Product Description
Product Description
This is a coal-fired horizontal double-drum steam boiler. Simply, I consist of steam drum, water drum, convection tubes, insulation lay, steel coat, coal feeder, chain grate furnace and so on.
1. Boiler Feature
- After simplifying the water-cycle route, we can reduce the water-cycle resistance, raise ascending tube velocity, improve the stability of the water cycle and ensure a safe and stable operation.
- Design enough heating surface, which makes more heat from fuel absorbed. Flue smoke temperature can be lower than 170ºC.
- Reasonably design front and back arch to improve the temperature in the furnace. We also strengthen the disturbance of smoke in the high temperature area. These reduce heat lose and fly ash loss as a result of incomplete combustion.
- We adopt light chain grate and independent air chamber. We strengthen the seal airtight of the two sides of chain grates. These make the fuel burn fast and fully.
- Our boiler 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 these designs make our boilers obtain a higher heat efficiency than normal, up to 81%.
- 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 1800 mg/Nm3. Our high efficiency dust collector makes sure the dust removal efficiency up t0 90%, SOX and NOX removal efficiency up to 98%. These measures can meet the global demands and standards of environmental protection.
- Compact structures are designed, except the 4t/h and 6t/h packaged steam boiler. That can save boiler house and reduce the installation workload and time.
- We enlarge the diameter of steam drum to supply a big space of water-steam separation device. So that we can offer steam in good quality.
- High automatization, safe and easy operation. In the electrical control cabinet, we design automatic feeding water, alarm and safety interlock of high/low water level, air blower and draft fan.
2. Control and safety systems
The control and safety systems are interlocked in an electric control cabinet.
- Sound-light alarm of high and super-high steam pressure;
- Sound-light alarm of high and lowe water limit level;
- Sound-light alarm of pressure loss in the water pumps;
- More safety devices are designed and connected with the electric control cabinet (ECC). More details will be explained in the ECC Manual.

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.
