ŠUKOPLAM VPR 25 - 900 kW

Hot water solid fuel boilers type Šukoplam VPR 25-80kW are basicly the modification of boilers type Šukoplam R 25-80 kW and Šukoplam VPR 100-900kW.

This modification includes installing the special sediment chamber with exaust fumes fan (for boilers -200kW) and mechanical particle separator (cyclone) with exhaust fumes fan (for boilers 100-900kW) instead of the normal boiler flue.In this way boiler works with „artificial draft“. Instalation of exhaust fumes fan makes better combustion in the boiler as well as keeping the required temperature within the fine borders.This fine temperature regulation is very important in numerous industrial processes, which make theese boilers an excellent choice for process industry.Also, because of the exhaust fumes fan, boiler can work without problems coupled with chimneys which by their characteristics (diameter and height) wouldn't give the desired draft for the standard boiler. In case of power suply disruption or exhaust fumes fan malfunction, sediment chamber (cyclone) is equipped with a by-pass flap which allows the boiler to go from artificial to normal (chimney) draft.

                Work of the exhaust fumes fan and practically maintaining the desired temperature within the fine limits is controlled by the boiler automatic controler. Installing the exhaust fumes fan also, because of the increased draft in the boiler, demands that turbulators must be installed into flue pipes. Turbulators are used to change the increased laminar flow of flue gases into turbulent flow and in that way increase the heat exchange between the water and flue gases.This as a result has higher efficiency of the boiler (7-10% higher) and savings in fuel in use.

                Boiler itself 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 maximasing the heat exchange.Boiler body is well insulated with mineral wool and boiler sheeting is protected with painting or powder coating processes.

                Boiler is ment for production of hot water in operating mode 110/90ºC and 90/70ºC with maximum allowed work pressure of 3bar.  

                Regulation of air flow needed for combustion of chunk solid fuel is done with draft regulator which moves  the flap on the bottom boiler door and by doing so increases or decreases the amount of air needed for the combustion as well as by changing the RPM of the exhaust fumes fan.

                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.
