10 Ton Steam Boiler SZL10-1.25-AII steam boiler manufacturer

SZL10-1.25-AII is a horizontal double-drums, vertical membrane wall 10 Ton Steam Boiler. Coal or biomass particles get in the chain grate stoker from the front, then into the chain furnace row. After the combustion is completed, the boiler slag machine discharges them at the end.

What Is The Design Of 10 Ton Steam Boiler?

Fresh air from the blower enters to chain grate stoker air chamber partition through the air ducts on both sides of the grate base and enters the furnace through the fuel layer.

Hot flue gas after fuel combustion passes through the furnace, combustion chamber,  convection tube bundle I,  convection tube bundle II, and the economizer. Then it exits the boiler, passes through the dust collector, and is exhausted into the atmosphere by the induced draft fan to the chimney.


Furnace front walls are arranged on both sides of the wall radiation heating surface. A front header leads 15 roots φ51 is × 3 rises water wall tubes front fence. Each lead from both sides of title 100 root φ51 is × 3 rises spacer water wall tubes.

The secondary air ducts are arranged under the front arch, the left, and right sidewalls, and the secondary air converges into a tangential circle in the middle of the furnace.

Between the upper pine and the flower pot, we arrange two pairs of flow tube buttons. Size is φ 51 × 3mm, 20 # seamless pipes no.20 boiler. These tube bundles are arranged in series, with a horizontal pitch S 1 =120mm and a longitudinal section. Distance S 2 =85mm, 18 rows in the horizontal direction, 21 rows in the vertical direction and 14 rows in the vertical direction.

A cast-iron economizer is arranged in the boiler, which can further reduce the exhaust gas temperature of the boiler. The flue gas temperature at the economizer outlet is lower than 170 ℃, and the economizer tube length is 1500mm.

What Is The 10 Ton Steam Boiler Pros?

 1. SZL10 – 1.25 – AII 10 Ton Steam Boiler has an efficient design that occupies a small volume. You can control civil construction investment in a very reasonable range.

2. The chain furnace row is configured with a separate wind chamber equipped with a sticker. The amount of air can be adjusted according to the combustion situation so that the hint is the best flame effect, promoting the combustion of coal and biomass particles.


3. Design different fresher according to other fuel characteristics. For example, the coal-fired furnace is low and can extend, and the biomass boiler uses a shorter furnace, a higher furnace, to promote effective fuel combustion.

4. To facilitate transportation, our factory can produce boilers into two parts, easy to install and move. After the boiler reaches your designated location, you can install it after assembling two parts of the host. Then, pour the upper and lower stove wall, install the slag machine, blower, air blower, flue gas, and other auxiliary systems, boilers can operate.

5. The water wall tubes of this boiler are arranged tightly to effectively reduce the temperature of the furnace walls on both sides. Therefore, the furnace wall behind the water walls on both sides can be lightweight, which can effectively reduce the transportation weight and have the characteristics of fast start-up and rapid-fire-up.

Brief introduction of boiler operating conditions:

Our product design fully complies with TSG G0001-2012 “Boiler Safety Technical Supervision Regulations” and TSG G0002-2010 “Boiler Energy-saving Technical Supervision and Management Regulations”.

10 Ton steam boiler can operate stably under 70% -100% working conditions. Under 100% rated load, the boiler operating parameters are feed water temperature of 20 ° C, boiler rated pressure of 1.25 MPa, and 10 tons of steam at a temperature of 193 ° C.

10 Ton Steam Boiler efficiency is 81.22%, adding air preheater, and theoretical efficiency reaches 84% after the oxygenator. And The Exhaust Gas Temperature IS 155 ° C.

The boiler fuel consumption of the boiler is 2267.4kg / h. You can use fuel type to use Biomass Pellet Fuel, and the coal-fired particles are controlled at 4-30 mm.

 We are one of your best choice of 10 ton steam boiler manufactures.
