1. Technical description
SZL series steam boiler is a kind of horizontal, double drum, water tube, chain grate boiler. There are two drums up and down: Steam drum and water drum. The front of steam drum and two-side water tubes walls compose the radiation heating area. The convection tube bundles between the back of steam drum and the whole water drum compose the convection heating area. The economizer is arranged at the back of the boiler. In the economizer, the sofe water is heated by the hot smoke, then the hot soft water goes into the steam drum. It makes use of the hot smoke's heat and saves more fuel. The steam comes out of boiler to go into the steam distributor, which will distribute the steam for different equipments. There are two kinds of cyclones for your choice: Multi-tubular cyclone and water-film cyclone. The dust removal efficiency of both cyclons is up to 95%, while the SOx and NOx removal efficiency is up to 98% for the second one.
2. Product features
After simplifying the water-cycle route, we can reduce the 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. Reasonably 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.

Oil-fuel/Gas-fuel horizontal organic heat-carrier boiler
YY(Q)W horizontal oil(gas)-fuel boiler is a kind of forced circulation oil(gas)-fuel organic heat-carrier boiler. The heating surface of this series of boiler is compact. The heating surface consists of inner, (middle) outside disc tubes. The inner ones will be radiantly heated while the middle and the outside ones will form the convection heating surface. The fuel will be burnt in the combustor formed by the disc tubes. And the most heat will be absorbed by the radiant heating surface, then the air of high temperature will enter the convection heating surface to exchange heat. At last, the air and smoke of low temperature will be
Discharged directly to the atmosphere through the chimney.
Features:
1. The heat efficiency is high and the structure is special. The general heat efficiency can reach up to 90%.
2. The horizontal design is easy and convenient to operate.
3. With the disc tubes, the heating surface can be heated fully and the heat load of the tube can be lowered.
This makes the conductive oil safer.
4. The size of the hearth matches the flame. The heat exchange rate is rather high.
5. The control system is accurate and the temperature of the conductive oil can be controlled within ± 1º C.
6. We have the interlock and other feedbacks if there's any emergency.
