In some areas, the alkalinity of the water source is relatively high. After the combustion of the fuel gas steam induction heating boiler furnace is heated and concentrated, the alkalinity of the pot water will become higher and higher. After reaching a certain concentration, it will foam on the evaporation surface, affecting the steam quality; Under certain conditions, if the alkalinity is too high, alkaline corrosion such as caustic embrittlement in the stress concentration portion may occur. Therefore, the alkalinity of the water should be reduced. In addition, the dissolved solid content is too high, it will also affect the quality of steam, and even cause steam and water to rise. It should be controlled by reasonable drainage.

At 10:00 on September 6 and more, Harbin, a business is the purchase of a new induction heating boiler furnace 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).

2, start

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 .

4, sewage

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.

Third, shutdown

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.

3, maintenance

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.

Industrial steam induction heating boiler furnaces noise reduction method which reduces noise industrial steam boilers What are the methods? As long as the machine will sound during operation, but the decibels of sound, large and small, the sound becomes noise, high-decibel noise will make people feel irritable, headaches, noise on the human body much harm. The cause of serious human endocrine disorders and even mental disorders. This not only does not interfere with people's normal life, but also promote high-efficiency steam boiler operation. Boilers running noisy, more than people can afford decibels. But the high temperature flue gas boiler. If a closed acoustic mode, the device will not be heated and important equipment in the boiler combustion. Industrial steam boilers method of noise reduction: 1 reduction measures boiler pump: Boiler pump noise emitted usually caused by two noises: the noise and the noise flow pump structure itself. Flow emitted noise is periodic pulsatile pumping system at full speed, and high-speed turbulence or cavitation in the pump. Noise generated by mechanical vibrations of the pump structure or vibrations caused by pulsation of the liquid pumps and pipes caused. Pump and motor noise through the pipeline insulation and insulation layer or cover made of a sound-absorbing material, or the partition will be closed to reduce the pump and motor. Vibrating the wall of a noise insulating material may be partially absorbed and a control to reduce transmission of noise. The exhaust gas boiler noise reduction measures: (1) When the exhaust gas, high temperature and high pressure steam is injected to the atmosphere, the jet noise is generated. This noise can be injection orifice muffler, the muffler is attached to the vent orifice; (2) injection orifice muffler structure, pores having a size between 1 ~ 3mm, more than 5 times the center distance hole, open the total area of ​​the holes should be larger than the original area of ​​the exhaust gas of 1.5 to 2 times; 3 in the choice of the exhaust muffler, the muffler should be noted that the exhaust gas temperature and flow rates in order to satisfy the exhaust requirements, maintain a certain strength and corrosion resistance and note the freezing cold steam danger zone overpressure exhaust. 3. The boiler blower noise is mainly from three noise: fan noise caused by air vibration, noise and frictional noise between the rotor body and the operation of the vibration caused by the stator. In general, noise in the air is greatest, typically in excess of the sum of the other. Installation of the fan blades in the muffler, the entire semi-enclosed motor, noise propagation blocking the pathway from the housing, having good silencing performance. Whole-mount power fan may be mounted-enclosure, the entire blower housing can be built, inlet, outlet may hit the cover, and then loaded on the muffler.
