why do we need two steam boilers for hospitals
Boiler in concept and requirements if there are unknown? In knowledge and learning to master the boiler, the following will be specifically related to their work, but also is something new for everyone by learning to make their own progress in their learning on the road, so you can make yourself benefited shallow, and there will be harvest. 1. condensing gas boiler in the boiler, what is its core technology? Condensing the gas boilers, their use of technology, and technology for condensing the two non-combustion technology. In the condensation technology, the main advantage is the ability to reduce heat loss caused by the combustion of fuel, to thermal energy absorption efficiency, thereby reducing emissions of harmful substances and produce, to avoid environmental pollution. And smokeless combustion technology, it is possible to reduce the emissions of nitrogen oxides, prevent acid rain and the greenhouse effect. 2. The high-pressure boiler tube boilers, the specific requirements? Boiler, high pressure boiler tube which it is used, on the properties, belonging to a seamless steel pipe. Therefore, in the manufacturing method, it is consistent with the seamless steel tube, but its steel requirements are very strict, because it is by its working environment in which to decide. General, is required to have high strength, and good resistance to oxidation and corrosion rust performance. And, can also durable.
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.
Gas-fired why do we need two steam boilers for hospitalss are advantages in the use of an environmentally friendly energy-saving device: With the constant innovation designer redesign machinery, for the operation of the device, all starting from the simple and convenient, gas steam boiler is not only simple in operation, and for the safety of the operation there is a better guarantee; the use of the advantages of saving: the steam boiler with a high-temperature low-pressure gas used features, such as it greatly reduces the pressure level of heat equipment, then the direct benefit is to reduce the equipment investment. The proportion of raw materials in contact with air is also a statement, only the right amount of the right amount of fuel and air to form a combustion ratio to be able to burn efficiency, but also allows gas emission reductions, to achieve the dual energy saving, very convenient. It may be equipped with gas steam boiler in accordance with the amount of steam actually required, thus reducing waste of energy. The higher the degree of matching required and actual theory supplied energy the better. It may be continuous blowdown water with heat by heat exchange, thereby improving water temperature deoxygenated water. Such mechanical equipment gas steam boiler, used more in line with the requirements of environmental protection requirements of today, it is widely used.
We produce why do we need two steam boilers for hospitals is a very important part of the device, this provides a quick way to our gas steam boiler, after use, we found an excellent energy-saving effect boilers, flue gas discharge temperature is lower than the previous boiler equipment many, in line with national environmental provisions of the boiler equipment. --customer feedback
