steam coal fired boiler water budget 2mt capacity
Details of operation of the steam coal fired boiler water budget 2mt capacity details chemical energy chemical energy Note 1 Note that operation of the boiler, fuel delivery is controlled with respect to the thickness of the layer of coal-fired boilers, the actual operation, the particles of different sizes on the same coal seam, unreasonable distribution, uneven ventilation, combustion is not uniform. The method can be employed uniformly stratified combustion to coal, to improve seam incomplete combustion: first administration of large particles of coal in the lower layer, the upper layer after administration minimal, large particle surface area of small particles of coal, the need to burn a long time, this time is in the air the highest concentration of oxygen lower position; the other hand, small particles of coal on top, large surface area, a low oxygen concentration, full use of excess air. 2, the flow regulating damper excess air ratio is too large, a large loss of smoke; excess air ratio is too small, incomplete combustion loss is large, and therefore need to properly regulate the air flow to minimize loss of two or more. Usually in the flue gas analyzer backpass smoke, the control amount of wind of carbon monoxide is reduced to a reasonable value. For unconditional for gas analysis, empirical judgment by the naked eye can see the flame in the furnace, the flame pale described excess air amount; brown opaque flame, smoke black smoke indicates incomplete combustion. 3, there is a 1mm thick scale surface water quality management experiment boiler heating surface, waste of fuel from about 3% to 5%, in the presence of 3mm thick scale, waste of fuel of about 5% to 10% . Water two general steps: pre-treatment, ion exchange or reverse osmosis. 4, cleaning blowdown gray scale or fouling deposition in the heating surface, increased heat resistance, reduced heat absorption wall, to improve the furnace exit gas temperature, boiler output decreased, but to increase the amount of cast coal, causing furnace exit gas temperature further improve a vicious circle. Therefore, timely cleaning clear dirt is particularly important. 5, the energy efficiency of the heat insulation testing industrial importance boiler showed small boiler in the case of good thermal heat radiation loss is about 3%, if the wrong selection insulation material, the thickness is too small, or even damage, does not include local heat, heat losses will be higher, the boiler has been running, has been caused by waste heat into the air. When the shutdown check whether the furnace wall insulation bricks off; isolated brick flue check is complete, to avoid shorting the flue gas; outer portion boiler, steam pipes and other insulation damage to be repaired; when heat insulation, low thermal conductivity of the material ( i.e., materials with good thermal insulating properties) on the inner layer having a better thermal insulation effect; respond to the economizer outer insulating layer for laying under conditions permitting. 6, to solve the problem of air leakage air leakage boiler boiler unit during operation is a common problem, the need to ensure the tightness of the boiler, furnace air leakage above all, do not close the site to check the furnace wall, door, inspection holes, etc., can be candles law, candles near these places, to observe whether the candle flame inward deflection to judge. Second leakage tail heating surface, the flue stack leakage mostly welding cracks, elbow bend, the expansion joints wear wear; mostly air superheater corrosion or wear leading to leakage through the pipe, the boiler shutdown should focus an examination.
How to improve the energy efficiency of industrial steam coal fired boiler water budget 2mt capacitys 1, focusing on the transformation of practicality (1) above to recover waste heat can be effectively used. For example: high temperature organic heat boiler flue gas, but the process does not require the production of steam and hot water, attention should be considered heated by flue gas waste heat recovery techniques combustion air. (2) improved gas boiler should focus on energy-saving technologies improve the automation level of combustion control, precise control of the combustion state. (3) Consider first the application of energy-saving technologies and sophisticated equipment. 2, considering the technical nature to further improve the thermal efficiency of industrial boilers, it is necessary to consider new energy-saving technologies and equipment. Advanced (1) energy conservation technology and equipment, difficult to implement. Such as: waste heat recovery heat exchanger and the new technology: heat pipe technology, the condensed waste heat recovery technology; new water treatment device: microbial fouling and electromagnetic processing techniques (e.g., hydraulics); combustion automatic control technology. (2) spraying pulverized coal combustion technology (stratified combustion mode and suspension-fired boilers) design, construction and operation of high demand management, oxyfuel technology, such as high temperature air combustion technologies require large investments. 3, forming a complete transformation handle (1) must be considered boiler energy saving, heat insulation of synchronization is complete, sealing, and improved methods of burning fuel adjustment, and the fuel air distribution system of the inverter, reduced nicotinamide tube improved resistance to treatment. (2) pay attention to clean the boiler heating surface, and providing technical improvements boiler water, slag, ash, etc., to ensure that the boiler has good heat transfer properties. (3) the necessary training for technical operations and daily management of energy-saving equipment.
The latest was informed Tongling Municipal People's Government issued the "Notice on Tongling City to win the Battle of Blue Sky embodiment", as follows.
First, deepen industrial pollution control
Continuing to promote a comprehensive industrial pollution discharge standards, increase penalties and excessive joint disciplinary efforts, not discharge standards of the enterprise to suspend for rectification according to law. Implementation covering all stationary sources of emissions permits enterprise system, before the end of 2020 to complete the trade provisions of the license issued discharge permit management directory.
Carry iron and steel, cement, nonferrous metals, thermal power, coking, casting and other key industries and ports, shipping, coal-fired boilers fugitive emissions investigation, the establishment of management accounting, before the end of 2019 to complete the material (including waste) transportation, handling, storage, transfer and process fugitive emissions such as in-depth treatment.
Second, the continued implementation of the total coal consumption control, strict implementation of coal consumption reduction instead. By 2020 the city's coal consumption control in less than 13 million tons of coal accounts for the proportion of total energy consumption to decline further. Strict implementation of new coal projects coal reduction instead. Added support for the power industry outside of iron and steel, chemicals, nonferrous metals and other industries coal projects, the implementation of coal consumption reduction of 1.5 times alternatives. Increased focus on bulk coal remediation efforts. High-pollution fuel combustion zone ban bulk coal sales all clear.
Third, the implementation of the "coal to gas" and "electricity instead of coal." Strengthening the capacity of natural gas supply security, promote glazed tiles, casting and other industries natural gas instead of coal gasification project, orderly implementation of coal-fired facilities from coal to gas. Combined with regional and industry energy characteristics, and actively promote the implementation of "electricity instead of coal" in the field of industrial production, transportation, agricultural production, living and so on.
Fourth, continue to strengthen the supervision of the boiler. Consolidate the results of rectification of small coal-fired boiler, make sure the rebound does not occur, a citywide ban on new 35 tons of steam per hour and coal-fired boilers. Increase efforts to eliminate small coal-fired boilers. Dynamically updated list management coal-fired boiler, built-up area City 35 tons of steam per hour coal-fired boilers by the end of 2019 total phase-out or implementation of clean energy alternatives; retention of six chemical companies 2 130 tons of steam per hour of coal-fired boilers to complete all energy saving and ultra-low emissions transformation.
Fifth, strengthen the bulk coal governance. Strictly implement the "Interim Measures for commercial coal quality management" (National Development and Reform Commission Order No. 16) and technical standards for coal-fired boilers, in-depth implementation of bulk coal remediation crucial action, and strictly implement the ban on burning areas prohibit the use of high-polluting coal for fuel measures. To strengthen the management and control of coal-fired coal. Ongoing monthly coal quality sampling, and promote enterprises to increase coal-fired coal reform efforts.
Mature technology in biomass steam coal fired boiler water budget 2mt capacity, our SZL series chain grate boiler widely available renewable energy technology that generate steam from 6 to 40 ton to any industry factories, facilities, plants, etc. What’s more, our ZG Boiler can can supply larger capacity and high pressure circulating fluided bed, power plant boiler, biomass boiler, produce steam for electricity or other requirements. A fully automated operation system, similar to those used for conveying feed and grain on farms, delivers biomass pellets from an outdoor silo to the boiler’s hopper. At a rate predetermined by user-controlled settings, a fuel-feed system then delivers the pellets to a combustion chamber. Pellets are burned using staged combustion air injection (a process that reduces NOx ). A cyclone separator knocks out particulate matter that is then removed by an on-line, automated mechanical cleaning and ashremoval system. Usually, biomass fired cfb boiler has higher thermal transferring efficiency than chain grate boiler. And both of them can burn mixed fuels like wood pellet and coal; bagasses and coal; palm shell and coal etc.
