Bayer coating energy-saving products are a new generation of high-efficiency energy-saving products developed and produced by our company with independent intellectual property rights. This product has been developed with various additives and is a solvent-free two-component chemical reaction adhesive. In the development and production, adding an efficient accelerator greatly improves the bonding strength, accelerates the curing speed, promotes the thickening of the adhesive, and can be applied to vertical working surfaces without flowing or polluting. Significant breakthroughs have been made in production processes, bonding techniques, construction methods, and other aspects. In terms of material formula and production process, this product selects imported raw materials, which are the main materials after fine chemical synthesis. 60% of the particles have a circumference of less than 1 nanometer, ensuring stability and service life such as emissivity, wear resistance, and high temperature resistance.
The energy-saving technology of boiler Bayer coating is widely used in the construction of various industrial furnace walls such as coal-fired boilers, circulating fluidized bed boilers, chain furnaces, and three gas furnaces, including ash cleaning, pit filling, coating, anti-wear, radiation, and drying. It is more obvious that it can quickly increase the temperature inside the furnace to achieve energy saving and high efficiency. Whether the technical quality meets the technical standard requirements largely depends on the technical performance of the Bayer coating products themselves.

During the construction process, a unique pre-treatment process was adopted to allow the coating to penetrate into the heat absorbing body of the original furnace wall, making it more firmly bonded at high temperatures and never naturally falling off. Its main performance and technical indicators have exceeded the infrared technology standards and reached the international advanced level.

Due to the relatively late use and wide geographical area of sulfide bed boilers in China. Due to the diverse forms of coal used, the reasons for wear and tear are also different. So far, no suitable method has been found to deal with wear and tear. Many home appliance factories across the country now use thermal spraying method. According to relevant statistics, 65% of sulfide bed boilers in China adopt thermal spraying measures (mostly CFB12MW-150MW), but the satisfaction rate is only 30%. Some are also affected by thermal spraying measures, resulting in many legacy issues.
The hot combustion adjustment test of the boiler is an important means of boiler testing and operation. Through the boiler power field test, the following four problems can be solved: 1. It provides an acceptance method for the overall acceptance of the boiler after overhaul and before cold start, and can create good operating conditions for the ignition and start-up of the boiler unit. 2. Through comprehensive air volume measurement, calibration, and leveling tests, accurate control of burner and furnace air distribution under hot boiler conditions can be achieved. 3. Eliminate defects in the burner, analyze the characteristics of the burner and its jet, pre adjust the burner, provide direction for boiler thermal combustion adjustment, and reduce the blindness and experimental workload of thermal adjustment. 4. Through the cold state modeling test of the furnace, it is possible to observe intuitively whether the distribution, diffusion, disturbance, mixing, and other conditions of the airflow inside the furnace are good
Test objective 1: To determine the uniformity of air distribution in the combustion system, to determine the uniformity of primary and secondary air distribution in the swirl burner, and to determine the air flow characteristics of the air and smoke system damper. 2. Determine the resistance characteristics of the burner and combustion system. 3. Determine the fluid dynamic characteristics of the burner. 4. Study the aerodynamic field principles of furnace flame filling and furnace coking. 5. Study the influence of boiler combustion on the wall temperature of the heating surface, the deviation of steam temperature, and the aerodynamic characteristics of abnormal combustion conditions.
The main tasks of boiler operation adjustment are: (1) maintaining good combustion of the boiler and improving boiler efficiency; (2) Maintain normal steam temperature, steam pressure, and steam drum water level; (3) Maintain the quality of saturated steam and superheated steam to be qualified; (4) Maintain the evaporation capacity of the boiler to meet the needs of steam turbine and heat users; (5) Maintain the safe and economical operation of boiler units. The purpose of boiler operation adjustment is to maintain stable steam temperature, steam pressure, steam drum water level, excess air coefficient, furnace negative pressure, etc. within the rated or allowable range by adjusting fuel quantity, feedwater quantity, cooling water quantity, air supply volume, and induced draft volume.
The currently used flue gas recirculation method extracts a portion of low-temperature flue gas before the air preheater of the boiler and mixes it directly with the supply air before sending it into the furnace. This not only reduces the combustion temperature, but also lowers the oxygen concentration, thereby reducing the NOx emission concentration. The effect of reducing NOx emissions by flue gas recirculation method is related to the fuel type and flue gas recirculation. Experience has shown that when the flue gas recirculation rate is 10-15%, the NOx emission concentration of gas stoves can be reduced by more than 40%. The reduction rate of NOx increases with the increase of flue gas recirculation rate. And it is related to the type of fuel and combustion temperature. The higher the combustion temperature, the greater the impact of flue gas recirculation rate on NOx reduction rate.
The transformation goal is to combine low nitrogen combustion with SNCR denitrification to achieve ultra-low emissions, with the concentration of nitrogen oxides in the flue gas at the boiler environmental protection detection point not exceeding 50mg/Nm3 (the oxygen content in the flue gas at the environmental protection detection point is not more than 8%, the oxygen content in the flue gas after the boiler superheater is not more than 4%, the amount of coal gas burned is not more than 25% of the total fuel heat, and the amount of coal slurry burned is not less than 45% of the total fuel heat). Pure low nitrogen combustion (cutting off ammonia water) achieves denitrification in the furnace, and the concentration of nitrogen oxides in the flue gas at the boiler environmental protection detection point is not more than 250mg/Nm3 (the oxygen content in the flue gas at the environmental protection detection point is not more than 8%, the oxygen content in the flue gas after the boiler superheater is not more than 4%, the amount of coal gas burned is not more than 25% of the total fuel heat, and the amount of coal slurry burned is not less than 45% of the total fuel heat).
