boiler thick wall hemispherical head

Note purpose and turbine operating in parallel: there are two or more than two parallel conveying gas turbine operating in parallel to the same named pipe. Objective parallel operation is possible to increase or decrease the number of operating wind turbine to accommodate a wider range of boiler thick wall hemispherical head flow regulation, both to ensure the economic operation of each device, and not because of an accident in which a piece of equipment outage caused by the master. Another fan also avoid a single run, a huge fan structure, high cost of equipment, manufacturing difficulties and other issues.

The harm to the boiler thick wall hemispherical head 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.

One of our star products fast side - condensing gas hot water boiler thick wall hemispherical head, for example.

1, you first need to boiler safety inspection, each valve instrument is loose, hydrophobic drain port is open and a number of inspections to ensure the safety of boiler index at normal levels.

2, connected after the water system, water in the system, and observe the pressure gauge pressure changes inside the boiler, water comes to a stop within the defined range, check all connections for loose water leakage phenomenon.

3, the power supply is turned on, press the power button, so that rotation of the pump, the discharge of each heat exchanger coil in the air or manually unscrew the distal end of the heat exchanger exhaust valve exhaust gas after the exhaust gas pressure drops then added water until the pressure reaches the operating range.

4, the injection water enough, the smoke pipe connection, connect to the gas source, the ignition operation, red light was observed sub-control board, the power lamp flashing slowly after the letter, after successful ignition flashes quickly.

5, the boiler has been adjusted at the factory parameters, users no longer need to be adjusted on-site, but are subject to change (with comparative plains) if the local gas heating value days, air pressure or altitude height shall be burned system analysis and adjustment, the specific method of operation requires professional skill in the art by adjusting combustion system analysis methods and operation.

Meanwhile, the party also fast boiler thick wall hemispherical head design automation control systems, temperature, pressure, and other parameters automatically adjust the water level, real-time monitoring anti-smoke temperature, oxygen content and changes in safety interlock, even if unattended, the boiler can function . In mid-January 2019, under the fast boiler joint efforts of all staff, boiler manufacturing is completed, the pipeline project has reached Hwashi ground, and successfully complete the installation and commissioning work. At present, the boiler has been put into the urban underground pipeline construction and maintenance projects in order to contribute to building a better city.
