In the industrial boiler sector, model codes represent the core technical parameters of the equipment. For many enterprises seeking a stable and cost-effective heat source, selecting a reliable SZL10-1.25-AII chain grate coal-fired steam boiler manufacturer is the starting point of a successful project. In this model designation, “SZL” refers to a double-drum longitudinal chain grate boiler, “10” indicates a rated evaporation capacity of 10 tons per hour, “1.25” represents a rated working pressure of 1.25 MPa, and “AII” specifies that the applicable fuel is Class II bituminous coal.

With moderate capacity and mature combustion technology, this type of boiler is widely used in industries such as textile dyeing, building materials, and food processing. In regions like Central Asia and Southeast Asia, where coal resources are abundant and relatively economical, coal-fired steam boilers remain an important industrial heat source. As a result, demand continues for experienced and export-qualified SZL10-1.25-AII chain grate coal-fired steam boiler manufacturers capable of delivering stable performance under diverse conditions.

ZOZEN SZL Chain Grate Coal-Fired Steam Boiler

Why Overseas Enterprises Prefer 10-Ton Chain Grate Coal Boilers

Textile manufacturers in Tajikistan and building material producers in Indonesia often seek cooperation with a professional SZL10-1.25-AII chain grate coal-fired steam boiler manufacturer due to strict production requirements and fuel cost considerations.

In textile dyeing and finishing processes, steam stability directly affects color consistency and fabric quality. Fluctuating steam pressure or poor dryness can increase defect rates. For autoclaved aerated concrete producers, continuous and sufficient steam supply is equally critical for curing processes. Any interruption can disrupt production and impact product quality.

These companies chose ZOZEN Boiler because, as an experienced SZL10-1.25-AII chain grate coal-fired steam boiler manufacturer, it provides equipment designed to adapt to local coal characteristics while maintaining efficient and stable combustion. This balance between fuel economy and operational reliability supports continuous industrial production.

Technical Advantages of ZOZEN’s SZL Series

As a recognized SZL10-1.25-AII chain grate coal-fired steam boiler manufacturer, ZOZEN has upgraded its SZL series to address common issues such as incomplete combustion and heat loss.The boiler adopts a membrane water-cooled wall structure, enhancing furnace sealing and reducing heat dissipation. This design helps maintain stable steam quality for applications requiring consistent pressure and dryness.

The self-developed chain grate system, combined with optimized arch design and multiple independent air chambers, improves combustion efficiency. Operators can adjust air supply according to fuel conditions, increasing burn-out rate and reducing coal consumption.For overseas projects, the SZL series is delivered in assembled sections to shorten installation time and lower on-site costs, reflecting practical consideration for international customers.

With over 30 years of experience, Wuxi ZOZEN Boiler Co., Ltd. has become a globally active SZL10-1.25-AII chain grate coal-fired steam boiler manufacturer. The company holds a Class A boiler manufacturing license and has established a complete service system covering solution design, equipment supply, commissioning, and after-sales support.

From textile factories in Central Asia to building material plants in Southeast Asia, ZOZEN boilers have demonstrated stable operation and dependable performance. For enterprises seeking a technically mature and service-oriented SZL10-1.25-AII chain grate coal-fired steam boiler manufacturer, ZOZEN Boiler remains a trusted partner for long-term industrial development.
