Premix low nitrogen condensing boiler characteristics ① power 550kw, 700kw, 1100kw. ② The premix condensing technology, air-fuel ratio is more reasonable. ③ The silicon aluminum alloy heat exchangers, high heat transfer efficiency and corrosion-resistance. ④ High efficiency: thermal efficiency of up to 108% (water 50 ℃, backwater 30 ℃). ⑤ Low Emissions: N0x emissions up to 30mg / m3 or less (standard conditions). ⑥ microcomputer intelligent control, the operation more convenient. ⑦ stable operation: adoption of the European advanced accessories to ensure safe and reliable operation. Ease of installation and transportation ⑧: small size and light weight. ⑨ low maintenance costs.
To protect the economic development of enterprises, production safety running smoothly, according to Qingyang County in Anhui Chizhou municipal government air pollution control requirements, coal-fired boiler inspection pull the plug on a regular basis in October 2018.
Qingyang County Market Supervisory Authority for the county a number of companies were visited research to understand the company's current production operating conditions and problems, start from regulatory functions, for enterprise development to provide quality services, reduce business costs.
Special equipment boiler pressure is high risk, than a regular inspection cycle must immediately stop using, but they are also necessary for the production of business equipment, once the shutdown enterprises will face shutdown. Looking at business owners anxious eyes and counties actively discussing with the city center expert special inspection, and according to regulations, to quickly determine a set of effective programs and promptly inform each enterprise.
Through contact with the surrounding counties and cities to understand the relevant units of the boiler fuel change fees and counties take the initiative and boiler companies approached agreed upon with the use of rehabilitation programs, a significant reduction in transformation costs. Up to now, Qingyang County has completed 12 boiler fuel change work, the cumulative cost of more than 60 million.
Poor water quality means that the water contains more impurities. The raw water in the boiler feed water may contain impurities such as suspended solids, colloids, organic matter, inorganic salts, heavy metal ions, and dissolved gases. If this water is not treated, it will bring the following hazards once it enters the boiler: 1, scaling When suspended solids, colloids, and inorganic salts are heated or exceed their saturated concentrations, they will settle out and form sludge and scale, which will greatly affect the heat transfer efficiency of the boiler and the boiler water circulation, fuel waste, damage to the heated surface, decrease in boiler output, and cleaning. The amount is increasing. The amount of washing is increased. It was determined that there was a 1 mm thick scale, a waste of 10% fuel, and a 10 kgf/cm2 boiler. When operating without scale, the wall temperature was 280. C, after the 1 mm thick silicate scale is formed, the wall temperature rises to 680 due to the increase of thermal resistance. C, at this time, the strength of the steel plate is reduced from 40 kgf/cm2 to 10 kgf/cm2, which causes the boiler pressure to drop, and the furnace wall is cracked, bulged, and even broken. In the case of severe scaling, serious accidents such as furnace tubes, waterways, furnace shutdowns and boiler explosions may occur, and the freezing of cracks in production equipment and heating equipment may occur from time to time. When chemical cleaning and descaling, improper pickling or pickling frequently affects the life of the boiler and pollutes the environment.
2, corrosion: Poor water quality causes metal corrosion, which causes damage to the metal components of the boiler. Metal corrosion products form new structural substances, and scale corrosion occurs, which accelerates the damage of metal components.
3, soda water together: The phenomenon that water droplets in the furnace of a steam boiler are carried away by a large amount of steam is called soda water. One of the reasons for this is that the water contains more impurities such as sodium chloride, sodium phosphate, silicide, and organic matter. The co-existing of steam and water will cause serious pollution of the steam. The superheater pipe and the steam flow pipe will accumulate salt. In severe cases, the pipeline will be blocked, the steam temperature will drop, and water and corrosion will be broken.
4, caustic embrittlement: It refers to irregular damage-explosion caused by low carbon steel, alloy steel and stainless steel when the tensile stress exceeds the yield point and is in contact with concentrated caustic soda solution.
And condensing boilers generally use clean energy such as natural gas as a fuel, has great environmental protection. In addition, the condensing boiler also has other advantages, with a look. A modular operation more simple design using a condensing boiler combined into a plurality of sections of the design pattern, the mounting structure is simple, the use of flexible and convenient. Simply refers to: split the original single large boiler dry N plurality of small boilers. This design allows the boiler by the number of "simple parallel combination" may reach the size of any single boiler, so many users choose this status condensing boiler to replace the various types of heating and china factory hot water boilers. Second, to reduce maintenance costs condensing boiler heating system boiler, including its internal control system and automatic gas control system, no working system can achieve a high degree of artificial effect, greatly reduces the labor costs. And condensing boiler through continuous optimization of design, process design condensing boiler, matching equipment level to a new level, to enable them to better serve the industrial production. Third, due to the smaller footprint smaller storage capacity of a condensing boiler, the temperature of heat up very quickly, only a few seconds, without generating excess heat loss. And because of its small storage capacity, so that the condensing boiler smarter structure, small volume, light weight, even if it is placed in the roof is also very convenient. And the use of condensing boilers can also save investment investment.
