This series of products utilizes a double-drum offset furnace chamber structure, featuring high technology content and environmental protection with energy-saving.After simplifying the water circulation loop, the resistance of the water circulation was reduced, increasing the flow rate inside the riser tubes. This is particularly beneficial for adding return water injection devices to the left and right water-cooled walls of hot water boilers where the resistance in water circulation flow is high. It enhances the reliability of the water circulation, ensuring the safe and stable operation of the boiler.
Arrange sufficient heating surfaces to ensure that the heat released by the fuel combustion is fully absorbed by the heating surfaces and then transferred to the working medium. The exhaust temperature is generally around 160°C.
Properly arrange the front and rear arches to increase the furnace temperature, while reducing the heat loss from incomplete combustion and fly ash due to the disturbance of flue gas in the high-temperature zone. Large heating surface, rapid pressure increase, sufficient output, quick temperature rise, and low energy consumption.
Utilizing large, loose-core grate pieces and ensuring ample grate area, this design enhances the reliability of the grate operation while ensuring complete combustion of coal. The large furnace chamber volume and strong coal adaptability allow for the use of various materials as fuel.
The heat exchanger tubes are rearranged from straight to staggered, enhancing heat transfer efficiency by increasing the heat transfer coefficient, thereby improving the boiler's thermal efficiency.
By implementing the above measures, the thermal efficiency of all boiler models exceeds 76%, surpassing the standard requirements.
Dual-side air intake with independent air chambers and adjustable settings ensures stable combustion and reliable operation. A dust inertia separator is installed at the furnace outlet, reducing the initial dust emission concentration to below 1800 mg/Nm³. Combined with an efficient multi-tube dust collector, the furnace is designed with a cyclone combustion chamber structure. The high-temperature flue gas is spun at high speed, achieving mixed combustion and dust separation, thereby achieving first-stage dust removal, energy saving, and environmental protection within the furnace.
Compact structure, 2t/h to 6t/h (1.4MW to 4.2MW) all quick-assembly models available for factory delivery, short installation period, and low investment. The above-boiler diameter increase expands the steam space while improving the steam-water separation.
