Product details
Product Introduction
The WNS series fully automatic methanol (alcohol based fuel) steam boiler (utility model patent) adopts a horizontal three return wet back structure to improve the operating environment of the boiler, enhance boiler efficiency and service life; All smoke channels are placed in water, and the tail is equipped with a waste heat water tank and a complete insulation outsourcing design. The smoke box seal adopts a labyrinth structure to avoid smoke leakage. The boiler has a thermal efficiency of over 90%, using a combination of corrugated and conical furnace liners with good expansion performance. The size of the furnace liner matches the flame, and the flow area of the flue gas is reduced accordingly, ensuring that the flue gas flows at a constant speed and ensuring the heat exchange time of high-temperature flue gas in the furnace, achieving the best heat transfer effect; Adopting high-performance combustion engines that are perfectly matched with the boiler for comprehensive automatic adjustment, ensuring sufficient combustion, saving fuel, and reducing pollution; Using ultra-fine glass wool with high insulation performance, resulting in less heat loss; Adopting an intelligent energy-saving control system to control the boiler and steam (water) supply system, and adjusting fuel supply according to different loads for greater energy efficiency. The installation method is an integral quick installation boiler with minimal vibration and no special requirements for the foundation. It does not require anchor bolts for fixation and is easy to install. Adopting an active furnace head structure, it can match various burners, replace furnace heads, and repair furnace bodies conveniently and quickly. The front and rear smoke boxes adopt a movable and detachable structure, which makes it easy to inspect, maintain, and upkeep the interior of the boiler. It is simple and convenient, with a novel product design, reasonable structure, and good process performance, making this product have outstanding quality. It is the latest developed new product.
Performance advantages
1. Four way boiler patented product
Horizontal internal combustion triple pass fully wet back design, 100% corrugated furnace chamber, with good thermal expansion and contraction, water-cooled combustion chamber, and the combustion chamber is connected to the rear tube plate edge, with the lowest stress and more reliable quality.
2. Large diameter corrugated furnace liner
The boiler combustion chamber is composed of a large diameter full corrugated furnace liner, with a large combustion space, complete fuel combustion, effective heat absorption and thermal expansion, and a large radiation heating surface.
3. Adequate heat supply
The heating area of the boiler is designed and configured to be greater than 25 square meters per ton, fully absorbing effective heat, with low exhaust gas temperature and low heat loss, ensuring sufficient output and high efficiency.
4. Steam quality
The diameter of the pot shell is large, the water capacity is large, the adaptability to load changes is strong, the output is stable, the steam space volume is large, the net distance between the steam water interface and the steam outlet is high, and the steam humidity is low.
5. Multi functional safety explosion-proof device
There is an explosion-proof device connected to the furnace on the back plate of the boiler, which prevents the release of high energy in the event of violent combustion of fuel in the furnace. It can automatically reset and has the function of a fire observation mirror and maintenance channel. By adjusting the combustion flame during operation, the furnace can be inspected and maintained conveniently.
6. Adequate time for safe precipitation
The combustion chamber of the boiler is arranged in accordance with national regulations, and the water level is determined in strict accordance with the international standard for water level fluctuation time. It has sufficient safe precipitation space to ensure the safe operation of the boiler.
7. Convenient boiler maintenance
The top of the boiler is equipped with a manhole, and the front and rear parts of the boiler are equipped with hand hole devices for easy inspection and cleaning of the equipment inside the boiler and the bottom of the boiler.
8. Unique sealing of front and rear smoke boxes
The smoke box adopts a double opening smoke box door, which is easy to open and has a multi-stage labyrinth seal. The sealing material is specially made, with good compression performance, completely blocking the leakage of smoke, and can be reused.
9. Reliable pressure and water level protection
Multiple control protections are set for boiler pressure and water level, as well as over smoke temperature protection, to ensure the safe operation of the boiler.
10. Leading in automatic control level
The boiler controller adopts Siemens and Delixi electrical components, with reliable performance. Chinese and English menu type with LCD screen display, touch screen type for remote control of human-machine dialogue.
