Abstract

Folding condensing boiler with four heat exchangers, a separator water and mist, characterized in that an exchanger heat exchanger (3) is attached to the exchanger heat (2) and constitute one unit.

Description

Description of the invention

The subject of the invention is a condensing boiler for heating liquids with flammable gases, especially natural gas in CO installations.

Known constructions of condensing boilers either do not have an additional heat exchanger for heating the flue gases and reducing their relative humidity, and in the device according to patent 169358 it is located in a quite distant place, which increases the dimensions of the boiler and increases the resistance to flue gas flow through the boiler. Another disadvantage of the known solutions is the lack of elements protecting the burner against condensate drops running down onto it or they are not effective enough.

In the boiler according to the invention, the heat exchanger in which the flue gases flowing from the separator into the chimney are heated, is combined in one unit with the heat exchanger for pre-heating the return water. The still warm flue gas flowing from the heat exchanger that reheats the water to the temperature set on the thermostat, heats both the flue gas flowing from the separator into the chimney and the return water. The furnace chamber has been equipped with additional containers that protect the burner against condensate falling on it and allow it to evaporate.

Thanks to these improvements, the boiler according to the invention obtained even more favorable operating parameters and its dimensions were significantly reduced. Since the boiler achieves a very high thermal efficiency, it burns less gas and therefore also emits less fumes. So it is not only very economical, but also extremely ecological.

The subject of the invention is shown in an exemplary embodiment in the enclosed schematic drawing in an axial section. The boiler according to the invention consists of four heat exchangers 1, 2, 3 and 4, a water and mist separator 5, a supply pipeline 6 and a water discharge pipeline 7, a sealed furnace chamber 8 with a burner 9 installed in it. there are two sets of suitably shaped condensate containers: upper containers 10 covering the burner 9 and lower 11 located in the immediate vicinity of the burner. The upper containers 10 have cutouts 13 in the side walls 12 for the flow of excess condensate into the lower containers 11. The lower containers 11 are connected to each other and have an overflow pipe 14 for draining excess condensate from the inside of the boiler to the outside.
