steam for a 1 mw 5mw generator
What is the role of energy saving steam for a 1 mw 5mw generators and boiler smoke box: to learn and understand the boiler, the following will be continued, because it is the site of important products, therefore, the need to have a serious learning. And this for us, but also beneficial and harmless, at least, be able to increase expertise on the boiler, and at the same time, can also achieve the proper use of the product, to obtain good economic benefits. 1. What is the energy saving boiler? Energy saving boiler, which is a particular kind of a boiler, specifically, it is the gas generator and boiler combined into one, it is put into the fuel from the grate stoker opening to the combustion, thereby making water vapor phase with seam combined. And, by actively generating a high temperature flame burning system, and further, burned at sufficiently high temperature, to obtain a good combustion.
At 10:00 on September 6 and more, Harbin, a business is the purchase of a new steam for a 1 mw 5mw generator 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.
Indonesia Coal Fired Power Plant
Coal-fired steam units produce electricity by burning coal in a boiler to heat water to produce steam. The steam, at tremendous pressure, flows into a turbine, which spins a generator to produce electricity. The steam is cooled, condensed back into water, and returned to the boiler to start the process over.For example, the coal-fired boilers plant in Indonesia heat water to about 1,000 degrees Fahrenheit (540 degrees Celsius) to create steam. The steam is piped to the turbines at pressures of more than 1,800 pounds per square inch (130 kilograms per square centimeter). The turbines are connected to the generators and spin them at 3600 revolutions per minute to make alternating current electricity at 20,000 volts. River water is pumped through tubes in a condenser to cool and condense the steam coming out of the turbines.
Free supervisory inspection gas steam steam for a 1 mw 5mw generator with a small do? Recently, many customers called to ask small steam boiler there? The problem I think has been plagued by many users, and now I am going to say about you in the end there is no small steam boiler. There are inscriptions specified in the country last year not to produce 0.3 tons less gas steam boiler, because of the very high probability of small vertical steam boiler accidents, often because of lack of water caused by the boiler, to the production of small countries is strictly prohibited after conventional steam boiler, the company's R & D staff spent half a year of successful development of a no-supervisory inspection, small steam boiler for the inspection of small steam boiler, specifications from 0.1 tons to 0.5 tons of gas, oil, gas, this does not require quality and technical supervision boiler inspection and acceptance, and acceptance-free steam generator water volume is less than 30L, according to state regulations, "steam boiler safety technology supervision" within the exemption permits boiler use a range of countries, namely without going through the boiler use permit. Eliminating the need for a year dealing with government departments, more peace of mind. Boiler with full intelligent automatic control technology, as long as someone to fill the fuel inside the boiler on it, if the boiler water itself it will automatically go inside the boiler water, high degree of automation, pressure can reach 10 kilograms, gas for 3 minutes can the steam, fuel gas only three minutes to reach 4 pressure.
