Electric 6 ton coal boiler commercial cheap laos advantages: electric boiler because of its low consumption, convenient, more and more people are welcome, so that people no longer have problems because of coal, causing a lot of unnecessary trouble, electric boilers do not understand what advantage allows electric boiler You use the electric boiler to join the ranks of it? Below these advantages, it must give you enough reason to use an electric boiler.
Select the appropriate 6 ton coal boiler commercial cheap laos fuel and combustion forms: the most consumed fuel in use is the boiler, energy-saving measures to do first of all have to start from the choice of fuel. In the current economic conditions, there are three main boiler fuel, namely the solid fuel, liquid fuel and gaseous fuel, three different heat generated by the fuel which is not the same, the degree of harm to the environment is not the same. On the whole, in terms of heating fuel gas quality or environmental protection has a significant advantage in the choice of fuel should be preferred. Heating boiler in some systems because of the influence the production process and the fuel supply capacity, the choice of gaseous fuel is also subject to certain restrictions. In the selection of fuel, because the high cost of this choice of fuel in the boiler heating costs tend to be higher. Is more feasible briquettes may be employed, it will be used after vaporization, the residue after burning so that less amount of the exhaust gas is small too heavy discharged from the combustion, and the combustion heat value of the coal after vaporization is relatively high, so the use of more cost-effective in the heating boiler.
Five combustion characteristics of gas combustion in The five main combustion characteristics of gas combustion of Fangkuai environmentally friendly gas-fired 6 ton coal boiler commercial cheap laos in recent years, many cities frequently occur haze, which has aroused wide concern and heated discussion in the society. China is in the period of energy structure adjustment, the task is imminent, the situation is also very serious. The energy-saving and environmental protection gas-fired boiler of Fangkuai boiler is the time to show its good energy-saving effect and excellent environmental protection ability. More and more favored by enterprises. Next we analyze its advantages from the combustion characteristics of gas fuel. Gas fuel is an efficient, clean energy source, its ignition temperature is relatively low, flame can spread rapidly to each furnace. Local, rapid combustion, easy to achieve automatic gas transportation, mixing, combustion process, mainly have the following characteristics: (1) pollution is almost zero combustion characteristics, plus basically will not produce ash, The nitrogen and sulfur contents are much lower than those of coal and oil fuels, and the amount of dust contained in the flue gas produced by combustion is also very small, which is very conducive to the protection of the environment and is basically a pollution-free combustion mode. Even the areas with the strictest environmental protection requirements can be safely used, at the same time, gas fuels are piped to transport, do not produce ash, transport, storage will not occur in the process of harmful gas leakage, dust pollution and noise pollution. (2) it is convenient to adjust the combustion. The way of transportation of fuel gas is pipeline, which can adjust the gas consumption, adapt to the change of load quickly, and realize low oxygen combustion by adjusting the valve and air valve. Thus improve the thermal efficiency of the boiler. (3) good workability. Compared with oil fuel, gas fuel is piped and supplied directly, eliminating oil storage tank, daily fuel tank and other components. In particular, compared with heavy oil fuel, save heating, heat preservation and other links. Gas system is relatively simple, operation and management is relatively convenient, easy automation. (4) easy to adjust heat. Combustion liquefaction When LPG is added, adding part of the air can not only avoid part of the explosion range, but also adjust the heat generation. (5) Gas fuel also has some shortcomings, when mixed with air to a certain proportion, it will form explosive gas. And most of the components of gas fuel are asphyxiating or toxic to humans and animals, so the safety requirements are very high. The Fangkuai boiler attaches great importance to the safety of energy-saving and environmental-friendly gas-fired boilers, and strictly guards the quality level during production and commissioning. There will be no safety accident as long as there is a code of practice in the process of use. At the present stage, China is vigorously promoting the coal-to-gas project to return the people to a blue sky. . Enterprises have responded to national policies and assumed social responsibility. Warmly welcome you to our Fangkuai boiler to buy energy-saving and environmentally friendly gas-fired boiler.
At 10:00 on September 6 and more, Harbin, a business is the purchase of a new 6 ton coal boiler commercial cheap laos 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.
