How to choose a suitable burner for a steam boiler?
A steam boiler is a fuel burning industrial boiler that provides steam to industrial production. As the core component of the boiler, the burner plays a crucial role in adapting the boiler burner, mainly considering several issues:
1. Fuel: Enterprise users who use steam boilers need to first determine which fuel to choose, and then choose a burner based on the type of fuel, which is a prerequisite for selecting a suitable burner.
2. Equipment technical parameters: Heat value and power can be included in the technical parameters of steam boilers. After selecting fuel, users can choose the appropriate burner based on the heat value and power of the supporting equipment.
(1) Heat generation: After selecting based on the user's calorific value, the user can choose the appropriate fuel burner equipment or choose the appropriate recorder based on 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 or negative, as well as the level of pressure and temperature. Due to different temperatures inside the furnace and burner structures, the selection of materials also varies; The burner selected in the furnace overcomes high pressure, and a burner that overcomes pressure is selected for negative pressure in the furnace.
(1) Furnace temperature: Furnace temperature is the core indicator, and boiler burner manufacturers must have a clear understanding of which type of equipment their equipment belongs to, the positive and negative pressure inside the furnace, the pressure and temperature. Due to the type of temperature inside the furnace, the structure of the burner is different, so different materials need to be selected. When using pressure gas as fuel calorific value, due to the different calorific values and pressures of various gases, when selecting a burner, it should be noted that the appropriate burner should be selected, and its quantity, calorific value, and pressure should be explained to avoid the risk of incorrect selection. For equipment that requires temperature accuracy in the adjustment mode, several types of fire control can be selected (with only one operating point for the burner operation mode) to control the secondary fire (the burner's working mode is two working points of the small furnace, and two working switches have sudden changes), one line at a time (the two working points of the small burner's fire are smooth and gradual)
4. Boiler emission indicators, especially NOx emission concentration, are closely related to coal type, boiler type, and burner type. For operating boilers, the furnace type has been determined. However, in recent years, coal-fired power plants have mixed most of the coal used for boiler combustion with inferior coal to increase profitability and cope with the ever-changing electricity coal market. Therefore, before the transformation of low nitrogen combustion technology, the existing main and commonly used coal types for boiler combustion should be fully evaluated, In the feasibility study of the renovation, there are many cases where the improper selection of coal types has resulted in unclear NOx reduction effects and new problems after the renovation. Secondly, a thorough test is conducted on the operating boiler to fully evaluate the combustion performance, steam parameters, heating surface wall temperature, coking and slagging, operation adjustment, thermal automation and other issues that exist during the operation of the boiler. Scientific and reasonable renovation goals are proposed, balancing the economic and environmental indicators of the boiler, And effectively improve the existing problems through transformation.
After mastering these knowledge, I believe that the design of steam boilers is very simple, and the application of boiler burners is also relatively good. At present, natural gas boilers dominated by carbon peaking have been widely used in China, becoming a key focus of energy-saving and environmental protection renovation in the thermal industry. In addition to the outer shell of the boiler burner, Europa has mastered the core technology of ultra-low nitrogen, and Europa's boiler burner is definitely the first choice for your boiler renovation!
