ŠUKOPLAM VENT 25 - 95 kW
Characteristic dimensions table
Boilers type Šukoplam VENT with power range 25-95kW are in essence modified boilers of Šukoplam LUX 25-80kW family.This modification is done in adapting the standard boiler for combustion of chunk solid fuel and grain biomass (pellet, fruit stones, coals with maximum granulation of 8mm).Combustion of grain biomass is done completly automaticly.
Boiler is constructed as „three drafted“ with two water cooled chambers and flue pipes which means that products of combustion pass water area in three occasions maximizing the heat exchange.Boiler firebox is divided into two sections, front section for combustion of chunk solid fuel and back section with fluidisation chamber for combustion of grain biomass.Chunk solid fuel loading is done through middle boiler door while grain biomass loading is done with screw conveyor at the side of the boiler. Storage of grain biomass is done i fuel storage tank underneath, via the rotational dosage mechanism, screw conveyor takes the fuel and brings it to the fluidisation chamber.Volume of fuel storage tank is done so that it meet the daily need of the boiler.Ignition of grain biomass is completly automatic via the electric igniter.For combustion of grain biomass primary air fans are used and are chosen in a way to deliver enough fresh air for combustion and fuel fluidisation. Primary combustion air is divided in the fluidisation chamber into primary and secondary air, and also part of the primary air is delivered to the screw conveyor to prevent the return of the flame from the combustion chamber to the fuel storage tank.Air for combustion of chunk solid fuel enters the boiler through the flap on the bottom boiler door, and it volume is regulated with draft regulator.In this case only the exhaust fumes fan work while primary air fans do not work.By installing the sediment chamber and exhaust fumes fan boiler is kept in underpressure so there is no risk of the return flame towards the fuel storage tank and to the middle boiler door, and by installing the turbulators into flue pipes boiler efficiency can be raised 7-10%.Automatic controller, based on the input parameters (water temperature, flue gas temperature, room temperature), gives command to output devices (fans, igniter, screw conveyor) and maintains all the desired parameters for smooth boiler work.Boiler body is well insulated with mineral wool and boiler sheeting is protected with painting or powder coating processes.
Boiler is meant for production of hot water in operating mode 110/90ºC and 90/70ºC with maximum allowed work pressure of 2,5bar.
Protection of boiler from increased pressure is done by installing the safety valve on the appropriate place on the boiler, while protection of the boiler from increased temperatures is done by installing the safety heat exchanger which,if the need arises, cools down the boiler.
