The HHAS boiler is a superheated water boiler that is horizontal, fire-tube with three passes and steam chamber. The chamber is completely cooled by boiler water.
With thermal power from 1,500 kW to 15,000 kW, Starting at 6 and up to 16 BAR in a single apparatus, and temperatures from 110 to 220 ºC. These boilers use liquid or gaseous fuels.
It's main summed up characteristics are:
Thanks to the design and smoke tube section as well as the separation between the tubes, the HHAS boiler has good internal water recirculation. This ensures greater heat transfer and achieves low resistance to smoke passage.
As a consequence of ongoing research and the experience accumulated over more than 75 years, the HHAS boiler thanks to its insulation of great thickness and high density, as well as its insulated door design has very little loss from radiation.
The furnace design is such that the HHAS boiler has a low thermal load in the combustion chamber (less than 1.25 MW/m3) thus achieving combustion that pollutes very little.
The HHAS boiler is one of the highest performing boilers on the market: according to the pressure and fuel, it can reach 91%.
The HHAS boiler is certified in accordance with European Directive 2014/68/UE.
The HHAS boiler may be supplied (upon request) with the ATTSUTROL electric control cabinet, with built in automation. Twenty-four or seventy-two hour surveillance may be achieved.
