SZS series gas-fired superheated steam boiler project for heating industryXinzheng Heli Thermal Co., Ltd. is a company specializing in heat energy production and central heating supplying, providing heat source for winter heating for people in Xinzheng . Facing the increasingly serious environmental problems, Xinzheng Heli decided to respond positively to the "coal to gas" policy, using clean energy natural gas as boiler fuel and introducing high efficient gas-fired boilers to replace the original coal-fired boilers. For this, Xinzheng Heli Thermal carried out an open bidding. After competitive bidding and strict selection,ZOZEN defeated other competitors and won the bid with its comprehensive corporate strength. The winning bid was ZOZEN energy saving and environmental protection product - SZS series condensing gas-fired superheated steam boiler (3 sets of SZS75-1.6-Q). The furnace and the front and rear walls of this series of boilers adopt membrane water wall structure, and the airtightness is good. The large furnace design is combined with an advanced ultra-low NOx burner to ensure sufficient fuel combustion, controlling the NOx emissions below 30mg/m³ and the thermal efficiency up to 98%. At the same time, the boilers adopted the flue gas recirculation technology and were equipped with economizers and condensers at the tail of the boiler flue, which not only followed the concept of energy conservation and environmental protection, but also met the thermal energy requirements required by the project.
Although the fuel of 58MW circulating fluidized bed fired industrial hot water boiler is also coal,but it adopts CFB circulating fluidized bed combustion technology,and mixture of gas and solid, and the fuel particles and circulating combustion, the fuel particle residence time in the furnace is lengthened, the combustion efficiency can reach 97-99%. The boiler thermal efficiency up to 85%, higher than the national standard of 15-20 percentage points, has remarkable energy saving effect and economic benefits. In the society to reduce the energy waste, but also to reduce dust emissions, the social benefit is great.
In response to the state-assigned air quality improvement objectives and environmental supervision central feedback coal-fired boilers environmental pollution rectification program, Kang County, Gansu Province based on "government-led, relying on real responsibility, Take Measures to proceed with" principle, accelerate the burning of remediation work out of the coal boiler, and to develop the following measures, at present, reconstruction activities are being actively promoted.
A: a comprehensive investigation, the establishment of accounting. For urban areas, towns, Kudo industrial parks all coal-fired boilers to conduct a comprehensive diagnostic investigation, a total of investigation and the use of the boiler 31 enterprises, a total of 38 boilers, electric boilers and removal of fuel two boilers, coal-fired boilers county a total of 36, including two sets of 20 tons of steam boilers, coal-fired boiler pressure 4. In the diagnostic process, the situation boiler location, type, number of units, the tonnage, use, carefully verify the age and so on, and sort out the summary, so that a boiler does not leak, the device information is not a shortage.
Two: to strengthen publicity, and create atmosphere. Through new media, focus on advocacy, government circulars issued, will be held to promote the government leaders in charge of on-site investigation led mobilization and other forms of media offensive formation, multi-level multi-angle carry out various forms of publicity and education remediation phase out coal-fired boilers, each guide society personnel support and participate actively promote the use of coal-fired boiler units understand the situation, to speed up the phase-out of coal-fired boiler renovation.
Three: supervision of interviews, results-oriented. Person in charge of the county Bureau of Quality Supervision led, in-depth coal-fired boiler unit, for the slowness, lack of knowledge, waiting to see the business units and enlighten them with reason, and emotionally moving. With the responsible persons of the two job interviews lag to not be one of them out of the situation Reconstruction of boiler in accordance with national policy requirements, on-site recovery boiler registration certificate and ordered deadline to be removed or modified.
Kang mentioned standard by the transformation, step out, closed down closed down, to gas and electricity from coal to supervise a number of measures to actively promote the elimination of remediation coal-fired boilers. Currently the county out of 29 coal-fired boiler units, of which 15 units destructive demolition, stop burning close 12 stations, two mentioned standard transformation. The remaining seven out of focus on remediation plan included in this year, the county continues to promote this work, and to call on the unit enthusiastic, standards do not fall, the team leave, determined to complete the end of October this year, the county and below 10 tons of steam coal-fired boiler work all clear.
Note the boiler operating at low load range of the boiler load change is normal: coal-fired boilers typically 70% -100% of rated evaporation; oil furnace is 60% -100% of rated evaporation. Below this range is the low-load operation. The main problem is the low-load operation, poor combustion stability, we must prevent the fire and explosion at the furnace, natural circulation boiler must also consider the safety of the water cycle. Thus, when low load operation, the boiler attention to the following aspects: 1, should be as low-load burning high volatile coal. When low volatile coal, during unstable combustion, combustion should be put into the ignition oil gun, in order to prevent possible fire. 2, input at low load the burner should be more uniform, the number of burners should not be too small, which is good for both combustion stability and prevent individual parts of the water circulation is not normal. 3, the speed should be slow changes in the load, and adjust the air volume. Note that maintain a steady wind pressure, which should be the primary air volume is too large. Burner input and deactivation operation should be slow. 4, oil-fired boiler during low load operation, since it is difficult to ensure the combustion quality of oil, should be taken to prevent droplets caused by the re-ignition of unburnt flue tail. 5, low load operation, to minimize the use of desuperheating water (mixing desuperheater), but it should not be heated Save the door shut. 6, low load operation, the exhaust gas temperature is low, the possibility of low temperature corrosion is increased. Therefore, they should put warm or hot air recirculation.
