WNS Series Oil/Gas Fired Steam Boiler

Product Overview

The WNS series oil/gas steam boiler is a horizontal quick-install internal combustion three-pass fire tube boiler. It adopts an offset furnace wet-back structure. The high-temperature flue gas successively flushes the second and third pass smoke tubes, then discharges into the atmosphere through the rear smoke chamber and chimney. The boiler has sufficient thermal power: the heating surface is configured according to high standards to fully absorb effective heat, resulting in low exhaust gas temperature, small heat loss, ensuring sufficient output and high efficiency. The boiler is equipped with movable front and rear smoke box covers, making maintenance convenient. The WNS series boiler is equipped with industrial burners with good technical performance, adopting advanced technologies such as automatic proportional combustion adjustment, automatic water supply adjustment, program start/stop, and fully automatic operation. It also has automatic protection functions such as high and low water level alarms, low water level, ultra-high steam pressure, and flameout protection. This type of boiler is characterized by compact structure, safety and reliability, simple operation, quick installation, less pollution, low noise, and high efficiency. It holds a new type patent certificate, Utility Model Name: A Horizontal Oil-fired Steam Boiler; Patent No.: ZL 2014 2 0504448.2. The WNS series oil/gas steam boiler is suitable for the chemical industry: fertilizer plants, oil refineries, beverage plants, coating plants, plastic plants, glass plants, sulfuric acid plants, etc.; manufacturing industry: paper mills, textile mills, dairy plants, wineries, food factories, edible fungus workshops, shoe factories, ceramic factories, furniture factories, tire factories, mat factories, cigarette factories, chopstick factories, printing plants, tape factories, foam factories, hardware factories, flooring factories, cabinet factories, door factories, battery factories, salt factories, tea factories, instrument factories, etc.; construction industry: road and bridge maintenance, concrete steam curing, aerated brick steam curing, etc.; as well as agricultural product processing, pharmaceutical production, fireproof material production and other industries.

Key Features

• Large Diameter Corrugated Furnace: Composed of a large-diameter full corrugated furnace, providing a large combustion space for complete fuel combustion, effective absorption of thermal expansion, and a large radiant heating surface.
• High Steam Quality: Large boiler shell diameter and water capacity ensure strong adaptability to load changes and stable output. Large steam space volume provides sufficient height between the steam-water interface and the steam outlet, resulting in low steam humidity.
• Sufficient Safety Water-Drop Time: The combustion chamber is positioned low, and the water level is determined in accordance with national regulations and strict international standards for water level fluctuation time, providing ample safe water-drop space to ensure boiler operation safety.
• Multi-functional Safety Explosion-proof Device: An explosion-proof device connected to the furnace is installed on the boiler rear panel. It prevents high energy generated instantly during violent deflagration in the furnace from causing damage, can reset automatically, and also serves as a flame observation sight glass and inspection channel, facilitating furnace inspection and maintenance during operation.
• Convenient Internal Inspection: Manholes are provided at the top of the boiler, and handholes/manhole devices are provided at the lower middle parts of the front and rear ends, facilitating maintenance and cleaning of internal devices and the boiler bottom.
• Unique Front and Rear Smoke Box Sealing: The smoke box adopts double-opening doors for easy opening. It uses multi-stage labyrinth sealing with special sealing materials, providing good compressibility to block flue gas leakage, and can be reused.
• Reliable Pressure and Water Level Protection: Multiple control protections are set for boiler pressure and water level, as well as over-smoke temperature protection, ensuring the safety of boiler operation.
• High Level of Automatic Control: The boiler controller uses Siemens or Delixi electrical components with reliable performance. Three forms of controllers: standard type, LCD menu type with Chinese/English display, and touch screen type with human-machine dialogue remote control.
