What do you know about boiler incinerators?Boiler incinerator is the fuel and incineration required air, according to a certain share, speed and mixing method, through the nozzle into the furnace.Incinerator effect: fuel and air required for incineration, according to a certain share, speed and mixing method, through the nozzle into the furnace.1, ensure that burn quickly and energetic 2, can be a very good habit is running in the process of load change and the change of coal 3, reduce the formation of NOx, satisfied with the environmental protection ultra low emission requirements classification of burning: a, dc incinerator exit airflow for dc jet, the general layout in the corners of the hearth, the pulverized coal air flow in the chamber of a stove or furnace burn inscribed circle.1, pulverized coal precombustion chamber incinerator this is China's earliest research, the most widely used new pulverized coal incinerator equipment.The precombustion chamber incinerator is a precombustion chamber made of refractory materials or heat-resistant steel plates.2, blunt incinerator it is in the corner of the type of pulverized coal incinerator each corner of the outlet of the primary air nozzle, set a non-flow line object - blunt body, so that the pulverized coal flow in the wake area of the blunt body reflux, entrainment high temperature smoke, in favor of fuel ignition and flame stability.After the fire, the coal torch in the furnace formed a four-angle cut circle burning.3. The structure of flame stable combustion ship incinerator is that a ship-shaped flame stabilizer is installed in the primary tuyere of the conventional direct current pulverized coal incinerator, and a small oil gun is set at its center.After selecting this structure, the upper pulverized coal gas flows around it and into the furnace, forming a beam waist jet not far from the primary air nozzle.The outer edge of both sides of the girdle waist forms an area with high temperature, high pulverized coal concentration and appropriate oxygen concentration, which becomes an outstanding ignition heat source for igniting pulverized coal airflow and then burns in the stable furnace.4, thick and weak incinerator so-called thick and weak incinerator, is to choose the pulverized coal - air mixture airflow, namely the first air flow separated into rich powder flow and poor powder flow two airflow, so that the total air volume of the first wind unchanged to improve the concentration of pulverized coal in rich powder flow.The outlet airflow of the cyclone incinerator includes a rotary jet rotating around the axis of the incinerator.Airflow rotation will form a low pressure area in the center of jet flow, and then absorb the high temperature flue gas in the gap, which is suitable for coal with higher volatile content.Today xiaobian for everyone to share so much, no matter what kind of incinerator, the ultimate purpose is to make coal better, cleaner burning.However, the direct current incinerator creates a power field in the furnace and rotates the air in the furnace by means of circular cutting to attract the surrounding high-temperature smoke to participate in the incineration.The cyclone incinerator is designed to disturb the air, and then make the pulverized coal air full of mixture, conducive to incineration.
