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.

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.

A steam boiler is an industrial boiler that heats water to a certain parameter and generates high-temperature steam. Water is heated into steam in the drum, and the furnace gives out heat, which is the principle of a steam boiler. Steam boiler belongs to special equipment. Boiler design, processing, manufacture, installation and use must be supervised by the technical supervision department. The user can only use the steam boiler by obtaining a certificate of use of the boiler. According to fuel (electricity, oil, gas), steam boiler can be divided into three types: electric steam boiler, fuel steam boiler and gas steam boiler. According to the structure, vertical steam boiler and horizontal steam boiler can be divided into small and medium steam boilers. Double-return vertical structure and large-scale steam boiler are mostly three-cycle horizontal structure. Steam boiler scale inhibitor is a composite product composed of organic phosphonic acid and polycarboxylic acid, which has high corrosion inhibition and scale inhibition. After washing the gas steam boiler, the water distribution tank becomes the water wall bottom box and the temperature resistance is very good, which can be effectively applied to the water treatment of the low pressure boiler. Gas-fired steam boilers are suitable for corrosion and scale inhibitors, as well as for seawater desalination, distillation and automobile water tanks. The use of scale inhibitors in steam boilers can effectively suppress copper tubes and carbon steel composite components in the process; anti-F E3, Cu 2 accelerates corrosion resistance. The scale inhibitor used in gas-fired steam boiler is the guarantee of the safety of the equipment, it can be easily removed completely and at the same time reduce, the operation is simple, safe and reliable. The scale inhibitor used in gas-fired steam boiler is simple, can be discharged after neutralization, safe and environmentally friendly. It can reduce the use of scale inhibitors to maintain the performance of gas-fired steam boilers, which is conducive to the direct use of users and regular cleaning and maintenance of gas-fired steam boilers, saving equipment maintenance costs. According to the specific operation conditions of gas-fired steam boiler, descaling is simplified and easy to install and operate.
