Performance advantages
》》Low cost: Based on the analysis and summary of the relationship between the condensation efficiency of water vapor in flue gas and exhaust temperature, the relationship between condensation and thermal efficiency, and the corrosion rate of condensed water on different steel grades, a condensing boiler is designed with a reasonable heating surface to greatly reduce the exhaust temperature, ensure that the water vapor in the flue gas reaches the required condensation rate, absorb and utilize the sensible heat in the flue gas and the latent heat of vaporization released during the condensation process of water vapor, thereby greatly improving the thermal efficiency of the boiler.
》》High efficiency: Calculated based on the low calorific value of the fuel, the thermal efficiency exceeds 100%. The boiler has high thermal efficiency; Adopting a fully automatic burner, the water supply is continuously electrically regulated, resulting in high combustion efficiency.
》》Safe and stable: Designed with multiple protection functions such as overheating, overpressure, water shortage, leak detection, and shutdown, the boiler operates safely and reliably. The programmable logic controller (PLC) has sufficient reserved ports and modular expansion modules, which can achieve group control, remote monitoring, and building monitoring, reducing redundant investment for the development of users' special needs. Multiple boilers can be connected to the network for use, and there is no need to set up a main console to automatically select the number of operating boilers and allocate the load of each boiler.
》》Space saving: The finned condenser heat exchanger effectively reduces the exhaust temperature. In order to prevent acidic corrosion of exhaust condensate, the condensation energy-saving device uses finned tubes made of ND material. Compared with light tubes, its heat transfer efficiency is more than twice that of straight tubes. Adopting frequency conversion continuous water supply control can save 40% of electrical energy.
Working principle
1. Triple return structure: Adopting the internationally popular pot shell triple return and fully wet back structure, the combustion chamber is designed with a large volume to ensure more complete combustion. The fuel burns under slight positive pressure inside the furnace, and the high-temperature flue gas enters the flue tube bundle through a 180 ° bend in the combustion chamber along the furnace, and then enters the second tube bundle through a 180 ° bend in the compressed front smoke box. After convective heat exchange, it is discharged into the atmosphere.
2. Waveform furnace chamber: The combustion chamber adopts a fully corrugated furnace chamber structure, which not only enhances the disturbance of flue gas, but also increases the radiation heat transfer area; It not only increases the stiffness of the furnace liner, but also effectively reduces the expansion stress of the furnace liner; It not only enhances the heat transfer effect, but also promotes the combustion of fuel in the furnace.
3. Unique welding process for smoke tubes and tube sheets: using advanced technology of pre expansion, full welding, and then expansion joint, which not only prevents corrosion of tube gaps but also enhances welding strength; By using threaded smoke pipes with high heat transfer coefficients, the convective heat transfer effect is enhanced, the exhaust gas temperature is reduced, and the thermal efficiency of the boiler is improved.
4. Symmetrical hinged front and rear smoke doors: easy to open, convenient for maintenance and cleaning.
5. The boiler adopts a wet back structure with fully butt welded edges, high reliability, and low maintenance costs.
6. The design of the rearview device facilitates the observation of combustion conditions.
7. Design multiple protection functions such as overheating, overpressure, water shortage, leak detection, and shutdown to ensure safe and reliable operation of the boiler.
