environment plan for boiler projects
This wns series steam environment plan for boiler projects produced by CBM is a full-automatic, horizontal type, internally fired, three pass, packaged natural gas boiler. The perfect full-automatic control device and protect equipments are equipped to regulate the water level automatically and to warn or shutdown while the water level higher or lower the demand level. The steam pressure automatic control device warn at the time of overpressure. Automatic-ignition device, auto- adjusted burner fire and protection while flameout will guarantee the safe running of the boiler.
Hot water environment plan for boiler projects soda treatment guidelines have soda water boiler surface is more annoying things to look at how to deal with today. First, the boiler evaporation surface (surface) rises soda together, shake up and down the occurrence of a lot of foam and roll scene, called priming. When priming occurs, the water table is also frothed, sharp shaken water, soft drinks is difficult to distinguish the boundaries; sharp decline in temperature superheated steam; when severe, water hammer occurs in the steam pipe. Priming of the full consequences of the same water, with water vapor will decrease the quality of steam, superheater fouling and formation of water hammer oscillation, damage or affect the safe operation of the superheater steam equipment. Second, the soft drinks were vacated, have composed the following two factors: 1) poor quality water pot. Due to poor quality of feed water, sewage and other factors wrong, formed pan suspended in water or salt content is too high, the base is too high. Due to the higher-containing soft drinks near the parting, boiler water concentration of the surface layer, a large pot of water viscosity, bubbles rise to the resistance increases. When the load is added, increased vaporization, many adherend bubble barrier layer in the vicinity of the water surface too late pot leave out a lot of foam constituting the water surface of the pot roll up and down. 2) adding a load and rapid pressure drop. When the water level is too high, excessive load is added, the pressure drops too fast, the evaporation surface will increase, the water formed and shaken with water vapor. 3) Adoption of the approach found Priming: at the moment of combustion should be weakened, drop load, small off main steam valve; hydrophobic reinforcing superheater and steam pipes; fully open the drain valve after another, and turn on the water drain valve open as expected, Sheung together, to improve the water quality of the pot until the water quality improvement, water level clearly can gradually recover normal operation. Third, to prevent the priming approaches: 1) strengthening the management of water quality, strict control of boiler water salinity and grease, suspended solids; 2) according to boiler water analysis, successive emission control; 3) open to the main steam supply should be slow steam valve; 4) and the boiler steam pressure should be lower than the base pipe pressure 0.05Mh; 5) put into operation before the new boiler must cook oven. There is the above method of treating the surface of hot water in the soda boiler.
Three reasons for the low nitrogen environment plan for boiler projects was widely welcomed: the low nitrogen boiler by adding a low nitrogen processing technology, based on the safe and stable operation, but also has the unique advantages of clean and green, to obtain people's praise, then, this high-quality, durable boiler popular low nitrogen because in the end, what does? 1, adding flue gas recirculation technology professional low nitrogen boiler flue gas recirculation technology is used primarily to reduce by adding an appropriate amount of flue gas in the region of the flame burning temperature, and the combustion products of these fumes is added to the combustion zone to recirculated flue gas and to achieve the purpose of reducing the nitrogen gas generated. 2, energy-efficient and reliable low nitrogen smoke tube boiler used in the seamless pipe is of high quality and durable, it can ensure the safe operation of the exhaust passage up to a certain extent, but, no matter how much the intensity of the combustion, seamless the pipeline can be a good exhaust gas, in addition, good quality and low price of low-nitrogen boiler is further characterized by energy-efficient, capable of efficient operation at low load state, while saving energy consumption is also reduced costs. 3, the use of advanced Internet technology low nitrogen boiler control using the most advanced Internet technology to control, but also for data transmission and real-time monitoring, so that when the low nitrogen boiler operation in the event of any fault, enterprises can grasp the first time and understand the reasons for failure, and promptly make the appropriate adjustments to the machine, thus improving the production efficiency of the equipment and for enterprises to win greater economic benefits.
Inner Mongolia Autonomous Region for the winter heating long-term, large coal consumption of the actual situation, "strictly control coal pollution" as a top priority to improve air quality.
According to statistics, in 2018, Inner Mongolia fully complete the remaining 10 127 tons of steam / hour and small coal-fired boilers out of the task-level urban built-up areas; Hohhot, Baotou, Wuhai more polluting coal and other built-up urban area start 35 steam tons / hour and the phase-out of coal-fired boilers.
Inner Mongolia this year also completed shantytowns 142,000, an increase of central heating an area of 11.36 million square meters, the "coal to gas," "coal to electricity" pilot project, the region cut loose coal burning 636,300 tons.
In addition, in order to fight the "Battle of the sky" tough fight, Inner Mongolia this year has introduced the "Atmospheric Pollution Prevention Act," "Blue Sky Battle win three-year action plan to implement the program" and other local laws and regulations.
From January 2018 to November, Inner Mongolia Autonomous Region average PM2.5 concentration of 30 micrograms / cubic meter, down 6.3%, the ratio of the number of good days to reach 83%.
