The heat efficiency of the boiler is 6-8% higher than that of the national professional standard by using a high-efficiency heat transfer element, a spiral flue gas pipe, and a reasonable flue gas flow rate
2. Convex tube sheet and screw discharge pipe make the shell change from quasi rigid body to quasi elastic body. With the help of airfoil flue, the defect of cracking of high temperature tube sheet of traditional pyrotechnic tube boiler is completely avoided.
3. Reasonable water circulation circuit and unique backwater injection device (hot water boiler) can improve the water velocity of riser and avoid the tube explosion of water wall.
4. The inertia separation of the dust in the furnace and the high-efficiency multi tube dust collector are used to make the dust concentration of the boiler meet the requirements of the first class area. The reasonable boiler structure can support itself without steel frame
5. Energy saving and strong radiation furnace arch can ensure the stable combustion of bituminous coal or anthracite
High standard and high quality auxiliary equipment, accessories and automatic control equipment are adopted to ensure the safe and stable operation of the boiler and reduce the labor intensity of the stoker
7 compact structure, 1-20h (0.7-14wm) boiler can be arranged in a single layer.
