How to select suitable burner for steam boiler?
Steam boiler is a fuel burning industrial boiler that provides steam for industrial production. As the core component of the boiler, the burner of the boiler plays a vital role. To adapt the burner of the boiler, the following issues should be considered:
1. Fuel: enterprise users who use steam boilers should first determine which fuel to use, and then select the burner according to the type of fuel, which is the premise of selecting the appropriate burner.
2. Technical parameters of equipment: calorific value and power can be included in the technical parameters of steam boiler. After selecting the fuel, the user can select the appropriate burner according to the calorific value and power of the supporting equipment.
(1) Calorific value: after selecting according to the calorific value of the user, the user can select the appropriate fuel burner equipment, or select the appropriate recorder according to the auxiliary power supply equipment.
3. Furnace temperature and pressure: When purchasing burner gas, it is necessary to determine whether the pressure in the furnace is positive, negative, pressure and temperature. Due to the different temperatures in the furnace and the different burner structures, the selection of materials is also different; The burners selected in the furnace overcome the pressure, and the burners selected to overcome the pressure in the furnace negative pressure.
(1) Furnace temperature: furnace temperature is the core indicator. The boiler burner manufacturer must have a clear understanding of which equipment it belongs to, the positive and negative pressure in the furnace, the pressure and the temperature. Due to the type of temperature in the furnace, the structure of the burner is different, so we should choose different materials. When the pressure gas is used as the fuel calorific value, because the calorific value of various gases is different, the pressure is also different, so when selecting the burner, it should be explained to select the appropriate burner, and its quantity, calorific value and pressure should be explained to avoid the risk caused by wrong selection. For the equipment required by the temperature accuracy of the adjustment mode, several kinds of fire control (only one operating point of the burner operation mode) can be selected to control the secondary fire (the working mode of the burner is two working points of the small furnace, and the two working switches have sudden changes), one line one line (the two working points of the small burner are smooth and gradual)
4. Boiler emission indicators: especially NOx emission concentration has a great relationship with coal type, boiler type and burner type. For boilers in operation, the boiler type has been determined. However, in recent years, in order to increase profitability and cope with the changing electric coal market, most of the coal used by coal-fired power plants is mixed with inferior coal. Therefore, before the transformation of low nitrogen combustion technology, the existing main coal types and common coal types of boilers should be fully evaluated, In the feasibility study of the transformation, due to the improper selection of coal type, the effect of NOx emission reduction after the transformation is not obvious and there are many new problems. Next, it is to conduct a thorough test on the boiler in operation, fully evaluate the combustion performance, steam parameters, heating surface wall temperature, coking and slagging, operation adjustment, thermal automation and other problems existing in the operation of the boiler, and put forward the scientific and reasonable transformation expected objectives, weigh the boiler economic indicators and environmental indicators, And effectively improve the existing problems through transformation.
After mastering these knowledge, I believe that the design of steam boiler is very simple and the application of boiler burner is also relatively good. At present, the natural gas boiler dominated by carbon peak has been widely used in China, and has become the focus of energy-saving and environmental protection transformation in thermal industry. In addition to the boiler burner shell, Europa has mastered the ultra-low nitrogen core technology. Europa boiler burner is absolutely the first choice for your boiler transformation!
