Select the paper mill steam boiler dealer 4t kazakhstans need pay attention to what? Our country is not only a large agricultural country, but also a major industrial country, the use of steam boilers more and more enterprises. Steam boilers for the chemical industry, pharmaceutical companies, chemical plants, cement plants, steel mills and other thermal energy, these companies plant an important and indispensable component. Even some plants need to arrange inspection departments of routine testing boiler water ph value meets the needs of process water. Visible status steam boiler in the enterprise is still very important. 1, first of all good safety performance, good safety performance steam boiler is worthy of our choice. When we discuss what a good quality steam boiler? Generally assess its safety performance. Steam boiler explosion message appears often on television and in newspapers, national authorities will also be listed as accidents. As can be seen, in the first place it should be safe factory production, so need to choose from a manufacturer steam boiler trusted to ensure safety. 2, energy saving and environmental protection in recent years, in order for residents to return to the blue sky, the State Environmental Protection Agency inspection of the factory air pollution is particularly strict, while the country has been promoting energy conservation in heavy industry. Specializing in the production can also be optimized to improve the steam boiler section, making it meet the national standard industrial energy efficiency and environmental protection. 3, after-sale protection, then, we should choose those aftermarket manufacturer warranty. If the steam boiler failure, hot water or steam supply system will be cut, the plant will not be able to continue production. If a glitch occurs, the plant can repair overhaul, major fault will need to notify the manufacturer's service sector, and therefore the need for timely and responsible for after-sales service.
At 10:00 on September 6 and more, Harbin, a business is the purchase of a new boiler dealer 4t kazakhstan equipment installation, commissioning process when staff at a boiler pressure gauge index found that the performance of the boiler abnormal, but not so the commissioning personnel when the next step, a sudden loud noise, boiler explosion, a huge flame and furnace pressure debugging of oil spray everywhere, four commissioning personnel are subject to varying degrees of injuries, was taken to hospital for treatment .
Boiler is an energy conversion device, by entering the fuel to the boiler, chemical energy, power, etc., outputs a constant steam heat, hot water or organic heat carrier, to provide support for the heat industries. Meanwhile, the boiler is also a special equipment has a certain risk, when the boiler installation, commissioning, operation, etc., be sure to boiler operation safety first.
Now, Xiao Bian to operational safety considerations gas boiler summarize, we can refer to.
First, start, boost, steam supply
1, before the start of the preparatory work
Internal and external check: Check boiler, burner, a good state of the accessory device; action safety accessories, each of the valves, such as flexible instruments, the correct position.
Check the line voltage to meet the requirements, a variety of normal switch position, respectively, various auxiliary pump starts operating, the burner fan, oil pump is normal.
Boiler Feed: exhaust valve opening, to ensure the normal water level (just below the water level).
Firstly purging the furnace, induced draft fan suction time is usually about 10 minutes to ensure that no residual gas in the furnace, passing substitutions, and ignition for combustion air supply.
After firing is completed according to the adjustment amount of load required for combustion, the boiler into normal operation.
During startup, to closely monitor changes in water level, water boiler accident or occurrence textile full of water accidents.
Second, the normal operation
1, the water level
Fuel gas-fired boiler water table should be the red line indicating the high, medium and low water level, the operation shall not exceed the maximum safe level or below the minimum safe level.
Rinse water table at least once per shift, when there is suspicion of running water, rinse should always check.
2, steam pressure
Red lines indicate the working pressure gauge should have, so sensitive and reliable, the trap should be flushed at least once a week.
3, safety valve
Safety valve should seal intact, no leakage; once a week manually (or automatically) emission test, and begin start pressure, opening pressure, reseating pressure and test time, participants, etc credited maintenance log book u, for future reference .
Proceed as boiler water quality requirements of water quality testing personnel under the guidance of class 1 or 2 times sewage, sewage incident not too long, generally no more than 10 minutes.
Sewage should (preferably when shutdown), should be closely monitored sewage water level changes, and pay attention to safety at the time of low load, low pressure, high water level.
Many boilers when sharing a sewage mains, while sewage is prohibited.
1, the normal shutdown
After normal boiler shutdown should generally be reduced boiler load operation, press the boiler shutdown procedure. Actuated pump water to high water level, pressure steam boiler to be dropped after 0.3MPa flushing water table and sewerage operations, and finally close the raft, cut off the power supply control cabinet, wipe equipment, clean up the environment and health, For water, the water temperature should be below after 70 ℃, before proceeding.
2, emergency shutdown
When the boiler operation in the following situations should immediately shutdown:
Furnace water level drops below the minimum water level gauge visible edges.
Increasing water supply and other measures, but digital still continue to fall.
Boiler water level exceeds the highest visible water table level (full of water), the water still can not see the water level.
All water supply system water pump failure or malfunction, not water to the boiler.
Water gauge or safety valve all the failures.
Endanger the boiler element is damaged and the safety of operating personnel.
Combustion equipment damage, or furnace wall collapse and other red-hot boiler structure is a serious threat to the safe operation of the boiler.
Other anomalies endanger the safe operation of the boiler.
Before maintenance work should be well prepared, as before entering the drum interior work, must be of sufficient strength to connect all of the metal blocking plate spaced reliable steam, water, sewage and other operation of the boiler pipes, and the drum manholes and hand holes (boiler shell) is opened, so that air convection period.
After the completion of preparations to repair. Should ensure that the quarterly frequency of boiler maintenance and repair of the year.
Advances in technology to the boiler industry into new and innovative ideas, now the boiler manufacturers boiler are easy targets toward the operation forward, but in the use of the boiler, improper operation or other quality problems still exist, these failures will It is causing the direct cause of the explosion boilers. Therefore, when using the boiler must be in strict accordance with safety practices boiler, security incidents strangled in the cradle.
