6t Szl Horizontal Coal-Fired Steam Boiler

1. Product features1. After simplifying the water-cycle route,reduce water-cycle resistance,
Raise ascending tube velocity, improve the reliability of the water cycle and ensure a safe and stable operation.2. Design enough heating surface, which makes more heat from fuel absorbed. Flue gas temperature is about 170° C.3. Reasonable designing front and back arch to improve the temperature in the furnace, we also strengthen the disturbance of smoke in the high-temperature region. That reduces heat loss and fly-ash loss as a result of incomplete combustion.4. We adopt light chain grate. It is easy to operate and convenient to maintain. Effective area of grate is up to 8.08 m2. That makes sure that the fuel is burned fully.5. Our boilers have a large convection heating surface, a stable performance and
even a long time overload work. What's more, we design the convection tube bundles in alternate permutation instead of in-line arrangement. All of those make our boilers can absolutely have a high heat efficiency.6. Through taking above measures, thermal efficiency of each specification boiler is more than 78%, and is higher than national standard.7. We design double side air inlet and independent air plenum. And at the exit of furnace we set up a smoke separation device by inertia, which makes the original discharging dust concentration lower than 1800mg/Nm3. Our efficient water film dust scrubbing dust collector makes sure the dust removal efficiency up to 90% and SOx and NOx removal efficiency up to 98%. These measures can meet all the demands and standards of environmental protection in the world.8. Compact structure (except the 4t/h steam boiler, the others are assembled at site). We design a compact structure, which can reduce the installation workload at site and shorten 2/3 of installation period.9. We enlarge the diameter of steam drum to improve the water-steam separation device. So that we can ensure the steam of good quality.10. High automatization and easy operation. With our home-made ECC, we can achieve automatic feeding water, alarm and safety interlock of water level, safety interlock of air blower and induced draft fan, etc.3. Service terms
