Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further

This multifunctional horizontal water heating furnace has a main heating water tank 5 around the body of furnace upper half, as shown in Fig. 1 . Just above the middle of the furnace body is a coal filling port, and a sealed high-pressure furnace cover is installed outside the coal filling port. As shown in Figure 1, the main combustion chamber 6 is under the main heating water tank 5, and the front of the main combustion chamber 6 is an ignition door 7, and there is a fire outlet 26 on one side of the main combustion chamber 6, and there is a discharge door 26 around the main combustion chamber 6. Trachea8. The outside of the exhaust pipe 8 is an exhaust chamber 9, and the exhaust chamber 9 is connected with the chimney 19 through the exhaust pipe 24.

Below the body of furnace is the boiler base 11, and the front of the boiler base 11 is three air intake and slag removal ports, and the three air intake and slag removal ports are successively slag discharge vents 10, dust removal vents 13, and dust removal holes 14. The slag discharge vent 10 is the air inlet of the main combustion chamber 6, the dust removal vent 13 is the air inlet of the secondary combustion chamber 27, and the dust removal hole 14 is the dust removal port of the flue. Above the slagging vent 10 of the main combustion chamber 6 is a fire bar, and the top of the fire bar is connected with the main combustion chamber 6 .

When the induced draft fan 20 starts to work, the wind outside the furnace body will enter the main combustion chamber 6 from the slag discharge vent 10, and then enter the auxiliary combustion chamber 27 through the fire outlet 26 of the main combustion chamber 6, and the fuel will be discharged in the auxiliary combustion chamber. 27 for secondary combustion, the unburned gas will be burned inside, and the fuel will be more sufficient after two combustions, and the heat will be exchanged in the heat exchanger. The secondary combustion chamber 27 communicates with the flue, and the flue is set in two sections or more than two sections. The multi-stage design of the flue allows the flue gas to exchange heat with the water in the auxiliary heating water tank 17 for a long time. An induced draft fan 20 is installed on the chimney 19 to provide power for the flue gas so that the fuel is fully burned.

The coal on the main combustion chamber 6, the coal filling port is a high-pressure closed furnace door, and the closed oxygen cannot enter the main combustion chamber 6, so the coal on the main combustion chamber 6 cannot burn. The temperature in the main combustion chamber 6 is very high, and the fuel is easily developed into combustible gas, which flows into the secondary combustion chamber 27 of the heat exchanger for secondary combustion, and the induced draft fan 20 provides power for the combustible gas. When the combustible gas passes through the auxiliary combustion chamber 27, a certain amount of oxygen is brought in from the dust removal vent 13, and a small amount of ash or dust falls on the cavity of the dust removal vent 13. The secondary combustion chamber 27 gas enters the third cavity through the U-shaped flue 15, and the ascending flue 16 is installed above the cavity where the dust removal hole 14 is located. When the combustible gas passes through the cavity where the dust removal hole 14 is located, smoke and dust will fall, which further makes the smoke coming out of the chimney 19 cleaner.

As shown in FIG. 2 , the main heating water tank 5 and the auxiliary heating water tank 17 communicate with each other through the communication chamber 25 on the outer wall. The bottom of one of the water tanks is provided with a sewage outlet 22 , the water inlet 23 is located at the bottom of the auxiliary heating water tank 17 , and the water outlet 21 is located on the side wall at the top of the auxiliary heating water tank 17 . A circulating water pump is installed at the water outlet 21, so that hot water can be circulated in the radiator. The upper part of the air collecting bag 2 is connected with a steam pipe 1, which can be used for humidifying the indoor air.

When the temperature of the heat exchanger reaches, the induced draft fan 20 stops working. At this moment, the air flow in the flue in the heat exchanger is very small, and the heat of the main combustion chamber 6 is very high, which will form a high pressure. If do not emit in time just have fire to wear out, at this moment the exhaust passage in this patent plays a role. The high-pressure gas in the main combustion chamber 6 directly enters the exhaust chamber 9 along the exhaust pipe 8 , and the exhaust chamber 9 is connected with the chimney 19 through the exhaust pipe 24 . The pressure of the main combustion chamber 6 has been reduced, and the fire cannot leak out.
