Condensing boiler burner manufacturers talk about: the advantages of condensing low nitrogen pressure boiler

Information

Condensing low nitrogen pressure boilers are widely used in major civil and commercial places, such as civil duplex villas and commercial hotels. It is easy to operate, adopts PLC controller, and has high configuration. The operation of the boiler can be controlled by simply touching the buttons on the screen during the whole process, thus greatly reducing the cost of manual supervision after the boiler is used. So what are the advantages of condensing low nitrogen pressure boilers? The following condensing boiler burner manufacturers will take you to find out.

 

One: Long service life: ( 1) Good weather resistance (good antifreeze performance): Condensing low nitrogen pressure boilers can be used in various environments, and can also be used with confidence in northern regions. With antifreeze protection. When the water level in the boiler is lower than the set value, it will automatically run and heat up, and when the water temperature reaches the agreed temperature, it will automatically stop running, so that the equipment itself and its auxiliary equipment can be protected. (2) Good corrosion resistance: The pressure boiler not only has a scientific design and structure, but also optimizes the operation of each system. It can not only prevent low temperature and corrosion, but also avoid the cold shock of the furnace wall, so the pressure boiler has strong durability and a longer service life .

 

Two: Safety in use (over temperature, water shortage alarm): In order to ensure the safe operation of the boiler, the pressure boiler is designed with multiple safety doors. It has an over-temperature alarm function, that is, when the water temperature is too high, it will automatically stop heating and perform an over-temperature alarm. After a complete troubleshooting, just reset it manually; it also has a water shortage protection function, which can automatically stop and sound an alarm when there is a shortage of water to prevent dry burning.

 

Three: High thermal efficiency (full use of energy, good energy saving effect): The domestic professional pressure boiler has a large heating surface and high heat exchange efficiency, which can improve the heat transfer effect to a greater extent. In addition, the outer protective layer of the easy-to-use pressure boiler is effective, and glass wool is used to ensure constant temperature and prevent extensive heat dissipation. Relatively speaking, its heat loss is small, and the energy can be fully utilized to achieve high efficiency and energy saving.

 

The above are the advantages of condensing low nitrogen pressure boilers. To sum up, the pressure boiler has good safety performance and high thermal efficiency, and can meet the safety needs of practical work. Its ergonomic design is powerful, and the digital control system prevents human operator errors and reduces the cost of operator input. Overall, great value for money.

Introduction of low nitrogen burner
Low nitrogen burners and low nitrogen oxide burners refer to burners with low NOx emissions during fuel combustion. Low NOx burners can reduce NOx emissions during combustion. The nitrogen oxides produced in the combustion process are mainly no and NO2, which are commonly referred to as nitrogen oxides NOx.

Principle of low nitrogen burner
The precombustion chamber of low nitrogen burner is a high-efficiency, low nitrogen staged combustion technology developed and researched in China in the past 10 years. The precombustion chamber is generally composed of primary air (or secondary air) and fuel injection system. The fuel and primary air are rapidly mixed to form a fuel rich mixture in the primary combustion area of the precombustion chamber. Due to lack of oxygen, only part of the fuel is burned, and the fuel releases volatiles in the oxygen poor and low flame temperature primary flame area, Thereby reducing NOx generation. Any low nitrogen combustion technology is essentially a technology that controls the combustion process. According to the 20-year experience in the use of low nitrogen burners in Europe and the United States, it is not enough to replace or transform the burners for industrial boilers to achieve truly sustainable and reliable low nitrogen combustion. It is also necessary to upgrade the combustion control device, such as adding a "timely control" combustion control device. The mixing promoting burner is designed according to this principle.

The difference between low nitrogen burner and ordinary burner
Low-nitrogen burner is a general term for a burner that optimizes overall emission and combustion technology on the basis of the original boiler to reduce NO3 and nitrogen oxides. Low-nitrogen burners, by adjusting the combustion air and combustion head, can obtain the best combustion parameters. According to the operation and operation mode, it is divided into: one-stage, two-stage, progressive two-stage and progressive two-stage with proportional regulator, etc. (the latter implements proportional adjustment operation) Low NOx burners are roughly divided into the following categories: stage burners, self-recirculation burners, rich-lean burners, split flame burners, hybrid-promoting burners, low NOx pre-chamber burners, etc. Each has its own advantages. What is the difference between a low nitrogen burner and an ordinary burner? 1. Save costs and reduce expenses 2. Time saving: The newly purchased boiler has a long cycle and a long waiting time, which affects production, while the low-nitrogen transformation requires only a short period of construction to complete the transformation. 3. The subjective factor of low-nitrogen transformation is caused by the general environment. In the long run, it is a good living environment for future generations. At present, it is a requirement of documents. Therefore, it is necessary to pass this level in order to produce. Shenzhen Zhongli Weiye Electromechanical Equipment Co., Ltd., on the basis of absorbing domestic and foreign advanced technology and craftsmanship, has accumulated many years of wisdom and experience in burners, and the accuracy, stability and reliability of products are in an important position in China.

Types of combustion of low nitrogen burners
1. Stage burner The stage burner designed according to the principle of staged combustion makes the fuel and air mix and burn in stages. Since the combustion deviates from the theoretical equivalence ratio, it can reduce the generation of nitrogen. 2. Self-recirculating burner One is to use the pressure head of the combustion air to inhale part of the combustion flue gas, enter the burner, and mix and burn with the air. Due to flue gas recirculation, the heat capacity of the combustion flue gas is large, the combustion temperature is reduced, and the NOx is reduced. Another type of self-recirculating burner is to directly recirculate part of the flue gas in the burner and add it to the combustion process. This kind of burner has the dual effects of suppressing nitrogen oxides and saving energy. 3. Concentrated burner The principle is to make part of the fuel burn too rich and the other part burn too lean, but the overall air volume remains unchanged. Since both parts are burned off-stoichiometric, the NOx is very low. This type of combustion is also known as off-stoichiometric or non-stoichiometric combustion. 4. Split flame burner The principle is to divide a flame into several small flames. Due to the large heat dissipation area of ​​the small flames and the lower flame temperature, the "thermal reaction NO" decreases. In addition, the small flame shortens the residence time of oxygen, nitrogen and other gases in the flame, and has obvious inhibitory effects on "thermal reaction NO" and "fuel NO". 5. Mixing-promoting burner The residence time of the flue gas in the high temperature area is one of the main factors affecting the amount of NOx generation. Improving the mixing of combustion and air can reduce the thickness of the flame surface. Under the condition of constant combustion load, the flue gas is at high temperature on the flame surface. The residence time in the zone is shortened, thereby reducing the amount of NOx generated. Mixing-promoting burners are designed according to this principle. 6. Low nitrogen pre-combustion chamber burner The pre-combustion chamber is a high-efficiency, low-nitrogen staged combustion technology developed and researched in my country in the past 10 years. The pre-combustion chamber is generally composed of primary air (or secondary air) and a fuel injection system, and the fuel and primary air are rapidly mixed. A fuel-rich mixture is formed in the primary combustion zone in the pre-combustion chamber. Due to lack of ox
