leakagefrom the nozzle when the burner is in stand-by and prepurgephase.The models are fitted with a maximum pressure switch onthe oil return circuit.Example of the hydraulic circuit on PRESS 200 P/GEN 267 > 100 kg/hPFOVS VFVR1 VRPOmaxM SMROMRUPFOVSVFUMRSMROPO maxVRVR1Pump with filter and pressureregulator on the output circuitOil filterSafety valve on the output circuitWorking valve on the output circuitNozzlePressure gauge on the return circuitServomotorPressure regulator on the returncircuitMax.

SELECTING THE FUEL SUPPLY LINESThe fuel feed must be completed with the safety devices required by the local norms.The table shows the choice of piping diameter for the various burners, depending on the differencein height between the burner and the tank and their distance.ModelDiameter piping+H, -H (m)+2,0+1,5+1,0+0,50-0,5-1,0-1,5-2,0-3,0MAXIMUM EQUIVALENT LENGTH FOR THE PIPING L[m]P 140 P/GP 200 P/GP 300 P/GØ14mmL max (m)5045403530252015105Ø16mmL max (m)70656050454035302515Ø16mmL max (m)4035302520181513105Ø18mmL max (m)60555045403530252010Ø1/2”L max (m)25232018151210853Ø 3/4”L max (m)85807065605045353015P 450 P/GØ 3/4” Ø1”L max (m) L max (m)55 13050 12045 11040 10035903080257020601545102567109 5 VP+H10 cm847 5 3921H Difference in height pump-foot valveØ Internal pipe diameterP Max. height 10 mV Height 4 m1 Burner2 Burner pump3 Filter4 Manual shut off valve5 Suction pipework6 Bottom valve7 Remote controlled rapid manualshut off valve(compulsory in Italy)8 Type approved shut off solenoid valve(compulsory in Italy)9 Return pipework10 Check valve-H6noteWith ring distribution oil systems, the feasible drawings and dimensioning are the responsibilityof specialised engineering studios, who must check compatibility with the requirements andfeatures of each single installation.

VENTILATIONThe ventilation circuit is provided with a forward blades centrifugalfan, which guarantees high pressurelevels at the required air deliveries andpermits installation flexibility.In spite of the remarkable output powerand of the very high pressure performances, structuresof PRESS models are extremely compact.The use of sound proofing boxes help in reducing thenoise level.A variable profile cam connects fuel and air setting,ensuring fuel efficiency in all firing rates.Example of servomotor forair/light oil settingCOMBUSTION HEADTwo different lenghts of the combustion head can be chosen forthe various models of the PRESS P/Gseries of burners.The choice depends on the thickness ofthe front panel and the type of the boiler.Depending on the type of heat generator, it is necessaryto check the correct head penetration into the combustionchamber.These burners are equipped with a variable geometrycombustion head. The chance to control air speed incombustion head is essential to gain the full advantageof a modulating burner. This function allows optimumcombustion performance throught the working field,ensuring peak combustion efficiency thus saving on fuelconsumption.The following diagram shows the flame dimensions inrelation to the burner output. The lenght and diametershown in the diagram below should be employedfor a preliminary check: it is required a more careful investigation if combustionchamber dimensions are much different from the above reported values.Flame dimensionsExample of a PRESS P/G burnercombustion head74Flame lenght (m)65432100 1 2 3L maxL minD maxD min3,532,521,510,504 5 6 7 8 9 10Burner output (MW)Flame diameter (m)DLExample:Burner thermal output = 3500 kW;L flame (m) = 3,5 m (medium value);D flame (m) = 1 m (medium value)
