One yuan complex Unrestraint years, the spirit of renewal long. The new year began with new challenges, party fast Group 2019 Spring Annual Meeting held January 29 at 3:30 pm in Anyang, Henan Hong Rui Hotel, all my colleagues gathered to congratulate the New Year.
Greater than 65t / h industrial boiler of what air pollutant emission standards should be executed? A: The State Environmental Protection Administration, Central Division-standard  No. 012 document pointed out that the emergence of a small number of parameters currently higher than GB1921-80 "industrial food industrial usage coal fired steam boiler parameters Series" and GB3166-82 "hot water boiler parameters Series" layer burning, stoker boiler, regardless of its use Zanan GB1327-91 execution. Therefore> 65t / h or more (except coal, circulating fluidized bed, and fuel, gas fired boilers) industrial boilers should be performed "boiler air pollutant emission standards."
Details of operation of the boiler 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.
Select gas food industrial usage coal fired steam boiler What are the benefits? 1: The biggest benefit is the economic use of gas steam boiler can save a lot of material costs for the business users do not need to spend lots of money to purchase a large amount of coal fuel, just use good cleanliness of natural gas can be released by burning used steam. Gas can also improve the thermal effect of reducing the material input costs of users. 2: Security is well known that natural gas is the safest non-polluting fuel cleanliness good a non-toxic, unlike gas or liquefied petroleum gas leak after precipitation on the ground will burn even cause accidents. 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 use is the most convenient one, so will much of each enterprise users of all ages. Are used in natural gas pipelines like the convenience of home tap water, and sustainable use will not be any trouble. 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 have the black bottom of the pot and no air pollution. So compared to other boilers in use is the cleanest one way, whether for work or residents of the surrounding operation of the enterprise itself or cleaner can not affect physical and mental health.
