Description

Gaa boiler

The innovation concerns a gas boiler, consisting of from a shaft with at least partially luasaevleitenden Side walls, one arranged in the upper area Heating register and a burner located in the lower, ventilated area.

Gas boilers of the type mentioned are generally known and meet the demands to be made of them, even though these are today at home and abroad Requirements have been expanded to the effect that the lower area, i.e. the area to be set up on the floor The area should not reach excessively high temperatures. There are already measures in this regard taken to this effect, the sides up to

underneath the burner area a water-bearing, i.e. double-walled, uelche measure bend dee Labor and material costs

for larger gas heating

Keeseln in the articulated structure is justified. For smaller gas boilers, those in the upper area with a heat exchanger in the form of one of several Tubes formed Heizregiatera are provided, the effort is drawn down below the burner area, water-carrying side walls to the radiant heat of the burner sitlich and down, aua the Discharge lower area, relatively high, and the present innovation is based on the task of improving a Gaeheizkeasel of the type mentioned to the effect of using simple means the area below the burner for discharge to make the radiant heat more suitable.

This object is .τι it a gas boiler of the type mentioned according to the innovation achieved in that the shaft below the burner with a with inlet air openings; provided bottom is completed, which is thermally connected with at least a part of its side edges with the downwardly extended, non-uiasaerleitenden surfaces of the water-bearing cross winds.

Advantageous further training results from the Subordinate claims.

This novel design of the area below the burner catches the inserted base, which is also advantageously shaped at the same time can be formed by calf feet, bias even closer is described, the downward radiant heat and conducts it, as it conducts heat at least one side wall connected to this further. Since the floor is provided with ventilation openings part of the combustion is also ventilated through sucked the ground so that it can be cooled on the one hand, but also preheated air can be fed to the burner on the other hand.

The novel gas boiler and its advantageous circuit formation farms according to subclaims are explained in more detail below with reference to the graphic representation of an exemplary embodiment.

As can be seen from Fig. 1, 2, the gas boiler or its shaft below the burner 2 is closed with a base k , which is provided with air inlet openings and with upwardly curved embossments 13 on which the condensate collecting pan 8 is arranged.

Opposite edges 5 ^{1 of} the bottom U are bevelled and formed at 11 feet. This floor k is thermally conductive with the non-water-bearing cross winds 6,7 'as well as through
