Air type incinerator, based on one-sided premixed incineration technology plan, is called air type incinerator.
Definition and truth
According to the one-sided premixed incineration technology plan, the incinerator is called atmospheric incinerator. The primary atmosphere coefficient is 0 < α < 1. The principle of the atmospheric incinerator: under certain pressure, the gas is ejected from the nozzle at a certain flow rate, and enters the suction compression pipe. The gas inhales the atmosphere by its own energy. The gas and primary atmosphere are mixed in the ejector, and then the gas flows out through the fire hole at the head to burn, causing Bunsen flame.
Constitute one side
The atmospheric incinerator is composed of two sides: the head and the ejector.
classification
The atmospheric incinerator always exerts the primary atmosphere of gas injection, so it belongs to the injection incinerator. According to the difference of gas pressure, it can be divided into two types: low pressure injection and high (medium) pressure injection. The former is mainly used for civil gas appliances and the latter for industrial assembly.
Features and application limitations
benefit
1. It has shorter flame, stronger fire power and higher combustion temperature than the natural induced draft decentralized incinerator.
2. It can burn the gas with different natures. The combustion control is complete, the combustion is subject to high control, and the CO content in the flue gas is low.
3. Be able to use low-pressure gas, because the atmosphere relies on gas inhalation, so there is no need for air supply buildings.
4. Strong compliance, able to meet the needs of many processes.
Disadvantage
1. Because only one-sided atmosphere is premixed, rather than all the atmosphere required for incineration, the heat intensity and incineration temperature of the fire hole are higher than those of the natural induced draft decentralized incinerator, but they are still limited, which still cannot meet the needs of some processes.
2. When the heat load is large, the layout of multi hole incinerator is heavy.
Application limitations
The multi fire hole atmospheric incinerator is the most widely used. It is also widely used in gas appliances such as domestic stoves, water heaters, boiling water appliances and canteen stoves in family and public miracles. It is also used in small steam pots and industrial stoves. Single fire hole atmospheric incinerator is widely used in small and medium-sized steam boiler and some industrial furnaces.
