DZL型系列鍋爐特點:Features of DZL Series Boiler 本體采用拱形管板,提高了強度安全裕度,簡化了拉撐構件。 Boiler proper adopts the arched tube plate, improving strength safety margin and simplifying the stay. 采用強化傳熱的內螺紋煙管,傳熱效果好,熱效率高。 The internal threaded fire tube has a good effect of heat transference and a high heat efficiency. 機械化燃燒,環(huán)保節(jié)能。 The mechanization combustion is environment friendly and energy sing 輔機配套齊全,整機出廠。 The auxiliaries are completely provided and the equipment is delivered as a whole. DZL系列蒸發(fā)量1000-20000kg/h 設計壓力0.7-2.45Mpa DZL Series Capacity 1000-20000kg/h Design pressure 0.7-2.45Mpa DZL系列熱功率0.7-70MW DZL Series thermal power 0.7-70MW 煙塵分離 爐膛慣性分離煙塵,原始排放濃度低于國家標準。降低煙塵排放濃度。 Smoke-dust separation The furnace separates the smoke and dust inertially. The original emission conceation is lower than the national standard, which decreases the smoke dust emission conceation. 螺紋煙管 強化傳熱,縮小鍋殼尺寸、提高柔性,從而減小管端焊縫熱應力,不積灰,防止管板開裂。 Threaded fire tube The threaded fire tube enhances heat transfer, narrows the shell size and increases the flexibility, which reduces the thermal stress of the welding seam of the tube tip and prevents the crack of the tube plate. 拱形管板 提高管板柔性,從而減小管端焊縫熱應力,取消拉撐件,防止管板開裂。 The arched tube plate The arched tube plate can increase the flexibility of the tube plate, which reduces the thermal stress of the welding seam of the tube tip. The tension brace parts are removed to prevent the crack of the tube plate. 八字煙道 降低高溫管板煙溫,從而防止過冷沸騰,減少鍋爐底部熱負荷,防止管板開裂,防止鼓包。 Wing shaped flue It can reduce the smoke temperature of the high -temperature tube plate to oid the boiling for over cold boiling. It can also decrease the heat load at the bottom of the boiler to oid the crack of the tube plate and the bumps. 承載風箱不漏煤爐排 可使鍋爐房更簡潔美觀;不漏煤爐排強化鍋爐燃燒,提高燃燒效率,提高經濟性。 No- coal -leakage grate with bellows It can make the boiler room look simple, tidy and nice. The non -leakage grate can strengthen the boiler combustion, improve combustion efficiency and be more economical. 回水引向高溫管板 提高高溫管板水流沖刷速度,降低水溫,從而防止過冷沸騰,防止管板開裂。 Return water flowing to the high temp. tube plate This can increase the scouring velocity of the current of water and decrease the water temp. to prevent the over cold boiling and the crack of the tube plate. 引射管 提高水冷壁水流速度,從而防止過冷沸騰,防止爆管。水循環(huán)更加可靠。 Induction tunnel Increase the current of water velocity to prevent the over cold boiling and the tube explosion. The water circulation becomes more reliable.
