WNS4 2 MW Diesel Oil or Gas Fired Hot Water Boiler

Technical characteristics: the overall cost of natural gas boiler is half the coal-fired boilers, and operation costs are four times as coal, a ton of steam needs to burn about 80 cubic meters of natural gas, and coal-fired no more than 0.185 kg, the economic accounts will be considered . Select the gas boiler it under certain conditions choice of last resort. As well as on the performance of the gas is better than coal. In principle, they are heat transfer equipment, the difference is that on combustion, complex grate or coal, coal preparation, etc. as well as coal needs, while gas only burner that simple. Use of cleaning gas boiler: boiler after a long run, the inevitable emergence of scale, mainly due to the scale of the problem of corrosion, formation of boiler feed water with hardness components, through subsequent high temperature and pressure continuously concentrated by evaporation in a furnace a series of physical and chemical reactions that ultimately form a hard heating surface, a dense scale, resulting in reduced heat transfer and the effect of corrosion under the scale factors, will result in reduced boiler waterwall furnace heat absorption, furnace outlet temperature of the boiler is increased, so that increased boiler losses. After scaling while reducing the heat transfer within the water wall, water wall tube wall temperature may lead to increased water wall lead to burst pipes, affect the safe operation of the boiler. The first of scale is detrimental boiler, the boiler is the main cause of accidents, the danger main problems: wasting a lot of fuel: Because only one of very few steel thermal conductivity of scale, so when the heating surface fouling will heat blocked, in order to maintain a certain boiler output, it is necessary to increase the temperature of the side of the fire, so that the external radiation and flue gas heat loss. Now it can be used efficient and environmentally non-corrosive cleaning agent gas boiler cleaning, cleaning Fu World Tektronix cleaning agent scale was completely dissolved, the equipment expose the metal tube primary colors, because the reduction of algae and biological sludge fouling effect. At the same time stripping the role of iron oxide and iron oxide Asia, extended gas boiler service life, reduce energy consumption and improve productivity.

Zhengzhou Sunrise Optoelectronics Technology Co., Ltd. by the Dongxu Group, Henan Province, the state-owned asset management companies and Zhengzhou Investment Holdings Limited jointly made, mainly engaged in flat panel display and solar industry design materials, manufacturing and sales operations. Sunrise Optoelectronics project has been put into a production line, the second phase will continue the expansion, three new production lines to meet the production needs of Project Phase II, Sunrise Optoelectronics urgent need to increase new boiler equipment. After investigation and screening of a number of boiler brands, determined to cooperate with the fast boiler, steam signed a 10-ton integrated condensing gas steam boiler (WNS10-1.25-Y.Q).

Although the fuel of 58MW circulating fluidized bed wns4 2 mw diesel oil or fired hot water boiler is also coal,but it adopts CFB circulating fluidized bed combustion technology,and mixture of gas and solid, and the fuel particles and circulating combustion, the fuel particle residence time in the furnace is lengthened, the combustion efficiency can reach 97-99%. The boiler thermal efficiency up to 85%, higher than the national standard of 15-20 percentage points, has remarkable energy saving effect and economic benefits. In the society to reduce the energy waste, but also to reduce dust emissions, the social benefit is great.

Common wns4 2 mw diesel oil or fired hot water boiler Accident (c) hot water boilers common accidents in addition to accidents, explosions, that there is a tube rupture. So what causes hot water boiler tube rupture is what kind of solutions does the cause of the hot water boiler tube rupture:?? Quality (1) boiler water is poor, resulting in the accumulation of impurities in the boiler, severe corrosion and other problems attached boiler tubes, not a long time to clean up in time, lead to the phenomenon of burst pipes. Material selection (2) non-compliance boiler tubes and so lead to pipeline pressure less able to cause the occurrence of burst pipes phenomenon. (3) In addition, due to the boilers used for a long time, parts of aging, wear and other phenomena more serious, there will be burst pipes phenomenon. (4) When pulverized coal boiler, oil, gas hot work, operational errors can cause the collapse of the furnace walls and furnace tube bore explosion. Solution: (1) timely boiler attached to the wall of debris to clean up after the shutdown. (2) severe damage to the superheater, boiler shutdown immediately related operations hot water, and then timely maintenance. In short, boiler tube rupture is one of boiler accident hazards of large accidents, hot water boiler during operation, should be timely maintenance, to avoid unnecessary security risks.
