Description

Heating boiler. The invention relates to a boiler for low-pressure steam heating and hot water heating, which can also be used as a hot water supply boiler can and is mainly intended for smaller apartments: but it can also be used anywhere be set up in a beneficial way where the existing central heating system works uneconomically due to too large boilers or not due to lack of coal can be fully exploited. The boiler is light and easy to transport.

Gaseous fuels are initially considered for heating, but the facility can also be made so that liquid and solid fuels Can be used.

The boiler is divided into several heating chambers connected by special trains divided, in which inclined limbs are housed with only a small amount of water are. The essence of the invention is that these chambers are both parallel can be operated switched, each being heated immediately, as well connected in series, with only the first chamber immediately is heated. This enables quick heating and easy adjustment to changing heat demand.

The drawing shows an embodiment of the subject matter of the invention shown, namely Fig. i shows the boiler in a vertical longitudinal section, Fig.2 in side view, Fig. 3 in a mustard cross-section and Fig. 4 in a horizontal section according to the line ra-b in Fig. i.

The boiler has water sections C coupled at an angle in the two heating chambers AA, which are separated by the draft duct B to be described later.

The jacket S of the furnace, including the ceiling, enclosing the heating chambers AA is hollow and filled with heat protection material so that no heat can be lost to the outside. In the base L of the boiler carrying the jacket S, a burner H is accommodated, which comes into operation under both chambers AA, but usually only under one of the two chambers, for faster heating of the boiler and when there is a high demand for heat.

The coupled water links C are at the top by connectors E with the steam collector D, below by connecting pieces El with the return pipe G connected.

Inside the base L (Fig. I and 3) there is a continuous one at height x Chamber bottom Al created under both chambers A. The hollow Winkelzugkanal B sets closes tightly on the floor A1.

The entry of the heating gases from the first chamber into the hollow Winkelzug B or in its leg B1 (Fig. Q.) Takes place above at U (Fig. I). In height Ir (Fig. 3) is where the heating current enters from duct B to the second Heating chamber.

The front and sides of the boiler are located inside the base L, directly above chamber floor A1, air control slide P and air holes PI for the Air supply.

The first chamber is connected to a secondary exhaust TV, with the main exhaust W on the upper rear of the boiler through a throttle valve or a trigger slide Y connected. The purpose of this is that when both chambers pass through the burner at the same time H are to be heated, a deduction can also take place from the first chamber.

There is a steam collector D to feed the water elements C Filling valve 0. On the steam collector there is also a nozzle N for any used Standpipe and a pressure gauge M connected.

The steam collector D is connected to the burner tap K via an automatic pressure regulator J to regulate the pressure. A water level pipe in connection with the water elements can indicate the level of the water.

The connection with the radiators is made by the steam collector D outgoing pipe F and through the to the connecting pieces El of the water links C connected return pipe G made. A closable drain connector T in the return pipe G is used to empty the boiler.

After commissioning, paint the rising from the burner H. Heating gases the inclined heating surfaces of the water sections C, which they are in the whole Pull through height.

The heating current from the first chamber goes into the top at U (Fig. I) hollow Winkelzugkanal B, namely first down in the leg B1, goes then at an angle into leg B. to step into the second heating chamber at f "1 and pull it into the main trigger W (Fig. i to q). The secondary deduction is IV, closed.

In this mode of operation, the burner H only burns in the first chamber - the air holes of the second canoeist then remain closed -. Otherwise, so if the boiler is heated up quickly, the burner burns in both chambers, the control slides are then set to air supply in both chambers and the secondary vent W is open. Any number of heating chambers can be combined get connected.

To switch off the gas supply to the right chamber, a .gas valve piece Z inserted immediately in front of the right ventricle.

The burner set up for gaseous fuels can be connected to any Connected to the mains or fed by an acetylene gas generator.

Claims (1)

PATENT CLAIM: Heating boiler with several separately heatable chambers, characterized in that the chambers (A) can be operated in parallel, whereby they are all heated directly and the heating gases are discharged from each chamber into the fume cupboard (W), as well as connected in series , whereby only the first chamber is heated directly and the heating gases drawn off from it above are fed through the hollow chamber partition wall (B) to the following chamber.
