Biomass Process Steam Plant Room Technology

Item 1
1 -P4PD H13, 3-pass high pressure steam boiler with a max continous capacity of 390 kgs steam/hr with a feed water temperature of
105°C and at a design pressure of 1,3 MPa.
The steam boiler is of all welded construction.
Measurement according to acc.to 600162
Valves and fittings
The valves are flanged except for small valves which are threaded. The boiler is equipped with the following items:
1 - main steam valve con 40
2 - spring loaded safety valves con 25
1 - feed valve (n.r.v.) con 25
1 - shut-off valve for ditto con 25
1 - perforated feed pipe con 25
1 - blow down valve con 25
1 - ventilating valve con 20
2 - water gauge with blow down valves and water level indicators (heavy type) con 20
1 - Test water valve incl. water testing cooler
1- Drain funnel with internal prepared drainpipes on boiler con 20
Lagging
The boiler is efficiently insulated with 100 mm highly insulating glasswool and the boiler except doors is enclosed with aluminium Stucco on
roundparts and protective shell of blue steel sheet on boilers ends.
Water cooled back flue chamber
Completely without staybolts constructed so that the cleaning of both the water and gasparts can easily be made. This construction
eliminates the conventional brickwork.The completely watercooled flue chamber reduces the radiation losses to a minimum which gives the
VEÅ UNIVEX boiler a very high efficiency.
Excentrical placed furnace
The eccentrical situated furnace gives a splendid circulation and makes it very easy to inspect and clean the water side.
Inspection doors
The boiler is supplied with soot doors for the smoke gas side and mudholes on the water side and a special inspection door with glass for
control of the combustion.
Burner front
Burner front is made for Janfire 300Kw pelletsburner and also ash connection beneath burner.
Manufacturing according to 97/23/EC (PED)
The boiler will be manufactured and CE-marked in accordance with the stipulations in 97/23/EC (PED)
Item 2
Selfchecking low low water control incl.feed water pump control
2 - low low water control ERK-S
1 - low water control including feed water pump control ER7
2 - electrode stands
Item 3
Timercontroller bottom blow down equipment
1 - bottom blow down control ERB
1 - electric bottom blow down valve DN25
