How to determine the purchase of energy-efficient gas large industrial boiler exporters in da nang is not a choice of energy-efficient gas boiler, as opposed to ordinary gas boiler, saving fuel and input costs are extremely significant. Use energy-efficient gas boiler, to achieve full combustion of fuel, not only improve fuel efficiency, but also improve the overall thermal efficiency of the boiler. In the other parameters the same, the same amount of water is heated to a certain temperature, the higher the amount of fuel used in combustion efficiency of the boiler efficiency is much lower than the low gas boiler. Environmentally friendly gas-fired boiler is the government whether to allow the new premise, and energy-saving boiler, energy consumption is directly linked to the economic interests of a more direct relationship with a person of the boiler. How to determine whether your purchase of energy-efficient gas boiler, you can determine two things: 1, whether the fuel is completely burned for energy-efficient gas boiler, the fuel combustion in the furnace is very full, high combustion efficiency. In the other parameters the same, the same amount of water is heated to a certain temperature, the amount of fuel used by the boiler with high combustion efficiency much lower than the efficiency of the gas boiler is low, which reduces the cost of purchased fuel, significant energy saving effect . 2, the exhaust gas temperature is high or low on energy saving type gas boiler, the flue gas temperature after combustion of fuel is not too high discharge temperature ,, temperature is too high, the heat released is not supplied described all of the water in the boiler, which heat is as the exhaust gas discharged into the air. Temperature is too high, the thermal efficiency of the boiler is reduced, the energy saving effect will be reduced.
Gas-fired steam large industrial boiler exporters in da nang blowdown processing techniques which use any boiler blowdown must be, otherwise it will affect the normal operation, slowing the life of the boiler: the definition of sewage: In order to meet the standards of boiler water, impurities in the water must be controlled within a certain range, this requires removal of salt from the boiler, the boiler water higher alkali content and depositing in the bottom of the water, sludge-like precipitate and loose, this process is known as blowdown. Sewage Purpose: Excluding these sediment discharge, will affect the quality of steam, but also the inner wall of the boiler scale build-up, resulting in poor water circulation normal operation, the impact of the boiler. Thus, the formation of impurities to be discharged into the boiler, to ensure that the salt content in the range of the allowable water boiler, which is the object of the sewage. Sewage mode: continuous blowdown also called surface discharge. This sewage uninterrupted manner i.e. the maximum concentration of the boiler water from the boiler water a boiler discharge surface layer, which role is to make the salt content of the water and alkalinity reduction furnace, otherwise, excessive concentration of boiler water steam quality will be affected . Also referred to as sewage regularly or intermittently bottom blowdown discharge is intended to enable the accumulation of slag in the lower portion of the boiler and the precipitate is excluded. Although the duration of each periodic discharge is not long, but it has a strong ability to discharge pot precipitate. 1, the sewage water level in the boiler to be at low load is slightly high vapor pressure and good low load, the boiler water circulating slowly, resulting in easy accumulation of dirt in the drum, the bottom of the collection tank, and the high vapor pressure: Note sewage high blowdown flow, to facilitate the discharge of dirt. Thus, when the boiler blowdown water level should be maintained in order to operate the sewage at around 60%, it must be set when the sewage someone to operate closely monitor changes in the water level to prevent water shortages. 2, the drain valve should open each short intermittently discharge opening quick-closing speed, disturbances caused by dirt slag, thus repeated several times, the precipitate was suction rely possible to quickly meet at outfall, then concentrated discharge. To control the right time, not too long, usually once a sewage must be in the 30s of the time. If the discharge time is too long, the water content of soil furnace will be gradually reduced, so the effect of variation not only sewage, emissions have increased, not only a waste of energy, but also affect the boiler water circulation, and even burst pipe failure may occur. 3, the observation of a given row Expander sewage after the steam outlet, must touch the outfall temperature, and view given row Expander air outlet, in order to determine whether or not to confirm the drain valve is fully closed. Ruoyin debris stuck in the spool of the leak can be re-opened after a rapid close, if the issues shutting the valve wear and difficult, should strengthen surveillance, arrange repair or replacement as soon as possible, at the same time, should be prepared to shift on the record corresponding record, for subsequent inspection.
Conditions of use large industrial boiler exporters in da nangs and high temperature denitration device condensed water use benefits: boiler, which is widely used now, but, it is the site of important product and main keywords, so, based on these two points, the understanding of the boiler and understanding is necessary, and this for all of us, is worthwhile, because you can use the correct operation of the boiler, to obtain the desired results. So, the next will immediately carry out this work, improve learning efficiency. 1. In which case, it is necessary to use a denitration apparatus or device on a boiler? According to the relevant requirements, the boiler power is at least 65 tons, is necessary to use a denitration apparatus or device. However, in some places, its more stringent requirements, as long as the nitrogen oxides is not up, then, you must use the denitration devices or equipment, whether it is only a few tons of small boiler or large boiler.
To speed up solving air pollution prevention and control Liaoyang key and difficult issues, Liaoyang city government combined with the actual circumstances of the sky to win the Battle of implementation. Details are as follows.
1, promote clean heating. To proceed from reality, should the electric power, gas should the gas, the coal should be coal, should be hot is hot, warm winter to ensure the safety of the masses. In strict accordance with the "Notice on
2, control total coal consumption. According to energy-saving emission reduction Work Leading Group Office of the City "on the issuance of Liaoyang control total coal consumption program of work (2018-2020 years)" (City of Liaoning Office Savings Fa  No. 3), the city's total coal consumption do control. Vigorously for shutting down energy consumption, safety, environmental protection and other 300,000 kilowatts coal-fired units of non-compliance, capacity indicators for shutting down the unit, allowing the transaction or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units. In 2020, the city's coal accounts for the proportion of total energy consumption control to 58.6% or less.
3, in-depth implementation of coal-fired boiler control. Increase the small coal-fired boilers (including coal-fired boilers and furnaces tea, operating the stove, grain storage and drying equipment, coal-fired facilities) elimination efforts. According to the principle of small demolition and Japan to promote clean energy use, developing the approach to co-ordinate the establishment and management of inventory ledger. Strengthen ecological environment, housing and urban construction, industry and information technology, market regulators linkage, strictly control new coal-fired boilers. 2018, 10 steam tons / hour (or 7 MW) coal-fired boilers and focus on the completion of the phase-out of county level and above all the urban area and old inefficient coal-fired boilers small tasks within the industrial park, small demolition boiler mission of 111; 2019, to phase out coal-fired boilers to further improve standards, expand the scope to promote the elimination of urban built-up area of 20 steam tons / hour (or 14 MW) and coal-fired boilers, in addition to special planning according to urban heating heating boilers other than essential to retain, urban built-up area 20 steam tons / hour (or 14 MW) coal-fired boilers to be eliminated and all.
4, the development of industrial furnaces governance special action. Development of industrial furnace remediation plan to carry out an intensive investigation, the establishment of various types of industrial furnaces inventory management. Increase the non-compliance of industrial furnaces out of efforts to speed up the elimination of small and medium gas furnace. Encourage industrial furnaces use electricity, natural gas and other clean energy or heat from the surrounding power plant. Key areas banned fired stove, the coal-fired cogeneration substantially eliminated heating pipe network coverage heated oven (furnace); out hearth diameter of 3 meters fuels gas furnace, a fixed bed to increase fertilizer industry intermittent coal gasifier reform efforts; focus on the use of gas furnace industrial park, they will not have to switch to natural conditions, should build a unified clean coal gas central principle; prohibition blended with high-sulfur petroleum coke. The industrial furnace governance as key tasks of environmental inspectors, who have not included in the list of industrial furnaces were included in the autumn-winter peak load shifting production program.
