3ton steam generator
CFBC boilers are generally more economical than AFBC boilers for industrial application requiring more than 75 – 100 T/hr of steam. For large units, the taller furnace characteristics of CFBC boilers offers better space utilization, greater fuel particle and sorbent residence time for efficient combustion and SO2 capture, and easier application of staged combustion techniques for NOx control than AFBC 3ton steam generators.
What needs to pay attention to low-carbon transformation of the boiler there? Compared to ordinary low-carbon boiler boiler, it is much more environmentally friendly, so I chose to use a low-carbon economy to be more environmentally friendly boiler, then, to use the technical transformation of the boiler low-carbon, low-carbon transformation that the boiler when what ? attention to the needs of today it Yuyao Kai large 3ton steam generator boiler manufacturers are concerned that low-nitrogen transformation of those things: 1 gas burner ignition fails the second consecutive time, should stop to check the gas supply system, the burner has occurred normal circuit wiring is correct, after the lifting of the fault before restarting the burner. 2. The supply line is prohibited or metal rod with a wrench percussion, friction, to avoid static electricity or sparks, causing a gas explosion. 3. In the non-gas manifold or pipe smoking, etc. flange, welding, cutting and other illegal operations. 4. prohibited any open flame test next to the pipeline and valve block and pressure regulator, to avoid a major accident. 5. In the gas supply line, is carried out evacuation, but the residual wall gas or liquid droplets, in case, electrostatic sparks and flame also cause fire and explosion. 6. When the air supply has the same period, and when disassembling valve failure, it shall be first distal manifold valve, then the valve to the manifold to the total length of tubing in which the gas is vented before it can be disassembled with the valve service. 7. prohibit the use of non-explosion-proof electrical power tools in the field. Leak valve 8. A device must be checked before use. 9. Before burner start, the supply pressure testing must be done to check for leaks, after confirming normal, then a simulation run. 10. When the burner is not used to inform the customer off power supply main valve and the main switch. 11. Not recommended for debugging night burning machine. 12. At the end of commissioning, to organize training of operating personnel to use the operating direction, establish operating procedures, if necessary. These are some of the issues of low-carbon transformation of the boiler should be noted that, in order to prevent danger, should strictly follow the precautions execution, where the checks have checks in place, there can be no negligence, to complete the renovation project of low-carbon boiler.
Steam boiler three indicators and characteristics of magnetic drive fast boiler company Henan ready before the start of a centrifugal pump with small series to introduce steam boiler three indicators and characteristics of magnetic drive centrifugal pump Before you start to express the characteristics of the steam boiler, usually steam boiler capacity, parameters, characteristics such as reliability and economy indicators. In this example and several characteristic index defined steam boiler: 1, evaporation and steam boiler heating power: the size of the steam boiler capacity is typically rated represented evaporation. Rated evaporation refers rated parameters (pressure, temperature), under the conditions of burning design of the fuel and to ensure that the design efficiency, continuous operation should achieve maximum evaporation amount (per unit time steam production), should this be the rated output or evaporation plate, by the symbol "D" indicates the unit is t / h or kg / s. steam boiler plant and may also be supporting the thermal power turbogenerator, i.e. kw or mw represented. From the viewpoint of energy conversion of view, the ability to heat a steam boiler with a rated heat input, i.e., rated thermal power is represented by the symbol "Q", the unit is kw.Q = D (iq-igs) = D △ i, formula iq for export steam specific enthalpy (kj / kg); ig of feed water specific enthalpy (kj / kg) to different steam, water evaporation parameters is compared or additive, may be the actual steam evaporation D terms. "standard evaporated vapor amount" Dbz ", producing a predetermined amount of heat absorbed per 1kg no standard steam is 2680kg, so Dbz = D * △ i / 2680t / h or kg / s. and the hot water boiler are denoted by thermal rating the size of the boiler capacity, the symbol "Q", in units of MW, Q = G (is - ih) × 10 ?, where G is the amount of hot water boiler (kg / s), ihs, irs boiler out saliva enthalpy (kj / kg) .2, steam or hot water: parameter steam boiler steam production means at the outlet of the rated boiler steam pressure (gauge pressure) and a temperature of the boiler producing saturated steam, generally designated vapor pressure, by the symbol "P", in units of MPa, for the production of superheated steam boilers or hot water, and the need to indicate pressure steam or hot water temperature, the temperature to whom Economizer fingering water temperature, meaning that when the drum into the boiler without economizer temperature water temperature indicated by the symbol "t", the unit is ° C. Preparation ① Check magnetic drive centrifugal pump start before magnetic drive centrifugal pump connection bolts and anchor bolt without loosening .② pipe connection inspection is appropriate, whether the center of the pump and driver in processing temperature, cryogenic liquid pumps, pipe expansion, contraction may cause axial disorders, bite, etc. Therefore, the flexible pipe joint requires the use of direct coupling and centering etc. ③ small, when stopped, no major changes in the centering of the pump and the motor room temperature magnetic pump: while large, high temperature magnetic pump run and stop in very different axis, for the correct centering generally require warming to operating temperature after running or stopping the pump, to ensure rapid re-centering of the axis of both rotor consistency to avoid vibration and pumps the cleaning nip .④ piping must be first cleaned of foreign matter before running pipe, welding slag, Never push objects off the pump body human. gauge mounted on the screen before and after inhalation tube, in order to monitor the operation of filtration The blockage .⑤ disk drive. Before starting remove the coupling, rotation of the rotor by hand if there is abnormal, and the motor alone test, check if it is consistent with the rotational direction of the pump. Joint rotated by hand, can be found in between the pump impeller and the casing without foreign body, the disk drive should be uniform weight, no noise in the pump.
Tongchuan City, Shaanxi Province is located in Fenwei plain, it is China's major coal producing area, the unique geographical location determines the Tongchuan coal energy as one of the main economic development. Tongchuan coal to bring rapid economic development, but a large proportion of heavy industry, atmospheric pollution and other issues are very serious. "Winning Blue Sky Battle three-year action plan" published this year, Fenwei plain was a key governance areas. Coal City is not achieved coal, coal is not coal, promote clean heating, Tongchuan City is a serious problem.
Tongchuan party secretary said: "This year Tongchuan 4905 ex situ poverty alleviation relocation of the masses of resettlement housing has been fully completed and turnkey, the actual stay 3763, is a large-scale relocation of mass arrival of new homes in the first year."
After a preliminary investigation, Tongchuan City to improve people's livelihood and environmental protection together, launched a "warm life, warm hearts and minds" of warm winter action. Based on the concept of local conditions, it has been completed in 40 of the city's centralized settlements, reduce operating costs, clear charges. Mastery of natural gas household heating settlements, natural gas boiler wall encouraging people to self-heating; central village of rural resettlement and scattered resettlement households, encourage and guide them to use electric heating and cleaning of heating equipment. All use of clean heating devices are available to the masses 1000 yuan subsidy.
Clean heating, an impact on the masses warm winter, a relationship with Blue Sky Battle Action Plan. It is understood that the city of Tongchuan coal-fired boiler to achieve a global "clear" in 2017. 2018, Tongchuan City by town gas central heating and household heating, rural households in accordance with the appropriate air dispersion of the gas, should the electric power, should be hot is hot, use clean coal coal should guide the masses to reduce the amount of bulk coal use, and the use of clean energy and the masses of poor people winter heating subsidies. Currently Tongchuan City, completed a total clean energy alternative to coal for 27,897, of which 25,196 coal to electricity, coal to gas 2701, the city's clean heating rate of 82%, the basic realization of the coal city does not burn coal, coal is not coal.
According to Eco-Environment Department data show that 11 cities Fenwei plain mean concentration of PM2.5 in October this year to 48 micrograms / cubic meter, down 7.7% year on year. The lowest average concentration of PM2.5 is Tongchuan city, is 38 micrograms / cubic meter.
