WNS series steam boiler can run stably under 80%-100% working conditions. In the case of 100% rated load, the boiler operating parameters are: feed water temperature of 20℃, pressure of 1.0MPa, 1 ton of water steam of 184℃ can be produced within 1 hour, the calculated thermal efficiency is 98.19%, and the exhaust temperature is 57℃. Fuel consumption is 70.34Nm3 /h (the low calorific value of natural gas used in this product is ≥35438KJ/ Nm3).
WNS series boiler is a kind of horizontal internal combustion three return gas quick loading boiler, using the center back combustion structure. It is composed of a wave furnace and a smoke pipe. The boiler is equipped with perfect automatic control device and safety protection device, to realize automatic control of water level and the lowest water level alarm, stop furnace; Boiler automatic ignition, burner fire automatic regulation and flameout protection to ensure the safe operation of the boiler.
When the product is running, the fuel is ejected from the burner, ignited by the electronic ignition stick, and the combustion is carried out under small positive pressure in the furnace. The high temperature flue gas rotates 180° in the furnace to enter the front flue gas box, and turns 180° from the front flue gas box to enter the threaded flue gas tube bundle. After full heat transfer in the tube bundle, the flue gas enters the rear flue tank, and after gathering in the rear flue tank, it enters the chimney and is discharged into the atmosphere.
WNS series steam boiler is mainly composed of pressure body, base, packaging and heat preservation, instrument valves and accessories, front smoke box, after smoke box and electric control system and other parts. Boiler body in the overall structure of the bottom of the furnace, smoke pipe symmetrical arrangement of the form, cylinder by Ф1608×12 cylinder and DN1600×16 before and after tube plate welded into the return for the furnace, furnace structure size is 820×10. The boiler combustion using the form of central back combustion, furnace heat exchange efficiency is high, the overall structure of the boiler is compact; The second return is composed of 59 Ф51 threaded smoke pipes. The flue gas in the threaded pipe has strong disturbance, which can effectively improve the heat transfer capacity of the pipe.
The series of steam boiler before and after the smoke box adopts the integral structure, smoke box has a pair of open smoke box door, the form of good integrity, beautiful, generous, easy to open during maintenance, sealing is also very good. The boiler is equipped with A48H-1.6C spring fully open safety valve (DN50) two pieces, A47H-1.6C spring micro-open safety valve (DN40) one piece. At the same time equipped with water level gauge, water level control alarm, water supply electric regulating valve, but also equipped with ordinary pressure gauge, electric contact pressure gauge, can effectively monitor and control the water level and pressure. Flowmeters are installed in gas and water supply pipelines, and bimetallic thermometers are installed at the tail of the flue, which can fully meet the requirements of monitoring and control.
Our factory is specialized in producing and manufacturing various types of boiler products. The boiler burner adopts foreign imported gas burner with high automation degree. It can realize automatic control from pre-purge, ignition, automatic conversion of fire power to automatic stop and flameout protection. WNS series steam boiler installation quickly, less pollution, low noise, high efficiency. Mainly used in food processing, printing and dyeing, pharmaceutical production steam, medical institutions to provide disinfection steam, for other enterprises, hotels to provide steam heating, can also provide domestic hot water through the water tank heating.
