CN2272528Y - Oxygen supplying combustion device for boiler - Google Patents

Abstract

The utility model relates to an oxygen supplying combustion device for a boiler. The utility model adopts the structure that a high-temperature combustion chamber is connected with identical gas distributing pipes which are distributed in the shape of a door, and jet exhausts are evenly distributed on the gas distributing pipes; under certain pressure, the oxygen is jetted into the high-temperature combustion chamber by the steam of the boiler; under high temperature, the steam can generate combustible gas and unburned coal; inversely, the purposes of increasing oxygen and increasing combustion are achieved. The device utilized has the capability of raising the temperature of the boiler by 300 to 500DEG C and saving the coal by 30%, and has strong popularization value.

Description

Boiler oxygenation increases burning device

The utility model relates to a kind of boiler oxygenation and increases burning device, and specifically, it is the oxygen supplying combustion device device to single stove.

Boiler burning of coal now is insufficient, furnace temperature is low, waste a large amount of energy, and contain a large amount of harmful substances in the coal smoke of boiler emission, serious environment pollution, also published relevant boiler oxygenation combustion-supporting apparatus on China's utility model patent communique, but the boiler oxygenation identical with this structure increases burning device, not seeing had the publicity report.

The purpose of this utility model provides a kind of simple in structure, and cost is low, and the effective boiler oxygenation of oxygen enriching burning-aid increases burning device.

Task of the present utility model is achieved like this, and it connects on the case in the boiler high temperature combustion chamber and is " Jiong " shape and is provided with gas-distributing pipe, is distributed with puff prot on the gas-distributing pipe equably, and steam sprays in high temperature combustors from puff prot, to reach the purpose that adds oxygen and aiding combustion.

Following structure drawings and Examples are come the utility model done and are described in further detail:

Accompanying drawing 1 is the utility model structural front view.

Accompanying drawing 2 is this product new structure vertical view.

With reference to accompanying drawing, the utility model boiler oxygenation increases burning device by air inlet pipe (1), gas-distributing pipe (2) constitutes, gas-distributing pipe (2) is connected in air inlet pipe (1), gas-distributing pipe (2) is " Jiong " shape and distributes and to be arranged on the boiler high temperature combustion chamber and to connect case (4) on every side, dividing equably on the gas-distributing pipe (2) has puff prot (3), leaves exhaust outlet (5) at the two-end-point of gas-distributing pipe (2).The steam that utilizes boiler to produce, under certain pressure, steam is spurted on the fire grate (6) of high temperature combustors from the puff prot (3) that gas-distributing pipe (3) distributes, HCS at high temperature reacts with unburned coal, produce fuel gas, fuel gas fully burns with oxygen again, reaches to add oxygen and aiding combustion, improves the purpose of the thermal efficiency.

The utility model is simple in structure, and cost is low, and through installing and using test, furnace temperature improves 300-500 ℃, and economizing on coal reaches 30%, because the abundant burning of coal, makes to enter that coal significantly reduces because of middle harmful substances is arranged in the air, has improved environment.The utlity model has extremely strong popularizing value.

Claims (2)

1, a kind of boiler oxygenation increases burning device, it is by air inlet pipe (1), and gas-distributing pipe (2) constitutes, and it is characterized in that gas-distributing pipe (2) is connected in air inlet pipe (1), gas-distributing pipe (2) is arranged on the boiler high temperature combustion chamber with " Jiong " shape and connects on the case (4), is distributed with puff prot (3) on the gas-distributing pipe (2) equably.

2, boiler oxygenation as claimed in claim 1 increases burning device, it is characterized in that the two-end-point of gas-distributing pipe leaves exhaust outlet.
