Coal Fired Boiler (DZL)

Product Description

The structure & characteristic of DZL series travelling grate stoker steam/hot water boiler 1、Uses the thread smoke tube instead of plain tube, the heat transfer effect 2、The distinctive secondary air design eliminates the dead angle of combustion area, and makes combustion more plenitudinous 3、rational air distribution and infinitely variable speed transmission, travelling grate can work at discretional speed in setting range, 4、Thicken fire grate segment is high-intencitive and long maintenance intervals and it’s useful life is more longer, 5、All-welded tube plate no relaxations and leakage. 6、Big diameter water wall, good circulation and lower need to water quality. 7、Light boiler settings is elegant appearant and economical for carriage. 8、mechanization of running , lower people’s working intensity , labor-saving machinery 9、Stainless steel water pump, failure rate is lower and the ues life is longer. *0、compact in frame、small floor space and low investment *1、package boiler makes installation is more convenient and the equipment be run into operation quickly 序号 名 称 item符号 单位 数 据 date DZL*-AⅡ-Ⅱ DZL*-AⅡ-Ⅱ DZL*-AⅡ-Ⅱ 蒸发量Rated steam outputD t/h 1 2 4 2工作压力Rated working pressure P Mpa 0.8/1.0/1.3/1.6/2.5 3蒸汽温度（饱和）Rater steam temperature t ℃ **5/**4/**5/**4/**4 4给水温度 inlet water temperature tgs ℃ *0 *0 *0 5受热面积Heating surface area m2 锅炉本体boiler body heating area m2 *9.4 *9.*4 **7.3 省煤器（铸铁）economizer heating area m2 *3.*6 *3.*6 *3.6 6炉排面积 traveling grate surface R m2 2.2 3.2 4.*7 7试验压力hydrostatic test pressure Ps Mpa 1.2/1.4/1.7/2.0/3.**5 8 water volume V t 2.5 5.5 8.6 9 Thermal efficiency Designed efficiency η % *4.7 *5 *5 *1 Boiler installation Dimensions (L × W × H) Boiler’s overall dimension after installation ***0×***0×***4 ****0×***0×***0 ****0×***0×***0 *2 Boiler large transport size (L × W × H) Boiler’s overall dimension for transportation ***5×***0×***4 ***0×***0×***6 ***0×***0×***6 *3 Shipping Weight large boiler Max weight for transportation t ≈*5 ≈*5 ≈*2
