Well Designed Heat Exchangers
- BINDER fire tube heat exchangers are highly efficient and are made to match your heating needs.
Manual maintenance is minimised through a fully automatic high-speed cleaning system*.
Sturdy tubing with 4.5 mm walls and optimum welding guar- antees a long lifespan.
- Fly ash and bottom ash are automatically conveyed into a detached ash container, using screw augers* or drag con- veyors*, or
- Ash is collected in integrated containers. Depending on the fuel ash content, these containers can be kept for weeks or months before further disposal.
Fully Automatic Tube Cleaning System*
This feature provides high-speed de-ashing of the heat ex- changer’s fire tubes in frequent and preset intervals without interfering with normal operation:
- prevents the formation of deposits, thus maintaining a constant and efficient heat transfer,
- reduces the de-ashing maintenance to 1-2 basic procedures per year,
- protects against boiler corrosion.
Capacity Control (Standard)
- Air supply and fuel inputs are coordinated to attain the ac- tual heat demand using PLC control and Lambda O2 regula- tion.
- When heat demand drops, the unit is operated in part-load mode or is shut down.
Capacity and Combustion Control
(CVP Control Package*)
Features a fully modulating computer control with 3 interlink- ing loops that permanently assess the actual requirement of heat, adjust the fuel feed accordingly, and match it with the continuously variable air supply.
- Reacts dynamically to changes in the combustion process through the Lambda O2 control which immediately adjusts the secondary air supply.
Variable air volumes are automatically compensated by the integrated negative pressure control.
Speed-controlled fans minimise electric power consump- tion.
Renders an optimal efficiency over the entire output range of 25% to 100%.
Accumulator Tank Management*
The use of hot-water accumulator tank systems works well with BINDER biomass boilers:
- Daily peak demands during full load periods are met through the accumulator tank.
- Heat demands during part-load periods are met through the boiler using modulating capacity control.
- Should the heat demand decreases further, the accumulator tank – now serving as the sole heat source – is loaded and then the boiler will be shut down.
- Repeated starts and shut-downs are substantially reduced, which increases the boiler’s lifetime and minimises air pol- lution as well.
