steam boiler repring seal gujtat

Anyang City Children's Welfare Institute, director of the other fast condolences Group thanked welfare Xiqianxinzhi just for my company still insisted to visit the children feel very warm and happy. Fang Group, as a caring corporate fast, for five consecutive years of uninterrupted adhere to visit the orphanage children, and brought them all kinds of necessities and school supplies to children's lives to bring a dash of color.

15 ton wood pellets steam boiler repring seal gujtat advantages:

1. Full combustion

First, the combustion efficiency of the boiler Commercial Gas hot water boiler is mainly used for heating and bathing and other aspects of the use, hence the need for all-weather, uninterrupted water heating. Be the first to know when purchasing a thermal efficiency of the boiler. It is noted that the boiler flue gas temperature, excess air coefficient, aspects fuel combustion efficiency, the furnace wall strength, heat dissipation (specifically, the factor that affects the thermal efficiency of the boiler see next article). The level of combustion efficiency of the boiler will determine the cost of boiler. Second, the boiler circulating pump means in a gas hot water boiler entire operation, the circulating pump is one of the most easily damaged component. Should choose the temperature resistance, the use of small noise, vibration boiler, this boiler service life will be greatly enhanced. Third, the boiler protection device is not only a good boiler thermal efficiency and the use of part-resistant, protective device is also very important. When the condition occurs more unexpected low and high temperature, the water level is too high, too low water level, the boiler should have a significant and sensitive alarm devices, to ensure the safety of the boiler. Fourth, the boiler anti-jamming device taking into account the special nature of commercial gas hot water boiler, the boiler needs to pay attention to whether there is anti-jamming device, the device not only related to the life of the boiler, but also related to the stability of the equipment, can not be ignored .

The harm to the boiler caused by poor water quality

Poor water quality means that the water contains more impurities. The raw water in the boiler feed water may contain impurities such as suspended solids, colloids, organic matter, inorganic salts, heavy metal ions, and dissolved gases. If this water is not treated, it will bring the following hazards once it enters the boiler: 1, scaling When suspended solids, colloids, and inorganic salts are heated or exceed their saturated concentrations, they will settle out and form sludge and scale, which will greatly affect the heat transfer efficiency of the boiler and the boiler water circulation, fuel waste, damage to the heated surface, decrease in boiler output, and cleaning. The amount is increasing. The amount of washing is increased. It was determined that there was a 1 mm thick scale, a waste of 10% fuel, and a 10 kgf/cm2 boiler. When operating without scale, the wall temperature was 280. C, after the 1 mm thick silicate scale is formed, the wall temperature rises to 680 due to the increase of thermal resistance. C, at this time, the strength of the steel plate is reduced from 40 kgf/cm2 to 10 kgf/cm2, which causes the boiler pressure to drop, and the furnace wall is cracked, bulged, and even broken. In the case of severe scaling, serious accidents such as furnace tubes, waterways, furnace shutdowns and boiler explosions may occur, and the freezing of cracks in production equipment and heating equipment may occur from time to time. When chemical cleaning and descaling, improper pickling or pickling frequently affects the life of the boiler and pollutes the environment.

2, corrosion: Poor water quality causes metal corrosion, which causes damage to the metal components of the boiler. Metal corrosion products form new structural substances, and scale corrosion occurs, which accelerates the damage of metal components.

3, soda water together: The phenomenon that water droplets in the furnace of a steam boiler are carried away by a large amount of steam is called soda water. One of the reasons for this is that the water contains more impurities such as sodium chloride, sodium phosphate, silicide, and organic matter. The co-existing of steam and water will cause serious pollution of the steam. The superheater pipe and the steam flow pipe will accumulate salt. In severe cases, the pipeline will be blocked, the steam temperature will drop, and water and corrosion will be broken.

4, caustic embrittlement: It refers to irregular damage-explosion caused by low carbon steel, alloy steel and stainless steel when the tensile stress exceeds the yield point and is in contact with concentrated caustic soda solution.
