Definitions

the invention relates to a gas boiler with a burner without fan with partial load control, consisting of a combustion chamber with overlying heat exchanger elements forming the boiler block, in the wall of which a venturi tube with a nozzle and an air flap are arranged, via which portions of the air required for the combustion in each case the combustion chamber are sucked in.
the aim of the present invention is to provide a gas boiler of the type described, which allows safe adjustment to optimum burning behavior in a technically simple and therefore inexpensive manner and thus ensures an improvement in the boiler efficiency.
the invention consists in that the combustion chamber open against the heat exchanger elements on its further walls and the air flap on its edges are sealed tightly against the inflow of false air into the combustion chamber, the venturi tube limiting the cross-section of the combustion air inflow to a fixed subset of the air quantity required at full load operation has and an opening is provided in the air flap, which is calibrated to the inflow of the differential air quantity, which is required in addition to the inflow of air through the Venturi tube for the optimum effectiveness of the burner in the desired part-load operation.
the invention provides a gas boiler, which allows the burner to be safely set to optimal burning behavior in a technically simple and therefore inexpensive manner and at the same time ensures an improvement in the boiler efficiency, while considerably reducing the downtimes by adapting the burner output to the respective requirements and thus the deployment losses can be significantly reduced.
the venturi tube has a cross section through which the air supply to the combustion chamber is limited to a proportion between 1/3 and 2/3, preferably to less than half, of the air quantity required at full load operation, in the air flap a window opening is arranged, in which an exchangeable, the calibrated bore aperture screen is held at its edges to seal against leakage of air leakage.
the calibrated opening or the calibrated openings are expediently arranged in the air flap in the front wall of the housing that also carries the burner, but instead of the calibrated hole arranged in the front wall of the housing or in addition to this hole in another housing wall and optionally distributed over several different housing walls in Different height and side positions calibrated holes are provided, with the help of which an optimization of the burning behavior of the boiler can be achieved according to the respective local or factual conditions.
the gas boiler shown in the drawing essentially consists of a combustion chamber 3 enclosed by the housing wall 2 with overlying heat exchanger elements 1 forming the boiler block.
the burner 4, a venturi tube 5 with nozzle 6 and an air flap 7 are arranged in the housing wall 2, are drawn into the combustion chamber 3 via the respective partial quantities of the air required for the combustion.
the venturi tube 5 having a cross section which limits the combustion air inflow to a fixed subset of the air quantity required at full load operation and in the air flap 7, which is sealed at its edges by sealing strips 8 against the inflow of false air into the combustion chamber, an opening 10 is provided, which is calibrated to the inflow of the differential air quantity into the combustion chamber 3, which in addition to the quantity of air flowing through the Venturi tube ensures the optimum effectiveness of the burner is required for the desired part-load operation.
the air supply to the combustion chamber 3 is limited via the venturi tube to a proportion between 1/3 and 2/3, preferably to less than half of the amount of air required at full load, it is in the air flap 7, a window opening is arranged, in which an exchangeable diaphragm disk 11, which has the calibrated bore 10, is held at its edges, sealing against the passage of false air.
calibrated holes can be provided in another housing wall and optionally distributed over several different housing walls at different heights and sides.
