WNS type fuel oil (gas) boiler is a horizontal quick-loadinginternal combustion three-return fire-tube boiler, which adoptsthe bile wet back structure of the bias furnace,and thehigh-temperature flue gas washes the second and third returnsmoke pipes in turn, and then discharged into the atmospherethrough the chimney from the rear smoke chamber. The boiler isequipped with movable front and rear smoke box covers, whichmakes the boiler easy to maintain. The boiler is equipped with aburner with good technical performance,adopts advancedtechnologies such as automatic proportional adjustment ofcombustion, automatic adjustment of feed water, program startand stop，automatic operation, etc., and has automaticprotection functions such as high and low water level alarm andextremely low water level, ultra-high steam pressure，andflameout. This type of boiler has the characteristics of compactstructure， safety and reliability， simple operation, rapidinstallation, less pollution, low noise and high efficiency.

Key Features：

1. The overall structure is reasonable and compact, in line with thefactory conditions of quick installation, this product is composed of three partswhen leaving the factory; Boiler host, chimney and pipeline system, of whichthe main engine and chimney part have been manufactured in the factory, thepipeline valves and instruments supporting the main engine have beenrandomly installed, and transported to the site to assemble the main engineand chimney. The on-site connection of air source, power supply, waterpipeline can be commissioned, which greatly shortens the installation periodand can ensure product quality.

2. Advanced design performance, the boiler host belongs to the overallstructure, the burner is assembled on the front smoke box cover, the body ismainly arranged heating surface and combustion chamber part, withreasonable structure, compact, low steel consumption, the furnace bladderadopts offset wave bladder, the insulation layer adopts new lightweight thermainsulation material, the outer packaging adopts color sheet, and the shape ispacked as a cuboid, so that the boiler performance, weight, structural size.appearance shape and domestic products of the same capacity have obviousadvanced and aesthetic sense. The boiler feed water equipment is configureoon the boiler base on the right side of the boiler to make it integrated with themain engine, without the need for another foundation.

3、The water circulation is simple, the structure of the pressurized partsis reasonable, and it can be operated safely under the condition of ensuringwater quality.

4、Complete supporting auxiliary machines,advanced comprehensive technical performance.

The main advantages of oil-fired (gas) boilers

1.Safe operation, stable performance and sufficient output.

2. Clean energy is adopted, in line with national environmentalprotection policies, and the boiler room is clean and pollution-free.

3. Fully automatic operation, when gas, water and electricity are innormal state, it can be in order Automatic opening of the boiler system,less stoker labor.

4. The boiler occupies a small area and saves infrastructure investment.

5. The boiler starts quickly, and it can reach the rated working state in20 minutes.

6. The combustion device adopts imported original products, which hassuperior performance and low maintenance costs.

7. The boiler adopts 100mm insulation layer, and the outer walltemperature does not exceed 50 seven (national standard).

8. The furnace bladder adopts the most advanced waveform bladderstructure in China to increase the heating area of the furnace bladder.

9. The smoke pipe adopts efficiency heat transfer element toimprove the heat transfer coefficient of the smoke pipe.

10. When the steam pressure is greater than the set value, the furnacecan be automatically stopped, and when the water level is less than thesafe water level, lt can automatically stop the furnace and alarm.

11. When the burner fails, the furnace can be stopped and alarmed.
