HOT WATER BOILER

The boilers are designed according to the well known Ygnis system of combustion : Rayol, i.e. pressurized combustion with flame reversal. The most important characteristics of this system: - uniform loading of the furnace and of the heating surfaces - independence from chimney draught - decrease of the excess of air through heat transfer from the reversing flue gases to the fuel particles - ideal starting conditions - lengthening of the burning distance - excellent burning characteristics - no need of refractory even when using heavy oil - small chimney sections
