3T/H 3000kg Industrial Natural Gas Oil Fired Steam Boiler for feed pellet line

WNS series oil/gas fired boiler adopts horizontal three-pass wet-back structure,large corrugated furnace and patented thread pipe technology,equipped with international first-level brand burners and valve groups,and independently developed high-matching PLC control system to realize muitiple linkages.The lock protection function protects the equipment running safely.

It is full-automatic oil(gas) fired packaged steam boiler; adopting horizontal internal micro positive pressure combustion, full wetback design, high efficiency spirally corrugated tubes, fuel economizer and reasonable insulation package; the thermal efficiency can reach more than 90%. Its novel design, rational structural and nice performance achieved perfect quality and nice performance.

main features

1. The overall structure is reasonable and compact, belonging to the packaged steam boiler which meets the delivery conditions of quick installation.This steam boiler is composed of three parts when it leaves the factory;The main steam boiler, chimney and piping system, in which the main engine and chimney parts have been manufactured in the factory, and the piping valves and instruments supporting the main boiler have been installed randomly, and then transported to the site to assemble the main engine and 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 products.

2. Advanced design performance.The main boiler is of integral structure, the burner is assembled on the cover of the front smoke box, and the main body is arranged with heating surface and combustor.With reasonable structure, compact, low steel consumption, furnace with offset waveform furnace, thermal insulation layer choose new lightweight heat insulation material, outer packing USES color sheet, appearance packaging for cuboid, the boiler performance, weight, structure size and appearance modelling and compared with the capacity of the domestic product has obvious advancement and the look and feel.The boiler feed water equipment is arranged on the boiler base on the right side of the boiler so that it can be integrated with the main engine without having to make another foundation.

3. Our packaged steam boiler is simple water circulation, reasonable structure of pressurized parts, safe operation under the condition of ensuring water quality.

4. Complete auxiliary equipment and advanced comprehensive technical performance.

This package steam boiler adopts the international advanced high degree of automation of automatic burner "black" as the main combustion equipment, the burner combustion process is controlled by a more advanced burning program controller, can realize the normal fuel boiler combustion required for a variety of functions, can be in normal state, the accident state, in an extraordinary situation, implement protective boiler stop automatically, match with corresponding proportion of water level controller, pressure regulator, high and low water level indicator, overpressure, adjusting, guarantee the water level fluctuations within the normal range, the steam pressure within the scope of the allowed pressure fluctuations, the water level is very low,Implement protective stop indication when overpressure.

Executive Standard

1. Design, manufacture, assembly, experiment and acceptance of boilers in strict accordance with national and industrial standards, including but not limited to the following standards: GB/T16508 Boiler Shell Boiler, TSG G0001 Boiler Safety Design Supervision Code, GB50273 Boiler Installation Engineering Construction and Acceptance Code

2. The main steel used in the boiler is 20 GB/T3087, which ensures the safety and reliability of the boiler.

3. Welding materials shall be selected according to NB/T47018. Full penetration welding with argon protection shall be performed on the boiler tube.
