1.燃油鍋爐燃燒器的布置
1. Arrangement of Burners for Oil-fired Boilers
目前,快裝式燃油鍋爐要求爐子體積小,熱負荷高。 主要措施有兩點:是提高燃燒器的霧化質量,第二是提高燃燒器出口的風速,使內部氣流更加混合。 強大。 氣流的橫截面減小并且燃燒很強,因此燃燒器的布置與爐子的熱負荷密切相關。 小型燃油鍋爐都是單燃燒器,根據煙氣沖程的方向排列在立式鍋爐的頂部或底部。 通常,臥式快速安裝的火管鍋爐配備有1?2個燃燒器,并水平放置。
At present, fast-loading oil-fired boilers require small furnace volume and high heat load. There are two main measures: the first is to improve the atomization quality of the burner, and the second is to increase the air speed at the burner outlet to make the internal air flow more mixed. Powerful. The cross section of the air flow decreases and the combustion is very strong, so the arrangement of the burner is closely related to the heat load of the furnace. Small oil-fired boilers are single burners, arranged at the top or bottom of vertical boilers according to the direction of flue gas stroke. Usually, the horizontal fast-installed fire tube boilers are equipped with 1 or 2 burners and are placed horizontally.
將水管鍋爐或燃煤鍋爐改為燃油鍋爐。 燃燒器中心與側壁的距離應不小于1?1.2m,下部燃燒器爐底的距離應不小于1m; 如果使用兩個燃燒器,則中心之間的距離也應保持約1m,并且兩個燃燒器的轉向應相反。 當單個燃燒器的油耗為500?1000kg / h時,爐深不少于4m; 燃油消耗當溫度為200?500kg / h時,爐深不小于3m。
Change water-pipe or coal-fired boilers into oil-fired boilers. The distance between the center and the side wall of the burner should be no less than 1 1.2 m, and the distance between the lower burner and the bottom of the furnace should be no less than 1 m. If two burners are used, the distance between the center should be kept about 1 m, and the steering of the two burners should be opposite. When the oil consumption of a single burner is 500-1000KG / h, the furnace depth shall not be less than 4m; when the oil consumption is 200-500kg / h, the furnace depth shall not be less than 3m.

2.燃氣鍋爐燃燒器的布置
2. Arrangement of Gas-fired Boiler Burners
鍋爐爐的大小和形狀與燃料特性密切相關。 燃氣鍋爐的燃燒過程比燃料簡單,燃燒所需的時間較短,所需的爐膛體積較小。 燃燒器的布置應與爐子的形狀結合起來考慮。 火焰已滿,火焰未被水冷壁沖洗。 燃氣鍋爐通常裝有燃燒器,系統(tǒng)簡單,操作管理方便,節(jié)省投資。 對于大容量的燃氣鍋爐,可以布置兩個燃燒器。 通常,采用上下布置,即使減輕負載,停用一個燃燒器也不會導致火焰偏離爐膛中心,從而影響水循環(huán)的可靠性和過熱器的溫度偏差。
The size and shape of the boiler are closely related to the fuel characteristics. The combustion process of gas fired boilers is simpler than that of fuels. The combustion time is shorter and the furnace volume is smaller. The arrangement of burners should be considered in conjunction with the shape of the furnace. The flame was full and the flame was not washed by the water wall. Gas-fired boilers are usually equipped with burners. The system is simple, easy to operate and manage, and saves investment. For large capacity gas-fired boilers, two burners can be arranged. Usually, if the upper and lower arrangement is adopted, even if the load is reduced, the shutdown of a burner will not cause the flame to deviate from the center of the furnace, thus affecting the reliability of the water cycle and the temperature deviation of the superheater.
由于結構上的限制,殼式鍋爐以對稱的水平排列的雙爐布置。 每個燃燒器都配有一個燃燒器。 燃氣鍋爐燃燒器可以安裝在鍋爐的前壁和底部。 如果煙氣出口在爐子的底部,則可以將燃燒器放在爐子的頂部。
Due to structural constraints, shell boilers are arranged in a symmetrical horizontal arrangement with two furnaces. Each burner is equipped with a burner. Gas-fired boiler burners can be installed on the front wall and bottom of the boiler. If the flue gas outlet is at the bottom of the furnace, the burner can be placed at the top of the furnace.
