New Type Industrial Use Natural Gas Fired Steam Boiler
Technical features of WNS boiler
The WNS boiler produced by ZG boiler is a oil and gas boiler, which can be divided into WNS oil and gas hot water boilers and WNS oil and gas steam boilers, and is also a well-developed hot boiler by ZG boiler. The technical features of this boiler are as follows:
1. The WNS oil and gas boiler adopts a large-volume combustion chamber design, so that the fuel is fully burned and the flame fullness is good. Good for low-nitrogen combustion of fuels and low nitrogen emissions from flue gas.
2. The WNS oil and gas boiler uses an automatic low nitrogen burner + flue gas recirculation system (FGR) system to achieve ultra-low nitrogen emissions.
3. The WNS oil and gas boiler adopt advanced wave furnace structure, which not only increases the heat transfer area, but also satisfies the free expansion of the furnace after heating. At the same time, the waveform furnace structure enhances the disturbance of the flue gas and enhances heat transfer and combustion.
4. The rear of the boiler body is equipped with an energy saver and a condenser, which can effectively reduce the temperature of the exhaust gas and improve the overall thermal efficiency of the boiler. The condenser adopts "low temperature corrosion resistant" special steel to greatly increase the service life.
5. The oil and gas boiler adopts a wet-back structure and full-flanged butt welds with high reliability and low maintenance costs.
6. The use of threaded tobacco pipes in the WNS oil and gas boiler is beneficial to enhance airflow disturbance and enhance heat transfer.
7. The WNS oil and gas boiler outer packaging adopts color pattern board, mirror stainless steel or matt stainless steel board in three forms, beautiful and generous.
8. Automatic operation of the WNS oil and gas boiler, micro-positive pressure combustion, no need to draw fan, reduce boiler system investment, reduce boiler operating costs.
9. The WNS oil and gas boiler equipped with necessary thermal instruments, valves and various protection devices, to achieve continuous electric water regulation, automatic water level control and high and low water level alarm, low water level chain protection and other functions, automatic control of steam pressure and overpressure alarm and other functions.
Fast boiler is a research and development, production and sales of high-tech enterprises, adhering to the "do professional, responsible for cleaning boiler systems integration provider" business philosophy, creating a series of excellent quality boiler equipment, such as WNS series gas (oil) boiler, SZS series of gas (oil) boilers, electric boilers and so on; second to none in the area of the National clean boiler. But we never had stalled the pace of independent research in recent years, the introduction of movable type boiler, after obtaining a favorable investment market.
Select new type industrial use fired steam boiler fuel gas of good or good? Steam boiler has a lot of varieties, the most common classification is based on it can be divided into fuel to burn natural gas and electricity and fuel burn of. When buying a steam boiler, a lot of people do not know that we should buy natural gas or fuel steam boiler steam boiler. Gas boilers and oil boilers are our two most common ways the boiler. If you want to use natural gas steam boiler, the need to ensure that there are local gas can be switched on; if you want to use oil-fired boiler, the procurement needs daily oil tank and oil tank buried, placed in position and good design, so that the fuel supply to the boiler. Gas-fired boiler burning natural gas, it has the primary energy saving, high thermal efficiency strengths, oil-fired boiler burning diesel fuel is light, it has a simple fuel reserves by the fuel supplier strengths affect small. The primary operating costs and fuel gas steam boiler steam boiler related with local energy pricing. Per ton of steam vapor is about to use the side 80, if the offer by gas 3 yuan / square to count, that is, 240 / ton operating costs. Steam per ton of about 66kg of light diesel oil is used, if the press 9 yuan / kg fuel offer calculated, then the cost of steam is about 594 yuan / ton. To compare quotes from the fuel, then, natural gas will be cheaper than oil.

Talk about the overall structure of the furnace boiler boiler boiler and auxiliary equipment, including two parts. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Today, we are concerned that the furnace boiler. Also known as boiler furnace combustion chamber, fuel combustion for space. It solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as the fire-bed furnace. Solid fuel liquid, gas or pulverized, is injected into the furnace fire chamber may be referred to as a combustion chamber of the burner, also known as the furnace fire chamber. The coal particles and air hold it was boiling point of combustion, the furnace and adapted called inferior fuel combustion fluidized bed furnace, known as a fluidized bed furnace. An air flow so that the coal particles rotated at high speed, and strong burning furnace called cylindrical cyclone furnace. Boiler furnace cross-section is generally square or rectangular. Combustion fuel to form a flame in the furnace and high temperature flue gas, so the hearth around the furnace wall is made of refractory material and insulation material. On the inner surface of the wall of the furnace waterwall tubes often laid, it will not burn both protect the furnace wall, and absorb a large amount of radiation heat of the flame and the high temperature flue gas. In addition, the furnace design needs to fully consider the characteristics of the fuel used. Each boiler should be fueled with the original design of the fuel. Boilers running economy and reliability are likely to vary greatly reduced when using the characteristics of fuel combustion.
