The recent good news story: Union Square soon Group was named the provincial Federation of factory affairs leading group as "micro-small and medium private enterprises in Henan workers' congress building demonstration units" honorary title. Win the title, is inseparable from the efforts of all labor union workers, they work with their own solid foundation, effective operational mechanism and splendid achievements successfully nominated and award winning. Over the years, the Labor Union under the correct guidance of urban levels of trade unions, under the correct leadership of the Party, Comrade rely on the staff, smooth internal management channels, good to play the democratic management of conflicts "relief valve" business "stabilizer" and developing the "catalyst".

Gas steam boiler advantage of reducing the use of heating equipment with the use of pressure gas steam boiler advantages: With the mechanical designer to redesign innovative, simple and convenient operation of the device. Gas-fired steam boiler is not only simple, but also to better ensure the safety of the operation. Energy-saving advantages: high-temperature low-pressure gas steam boiler has the characteristics of greatly reducing the stress levels of heating equipment, directly benefit from the reduction in equipment investment. Ratio of said feedstock is contacted with the air. Only the proper amount of fuel and an amount of air to form a combustion ratio, in order to achieve efficient combustion, simultaneously, which can reduce emissions, to achieve the dual energy, very convenient. Gas steam boiler according to the actual amount of steam required is equipped, it can reduce energy waste. The higher the match between the actual demand and supply theory, the better the energy saving effect. Continuous discharge of heat may be utilized by heat exchange of water, thereby increasing the water temperature deoxygenated water. The current environmental requirements to use, such as a mechanical device for a gas boiler is more widely used. In severe cases, severe water vapor, increasing the salt content of the small gas steam boiler, water hammer sound in steam lines, steam dripping out at the connecting flange; if economizer tube or pipe rupture, water steam flow is less than the flow rate when the water occurs, the opposite phenomenon occurs; severe when dry, can see the red hot tube wall and to be burnt smell from the smell of the door. Meanwhile, the tube may rupture, you can hear the explosions. Steam and smoke discharge from the door and fire door. Low water interlock if the level is lower than the predetermined value, the blower, fan and grate reducer machine motor should stop running; low security level below the water line, water glass (plate) as a white; rinsing water table to determine whether the small gas-fired steam boiler whether full or slightly severe filled with water? Method: First off level gauge, tap water pipe is connected, and then open the drain cock. If you can see the water level drop from the top, it means that it is slightly filled with water, open the drain valve and place it in the normal water level. If severe filled with water, please take urgent measures to stop.

Hazard boiler scale chemical plants which boiler scale chemical plants What are the dangers? In the application process chemical plant boiler, for various reasons, the main boiler heating surface will produce a lot of fouling, and briefly describes the main hazards fouling. 1, the scale will reduce heat transfer efficiency boiler, heat boiler operating characteristics of the waste fuel boiler has a very close relationship. Internal inspection understood from the boiler, the boiler heating surface fouling occurs, the higher the heating temperature, the stronger the boiling, the more prone to fouling. Operation Practice of boilers and various data indicate that damage to the boiler fouling is mainly caused by the thermal conductivity, the thermal conductivity of steel is 1/5, will result in decreased formation of fouling of heat transfer efficiency. Thermal resistance is increased because the heat from fuel waste, low thermal efficiency. Studies have shown that analogy than 1mm, we should consume 3 to 5% of coal per scaling in the boiler. 2, the scale will shorten the life of the boiler and endanger the safe operation of the boiler from GB713-2014 "boiler and pressure vessel steel plate" inquiry found that the mechanical properties of steel will increase as the boiler temperature decreases. After the scale generated water present in the heating surface side, so that the resistance increases, the heat generated by the fuel combustion is not well transferred to the boiler water by the metal surface, resulting in the metal heating surface temperature increases overheating, reducing the structural strength of metal, prone smoke tube deformation on drum kits, tube wall area reduction and other hazards, shorten the life of the boiler and related components, a serious threat to the safe operation of the boiler. Additionally, high iron containing scale, the scale is easy to cause surface lower oxygen corrosion, scale formation and corrosion promoting the mutual drum, resulting in surface defects such as corrosion pits within the drum, the safe operation of the boiler hazard. 3, the scale will affect the water cycle boiler water circulation boiler operation of natural circulation and forced circulation divided two kinds. Boiler circulating water is balanced, whether it is rising or falling pipe tubes, should have sufficient cross-sectional area. Fouling not only the cross sectional area of ​​the waterwall tubes in the boiler waterwall tubes is reduced, but also because of a greater roughness and unevenness, the larger the flow resistance of the boiler heating surface fouling of the boiler water or steam will have some impact on the flow, the line is blocked when the scale, water circulation is stopped, the convection tubes by local temperature rise generates firing tube or tube rupture occurred partially vaporized, direct threat to the normal operation of the boiler.

By removing the impurities, dirt, scale, controlling the basicity and salt content of boiler water correctly and reasonably, the quality of boiler water conforms to the national standard, ensures the cleanliness of heating surface and meets the requirements of qualified steam quality. The service life of the boiler is extended.
