Made for (almost) every use
HDG is one of the first manufacturers to succeed in using the proven moving grate technology even in small combustion plants – the HDG stepping grate technology. The material travels through different temperature zones on the air-cooled and movable grate. In the process, it is dried, degassed and finally burnt. The constant movement of the grate elements reliably conveys combustion residues to the ash removal augers.
The air-cooled, moving stepping grate enables constant output even with different fuel types – in an adapted high-performance version, it is even suitable for base-load operation.
The feeding system of the HDG Compact ensures that the fuel is continuously and safely conveyed onto the grate. The rotary feeder decouples the combustion from the fuel store and thus offers maximum back burn protection. The automatic reversing device prevents damage caused by foreign bodies. Due to the direct fuel input and the high-quality gear design, quiet operation with low energy costs is thus achieved.
The combustion grate is the decisive component in achieving optimum emission values. The stepping grate technology enables low-emission combustion with high efficiency – even with changing fuel properties. A high-performance stepping grate is optionally available for base-load operation.
The unique combustion chamber temperature sensor ensures steady operation in the optimum power range even with changing material and protects the components by limiting the combustion chamber temperature. Together with the lambda sensor, this also guarantees consistently low emissions.
Vertical heat exchanger surface areas with a high self-cleaning effect, combined with cleaning turbulators as standard, ensure ideal heat transfer. For cleaning, the close-fitting and flat turbulators are moved to free the heat exchanger surface areas from flue ash.
Ash removal augers transport the ash into the 80-litre external ash containers. Here, the accumulating ash is compressed – this extends the emptying intervals. Ash bins with 140 or 240 litres capacity are also available on request.
The new ash container with Euro receptacle from HDG can be transported directly with any standard tractor. The advantages: The mechanical drain saves time and money, the huge filling volume (230 litres) reduces the emptying intervals.
