All along, Zhangjiakou City, Hebei Province, took the central environmental protection supervision "look back" as the main problem of feedback opportunities to enhance the ecological environmental protection, pollution prevention and fight tough fight, active rectification, hard to rectify, resolute reform, promote the environmental reform task completed on schedule. We understand that in 2018, Zhangjiakou City Daly to promote projects cut coal, the accelerated clean alternative to coal consumption year on year in 2017 to reduce 1.04 million tons.

For unfinished "2017, the province's energy cut carbon coal down the main points of" cut annual coal requirements of mission objectives problem, Zhangjiakou City, supervisors coal companies cut coal, high quality coal, strengthen energy-saving technological transformation, to fully grasp the total coal consumption control and reduction of bulk coal.

The strengthening of key coal enterprises cut coal, to promote energy-saving technological transformation projects, several key coal enterprises to continuously improve energy standards. And vigorously promote the project minus coal, coal production in 2018 to defuse 8.6 million tons, out of coal-fired boilers 1663 units. Accelerate clean coal alternative, clean winter heating selected pilot cities in northern, rural complete "electricity instead of coal", "substitution of gas for coal" 6971. And vigorously develop renewable energy sources, as of 2018 the city's renewable energy installed capacity of 13,454,800 kilowatts, accounting for 74.2% of all electricity installed capacity, the highest in the country.

The use of gas industrial coal fired steam boiler manufacturer aurangabad added to give businesses what benefits? National emphasis on energy conservation increased year by year, which also contributed to the gas steam boiler flourish among industry, under the premise of environmental policies and to efficiency gains, companies are willing to choose both energy-saving, and high thermal efficiency of gas-fired boiler. Gas steam boiler in addition to providing sufficient high-temperature steam, but also can reduce fuel cost by reducing the combustion load input. The use of gas steam boiler will bring any significant benefits, let's take a look. 1, the biggest benefit is the economic use of gas steam boiler can save a lot of fuel costs for businesses, you do not need to spend lots of money to purchase a large amount of coal fuel, just use good cleanliness of natural gas will be able to output enough steam; they also do not We need the fuel storage site, only need to connect to the pipeline. 2, security is well known that natural gas is a very safe and stable, non-toxic and pollution-free, good cleanliness of fuel, liquefied petroleum gas or gas leak after not deposited on the ground, and even cause accidents will burn again. 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 the use, operation is very convenient, so will much favored by all walks of life. Because the use of all natural gas pipeline, a sustained run without any problems. 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 produce black bottom of the pot, there is no air pollution. Thus, in use, compared to other boiler is the cleanest way.

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% [3]. 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.

As a leading industrial coal fired steam boiler manufacturer aurangabad manufacturer in China, ZG Boiler keeps manufacturing high quality industrial steam boiler for all industrial area. Among one of IBR steam boiler manufacturers, ZG Boiler researches, engineers, manufactures and sells industrial steam boilers for a wide range of commercial and industrial applications. Different division, different steam boiler. For example, because of different fuels, our main products can be IBR biomass fired steam boiler, IBR coal fired steam boiler, IBR gas fired steam boiler, IBR oil fired steam boiler, IBR CFB steam boiler, etc. Those IBR steam boilers also can be divided into single drum steam boiler and double drum steam boiler. Our honestly consumers can choose horizontal steam boiler and vertical steam boiler. Here, as a IBR steam boiler manufacturer in China, I wound like to introduce IBR steam boiler in fuel difference.
