Tobacco processing industry is an energy intensive industry, especially with a high demand for steam during baking and humidification processes. During the production process of tobacco re-curing, a large amount of steam is usually required to meet the process requirements such as moisture regain and drying. These processes have strict requirements for the stable supply and quality of energy, which can directly affect the quality of final products. Therefore, it is crucial for tobacco factories to choose a boiler system that can meet the high load operation requirements and fully realize energy utilization. A tobacco factory located in Surabaya, Indonesia faces the dual challenge of improving production efficiency and reducing energy consumption and emissions. zhongde Boiler provided a solution of a 6-ton DZL series coal fired steam boiler based on the specific needs of the tobacco factory. This boiler not only meets the steam demand of the factory, but also demonstrates high efficiency and environmental protection during operation. zhongde Boiler fully considered the climate characteristics of Surabaya, Indonesia and the types of fuel available locally when designing this boiler to ensure that the boiler can operate stably under changing environmental conditions.

This DZL series coal fired steam boiler from zhongde Boiler adopts a unique water fire tube three passes design, fundamentally solving the problem of tube plate cracking in pure fire tube boilers, ensuring the safety and stability of boiler running. At the same time, the boiler fire tube adopts a high-efficiency heat transfer element threaded smoke tube, which has a heat transfer coefficient 1.8 times higher than ordinary smoke tubes. That can effectively enhance the heat transfer effect and make the thermal efficiency of the boiler reach over 82%. Moreover, this boiler has high degree of intelligence equipped with an intelligent control system, simple running way, and strong reliability. In addition, this series of steam boilers are transported from the factory as a whole, which has the advantage of easy installation and saves infrastructure investment. After the boiler components are transported to the site and in place, they can be connected to pipelines, valves, smoke and air ducts, and control circuits and put into operation. The pictures shows the boiler production has been completed and is ready for delivery.
