china atmospheric hot water boiler manufacturer

Improvement: condensing boiler after pickling, passivation must be rinsed, since the passivation more stringent requirements, thus rinsing process must be strictly controlled concentration of total iron ions. After rinsing is complete, iron ions tested meet the requirements, the PH value immediately adjusted to strongly basic, and the passivating agent is added, warmed passivation.

WNS Oil Fired Hot Water Boilers have reached the first-rated level of the world in the key technical aspect. We adopted German technology and won the bid of world bank GEF efficient and environmentally friendly boiler sub project. WNS oil fired china atmospheric hot water boiler manufacturer for sale fuel can be use Heavy Oil, Light Oil, Residual Oil, etc.

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