Low NOx emission combustion boiler technology a boiler combustion boiler hypoxic hypoxia NOX emissions from combustion is the easiest way to control. And a combustion burner system does not need to make any changes, only control air flow into the furnace in operation, pulverized coal combustion process as close to the theoretical combustion air amount. Low oxygen combustion scheme can reduce NOX emissions by 20% to 30%. The program practical application subject to conditions. Low oxygen furnace, will increase the amount of unburned carbon, and more difficult for the flame of burning coal more obvious; Further, the CO concentration is also increased so that smoke, which will cause decreased boiler efficiency. Another problem is that for certain boilers, hypoxia causes the main combustion steam or reheat steam temperature is low. The burning coal to immediately, boiler efficiency and reduce the magnitude of steam temperature and other properties to determine the appropriate control value of flue gas oxygen furnace outlet (at or economizer) the specific embodiments. Second, air staged combustion technique combustion air into a plurality of strands, it is gradually mixed and pulverized coal combustion, so you can see the local area to reduce the air-fuel ratio, and the thermal decomposition of coal in the ignition phase, due to hypoxia, and thus the nitrogen oxide generation is suppressed. Air classification may be implemented within the combustor, the boiler can be completed within. 85% of the amount of air required for complete combustion is introduced to the main burner, the main burner combustion zone is insufficient oxygen for the fuel-rich conditions. Due to insufficient amount of oxygen, the flame temperature is low, the amount of nitrogen oxides to less generation of fuel nitrogen intermediates (e.g., NCH, NH3, etc.) will therefore not be oxidized NOX. Meanwhile, it has been possible to further reducing NOX generated in a reducing atmosphere to molecular nitrogen (N2 of), as a result reduces NOX emissions. An upper portion of the top floor is provided Ge overfire air (of OFA) spout into the furnace through which about 15% of the rest of the air, to avoid the high temperature flame zone, it is also possible to burn unburned carbon particles, to complete the combustion process.

Fang Group R & D center was officially opened fast approaching New Year party quickly ushered in a large group wedding - R & D Center was officially launched. VIP dealers from Beijing, Tianjin, Hunan, Sichuan, Fujian, Heilongjiang and Xinjiang invited to participate in the ribbon-cutting activities.

Boiler multiple protection: (1) the integration of boiler water level to protect water level and boiler design, the appearance of more compact appearance, accurately show the actual water level in the boiler body function. Coupled with dual independent electronic water level control system to achieve ultra-low water level in the boiler, low water level automatic adjustment function, the normal water level, high water level, ensure that the boiler in a variety of unforeseen circumstances foolproof, secure home. (2) steam pressure protection ☆ pressure controller: selection of high sensitivity of the pressure controller, the pressure is high, or low levels of signal to the electrical switch, other control lines or automatic control chain protection. Common pressure controller and pressure gauge, vapor pressure overpressure alarm can cut off the burner limit is reached; the pressure controller may be single or double fire burning fire the actual operating pressure regulator. ☆ safety valve: safety valve is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design with the school, the exhaust steam pressure relief, to ensure the normal operation of the boiler. (3) having a burner flame protection flame protection inlet means, combustion function is to detect, when the ignition failure or extinguish combustion middle, immediately off the burner into the oil (gas) solenoid valve, the blower continues to operate at this time, the furnace was purged combustible residual gas, after 20 to 30 seconds purge, and various auxiliary blowers automatically cut off power, the boiler operation stops. (4) self-locking power failure protection case, the boiler shutdown immediately burst self-locking power interruption, if the current power is restored, the boiler will not start at any time, you must reset release self-locking, to re-start the ignition.

The origin of the gas on the principle of using gas community steam boiler price steam heating boiler called gas steam boiler. HTF, also known as organic heat carrier medium or hot oil, use as an intermediate heat transfer medium in the industrial heat exchange process has been more than 50 years of history. Based forced circulation design and development of once-through boiler. Typically coal, oil, gas fuel to oil as the medium, using a thermal oil circulation pump to force the liquid circulating medium, the heat energy to a heat transport device and then return again heated furnace, having obtained at low pressure high operating temperature, and can perform high-precision control of the working medium run. High system thermal efficiency, easy operation and maintenance, the closed-cycle heat to the atmosphere, the service life, the liquid or vapor phase delivery extended heating boiler. Gas steam boiler return three-coil design, the system is set up expansion of the water tank, provides low temperature heating. Using the coil structure, sufficient heating surface, expands sufficiently absorbed. Imports of low NOX burner, combustion, are environmentally friendly products. Boilers can use advanced touch-screen computer controller and digital computer controller automatic control. Having a thermostat, automatic ignition, and differential pressure, over-temperature, flame protection. Boiler manufacturing practices, in strict accordance with the relevant national standards. The use of gas steam boiler water quality requirements: Some users believe that as long as gas steam boiler water is held on it, the water quality indiscriminately. In fact, the use of water or gas steam boiler influential, small advice you to choose clean tap water. Because if there are impurities in the water, then the use of this device with impurities of water will have some impact. Impurities junction thick layer of scale on the inner wall of the gas steam boiler. The scale will gradually thickened over time, which will affect the efficiency of heat conduction when a thickness of accumulation is wasted energy. If the scale appears to be cleared, so the heat is concentrated in the scale easy to distribute.
