Low nitrogen gas steam generator is an efficient and environmentally friendly energy equipment, mainly used for generating steam, widely used in industrial production, medical pharmaceuticals, food processing and other fields. Here is a detailed introduction:
The low nitrogen gas steam generator adopts a tubular structure design, and the ratio of gas to air is precisely adjusted through a Venturi premixed device to achieve fully premixed and stepless combustion regulation. During the combustion process, high-temperature flue gas flows at high speed along multiple return threaded smoke pipes, fully releasing heat energy. The built-in high-efficiency condensation heat exchange system uses low-temperature return water to absorb waste heat from the flue gas, reducing the exhaust gas temperature to below the dew point and greatly improving thermal efficiency.
Low nitrogen emissionsBy adopting advanced low nitrogen burners and optimizing the burner design and adjusting the combustion process, the gas and air are fully mixed to reduce the oxygen concentration during combustion. Some equipment also uses exhaust gas recirculation technology in the furnace to send some flue gas back into the combustion chamber, further reducing the combustion temperature and effectively controlling the generation of nitrogen oxides. The emission can be as low as 30mg/m ³ or less, far below the national standard.
High Efficiency and Energy SavingAdopting a special finned tube structure and waste heat recovery device, such as the T-shaped finned tube structure used in the longitudinal sea ultra-low nitrogen gas steam generator, which has a high thermal conductivity and a large heating area. At the same time, an air preheating device and an efficient stainless steel coil condenser are installed, with a thermal efficiency of up to 98%.
safe and reliableIt has multiple chain safety protection functions, such as overpressure protection, low water level protection, leakage protection, etc. At the same time, some equipment adopts an integral rolled film wall structure, which has a small water retention capacity, less heat medium water, and a gradient rise of furnace water from bottom to top, with good safety. It is also equipped with protective measures such as anti dry burning and anti overheating.
intelligent controlEquipped with PLC intelligent control system or fully automatic intelligent electronic control system, all operating states can be easily seen on the LCD screen, making it convenient for operators to grasp the equipment's operating status at any time. It can achieve automatic control and management of combustion, and has functions such as combustion monitoring, fault display and alarm.
