Industrial Mill Coal Fired Hot Water Boiler / Fire Tube Hot Water Boiler System

Higher efficiency fire tube hot water boiler 0.7-4.2MW with horizontal type for industrial mill

DZL series fire tube hot water boiler adopts horizontal three-return water-fire tube structure, and the burning equipment adopts light chain grate. The fuel is mainly various types of bituminous coal. The boiler body is arranged in a longitudinal direction of a single drum, and a threaded pyrotechnic tube is arranged in the drum to form a convection heating surface, and the drum and the water wall on both sides constitute a furnace heating surface. The whole boiler is shipped in a quick release form. The electric control device can realize the functions of stepless speed regulation of the grate, equipment parameter display, limit parameter alarm and interlock protection. At the same time, it has the characteristics of high power, high thermal efficiency and high degree of automation.

Fire tube hot water boiler features:
1. Reasonably design the structure of the furnace arch, furnace wall and furnace radiant heating surface. At the same time, the boiler adopts high-efficiency heat transfer component-threaded pipe to ensure the combustion efficiency of the boiler.

2. The water-fire tube structure inside the boiler greatly prolongs the service life and solves the defects of the cracking of the traditional boiler tube sheet.

3. Tthe company can be equipped with different combinations of dust removal, desulfurization, denitrification and other equipment according to the requirements of users, effectively reducing the discharge of pollutants.

4. According to the actual needs of customers, can design different control schemes based on DSP/PLC/Blower frequency conversion control, to maximize the investment for users and reduce the operating cost of equipment.

5. In the fire tube hot water boiler production process, in the important processes, such as coiling, cutting, drilling, etc., all CNC machining equipment is used to ensure the processing accuracy and improve the reliability of the boiler.

6. The coal-fired hot water boiler is fully automated in the operations of fuel injection and slag removal, which improves the efficiency of the equipment.

7. All auxiliary equipment must undergo strict tests before leaving the factory to ensure stable running time.

8. According to the needs of users, the company can carry out customized production, such as designing the exclusive appearance and color.

9. The horizontal coal-fired hot water boiler is of a single-cylinder vertical type in the structure, and the water wall tube is installed on the left and right sides of the furnace, the threaded tobacco pipe is arranged in the drum, and the movable grate with few coal leakage is adopted, and the structure is reasonable and highly thermal efficiency.
