A Bale-Fired District Heating System

A purpose built heating plant providing up to 10MW. Fueled by the Big-Bale System, an advanced automatic straw-fired system.

Havndal Heating Plant, Denmark

Fuel Storage

The system is supplied with fuel by means of an automatically controlled crane or conveyor,
which can be delivered in one or to storeys.

1 or 2 storie conveyors available

Boiler Room

The pre-combustion chamber and boiler are constructed as one unit. Flame and gas are drawn into the boilers main combustion chamber before passing through primary and secondary convectors. In plants dependent upon optimized fuel utilization, an economizer with integrated by-pass regulator is built into the boiler. The boiler and firebox are equipped for automatic ash removal through a port beneath the boiler. A mechanical conveyor transports wet or dry ash to a container.
Automation

The combined main-, monitor- and control panel is built with the most up to date PLC technology to ensure maximum reliability, ease of operation and maximum fuel utilization.
