Heating boiler

The innovation concerns a boiler for liquid or gaseous Fuels with a combustion chamber and flue gas flues leading from this to a flue gas nozzle and a itself when the burner starts up due to sudden occurrence a so-called explosion flap that opens a large amount of smoke gas.

The In operated with liquid or gaseous fuels Flue gases produced by boilers are guided through flue gas flues and fed to a flue gas nozzle. This one stands via a flue gas raw r with a chimney 1 i. Connection. Trains are designed or dimensioned in such a way that the hot flue gases contain as much heat energy as possible to increase the heating capacity is withdrawn.

When the burner starts up, this occurs suddenly per tent unit a much larger amount of flue gas than during the

burning times. The smoke casings are designed so that they only those incurred during normal drilling operations per unit of time be able to discharge significantly smaller amounts of flue gas smoothly, i.e. with a uniform outflow velocity.

In order to control the large amounts of flue gas that suddenly arise when the burner starts up, there are on the outside of the boiler usually in the area of a door, so-called explosion flaps arranged through which these amounts of flue gas evaporate and get into the boiler room. This creates a considerable odor nuisance in the boiler room and often also in the surrounding rooms.

It would be possible to design the flue gas ducts so large that The deflagrating flue gases can also be effectively discharged via this be able; in this case, however, during normal firing operation very unfavorable conditions arise because the flue gas passes are overdimensioned for the flue gas quantities that then arise would be. That's why one usually takes the at Deflagration of the flue gas during the start-up of the burner resulting in odor nuisance in purchase to be economical To ensure conditions during normal burning operation.

It is the task of the innovation to create a boiler of the type mentioned, in which during the start-up of the burner there is no odor nuisance and that with regard to its heating efficiency is on a par with known boilers.

T he ^ θ object is achieved with a boiler of the stated type, which is arranged according to the innovation in a ^r üffnungsrichtung behind the ExpIosion kIappe Rauchgassamme I chamber, which is connected to the flue gas stack, comprising.

Further details, features and advantages of the innovation result can be derived from the following description of one in the Implementation example shown in the drawing.

¹ I * 1

A boiler 10 includes a combustion chamber 12 with flue gas flues 14 is in connection (not shown). The flue gas flues 14 open into a flue gas collection chamber 16. An this is connected to a flue gas nozzle 18, which has a (not shown) flue gas pipe with a (also not shown) chimney is connected.

An outflow channel 20 provides a direct, below the flue gas passages 14 lying connection between the combustion chamber 12 and the flue gas collection I chamber 16.

The outflow channel 20 is in the region of its confluence with the Flue gas collection I chamber 16 provided with an explosion flap 22, which opens into the flue gas collector I chamber 16.

The Rauchgassamme I chamber 16, the explosion flap 22 and the Flue gas flues 14 are easy due to a cleaning flap 24 access lent.

During the normal burning operation of the boiler 10, the flow Flue gases that form in the combustion chamber 12 via the flue gas flues 14 and pass through the flue gas collection chamber 16 into the flue gas nozzle 18 and from there over in the direction of the arrow a flue gas pipe in the chimney. The explosion door 22 is in closed in this operating state.

When the burner starts up, a very large one suddenly arises Flue gas quantity and thus an overpressure in the combustion chamber 12, which is in the outflow channel 20 and in the flue gas flues 14 continues. Since this overpressure is not reduced quickly enough due to the small cross section of the flue gas flues 14 is, the explosion flap 22 is opened, and the under Excess pressure flue gases deflagrate into the flue gas collector I-chamber 16. The explosion flap 22 closes by its own weight automatically after the overpressure has been relieved.

^A particular advantage of the Neuerunn is that the gas that deflagrates from the explosion flap is now immediately discharged to the chimney without getting into the heating system. This eliminates unpleasant odors when operating boilers supplied with liquid or gaseous fuels.
