The boiler employs an offset furnace tube wet back structure, where high-temperature flue gas sequentially washes the first and second smoke passages. It is then discharged into the atmosphere through the chimney from the rear smoke chamber. The boiler is equipped with removable front and rear smoke box lids for easy maintenance. The boiler is fitted with industrial burners of excellent technical performance, utilizing advanced technologies such as automatic proportional combustion control, automatic water regulation, programmed start/stop, and fully automatic operation. It also features high and low water level alarms, and automatic protection functions for the lowest water level, over-pressure, and extinguishing. This type of boiler boasts characteristics such as compact structure, safety and reliability, easy operation, rapid installation, low pollution, low noise, and high efficiency.

Product Features:

1. The design, manufacturing, and supervision of the boiler strictly comply with the "Safety Supervision Regulations for Steam Boilers," JB/T 10094-2002 "General Technical Conditions for Industrial Boilers," and JB/T 1619-2002 "Technical Conditions for the Manufacturing of Shell Boilers," ensuring the long-term safe and stable operation of the boiler. 2. The boiler body features a full-wet back, single-flue, three-pass fire-tube structure, with flames burning at a slight positive pressure in the large combustion chamber, fully extended. This results in low combustion heat load and minimal NOx emissions. 3. The wave-shaped furnace tube and threaded smoke tube structure enhance strength while accommodating the need for expansion in various parts. 4. All main welds are焊接 using butt joints, and are inspected by X-ray and ultrasonic non-destructive testing to ensure welding quality meets requirements. 5. The boiler has a large water volume and gas space, with strong load adaptation capability. The well-designed internal equipment ensures the steam's water content is below 4%, meeting users' high steam quality requirements. 6. A new type of thermal insulation material is used, which is lightweight, has minimal heat loss, and excellent insulation properties. 7. The water level indicator employs stainless steel as the electrode rod and polytetrafluoroethylene as the insulating material. It is inserted from above, making it less prone to contamination, reliable in performance, and long-lasting in use. 8. The front and rear smoke boxes are hinged for easy opening, facilitating quick maintenance and repairs. 9. Oxygen Content Regulation (Optional): This system successfully monitors the oxygen content in flue gas and transmits this data in real-time to the control system. Through computerized intelligent analysis, it automatically adjusts the fuel-to-air ratio of the combustion equipment, keeping it in an optimal working state, significantly improving combustion efficiency and thus greatly reducing fuel consumption.

Product Features: 1. Protection Device - The control system operates on a timed schedule, allowing the system to automatically switch to work or off-hours status through the operation of the timing function. The control system can be set to multiple timing periods within a 24-hour period. If the current time falls within any of the timing periods, the system enters work status. During the scheduled work hours, the display shows an automatic status. Outside of work hours, the system is in off-hours status. Each timing period includes an on-time (hour, minute) and an off-time (hour, minute), and the operation can set or modify the hours, minutes, and current time for up to three control periods. Different periods allow for different temperature ranges to be set. Fault Records - When a fault occurs, the system displays real-time alarm information and logs the cause and time of the fault. The controller can record up to 5 occurrences of faults for reference.

Password protection is available to set a password for the controller manually, preventing others from arbitrarily setting operating parameters and causing abnormal operation. Users can choose to enable (Password Protection Active) or disable (Password Protection Inactive) password protection. 2. Some models are factory-assembled with most auxiliary parts, reducing much of the hassle during installation. 3. Control System - An intelligent digital product that requires only a few button presses to perform all operations with a simple finger movement. 4. Comprehensive Protection - Boilers are equipped with a high-pressure safety连锁 protection device, controller alarms, burner movement stops, automatic drain opens, and safety valves are activated. 5. Easy Maintenance - Boilers are fitted with hand (head) holes, allowing for convenient internal cleaning and maintenance when necessary. 6. Safe and Reliable - All steam boilers undergo a rated load ignition test upon factory shipment, ensuring the reliability of the boiler performance, combustion equipment, automatic control equipment, and related safety devices through rigorous testing.
