Boilers Furnace efficiency rates

Low losses combined with low energy demand and optimum controllability enable the most economical operation which to days technique. The three-pass boiler is robust and economical.

The furnace is formed by the fire tube.The flue gases are directed through topped smoke tubes where they are cooled down. As it has proved to be especially economical to lead the flue gases through three passes most of the large water space boiler built today belong to this type –hence the nameٌ three-pass boilersٌ.

Because of its constructional design the three-pass boiler is especially suitable for the combustion of liquid or Gaseous fuels.
