How to select suitable burner for steam boiler?
Steam boilers are now essential in many industries, and industrial boilers are divided into four categories; Steam boiler, hot water boiler, steam-water dual purpose, organic heat carrier heat transfer oil boiler. Steam boiler is divided into coal-fired steam boiler, oil-fired steam boiler, electric heating steam boiler and others according to different combustion media; Hot water boiler is divided into coal-fired hot water boiler, oil-fired hot water boiler, electric hot water boiler and others according to the combustion medium.
As the core component of the boiler, the burner plays an important role. So how do we choose the appropriate burner when designing the steam boiler?
Generally, the boiler shall be installed in a separately built boiler room, or when the boiler room is connected with other buildings or installed in it, it shall comply with the relevant provisions of the current Supervision Regulation on Safety Technology of Steam Boilers, Supervision Regulation on Safety Technology of Hot Water Boilers, and Code for Fire Protection Design of Buildings.
We mainly consider the following points when fitting the boiler burner:
Calorific value: After selecting according to the calorific value of the electricity user, the user can select the appropriate equipment by selecting the fuel burner, and you can select the appropriate recorder according to the auxiliary power supply equipment.
The temperature in the furnace is the core indicator. The boiler burner manufacturer's instructions must indicate which type of equipment his equipment belongs to, whether the pressure in the furnace is positive or negative, how much pressure, and how high the temperature is. Due to the type of temperature in the furnace, the burner structure is different, and different materials are selected; The positive selection of the burner of the furnace is to overcome the furnace pressure of the low-pressure burner at a high pressure. When the calorific value of the gas selects the pressure gas as the fuel, because the calorific value of various gases is different, and the pressure is also different, so when selecting the burner manufacturer of the fuel type burner, the quantity, calorific value and pressure of the appropriate boiler burner shall be specified to avoid the risk caused by the wrong selection. For the equipment required for the temperature accuracy of the adjustment mode, you can select some fire control (only one burner's operating mode operating point), in the second stage fire control (the burner's operating mode is small fire-fire two working points, and the sudden change in the two working switching points), line by line (small mode burner's fire-fire two working points, and the switching between the two working points is smooth and gradual), Adjust the burner (any point within the working range under the burner combustion mode can be left to output the balance of heating furnace demand from the system).
The emission index of boiler, especially the emission concentration of NOx, is closely related to the coal type, boiler type selection and burner type. For the boiler in operation, the boiler type has been determined. However, in recent years, in order to increase the profitability of coal-fired power plants and cope with the changing market of electric coal, the coal quality used by the boiler is mostly mixed and inferior to the original design coal type. Therefore, before the transformation of low nitrogen combustion technology, First of all, it is necessary to fully evaluate the existing main coal types and common coal types of the boiler. In the feasibility study of the transformation, due to the improper selection of coal types, the NOx emission reduction effect after the transformation is not obvious and there are many new problems. Secondly, it is necessary to carry out a thorough test on the boiler in operation, and fully evaluate the problems of combustion performance, steam parameters, heating surface wall temperature, coking and slagging, operation adjustment, thermal automation and other aspects in the operation of the boiler, Put forward the expected goal of scientific and reasonable transformation, weigh the boiler economic indicators and environmental indicators, and effectively improve the existing problems through transformation.
If the atomization of heavy fuel oil is selected, the heavy oil burner can be selected according to the fuel oil of the mechanical atomization boiler burner, the burner F area of the medium atomizer, different geographical environments, and different environments with different viscosity requirements of the burner. After understanding this knowledge, I believe that steam boiler design is easy and the application program of boiler burner is better.
Under the guidance of the national strategy of carbon peak, natural gas boilers are now widely used and become the focus of energy-saving and environmental protection transformation in the thermal industry. In addition to the shell of the boiler burner, Europa has mastered the core technology of ultra-low nitrogen. The boiler burner is absolutely the first choice for your boiler transformation!
