KWB Powerfire TDS 150

KWB – premium Austrian boiler technology

Founded in 1994, the KWB premium Austrian manufacturer specializes in automatic biomass heating systems. The Powerfire series is designed for heat supply to larger buildings and sites.

KWB Powerfire TDS 150 – automatic heating

adjustable output between 45–150 kW, wood chip and pellet operation, automated cleaning: a flexible solution for facilities with varying heat demands.

Key benefits

• Self-cleaning rotating grate: the movement of the grate continuously advances the burning fuel, forms a more uniform fuel bed, and helps remove burnt residues.
• Cyclone combustion chamber: the directed flow of flue gas promotes the burnout of combustible gases and the separation of fly ash.
• Broadband lambda control: by measuring the oxygen content of the flue gas, the control system adjusts the combustion air to the fuel and the instantaneous load.
• Automatic output control: the boiler adapts its operation to the heat demand, allowing it to be used at part load as well, not just at full output.
• Automatic heat exchanger cleaning: turbulators moving in the tubes regularly remove deposits and improve the transfer of flue gas heat to the heating water.
• Multi-stage ash separation: finer ash particles are also separated from the flue gas changing direction multiple times in the heat exchanger.
• Automatic ash removal and ash compaction: the system transports and compacts the ash into a collector, reducing the frequency of manual ash removal and emptying. The control system also monitors the saturation of the ash collector.
• Backfire protection: a gastight fire protection shutter separates the fuel feeding system from the combustion chamber.
• Wood chips and pellets: designed for wood chips of quality Powerfire G30/G50 or P16B/P45A up to a maximum moisture content of 45%, as well as high-quality wood pellets.
• KWB Comfort control: in addition to boiler operation, the heat supply for heating circuits, the buffer storage tank, and domestic hot water can also be coordinated; the system is expandable with modules.
