The characteristics of internal circulating fluidized bed boiler

The internal circulating fluidized bed boiler (ICFB) efficiently co-combusts industrial waste, biomass fuel and coal, provides steam or hot water, and sets new standards in limiting SOx and NOx generation. In addition to the characteristics of general CFB boiler, the internal CFB boiler also has the following special structure and characteristics:

1. The internal CFB boiler has buried pipes, which can increase the heating area and regulate the temperature in the dense area.

2. The internal CFB boiler has a large area of air distribution bed, so that the boiler has more heat storage, which is conducive to fuel combustion and burnout, and provides a congenital condition for a wider variety of coal adaptability;

3. The internal CFB boiler has a large cross-sectional area of the furnace, the flow rate of flue gas is low, which can improve the primary combustion rate of fuel, reduce the wear of the furnace, reduce the power consumption and energy consumption;

4. The wind arch composed of secondary air can supply oxygen and disturbance on the one hand, and on the other hand, can lengthen the combustion time of coal, which is conducive to coal burnout;

5. Water-cooled membrane wall of the cyclone separator, effectively prevent high temperature coking and center cylinder bias, which improves the efficiency of the separator;

6. Porous and controllable feed return valve makes the feed return reliable, even if the feed return has a coke block, since there are a lot of feed back port, there is no need to immediately stop the furnace, the user can stop the furnace when it is available for them to clear the coke.

7. Tail flue gas duct patented technology: water cooling furnace roof and chevron water cooling flue gas duct, can effectively solve the roof and smoke wall collapse and leakage of ash or air, which improve the environment of the boiler room.

2, oil consumption is relatively stable. The first three quarters, apparent consumption of oil increased by about 3.4%, growth was flat with last year.

3, rapid growth in natural gas consumption. The first three quarters, the apparent consumption of natural gas increased by about 16.7 percent, the growth rate down 0.8 percentage points over the same period last year.

4, the rapid growth of electricity consumption. The first three quarters, total electricity consumption grew by 8.9% year on year, the growth rate increased by 2 percentage points over the same period last year, the highest six-year high.

Second, continue to promote energy transformation.

1, continue to optimize the structure of power installed. Clean energy power generation capacity in the first three quarters, hydropower, nuclear power, wind power, and solar power together, the total installed capacity of 36.4%, 1.4 percentage points over last year; clean energy generating capacity grew 8.9%, higher than the growth rate of the thermal power by 2.0 percentage points .

2, electricity consumption structure was further optimized. The first three quarters, the four energy-intensive industries the proportion of electricity which fell 0.5 percentage points, tertiary and residential proportion of total electricity consumption increased by 1 percentage point.

Third, the quality of energy supply and gradually increase.

1, to coal production, ensure supply, stable prices marked success. The first eight months, the cumulative excess resolve the coal production capacity of about 100 million tons, completed 67% of the annual task.

2, resolve to further promote coal overcapacity. Relevant local and enterprise-wide combing less than 300,000 kW coal units, investigation of energy efficiency and environmental non-compliance unit to implement the 2018 coal industry, eliminate backward production capacity goal.

Fourth, make up the short board energy projects to accelerate.

1, natural gas security of supply capacity significantly enhanced. Natural gas pipeline network interconnection, gas storage facilities, gas prices and other work to accelerate the merger.

2, energy Huimin construction speed. Clean warm northern steadily. In two batches to arrange 12 billion yuan central budget for investment, focusing on upgrading rural power grids "Three Tri-State area," the depth of poverty-stricken areas.

3, project reserves of energy make up the short board to speed up the implementation of the work.

Five pilot power system reform in full swing.

The provincial power grid transmission and distribution tariff reform to achieve full coverage. Cross inter-provincial renewable electricity spot trading further promote the pilot.

Sixth, the energy efficiency of the sector, improving overall efficiency.

The first eight months, gross profit increased by 25.1%, accounting for 17.8% of industrial enterprises increased by 5 percentage points over the same period last year.

Steam boiler wear and electric test pump DSY Henan fast boiler's 5000 kg coal fired steam boiler small series with you about wear and DSY electric test pump wear is one common steam boiler heating surface defects, boiler heating surface is arranged in the boiler the furnace and the flue, in particular a heating surface in the steam boiler flue vertical tail, by the long brush smoke, soot in the flue gas so that the wall heating surface wear thinned, so that heat from the flue gas scouring wall ironed a phenomenon known as wear and tear. Flow rate, the concentration of soot in the flue gas and the hardness of the tube bundle arrangement such factors as the wear rate of the heating surface of the steam boiler and the flue gas is related to the flow rate of flue gas wherein the greatest impact on the wear of the heating surface. Experimentally measured, proportional to the cube of the wear rate of the heating surface tubes and the flue gas velocity, it is necessary to effectively control the flow rate of flue gas. Leakage of the furnace wall, a partial wall flue ash, convection heating surface partially severe slagging will cause a partial flue gas velocity is too large, so that the heating surface tubes local wear increased, further, when the soot blowers work failure, high pressure steam steam heating surface tube will blow erosion, so that the wall thinning. Heating surface tubes often wear area is: cool ash, burner, bullnose, and close to Manhole sootblowing waterwall tube aperture; a lower portion of the flue gas before the steering tube heating surface vertical chamber; vertical tail horizontal heating surface portion of the second row of three tubes of the flue, the lower portion of the second three tubes, tube support edge portion of the clip, close to the furnace wall side of the rows of tubes and the individual tubes and the like projecting tube rows. Heating surface wear reduction methods are: to reduce boiler load, reducing flue gas velocity; burning coal quality, reducing the content of fly ash in the boiler flue gas steam; change bundle arrangement, a staggered arrangement to the line arrangement; Clear slagging and blocking flue ash, flue gas flow area increases; leakage reduction furnace wall; the installation of a shoe or the spoiler like. Abrasion test on the electric pump plunger hole set DSY electric test checking pump plunger sleeve (1) Check the DSY type. If the pump DSY electric test has passed the test on sealing ST-990 or the tester 3,375,375, the plunger sleeve is available. If the leakage is large, it is necessary to replace the plunger and plunger sleeve. (2) using the burr, coke, and high-expansion magnifying glass to check the amount of deformation of the bore. When the metering orifice is damaged, DSY i.e. electric test pump is not working properly. Do not attempt to clean with a wire, plug, etc., should be cleaned with a solvent. (3) Check the fuel oil channel as well as choking loose plunger sleeve for cracks. (4) Check DSY electric test pump plunger sleeve surface endless belt black area and Degree how damage flatness. Some electric test pump head end of the barrel nozzle sump has been canceled.

And today we work together to explore. Gas-fired steam boilers and coal-fired steam boilers on the market each accounted for half of the country, showing potential rival, but in the long run, gas steam boiler will obviously be the only dominant market. Do not believe, look! 1. Purchase costs: gas boiler is evident in the technical and auxiliary facilities are far ahead of coal-fired boilers, and it is equipped with a special gas burner. 1 steam boiler tonnage, for example, than the price of coal-fired boiler gas boiler on high about 30%. 2. Construction costs: The costs mainly from the boiler room. Because the corresponding auxiliary equipment more coal-fired steam boilers, so the boiler room construction funds have more. The gas boiler auxiliary facilities require little or automatic control and operation, and automatic alarm and automatic protection, not only save building costs, but also safe and reliable; Also connected to the gas pipeline, the burner will automatically supply gas can effectively save costs staff. The coal-fired boilers because of the need of coal on the program, so it needs some staff payroll. 3. Fuel cost: around this by looking at the actual specific fuel price can be clearly seen. The fact is that the amount of gas than burning coal per hour to be much more. 4. environmental costs: in the need to protect the environment, review the current coal-fired boiler more strict. The gas steam boiler due to the operation of the economy, environmental protection and energy saving, as well as government policy to encourage more and more widely used.
