steam locomotive boiler construction
More economical steam steam locomotive boiler construction can play a role in energy saving produced by the steam boiler is high-pressure gaseous, during use, a large amount of steam can be generated, so the use of the pressure vessel, in which a related aspect there is a certain provisions, whether used or installed must comply with some aspects, and apply the relevant evidence, but also to accept the annual inspection. This boiler used in the printing and medical care more. If the hot water boiler is produced, so it is not pressurized container, are often used in our lives, is relatively small in terms of investment, use of the process, management costs are very low, of course, will be more secure. Some schools or community-related, may also be related to the use of this method of heating water, relatively speaking, it will be more convenient. Steam boiler in the structure, allowing fuel to burn more fully, and in the process run more stable, can really improve efficiency, which would allow users to better reduce costs, the whole of it will be more use more protection. Many places are in use, can play a role in energy saving, and relatively more economical, so that it can use real protection. From the analysis of the specific works, the use of the process, the main heating device to release heat, then by a certain conversion, a large amount of steam, and the steam trap correlate. Use of the process, increasing the temperature of the steam is then able to reach the required temperature. This works, this works can improve work efficiency, and truly play a better role. Structure and principles of steam boilers, this area will affect the future use, advance the understanding of the relevant circumstances are, and have the knowledge of the whole of use, which for us will have more benefits, so be sure to do ahead of time to consider. Before purchasing equipment, we have to confirm in advance that these circumstances device, so that it can ensure that the specific choice of fruit, you can also make use of the process more smoothly. Different devices are not the same in construction and principle, let me use the process, there will be different results. Structure and principles of steam boilers is what, to correctly do know these aspects, then the future in the selection process, will have a corresponding basis for these people to purchase provides choice, so we have to advance to do a good understanding.
Noise reduction method for Gas-fired Steam Boiler
Gas noise reduction methods for gas-fired boilers are mainly sound insulation, sound absorption and noise reduction.
At 10:00 on September 6 and more, Harbin, a business is the purchase of a new steam locomotive boiler construction 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.
