The new boiler line ATTACK DPX is equipped with the more efficient tubular exchanger flue gas – water. Special movable turbulators installed inside the exchanger serve to brake and to make the turbulent flow of the flue gas through the exchanger. Thereby it comes to higher heat transfer through the steel exchanger wall into the heating water.Turbulators also enable easy exchanger cleaning. The clean exchanger reaches the most effective operation parameters – the high efficiency.
From technical view it is a boiler line with high efficiency, low flue gas temperature and more effective combustion process. Achieved efficiency of the ATTACK DPX boiler is 90 %. By installation of more efficient boiler of the ATTACK DPX line it comes to significant decrease of the operating costs,projected into the fuel savings, in comparison with less efficient boilers that combust same fuel. From the social-wide view, it is an enviroment-friendly source, combusting wooden biomass, which is a kind of CO2-neutral fuel.
Considering the harmful emissions, the average concentration of CO value in the flue gas, is during operation of the LAMBDA version under the level of 200 mg/m3 related to 10 % of O2.
Under the valid European norm EN303-5, classifying the solid fuel boilers by efficiency and emissions to individual classes, the ATTACK DPX boiler (version LAMBDA) reaches 25 times lower concentration of harmful CO emisions in the flue gas in comparison with the allowed level of this norm!
ATTACK DPX LAMBDA
The wood gasifying boiler ATTACK DPX 45 Lambda disposes with the most advanced technology of the combustion process control to achieve the excellent values of emissions and efficiency. Controller can individually regulate amount of the primary and the secondary air, adequately to data about oxygene content from Lambda probe, boiler temperature and flue gas temperature. All the operation parameters are displayed on the well-readable multiline LCD display. The parameters can be change via buttons placed on the control panel of the boiler. Eventual error or warning messages are signalized by flickering LED diodes.
After the fuel burn-out is the boiler automatically stopped according to the flue gas temperature or the oxygene content
in the flue gas. All modifications of the ATTACK DPX boilers can be equipped with an additional regulator which ensures control of the accumulation tank, solar panels or other sources of heat energy in different designs of the heating systems, according to the customer´s demands.
