Description
The SZL Coal-Fired Steam Boiler is designed for larger industrial facilities with steam demand above 6 tons. Its double drum structure provides a larger heating surface area while keeping the equipment layout relatively compact, supporting high-load and continuous steam supply. The boiler uses a chain-type fuel feeding and combustion system with separate air chamber design to support coal combustion during long operating hours. It is suitable for regions where coal supply is stable and economically practical. Use of this boiler should be planned with appropriate emission management and local regulatory compliance.
