The gas-fired steam boiler adopts a horizontal standard three-return structure, and the combustion method adopts micro-positive pressure combustion. The body of the WNS3-1.25-YQ gas boiler consists of a drum, a furnace (waveform furnace) and two return smoke pipes. The boiler drum is equipped with a steam-water separation device and a water supply device, and the lower part is equipped with a regular sewage device.
When the gas steam boiler is in operation, the fuel is mixed with air in the burner and then ignited by the electronic ignition rod, and then sprayed into the furnace for combustion. The high-temperature flue gas enters the two-stage convection tube bundle from the furnace, and is discharged to the atmosphere from the rear smoke box through the chimney. The structure form is shown in the general drawing and the boiler body drawing. The basic structural components of the gas boiler body are: the cylinder with the shell Φ1800×12, the front tube sheet Φ1800×14, the rear tube sheet Φ1800×14, the corrugated furnace duct Φ600×10, the back The cylinder of the combustion chamber is Φ1200×16, the front tube sheet of the combustion chamber is Φ1200×12, the rear tube sheet of the combustion chamber is Φ1200×12, the tie rod is made of Φ32 round steel, and the smoke pipe is made of 72 Φ51×3 long threaded pipes and 93 long threaded pipes. Φ51×3 short threaded pipe, the boiler combustion adopts a fully automatic combustion system.
WNS3-1.25-YQ gas boiler has a standby function when the steam pressure is higher and a self-start function when the pressure is low. It has the function of automatically shutting down the boiler with high water level and pre-draining water when it is restarted. It has the functions of automatic start-stop setting, time correction, timing start-stop and various priority start-stop and working day, rest day preset, rest day automatic judgment and other functions.
This series of steam boilers have the functions of automatic flame proportional adjustment, automatic furnace purging and automatic detection of flame, wind pressure and oil return pressure. In addition, the steam boiler also has the functions of continuous automatic water supply, automatic control of surface sewage and automatic detection of water level low and high limits. Using touch-type as control programming, it can display the operation status of fans, water pumps, oil pumps, etc. and the state of flame stepless change at any time. It has a full range of online help, and the operation is simple and suitable for people of any cultural level.
WNS series boilers are designed with high-quality brand burners, valve accessories, etc. are preferably imported or domestic high-quality products. The boiler can implement automatic adjustment of load, pressure and water level, and has multiple automatic protection functions such as water shortage, overpressure, flameout, and temperature control against dry burning. Has a high degree of safety and reliability. This product is debugged and passed the factory, it is the ideal heating equipment for industrial and mining enterprises, service industry and other users. We will strive to provide first-class after-sales service to ensure safe and economical use by users.
The front and rear smoke tube boxes of WNS3-1.25-YQ gas boiler adopt multi-stage sealing method, which is convenient for smoke box maintenance. This type of steam boiler adopts a horizontal structure, with ample heating area, sufficient heat transfer, stable operation of the boiler under load changes, and high combustion efficiency.
