advanced coal water slurry steam boiler

The use of gas advanced coal water slurry steam boiler added to give businesses what benefits? National emphasis on energy conservation increased year by year, which also contributed to the gas steam boiler flourish among industry, under the premise of environmental policies and to efficiency gains, companies are willing to choose both energy-saving, and high thermal efficiency of gas-fired boiler. Gas steam boiler in addition to providing sufficient high-temperature steam, but also can reduce fuel cost by reducing the combustion load input. The use of gas steam boiler will bring any significant benefits, let's take a look. 1, the biggest benefit is the economic use of gas steam boiler can save a lot of fuel costs for businesses, you do not need to spend lots of money to purchase a large amount of coal fuel, just use good cleanliness of natural gas will be able to output enough steam; they also do not We need the fuel storage site, only need to connect to the pipeline. 2, security is well known that natural gas is a very safe and stable, non-toxic and pollution-free, good cleanliness of fuel, liquefied petroleum gas or gas leak after not deposited on the ground, and even cause accidents will burn again. Process gas steam boiler during conveying gas selected gas is the most secure, but also easily found after leakage during use and therefore is the most secure way. 3, convenient gas steam boiler in the use, operation is very convenient, so will much favored by all walks of life. Because the use of all natural gas pipeline, a sustained run without any problems. Eliminating the need to transport coal use and clean-up or stacking cinder and other tedious work. 4. Clean the reason why gas steam boiler in the market to get a high rating, but also because it is clean and not contaminated during use, and does not produce black bottom of the pot, there is no air pollution. Thus, in use, compared to other boiler is the cleanest way.

Xiamen Rui Yi Hotel is available straight left Gulangyu the most beautiful views of the BRIC countries delegations designated top hotels, the best location in the heart of Xiamen, modern trends and classic style pavilions. The hotel features well-appointed room service, fashion and superior restaurant, bar, meeting rooms and a gym, swimming pool and other recreational facilities, people feel contented and comfortable. Projects and programs as Xiamen Rui Yi Hotel Xiamen City landmark hotel building, attaches great importance to environmental protection philosophy, which party fast boiler manufacturing philosophy coincide. In late 2016, the two sides signed an electric advanced coal water slurry steam boilers for hotel supplies disinfection work, since the electric steam boiler, any security incidents never happened, Rui Yi Hotel ensure normal operation.

Coal to natural gas operations bunch of factors that vertical pressure advanced coal water slurry steam boiler energy consumption indicators of the country are carried out in a big way, the choice of vertical steam boiler, to a large extent minus the pollution of powder, together with nitrogen oxides and other dangerous gases the press has been discharged. Energy consumption indicators is an important rule to measure vertical steam boiler, to discuss the next bunch of factors under pressure vertical steam boiler energy consumption indicators. By analyzing the relevant departments, vertical steam boiler heat loss occurs mainly includes two aspects: the proportion of non-standard sufficient combustion air with exhaust heat loss. Weaken the heat loss can be retrofitted in the vertical steam boiler chimney terminal latent heat of re-use form, or in the selection of better boiler system FGR. Combustion air ratio is not sufficiently decomposed inappropriate criteria: ordinary vertical ejector-type steam boiler burner based, air-fuel ratio can not be formed in the active mobilization. More vertical steam boiler based on a mechanical blower burner, air-fuel ratio due to the following standards several factors: air-fuel ratio standard comprises two situations: when oxygen is excessive, the excess will be an infinite cryogenic air by heat conduction, caused by rising energy vertical steam boilers, low energy consumption vertical steam boiler index; when there is insufficient oxygen, there will not be sufficient to ignite the situation, leading to low energy consumption indicators vertical steam boiler.

Main advanced coal water slurry steam boiler temperature abnormal phenomenon of how to do 1, main steam temperature anomalies alarm. 2, the rapid variation of the main steam temperature, a secondary damper frequently significantly reducing water operation. 3, starting superheat outlet steam separator above or below normal. 4, if the steam with water, the unit will water shock occurs. 1 reason, the fuel and water supply imbalance, the separator outlet temperature abnormality. 2, coal combustion conditions change or affect, such as excessive load lift; and pulverizing mill administration system abnormality stop; means automatically increase or decrease the failure rate is too large amount of wind and the like. 3, the central flame furnace changes, such as the bottom seal damage, W and inadequate flame downstroke. 4, the control failure by warm water, warm water flow rate reduction is abnormally reduced or increased. 5, feedwater temperature mutation. 6, does not match the wind coal. 7, the secondary combustion heating surface. 8, furnace coking or fouling seriously. 9, heating surface leakage squib. 10, flue gas damper opening degree is not normal. 11, coal sudden change occurred. 12, the uniformity of the powder feeding substantial change occurs. 1 process, failure caused by unit coordinated coal - water ratio should be immediately released coordinate offset, in accordance with the current load demand, with reference to the start of the steam superheat separator, and adjusting the amount of fuel corresponding to the amount of water, with one, two main desuperheating water rapidly steam temperature control in a normal range; when the coal - water ratio should avoid imbalance after coal and water while adjusting; when coal - water ratio is adjusted to further adjust the load after a relatively stable; contact maintenance processing timely. 2, when the water supply system fault condition occurs a significant disturbance furnace should pay attention and automatically coordinated working conditions, so as not to manual intervention, when not working properly coordinated and automated, should be manually adjusted, stable water flow, referring to separation according to the water flow steam superheat, the adjusted amount of fuel, with a secondary spray water rapidly controlling the main steam temperature within the normal range; contact maintenance processing timely. 3, due to rapid changes in load caused by the load change rate should be adjusted; load change caused due to protective operation or the like caused by heat load to be quickly adjusted to maintain the boiler pressure of the main steam stability. 4, by warm water automatic dysregulation, should be appropriate Save warm tone is switched to the manual may be an intermediate point of the feedwater control system be corrected for temperature if necessary, or the feedwater to switch control to manual control, due to lower lifting and lowering the load speed to prevent steam temperature, promptly contact a service process. 5, the boiler furnace cause severe fouling and coking of the main steam temperature anomalies can be corrected by an appropriate degree of superheat outlet steam separator start, adjust, and in a timely manner and the furnace heating surface sootblowing. When the platen superheater sootblowing or superheater outlet temperature is still above normal and a secondary reducing water damper fully open, to check the furnace and the combustion air distribution system is normal, the checking process to reduce still overtemperature unit load. 6, flue gas damper adjusted to an appropriate opening degree. 7, if the bottom seal after losing back to normal immediately. 8, to strengthen the turbine expansion, differential expansion, axial displacement of the shaft vibration and bearing temperature monitoring, if abnormal, the process according to the corresponding regulations. 9, after the above measures, if invalid, should immediately drop the load process. 10, in front of the main steam temperature main steam 50 ℃ drastically reduced within 10 minutes, should an emergency stop.

Coal utilization - Coal combustion | Britannica

Coal-water slurry fuel (CWSF) normally consists of 5070 percent pulverized or micronized coal, 2949 percent water, and less than 1 percent chemicals to disperse the coal particles in the water and prevent settling of the coal. The slurry is finely sprayed (atomized) into a combustion chamber in a manner similar to that used for fuel oil.
