Scale chemical plant boiler scale formation of harmful chemical hazards boilers formed in the boiler 1, the boiler steel pipe is due to overheating burning boiler known as sources of hazards, the key is the thermal conductivity of the boiler very poor. Thermal conductivity material size generally used to measure the thermal conductivity, thermal conductivity smaller scale than the boiler plate several tens to hundreds. When the size of the enemy boiler heating surface, heat transfer conditions deteriorate, so that fire and smoke tube well water can not absorb heat, the surface temperature of the heating, the metal strength, easily lead to the boiler tube expansion, deformation and burst pipes. Further, after the furnace tube fouling cross-sectional flow area decreases, resistance increases circulation, and disruption of normal cooling water circulation of the boiler, resulting in the loss of the combustion furnace tubes. 2, the boiler output decreased fuel waste is contaminated when the boiler, the boiler heating surface heat transfer becomes poor, the exhaust gas temperature will rise. Since the scale low thermal conductivity, hindering heat transfer, thereby reducing the thermal efficiency of the boiler, fuel consumption increases, reducing the yield of the boiler. Experimental proof for a working pressure of 1.3 MPa boiler scale mixing to form 1mm thick, wasting fuel may be 5% to 8%. 3, increase the amount of maintenance the boiler and endanger the safety of the boiler heating surface after scaling is very difficult to remove, the need to frequently clean dirt or boiler pickling, and pickling boiler is likely to cause corrosion to the boiler, while the pickling liquid waste to the environment caused by emissions pollution not only damages the boiler life, but also requires a lot of manpower and material resources for maintenance, and threaten personal safety, the safety impact of the production.
Food is food industry is human life industry, but also an ancient and eternal evergreen industry. Industrial 2ton 4ton 6ton steam boiler as an integral part of the chain, is mainly used for processing of distillation, extraction, sterilizing, drying, curing and other processes. Anqing City, Anhui Province is located in the Want Want Foods Co., Ltd. mainly engaged in all kinds of puffed food processing and manufacturing and sale of steam boiler steam delivered directly or indirectly in contact with food, thus requiring the steam quality is very high. Due to expanding production needs, Want Want Foods in urgent need of a boiler plant to provide high-quality steam. After a comprehensive understanding of the boiler industry, determined to cooperate with the fast boiler. Want fast square perennial cooperation with the country's food company, it has considerable experience of cooperation. By understanding the needs of the Want Want food production, providing a whole 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
When gas 2ton 4ton 6ton steam boiler in operation, protection is very important to reduce reasonable protection device failures and maintenance problems. Over-temperature alarm device on the gas steam boiler, its a great extent on which is mounted directly on the local outlet of hot water boiler, steam boiler water temperature in the gas temperature exceeds the specified time, that is, will automatically alarm, on this point, then, to a large extent, that is, to remind staff to take steps to weaken stoker combustion. Over-temperature alarm on the gas and steam boiler unit chain after chain protection, to a large extent on its upper that is at the same time should be to over-temperature alarm and automatically cut off the fuel supply and stop the drum, the wind, which when, that is, to prevent the occurrence of over-temperature boiler equipment caused by damaged phenomenon. Low water level and low water level alarm interlock protection device on the gas steam boiler. Also refers to the boiler water level higher than the highest among the security level or time below the minimum safe water level, water level alarm will automatically alert is to a large extent, the fireman remind personnel to take measures to prevent accidents . Finally, the protective device on the gas steam boiler, in fact, is there flameout protection device, on this point, then, in fact, is that we should pay attention to when the gas furnace boiler flameout occurs, the device will play a role on the boiler flame protection at the same time, it is able to cut off the fuel supply to a large extent, and will send a corresponding signal.
