Product Specification

250hp 3ton 3000kg Industrial Oil Gas Fired Packaged Steam Boiler for Steam Sterilizer Autoclave

1. Boiler system

WNS series oil and gas steam boiler adopts shell type full wet back type fire tube structure. The structure adopts three return journeys, in which the oil or gas is well atomized by the burner and fully mixed with the air, and is completely burned in the corrugated furnace bile, and then turns from the rear smoke chamber into the return smoke pipe, turns to the front smoke box into the return smoke pipe, enters the back smoke box, and is discharged by the chimney.The size of the furnace liner we choose is large, which provides conditions for the full combustion of fuel, so this packaged steam boiler can burn heavy oil, light oil, natural gas and city gas. In addition, our company adopts threaded smoke pipe in the design, and the relative flow rate can control low smoke resistance, low power consumption and large load regulation ratio under the guarantee of sufficient heat transfer.

When industrial steam boiler goes out of the factory, it is composed of three parts: the main boiler, the chimney and the pipeline system. The main body and the chimney have been manufactured in the factory, and the supporting pipeline valves and instruments of the main boiler have been installed randomly, and then transported to the site to assemble the main body and the chimney.On the spot connect the air source, power supply and water pipeline to start the test.Greatly shorten the installation cycle, and can guarantee the quality of boiler.

Free-Installation

Before the shipment, complete boiler system is well skid-mounted on the basement, also we have done the pipe(valves) connection and wire connection. After receiving the boiler, no need installation/ assembly. Just join the boiler to water/ gas/ electricity. Comparing with other traditional boilers in the market, our boiler does save lots of cost/ energy/ time in installation. The additional, the entire boiler system is portable.

3. Performance advantage

1. Boiler design

Horizontal internal combustion three return journey full wet back design, 100% corrugated furnace, with good thermal retrability, water cooled retrorse chamber, retrorse chamber and back tubeplate butt joint, lowest stress, more reliable quality.

2, large diameter corrugated furnace

The boiler combustion chamber is composed of a large diameter full ripple furnace with large combustion space, complete fuel combustion, effective heat absorption and thermal expansion, and large radiation heating surface.

3. Sufficient heat

The heating area of the boiler is designed to be more than 25 square meters/ton, fully absorbing effective heat, low smoke exhaust temperature, small heat loss, ensuring sufficient output and high efficiency.

4. Steam quality

Pot shell diameter, large water capacity, strong adaptability to load changes, stable output, steam space volume, soda interface and steam outlet net distance is high, low steam humidity.

5. Multi-functional safety and explosion protection device

The back plate of the boiler is equipped with the explosion-proof device which is connected with the furnace to prevent the high energy of the discharge moment when the fuel is violently deflated in the furnace, and it can automatically reset. Meanwhile, it has the function of the fire-viewing mirror and the maintenance channel. It makes use of the adjustment of the burning flame in operation, and makes the furnace inspection and maintenance convenient.

6. Safe precipitation time is sufficient

The combustion chamber of the boiler is arranged and the water level is determined in accordance with the national regulations. At the same time, it is strictly in accordance with the time requirements of the water level fluctuation standard of the international general norms. It has sufficient safe precipitation space to ensure the operation safety of the boiler.
