boiler made in China price

Jingzhou City, Hubei is located in Jianli County Supervisor Bureau for a food processing plant emergency inspection and maintenance, the timely processing of the security risks of the boiler made in china price. At the meeting held later, the city supervisor Bureau emphasized the specific guidance boiler safety management.

Gaz than steam boiler made in china price should be how to calculate? Q: gaz than coal-fired steam boiler coal calorific value multiplied by a simple algorithm efficiency boiler steam is then divided by this simple calculation does not assume that the heat of the boiler efficiency of 80%, coal calorific value 5500, whether the amount of steam generated a ton of coal can be calculated as follows * 0.8 = 5500/600 = 7.3, ie: gaz ratio of 7.3 can be calculated simply, is this right? A: According to your argument: the amount of steam a ton of coal produced, commonly referred to as the evaporation rate of the fuel, commonly known as steam coal ratio. The calculation formula is: base received low calorific value of coal is then divided by multiplying the thermal efficiency of the boiler (steam heat feedwater minus heat). You said above is correct.

4, the scale of the boiler made in china price which harm?

a. heat pipes are burnt due to overheating poor thermal conductivity of the scale, the scale too thick heating tube, the heating tube will cause the internal temperature not diffuse, resulting in cracking of the outer tube heating the tube.

The harm to the boiler made in china price 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.
